Climate-Tech and Clean Energy Startups: Insurance for Carbon Credits, Green Hydrogen, and Emerging Technologies

India's commitment to achieving 500 GW of non-fossil fuel capacity by 2030 and net-zero emissions by 2070 has catalysed a wave of climate-tech investment. The sector attracted over INR 12,000 crore in venture funding between 2023 and 2025, spanning solar manufacturing, green hydrogen production, carbon credit marketplaces, battery storage, waste-to-energy, and carbon capture technologies. The National Green Hydrogen Mission alone targets 5 million metric tonnes of annual green hydrogen production by 2030, with a government outlay of INR 19,744 crore.

Yet the insurance industry has not kept pace with these developments. Standard property and engineering insurance products, designed for conventional power generation and manufacturing, do not adequately cover the risks associated with emerging clean energy technologies. A green hydrogen electrolyser operates under different risk parameters than a conventional petrochemical plant. A carbon credit marketplace faces delivery and counterparty risks that no standard policy addresses. A direct air capture facility uses novel chemistry that underwriters have limited actuarial data to price.

The result is a protection gap that leaves climate-tech startups exposed to catastrophic losses at the very stage when a single major incident could end the company. A fire at a lithium-ion battery storage facility, a failure in a carbon credit delivery contract, or a catastrophic hydrogen leak during electrolysis can each generate losses running into tens of crores. Without adequate insurance, these losses fall on the startup's balance sheet, often wiping out equity and killing the venture.

This gap also affects the sector's ability to attract capital. Institutional investors, project finance lenders, and international development finance institutions (DFIs) typically require proof of adequate insurance as a condition of funding. If a climate-tech startup cannot demonstrate coverage for its key risk exposures, it may be shut out of the capital markets that it needs to scale.

This article examines the insurance challenges specific to Indian climate-tech startups, focusing on carbon credit delivery risk, green hydrogen production hazards, next-generation solar and wind technology risks, and the D&O and professional liability exposures that come with operating in a fast-changing regulatory environment. For each risk area, we identify the coverage gaps in standard products and outline the bespoke solutions that are emerging in the Indian and international markets.

India's carbon credit market is growing rapidly, driven by both the voluntary market (companies buying credits to meet ESG commitments) and the emerging compliance market under the Carbon Credit Trading Scheme (CCTS) notified by the Bureau of Energy Efficiency (BEE) under the Energy Conservation (Amendment) Act, 2022. Indian startups operate across this ecosystem as project developers (generating credits from renewable energy, afforestation, or methane capture projects), aggregators, verification bodies, and marketplace operators.

The primary insurance risk in carbon credit markets is delivery risk. A project developer sells forward credits based on projected carbon reductions. If the project underperforms, whether due to lower-than-expected solar irradiation, failure of a reforestation project due to drought, or technical issues with a methane capture system, the developer cannot deliver the contracted credits. The buyer may claim damages for the undelivered credits, the cost of purchasing replacement credits at prevailing market prices, and any penalties incurred under its own compliance obligations.

Standard commercial insurance does not cover this exposure. Property insurance covers physical damage to the project assets but not the consequential loss of carbon credit production. Business interruption insurance may cover lost revenue if triggered by an insured peril (such as fire or storm damage to a solar plant), but the carbon credit revenue stream is often not specifically scheduled in the policy, leading to coverage disputes.

The emerging solution is carbon credit delivery insurance, also called carbon performance insurance. This product, currently offered by a handful of international insurers including Swiss Re, Munich Re, and specialty Lloyd's syndicates, guarantees a minimum volume of carbon credit delivery. If the project delivers fewer credits than the insured threshold, the policy pays the difference at the contracted credit price. Annual premiums typically range from 3% to 8% of the insured carbon credit value, depending on the project type, location, and historical performance data.

Indian startups can access this cover through international brokers with London market placement capability. The challenge is that Indian carbon credit projects, particularly newer categories like biochar production or blue carbon (mangrove restoration), have limited performance data, making underwriting difficult. Companies should maintain detailed monitoring, reporting, and verification (MRV) records from day one, as this data is essential for obtaining competitive insurance terms.

A related exposure is verification and certification risk. If a third-party verifier (such as Verra or Gold Standard) revokes or downgrades a project's certification, previously issued credits may be invalidated. This risk is generally excluded from carbon credit delivery insurance and must be managed through contractual protections and due diligence rather than insurance.

Green hydrogen, produced by electrolysis of water using renewable electricity, is at the centre of India's clean energy strategy. The National Green Hydrogen Mission provides production-linked incentives and targets that have attracted major industrial groups (Reliance, Adani, NTPC, Indian Oil) and a cluster of startups focused on electrolyser manufacturing, hydrogen storage, and distribution infrastructure.

The risk profile of green hydrogen production is fundamentally different from conventional hydrogen production (grey hydrogen from steam methane reforming) and from other renewable energy generation. Hydrogen is highly flammable, with a wide explosive range (4-75% concentration in air), low ignition energy, and invisible flames. These properties create fire and explosion risks that are more severe than those in conventional chemical processing.

Engineering insurance products, specifically erection all risks (EAR) and machinery breakdown (MB) policies, provide the foundation of cover for green hydrogen facilities. EAR insurance covers losses during the construction and commissioning phase, including damage to the electrolyser stacks, balance-of-plant equipment, and associated infrastructure from fire, explosion, natural catastrophe, or construction defects. MB insurance covers operational-phase equipment failures, including electrolyser membrane degradation, compressor failures, and power supply anomalies.

The coverage gap arises from the technology performance risk. Proton Exchange Membrane (PEM) and Alkaline electrolysers have well-documented degradation curves, but newer technologies such as Solid Oxide Electrolysers (SOEC) and Anion Exchange Membrane (AEM) electrolysers have limited operational track records. Insurers are cautious about covering performance degradation beyond what is attributable to a sudden and accidental event, which means gradual efficiency loss, the most common failure mode for electrolysers, may fall outside standard MB cover.

Technology performance insurance, sometimes called output guarantee insurance or efficiency degradation cover, is available from specialist insurers. This product guarantees a minimum hydrogen production output or electrolyser efficiency level. If the equipment degrades faster than the insured degradation curve, the policy pays for the shortfall. Premiums depend on the technology type, manufacturer warranties, and operating conditions, typically ranging from 1.5% to 4% of the insured output value per annum.

Hydrogen storage and transportation add further layers of risk. High-pressure storage tanks (at 350-700 bar) and cryogenic liquid hydrogen storage require specialist property insurance with coverage for pressure vessel failure, boil-off losses, and contamination. Indian insurers such as New India Assurance and National Insurance Company have begun writing these covers, but they often require reinsurance support from international markets for larger facilities.

Startups should also consider environmental liability cover. A hydrogen leak, while not toxic, can cause secondary fire damage to surrounding areas. If the facility is located in an industrial zone and a fire spreads to neighbouring properties, the public liability and environmental cleanup costs can be substantial. The Public Liability Insurance Act, 1991, mandates cover for hazardous substance handlers, and hydrogen producers must verify whether their operations fall within the Act's definition.

While conventional solar PV and onshore wind projects have well-established insurance products and underwriting frameworks, the next generation of renewable energy technologies presents risks that stretch these products beyond their intended scope.

Bifacial and heterojunction (HJT) solar panels, floating solar installations, and building-integrated photovoltaics (BIPV) each carry technology-specific risks. Floating solar projects, for example, face risks from anchor failure, panel submersion, marine fouling, and water body level fluctuations that are not contemplated in standard solar property insurance. India's floating solar pipeline, including the 600 MW project at Omkareshwar Dam in Madhya Pradesh and the 100 MW project at Ramagundam in Telangana, requires specialist cover that addresses both the solar technology risk and the marine/lacustrine environment risk.

Offshore wind, which India is beginning to develop with the Ministry of New and Renewable Energy (MNRE) targeting 37 GW by 2030, introduces construction risks during offshore installation (vessel collision, subsea cable damage, monopile driving failures) and operational risks (turbine blade failure in extreme weather, foundation scour, marine growth) that are covered under marine and offshore energy insurance rather than standard engineering insurance. The premium rates for offshore wind construction in India are expected to be 1.5-3% of the total project value, significantly higher than the 0.3-0.5% typical for onshore wind.

Battery energy storage systems (BESS) represent perhaps the most challenging risk for insurers. Lithium-ion battery fires are difficult to extinguish, can reignite days after apparent suppression, and release toxic fumes. The total loss of a BESS facility can run into hundreds of crores. In 2024, a battery storage fire at a facility in South Korea caused damages exceeding USD 30 million and triggered a reassessment of BESS underwriting worldwide.

Indian BESS developers should expect rigorous underwriting requirements, including compliance with UL 9540A testing standards, National Fire Protection Association (NFPA) 855 guidelines (or equivalent Indian standards once published by BIS), and manufacturer-specific safety protocols. Property insurance premiums for BESS in India currently range from 0.8% to 2% of the insured value, depending on the battery chemistry, fire suppression systems installed, and the facility's proximity to other assets.

Technology performance insurance for battery degradation, covering the gradual loss of storage capacity beyond warranted levels, is available from specialist markets. This cover complements the manufacturer's warranty by providing financial compensation if the battery's state of health falls below guaranteed thresholds, which is particularly valuable for project finance lenders who need assurance that revenue projections will be met over the asset's 15-20 year life.

Climate-tech startups in India operate in a regulatory environment that is evolving rapidly. The Carbon Credit Trading Scheme rules are still being finalised. Green hydrogen certification standards are being developed by BEE and the Ministry of Petroleum. Renewable Purchase Obligations (RPOs) are being revised. The taxonomy for green bonds and sustainable finance is under discussion. Each regulatory change can alter a startup's business model, compliance obligations, and risk profile.

D&O insurance is essential in this environment. Directors of climate-tech companies face personal liability exposure from multiple sources. Investors who committed capital based on regulatory assumptions that later change may allege that the board failed to adequately disclose regulatory risk. Project finance lenders whose loans underperform because a subsidy was reduced or a tariff was renegotiated may bring claims against the directors. And regulators themselves may take enforcement action if the company's operations violate environmental clearances, safety standards, or emissions reporting requirements.

The D&O policy for a climate-tech startup should include coverage for securities claims (relevant for companies that have raised capital through SEBI-regulated instruments), regulatory investigation costs (covering inquiries by the Ministry of Environment, CERC, state electricity regulatory commissions, BEE, and pollution control boards), and employment practices claims (relevant for companies scaling rapidly and managing large workforces at project sites).

Professional liability is another significant exposure for climate-tech companies that provide advisory, verification, or consulting services. Carbon credit verifiers, sustainability consultants, and energy audit firms face claims if their assessments prove inaccurate. If a verifier certifies a carbon credit project that later turns out to have overstated its emission reductions, the buyers of those credits may bring professional negligence claims. Professional indemnity cover with limits appropriate to the potential claim size, typically INR 2 crore to INR 10 crore for mid-size advisory firms, is essential.

The policy wording for climate-tech D&O and professional indemnity should be reviewed for ESG-related exclusions. Some policies now exclude claims arising from greenwashing allegations, environmental misrepresentation, or failure to meet stated sustainability targets. For a climate-tech company, these exclusions could gut the policy's value. Companies should negotiate the removal of such exclusions or, at minimum, ensure they are narrowly drafted to apply only to intentional fraud rather than good-faith errors in environmental reporting.

Premiums for D&O insurance for Indian climate-tech startups range from INR 2 lakh to INR 8 lakh per annum for limits of INR 2 crore to INR 10 crore. Professional indemnity for climate advisory firms ranges from INR 1.5 lakh to INR 5 lakh for similar limits.

The insurance needs of a climate-tech startup evolve dramatically as the company moves from seed stage through growth and into project finance. A thoughtful insurance strategy should anticipate each phase and build coverage incrementally.

At seed and pre-Series A, the priority is protecting the founding team and the company's intellectual property. D&O insurance is essential from day one, particularly if the company has raised capital from angel investors or seed funds, as investor disputes are the most common D&O trigger at this stage. Professional indemnity may also be needed if the company is providing consulting or advisory services to generate revenue while developing its core technology. At this stage, a combined programme costing INR 3 lakh to INR 8 lakh per annum may suffice, covering D&O and PI with limits of INR 1 crore to INR 3 crore.

At Series A and B, as the company begins piloting its technology, engineering insurance becomes relevant. An EAR policy should be in place before construction or installation of any prototype or pilot facility. If the company is deploying equipment at third-party sites (for example, installing electrolysers at an industrial customer's facility), the contractual insurance requirements will typically mandate specific cover types and limits. The insurance budget at this stage typically grows to INR 10 lakh to INR 30 lakh per annum, adding EAR, MB, and potentially product liability if the company is selling equipment.

At the project finance stage, insurance requirements become highly specific and are typically dictated by the lender's independent insurance advisor. Project finance lenders require property all risks, MB, business interruption, third-party liability, environmental liability, and often construction all risks for the build phase. The insurance programme for a INR 500 crore green hydrogen project might cost INR 1.5 crore to INR 3 crore per annum in premiums, representing 0.3-0.6% of the project value.

Carbon credit delivery insurance should be considered as soon as the company enters into forward sale contracts for carbon credits. The cost of this cover, typically 3-8% of the insured credit value, should be factored into the company's carbon credit pricing model from the outset.

For companies operating across multiple technologies or geographies, a master insurance programme with local policies in each jurisdiction provides consistency of cover and administrative efficiency. Indian insurers can issue local policies that comply with Indian regulatory requirements while ceding risk to international reinsurers who have expertise in climate-tech underwriting.

A broker with both Indian market knowledge and international specialty market access is essential for climate-tech placements. The risk is too novel and too complex for standard retail insurance channels.

While the Indian climate-tech insurance market is still maturing, early claims experience and international loss data provide valuable indicators of the exposures that companies should prepare for.

In 2024, a solar-plus-storage project in Rajasthan suffered a lithium-ion battery fire that destroyed the entire BESS facility and damaged adjacent solar inverters. The total loss exceeded INR 45 crore. The property insurer covered the replacement cost of the solar equipment but disputed the BESS claim on the ground that the battery fire resulted from a manufacturing defect, which the insurer argued fell under the product liability exclusion in the property policy rather than the fire peril. The dispute, which took eight months to resolve, highlights the need for clear policy wording on whether internal battery fires are treated as fire losses or product defect losses under the property policy.

A carbon credit project developer in Maharashtra experienced a different type of loss. A methane capture project at a landfill site was validated and registered under Verra's Verified Carbon Standard. However, the project's actual methane capture rate was 40% lower than the projected rate due to unexpected waste composition changes. The developer had sold forward credits based on the projected rate and faced claims from buyers for non-delivery. Without carbon credit delivery insurance, the developer had to purchase replacement credits on the open market at a significantly higher price, resulting in a loss of approximately INR 3 crore.

Green hydrogen ventures have seen equipment-related claims. An electrolyser manufacturer's pilot facility in Gujarat experienced premature membrane degradation within 18 months of commissioning, resulting in a 30% drop in hydrogen output. The machinery breakdown insurer initially declined the claim on the basis that gradual degradation is not a sudden and accidental event. After negotiation and expert evidence demonstrating that the degradation rate was abnormal and attributable to a manufacturing defect in the membrane material, the claim was partially settled.

These examples illustrate recurring themes. First, the boundary between property insurance, product liability, and technology performance insurance is often contested, and policy wordings must be scrutinised before inception to minimise ambiguity. Second, carbon credit and revenue-related losses require dedicated cover rather than reliance on standard business interruption, which may not respond to non-physical loss triggers. Third, the claims process for climate-tech losses is often slower and more contentious than for conventional risks, because loss adjusters and surveyors may lack expertise in the specific technology, making it essential to identify specialist adjusters in advance.

Climate-tech founders should approach insurance not as a regulatory obligation but as an enabler of growth. Adequate insurance unlocks project finance, satisfies investor due diligence requirements, and provides the financial resilience to survive operational setbacks that are inevitable in a sector deploying unproven technologies.

The immediate priorities are as follows. First, secure D&O insurance before raising any external capital. Investors increasingly expect this as a baseline, and the cost at the seed stage is modest, typically INR 1.5 lakh to INR 3 lakh per annum.

Second, before commissioning any pilot or commercial facility, obtain engineering insurance (EAR for construction, MB for operations) with a policy wording that has been reviewed for technology-specific exclusions. Standard exclusions for gradual degradation, faulty design, and defective materials should be negotiated or replaced with limited exclusions that preserve cover for the consequential damage from these causes.

Third, if the business model involves carbon credit generation and sale, budget for carbon credit delivery insurance from the point of first forward sale. The premium cost should be built into the credit pricing model. Companies that wait until a buyer demands proof of delivery insurance will find themselves negotiating under time pressure.

Fourth, engage a specialist broker early. Climate-tech insurance placement requires market knowledge that generalist brokers do not possess. A broker with access to Lloyd's of London, European specialty markets, and Indian capacity can structure a programme that covers the full risk spectrum at competitive terms.

Fifth, maintain detailed engineering and performance data. Underwriters price novel technology risks based on data, and companies that can provide granular operational data, including efficiency metrics, maintenance records, failure mode analyses, and independent technical assessments, will obtain better terms than those that present only high-level project descriptions.

Sixth, participate in industry initiatives to develop standardised insurance products. IRDAI's sandbox framework allows insurers to test innovative products for emerging sectors. Climate-tech industry associations should work with IRDAI and Indian insurers to develop standardised wordings for green hydrogen, BESS, carbon credit delivery, and other climate-tech risks. Standardisation will reduce transaction costs, improve coverage consistency, and accelerate market development.

Finally, build a risk management culture that goes beyond insurance. Insurance transfers financial risk but does not prevent incidents. Investing in safety management systems, regular audits, employee training, and emergency response planning reduces both the likelihood and severity of losses, which in turn leads to lower insurance premiums and more favourable policy terms over time.
