What business models are working in climate tech?
In our climate tech market deck, you will find everything you need to understand the market
SUMMARY
The climate tech business models working best today are contracted infrastructure, hardware with recurring software or service, energy-as-a-service, operational energy software, financed customer subscriptions, and industrial technologies that plug into assets customers already own.
The common thread is not simply decarbonization. The strongest businesses solve an economic or operational problem first: cheaper power, grid reliability, lower operating costs, access to critical materials, compliance, or avoiding a large upfront investment.
Capital structure is becoming part of the business model itself. Moving from venture equity to project debt, securitizations, tax-credit monetization or infrastructure capital is one of the clearest signs that a climate technology is becoming financeable infrastructure.
Battery storage is already a mainstream power market, but that does not mean every storage supplier has a great business. Falling costs create demand while also intensifying price pressure, which is why Tesla can earn healthy energy margins while Fluence can carry a record backlog at a 5.1% quarterly gross margin.
Recurring revenue gets much more valuable when it is attached to physical infrastructure already installed at the customer. ChargePoint's subscription economics, Fluence's service backlog and Kraken's utility software all show how the installed base can keep producing revenue long after the initial deployment.
Owning or operating assets can be more attractive than building them once. Ameresco's energy assets and O&M activities generate a disproportionate share of EBITDA even though project construction still produces most of the revenue.
Long-term contracts are often what make new climate infrastructure bankable. A binding power-purchase or offtake agreement can support debt financing; a large pipeline or framework agreement is useful, but it does not carry the same financing weight.
Carbon removal has become a real contracted market, but it is still unusually dependent on one buyer. Microsoft's scale proves that long-duration offtake can create a market, while the concentration also shows why the sector is not mature yet.
Industrial licensing works best when the technology fits into infrastructure customers already own and creates an operating benefit. CarbonCure is a strong example because concrete producers can reduce cement use, keep their plants, and add carbon-credit revenue on top.
The weakest models still combine heavy upfront capex with uncertain demand and an expected green premium. Climate businesses are in a much stronger position when the customer would still have a reason to buy even if the carbon benefit disappeared from the sales pitch.

When can we honestly say a climate tech business model is working?
A climate tech business model is working today when customers keep paying, the economics hold up as volume grows, and deployment can eventually move onto cheaper capital than venture equity.
That definition is stricter than having a clever technology, a large pipeline or a few big customers. Climate tech has plenty of companies that have proved demand while still struggling to make good money from that demand. Fluence is a good example: its latest quarter included $1.44 billion of new orders and pushed backlog to a record $6.4 billion, yet GAAP gross margin fell to 5.1%. The storage market clearly wants what Fluence sells; the harder question is how much profit Fluence can keep from each project.
The financing model matters just as much. Fervo Energy reported a $55.9 million net loss in its latest quarter and spent $226.5 million on capital expenditure. At the same time, banks committed $421 million of non-recourse debt to the first phase of its Cape geothermal project. Those facts can coexist because the project has reached a stage where lenders are willing to finance its future cash flows separately from Fervo itself.
We therefore use three practical tests throughout this article. Customers need an economic reason to keep buying. The company needs a credible path to earning money from each additional customer or asset. And a capital-intensive company eventually needs banks, infrastructure investors, tax-equity providers or customers to finance most of the physical deployment.
That last test separates many climate winners from companies that simply keep raising larger equity rounds.
Why is climate tech spending at record highs while startups still feel squeezed?
Climate tech is attracting more money than ever right now, although most of that money is chasing deployment, infrastructure and proven businesses rather than early-stage climate startups.
BloombergNEF calculated that global energy-transition investment reached a record $2.3 trillion in 2025, up 8% in a year. Electrified transport absorbed $893 billion, renewables $690 billion and grids $483 billion. The International Energy Agency expects total energy investment to reach $3.4 trillion in 2026, with about $2.2 trillion going into clean-energy technologies and infrastructure.
Those are enormous numbers. Yet BloombergNEF also found that venture funding for climate-tech startups declined for a third consecutive year in 2025. The $77.3 billion of equity raised by climate-tech companies increased sharply overall because public equity and larger transactions recovered.
Debt tells the story even more clearly. Energy-transition debt issuance reached about $1.2 trillion in 2025, 17% more than the previous year, with both corporate and project financing up around 20%.
So climate tech currently has plenty of capital. The difficult part is reaching the point where a company qualifies for the cheap pools of it.
Investors have become much less willing to finance years of factory construction, technical risk and operating losses on the assumption that customers will eventually pay a green premium. They are far more comfortable financing a battery project with contracted revenue, an established grid supplier, a solar portfolio with predictable payments or a mature technology that solves an immediate power problem.
The funding market has split in two. Proven infrastructure is attracting trillions. Experimental companies still have to fight for equity.
As this chart shows, and as featured in our climate tech market deck, search interest in climate change has continued to rise
Is selling climate hardware actually a good business model today?
Selling climate hardware can work very well today, although the economics vary wildly and large sales volumes can hide weak margins.
Tesla shows what successful climate hardware can look like. Its energy business deployed 13.5 GWh of storage in its latest quarter and generated $3.14 billion of quarterly revenue. Energy gross margin was 20.4%. That margin had fallen sharply from the previous quarter because of warranty costs, changing tariff benefits and lower storage pricing, yet Tesla still demonstrated that large-scale climate hardware can produce meaningful gross profit.
Fluence sits at the opposite end of the margin spectrum right now. Its latest quarterly revenue reached about $650 million and order intake almost tripled year over year to more than $1.44 billion. Revenue growth came with only a 5.1% GAAP gross margin, down from 14.8% a year earlier.
EV charging shows how brutal hardware economics can become. ChargePoint generated $216.5 million from networked charging systems in fiscal 2026. Those systems cost almost $200 million to deliver. Using the figures in ChargePoint's annual results, we calculate a gross margin of roughly 8% on that part of the business. Its subscription business looks completely different, as we will see below.
The practical lesson is that climate hardware works best when manufacturing is standardized, customers need the product for economic or operational reasons, installation does not become a bespoke engineering project every time, and the company can keep earning after the equipment has been delivered.
A billion dollars of hardware revenue tells us surprisingly little on its own.

Why is battery storage working better than most climate hardware?
Battery storage is one of the clearest climate hardware winners today because the customer increasingly needs the product for power-system economics, reliability and speed, with decarbonization coming almost as a bonus.
The cost curve has become unusually favorable. BloombergNEF found that the global benchmark cost of a four-hour battery project fell 27% in 2025 to $78 per MWh, the lowest level since it started tracking the technology in 2009. Stationary battery-pack prices fell even faster, dropping 45% in a year to around $70 per kWh.
Demand is moving in the other direction. The IEA expects more than $100 billion to be invested in battery storage during 2026. Electricity investment is being pushed higher by grid congestion, renewable penetration, electrification and the rush to supply data centers. Batteries happen to address several of those problems at once.
The company data matches the market data. Tesla deployed 8.8 GWh in the first quarter of 2026 and 13.5 GWh in the second, a 53% sequential jump. Fluence's contracted storage backlog has grown from 9.1 GW at the end of its previous fiscal year to 12.6 GW currently, while its development pipeline has expanded to 45.6 GW.
We can be unusually confident here: utility-scale battery storage has crossed into mainstream power infrastructure.
That does not guarantee attractive returns for every manufacturer. Heavy competition is already pushing prices down, and Fluence's weak recent margin shows how quickly suppliers can lose economic value to customers. For the market itself, however, the business case is already strong enough to stand without a climate pitch.
| Evidence | Latest position | What it tells us |
|---|---|---|
| Four-hour battery project cost | $78/MWh, down 27% in a year | Storage economics are improving very quickly |
| Stationary battery packs | About $70/kWh, down 45% | Manufacturing overcapacity is making storage much cheaper |
| Global storage investment | More than $100B expected in 2026 | This is now an infrastructure-scale market |
| Tesla storage deployment | 13.5 GWh in the latest quarter | Large suppliers are reaching industrial volumes |
| Fluence storage backlog | 12.6 GW, up from 9.1 GW | Future demand remains very deep |

Does software really make climate hardware a better business?
Software and long-term service can dramatically improve a climate hardware business because the same installed equipment keeps generating revenue after the original sale.
ChargePoint makes the difference unusually easy to see. Subscription revenue increased 13% in fiscal 2026 to $162.4 million while networked charging-system revenue fell 8% to $216.5 million.
The economics are even more interesting. ChargePoint reported $61.9 million of subscription cost of revenue against $162.4 million of subscription revenue. We calculate a gross margin of roughly 62%. Its charging hardware generated only around 8% on the same basis.
One customer can therefore buy a charger once and continue paying ChargePoint for cloud services, network management, support and other subscriptions for years. The software layer is already producing much healthier economics than the equipment that originally got ChargePoint onto the site.
Fluence is building the same kind of second layer around utility batteries. Its service assets under management have increased to 6.3 GW and contracted service backlog to 7.9 GW. Its digital platform manages more than 22 GW.
These recurring businesses also become more useful as the installed base grows. Batteries need dispatch optimization, charging networks need software, heat pumps need control systems and distributed energy assets need aggregation. The software is tied to something expensive that is already sitting inside the customer's operations.
That is a much stronger position than selling generic sustainability software alongside the hardware.
Can pure climate software still build a strong business?
Pure climate software can still be a very good business, although the strongest companies today solve operational energy problems rather than simply helping companies talk about sustainability.
Kraken Technologies is probably the cleanest example. Octopus Energy's latest annual report shows that Kraken doubled contracted annual recurring revenue to £422 million. The platform supports more than 73 million contracted accounts across multiple countries, and recurring licensing revenue from customers outside Octopus Energy reached £102 million, up 26%.
Kraken is deeply embedded in utility operations. The software handles customer accounts, billing, tariffs, asset flexibility and increasingly other workflows. Recent contracts have taken Kraken into companies such as National Grid, while the platform has also expanded beyond energy into water and telecoms.
A utility replacing that kind of infrastructure faces a serious migration project. That gives Kraken a much stronger commercial position than a dashboard that one sustainability team can cancel next year.
Carbon-accounting software has had a harder time proving the same level of dependency. The basic task of calculating emissions is becoming easier to reproduce, large enterprise-software vendors are adding sustainability functions, and some corporate climate spending has become more cautious. Companies such as Persefoni have responded by expanding further into compliance, reporting and financial-risk workflows.
The direction is revealing. Climate software gets stronger as the climate part becomes embedded inside a process that customers already have to run.
For the best software businesses in the sector, the useful question is simple: what breaks at the customer if the software disappears tomorrow? Kraken has a strong answer.

This chart, featured in our climate tech market deck, looks at First Solar’s strategy in climate tech
Are solar-and-battery subscriptions actually working for Sunrun?
Sunrun's solar-and-battery subscription model is working, although the latest results show how sensitive the business remains to financing costs and execution.
Sunrun now has just over 1.03 million subscribers. In its latest quarter, 19,793 of 20,979 customer additions were subscribers, meaning roughly 94% of new customers chose the recurring model.
The product has also changed quickly. Sunrun's storage attachment rate reached a record 74%, up from 70% a year earlier. More than 266,000 solar-and-storage systems are now installed, representing 4.6 GWh of networked storage capacity.
The logic is easy to understand from the customer's side. A household can get solar and batteries without making the full upfront investment. Sunrun keeps the long payment stream and increasingly has the option to monetize the battery fleet through grid services.
The latest quarter also shows the limits. Subscriber additions fell 31% year over year. Net subscriber value fell sharply, and Sunrun reduced its full-year cash-generation guidance from $250 million to $450 million down to $200 million to $375 million. Management blamed lower affiliate-channel volumes, a slower sales ramp and somewhat higher capital costs.
Sunrun still managed positive quarterly cash generation when its equipment safe-harbor investments are excluded, and it recently completed a $267 million securitization backed by seasoned residential solar and battery systems.
That securitization gets to the heart of the business model. Sunrun creates long-duration household cash flows and then taps the capital markets to finance them more cheaply. The subscription model works as long as customer value stays comfortably above installation, acquisition and financing costs.
Right now, that spread is positive, although much less forgiving than the simple “solar subscription” story suggests.
Is energy-as-a-service a better business than selling projects once?
Energy-as-a-service is one of the strongest climate tech models we found because recurring energy assets and maintenance contracts can produce far more profit per dollar of revenue than project construction.
Ameresco gives us unusually good numbers for the comparison. In the first quarter of 2026, recurring energy assets and operations-and-maintenance activities represented only 23% of company revenue yet produced about 80% of adjusted EBITDA.
The latest quarter confirms that this was more than a one-quarter anomaly. Ameresco's energy-asset revenue grew 21% year over year to $75.9 million and generated $34.8 million of adjusted EBITDA. O&M revenue grew 29% to $36.2 million and produced another $9.8 million of adjusted EBITDA. By comparison, $380.9 million of project revenue generated only $17.5 million of adjusted EBITDA.
The gap is enormous. Energy assets plus O&M represented about 22% of second-quarter revenue and roughly 71% of segment adjusted EBITDA before the small “other” business.
Ameresco still needs the project business. Building an efficiency project, battery system or energy facility creates the installed base. The better economics appear once Ameresco owns the asset, operates it or remains under a long-term service agreement.
The company also entered its latest quarter with a record $6.73 billion backlog after winning $1.8 billion of new project awards. The construction work therefore feeds a much longer commercial relationship.
This is one of the climate business models we would be most comfortable calling proven today: install the infrastructure, stay attached to it, and collect recurring cash flows for years.

Can climate companies make money by owning the infrastructure themselves?
Owning climate infrastructure can create a very strong business once the assets have contracted cash flows and can be financed mainly with project-level capital.
Ameresco already shows the mature version. The company owns hundreds of megawatts of solar, battery and biogas assets, while much of the debt associated with those assets sits against the energy portfolio itself. The latest quarterly results again showed why it bothers: the energy-asset segment produced $34.8 million of adjusted EBITDA on $75.9 million of revenue.
Fervo Energy shows what the model looks like earlier in its life. Fervo is developing enhanced geothermal power plants and has signed 658 MW of binding PPAs and other arrangements that represented roughly $7.2 billion of potential revenue backlog in its first-quarter SEC filing.
The company is spending aggressively. Its latest quarter included $226.5 million of capital expenditure and a $55.9 million net loss. Fervo also expects another $850 million to $900 million of capital expenditure during the second half of 2026.
Yet the first phase of Cape Station has already secured $421 million of non-recourse project debt from a group that includes major international banks. The loan is backed by the project rather than sitting as ordinary corporate debt. Fervo has also arranged to monetize tax credits generated by the project.
That financing is arguably more important to the business model than an early quarter of corporate profitability. Once lenders agree to finance a new technology using the same broad structure they use for conventional infrastructure, each future project becomes less dependent on issuing expensive company equity.
Fervo still has plenty to prove operationally, so our confidence here is lower than with mature solar or battery assets. The financing transition itself is real.
For capital-intensive climate companies, project finance is one of the clearest signs that a technology is turning into an infrastructure business.
Do long-term offtake contracts actually make new climate tech bankable?
Long-term offtake contracts can turn an expensive climate technology into something lenders are willing to finance, which makes them one of the most important business-model tools in the sector.
Fervo's geothermal projects show the mechanism clearly. The company has hundreds of megawatts under binding PPAs with utilities and corporate buyers. Those contracts give financiers something concrete to underwrite: a customer, a volume, a price structure and a long period of future sales.
The distinction between a contract and a promising announcement is crucial. Fervo also has a 3 GW geothermal framework agreement with Google. The framework could create a huge future market, although Fervo's filings explain that each future project still needs to move through additional commercial steps. A 3 GW framework therefore has a very different financing value from 658 MW of binding PPAs.
Carbon removal uses the same basic architecture. Microsoft signs contracts today for carbon removals that suppliers will deliver over many years. Those commitments help developers raise money for projects that would otherwise need to be built before buyers existed.
Similar structures appear in sustainable aviation fuel, low-carbon materials, renewable power and green industrial projects. The more money a facility needs before production starts, the more valuable an investment-grade buyer becomes.
This is why climate tech announcements deserve different weights. A pilot shows that a customer is interested. An offtake contract can finance a factory or power plant.
For emerging climate infrastructure, that difference can decide whether anything gets built at all.
This chart, featured in our climate tech market deck, compares the main business model options for carbon management platforms
Is carbon removal a real business now, or still mostly Microsoft?
Carbon removal is a real commercial market today, but Microsoft still has so much influence that we would not call the market mature yet.
The growth is extraordinary. Climeworks' review of the 2025 market estimated that contracted carbon-removal volume rose from roughly 30 million tonnes in 2024 to 64 million tonnes in 2025. Durable carbon removal increased from around 8 million to 29 million tonnes. The report estimated total contracted market value at about $8 billion.
Microsoft alone signed agreements covering 45 million tonnes with 21 companies during its fiscal 2025. Microsoft says that volume was twice its previous fiscal year and nine times its FY2023 level.
When Climeworks compared the overall market, it estimated that Microsoft accounted for close to 90% of 2025 offtake volume.
That concentration is impossible to ignore. Carbon-removal suppliers currently have a genuine customer willing to sign enormous long-duration contracts. They still lack a deep pool of customers behaving at anything close to Microsoft's scale.
There is some encouraging diversification lately. Climeworks Solutions signed 14 new partnerships covering about 450,000 tonnes during the first half of 2026 across banking, aviation, healthcare, retail, luxury, technology and other sectors. The business now works with more than 200 companies.
Yet 450,000 tonnes across 14 new partnerships also shows the size of the gap. Microsoft signed 45 million tonnes in one fiscal year.
Forward carbon-removal offtake is already a working market-creation model. Calling carbon removal a mature standalone market would go too far.
| Carbon-removal evidence | Scale | Our read |
|---|---|---|
| Total 2025 offtakes | ~64 Mt | Commercial demand more than doubled |
| Durable 2025 removals | ~29 Mt | Higher-priced durable technologies are getting real contracts |
| Estimated contracted market value | ~$8B | Carbon removal has moved beyond pilots |
| Microsoft FY2025 contracts | 45 Mt with 21 suppliers | One buyer is driving a huge share of demand |
| Climeworks Solutions new 2026 partnerships | ~450,000 tonnes across 14 deals | Buyer diversity is improving, although volumes remain much smaller |

Can industrial climate tech scale through licensing instead of building factories?
Licensing can be a powerful climate tech business model when the technology plugs into infrastructure customers already own, although the company usually needs more than patents to create a large business.
CarbonCure is a good example of what the attractive version looks like. Its CO2-mineralization equipment is added to existing concrete plants. Producers can reduce cement use while maintaining required strength, which gives them a direct cost reason to adopt the system.
The deployment has become substantial. CarbonCure's producer network passed 10 million truckloads of concrete, representing more than 83 million cubic yards across hundreds of plants. More than two million of those truckloads were produced during the year before the milestone.
CarbonCure also adds a second revenue mechanism. Verified carbon credits are generated from the reductions and removals, and part of the credit revenue is shared with concrete producers. The company said producers had already received about $7.5 million through that revenue-sharing model.
So the customer can benefit from lower cement use, a lower-carbon product and carbon-credit revenue while continuing to operate an existing concrete plant. CarbonCure avoids having to finance the concrete factory itself.
LanzaTech shows why licensing can still take years to become economically powerful. The company licenses technology that converts waste carbon into fuels and chemicals, yet its full-year 2025 revenue was only $55.8 million against a $49 million net loss and a $71.3 million adjusted EBITDA loss. A large part of its recent licensing growth came from LanzaJet sublicensing activity, while engineering, research and product sales still contribute meaningful revenue.
That is common in industrial climate tech. Before hundreds of licensed plants exist, the company often earns money from engineering work, equipment, project development and strategic agreements.
The strongest licensing model has four things going for it at once: existing customer infrastructure, a measurable operating benefit, low disruption during installation and recurring economics as the technology gets used more.
Carbon credits can improve that equation. They are much more convincing here as extra revenue layered onto a useful industrial product than as the sole reason the customer adopts the technology.

Is battery recycling finally a good climate tech business?
Battery recycling is becoming a much stronger climate tech business, although the best model now looks broader than simply charging customers to process old batteries.
Redwood Materials is building around the entire battery lifecycle. In 2025, its Nevada operations produced about 60,000 tonnes of critical minerals including nickel, cobalt, lithium and copper. Redwood also makes battery materials, works with automakers on collection and has expanded aggressively into stationary energy storage.
Toyota's relationship with Redwood captures the circular logic. Toyota sends end-of-life batteries into Redwood's recycling system and has agreed to source cathode active material and anode copper foil from Redwood. General Motors has since become the first automaker to partner with Redwood across the full battery lifecycle.
Redwood has added another monetization route through Redwood Energy. Instead of immediately recycling every usable battery, the company can redeploy some packs into stationary storage. It expanded that business during 2026, including partnerships involving Rivian batteries and AI-infrastructure company Crusoe.
Investors appear to value that broader strategy. Redwood's latest Series E ultimately closed at $425 million after being increased from $350 million.
Li-Cycle gives us a useful comparison. Li-Cycle built an ambitious network of battery-processing facilities and then ran into a severe financing problem. The company suspended operations at some plants, entered court-supervised restructuring in 2025 and was eventually acquired by Glencore.
The contrast does not prove that Redwood's economics are already excellent; Redwood remains private and does not publish the financial detail we would want for that claim. It does show that recycling capacity by itself is a fragile model.
The stronger structure today is to control several points where value can be captured: battery collection, mineral recovery, battery-material production, second-life storage and long-term relationships with the companies that produce or need batteries.
Which climate tech business models are failing most often right now?
The climate tech models struggling most today usually combine heavy upfront capital, uncertain future customers and weak control over pricing.
Green hydrogen is an obvious example. While total energy-transition investment reached a new record in 2025, BloombergNEF measured only about $7.3 billion of hydrogen investment and found that the sector declined during the year. The gap between huge announced pipelines and projects that actually reach financing remains substantial.
The problem is straightforward. A green-hydrogen developer may need to finance an electrolyzer, renewable power, grid connections, storage and transport before it can produce anything. If buyers are still deciding whether they will pay more for low-carbon hydrogen, the developer ends up carrying both construction risk and demand risk.
Clean-tech manufacturing has another problem: overcapacity. BloombergNEF estimates that $127 billion went into clean-energy supply chains in 2025 and says excess capacity continues to pressure prices across batteries, solar and other technologies. Its latest trade research found the same pattern, with Chinese overinvestment compressing margins across clean-tech manufacturing even while product volumes grow.
Standalone hardware can suffer for similar reasons. ChargePoint's networked charging equipment produces very thin gross margins. Fluence recently combined a record backlog with a 5.1% quarterly gross margin. Demand can be real while suppliers fight so aggressively that customers capture most of the economic benefit.
Factory-first recycling has already produced a high-profile warning through Li-Cycle. Carbon removal faces a different vulnerability: buyer concentration remains extreme even after several years of rapid market growth.
Across all of these cases, the most dangerous setup is surprisingly consistent. The company spends hundreds of millions before securing reliable demand and expects future customers to absorb a green premium large enough to make the economics work.
Climate technologies with a real cost, reliability or supply-security advantage have a much easier path. That's the uncomfortable part of the market right now.

So what climate tech business models are actually working today?
The climate tech business models working best today are contracted infrastructure, hardware with recurring software or service, energy-as-a-service, operational energy software, financed customer subscriptions and industrial technologies that plug into assets customers already own.
The evidence across very different markets keeps pointing in the same direction.
Battery storage works because grids and power users need flexibility and costs are falling quickly. Kraken works because utilities rely on its software to run core operations. Ameresco earns most of its EBITDA from recurring activities even though projects still produce most of its revenue. Sunrun converts expensive household energy equipment into long-term payments and then finances those payment streams through the capital markets. Fervo uses long-duration electricity contracts to make geothermal projects financeable. CarbonCure fits into concrete plants that already exist and gives producers several ways to earn back the cost. Redwood is trying to extract multiple rounds of value from the same battery.
The strongest companies also change the source of their capital as they mature. Venture equity funds technology development and early commercialization. Later projects increasingly rely on project debt, securitizations, tax credits, infrastructure investors, customer contracts or other cheaper capital. That transition can matter as much as the underlying technology.
Lifetime monetization shows up again and again. Hardware gets better when software keeps earning. A construction project gets better when the company operates the asset afterward. A battery gets more valuable when it can serve a second life before recycling. Industrial technology gets stronger when a customer saves money and the climate benefit creates an extra revenue stream.
There is no universal climate tech business model to copy. There is, however, a very clear economic pattern.
The businesses doing best today generally solve a problem customers already care about: cheaper power, more available power, lower operating costs, grid reliability, access to critical materials, regulatory compliance or avoiding a large upfront investment. Decarbonization makes the proposition stronger.
The weaker models still need customers to care about carbon enough to rescue otherwise unattractive economics.
| Climate tech business model | Verdict today | Why customers pay | Main risk |
|---|---|---|---|
| Contracted infrastructure + project finance | Strong | Power, capacity, reliability and long-term supply | Construction and execution |
| Hardware + recurring software/service | Strong | Equipment plus ongoing control, optimization or support | Hardware-margin pressure |
| Energy-as-a-service / asset ownership | Strong | Savings and infrastructure without full upfront capex | Financing costs |
| Operational energy software | Strong | Core billing, control and utility workflows | Long enterprise sales cycles |
| Solar and battery subscriptions | Working | Lower upfront cost, lower bills and backup power | Capital costs and customer acquisition |
| Industrial retrofit + licensing | Working selectively | Lower production costs plus lower emissions | Slow industrial adoption |
| Integrated battery recycling | Promising | Critical materials, second-life batteries and supply security | Commodity prices and execution |
| Long-term carbon-removal offtake | Real but immature | Corporate carbon-removal commitments | Buyer concentration |
| Standalone low-margin hardware | Difficult | One-time equipment purchase | Competition strips out margin |
| Merchant green-premium production | Weakest | Customer willingness to pay extra for lower carbon | Demand may never justify the capex |
OUR METHODOLOGY
There is no single metric that tells us whether a climate tech business model is genuinely working. Revenue can grow while margins collapse. Demand can be real while a company remains dependent on expensive equity. A large market can exist without producing attractive businesses.
We therefore break the question into the economic dimensions that matter most: why customers pay, whether the company can capture value from that demand, how durable the revenue is, how deployment is financed, and whether the model becomes stronger as it scales.
For each dimension, we use the most recent signals available, prioritizing operating results, customer commitments, deployment data, margins, recurring revenue, financing transactions and market-level investment trends. Company filings and disclosures carry the company-level evidence; first-hand or leading institutional research provides the broader market context.
We do not treat every signal equally. A large pipeline shows interest; a binding contract says more about actual demand. Revenue demonstrates sales; margins show how much economic value remains with the supplier. An equity raise provides capital; non-recourse project debt or securitization shows that outside investors are prepared to underwrite the cash flows of the underlying assets.
We also combine company-level evidence with market-level evidence. A strong company does not automatically prove that an entire business model works, and a rapidly growing market does not guarantee attractive supplier economics. The final verdicts are our synthesis of those signals rather than mechanical scores.
The objective is to replace a question often answered through intuition with a structured aggregation of current commercial evidence. That is why the analysis separates demand, economics and financing instead of treating any single metric as decisive.
