While most hydrogen startups struggle with prohibitive production costs, Equatic has engineered a financial breakthrough by creating two revenue streams from a single process: carbon removal credits and green hydrogen sales. With $11.6 million in fresh Series A funding and construction underway on commercial facilities in Singapore and Quebec, investors must determine whether this dual-revenue model represents genuine innovation or clever financial engineering dependent on volatile carbon markets.
Seawater Alchemy Turns Ocean Chemistry Into Dual Revenue
On a concrete pad in Singapore, Equatic's pilot facility quietly performs what the company describes as a form of industrial alchemy. Seawater flows into an electrolyzer where renewable electricity splits it into hydrogen, oxygen, acid, and base. The resulting alkaline solution captures atmospheric CO2, which is then stored as solid carbonates and bicarbonate ions. From this single process emerge two distinct products: green hydrogen for energy markets and carbon removal credits for companies seeking to offset emissions.
This UCLA spinout claims its technology accelerates ocean carbon removal 99,000 times faster than natural processes, capturing approximately 4.6 kg of CO2 per cubic meter of seawater processed. The company states these carbonates remain stable for over 10,000 years, with solid forms potentially lasting "billions of years" – a claim that warrants scrutiny given the importance of permanence in carbon removal.
What distinguishes Equatic from other hydrogen producers is its dual revenue model. While conventional electrolysis produces only hydrogen, Equatic generates both hydrogen and carbon removal credits that can be sold to companies seeking to offset emissions. The company claims to "replace 40% of the energy used for carbon dioxide removal with the hydrogen produced," enhancing economic viability.
The carbon accounting behind these credits has received validation from two registries: Isometric and Puro.earth. Both adhere to ISO 14064-2:2019 standards, but this validation deserves scrutiny. Puro.earth was acquired by Nasdaq in 2021, raising questions about how verification standards might evolve as the carbon market expands. As carbon credit registries, both Isometric and Puro.earth have inherent interests in the growth of carbon markets they serve, which investors should consider when evaluating validation claims.
Yet a critical gap remains in the public record: specific performance metrics from pilot operations that would validate efficiency claims. Without this data, investors cannot independently verify whether the technology performs as claimed at scale or how production costs compare to conventional methods.
Following the Money - Can Carbon Credits Really Subsidize Hydrogen?
The fundamental economic challenge for green hydrogen is stark: production costs range from $3 to $7 per kilogram, compared to $1 to $2 for conventional "grey" hydrogen derived from natural gas. This cost differential has stymied widespread adoption despite hydrogen's potential as a clean energy carrier.
Equatic's innovation isn't technological – it's financial engineering. They're not dramatically reducing the $3-7/kg production costs; they're creating a parallel revenue stream from carbon credits that theoretically subsidizes hydrogen production. But the math doesn't work: at current average carbon prices of $4.8 per ton, a facility removing 3,650 tons of CO2 annually could theoretically generate only $17,520 in carbon credit revenue - though Equatic may be securing premium pricing for their technology-based credits.
Their model requires carbon prices to increase at least tenfold to become economically viable without subsidies, creating dangerous dependency on carbon market growth that contradicts recent price trends. The global voluntary carbon credit market was valued at approximately $1.4 billion in 2024, with prices falling 20% from 2023 levels.
Equatic's model requires substantial growth in carbon markets, which are projected to reach between $7 billion and $35 billion by 2030, potentially expanding to $250 billion by 2050. The company has secured a $30 million offtake agreement with Boeing for both carbon removal and hydrogen, demonstrating market interest but raising questions about price sustainability.
Equatic's public disclosures provide no specific figures on actual production costs per kilogram of hydrogen or per ton of carbon removed from pilot operations – precisely the figures investors need to validate their economic model. This selective disclosure pattern is common in early-stage cleantech: trumpeting technical achievements while providing limited financial metrics that would allow genuine due diligence. The absence of these specific figures should raise immediate red flags for potential investors.
From Lab to Market - Can Academics Execute Commercial Deployment?
Equatic's leadership team brings strong technical credentials but limited commercial experience to the challenging task of scaling a dual-market technology. Chief Technology Officer Gaurav Sant, named to TIME's 100 Most Influential Climate Leaders in 2024, has published over 200 peer-reviewed papers and secured support from prestigious organizations including the Department of Energy's ARPA-E program.
The technical challenges facing seawater electrolysis are substantial and well-documented in scientific literature. The chlorine evolution reaction competes with the desired oxygen evolution reaction, leading to decreased hydrogen output and accelerated electrode degradation. Chloride ions in seawater cause corrosion and degradation of electrodes, while insoluble substances like magnesium and calcium hydroxides can deposit on the cathode, blocking catalytic sites and impairing long-term performance.
Recent research shows some electrodes maintaining stable performance for over 800 hours under high current conditions, but Equatic hasn't disclosed degradation rates from their own operations. The company claims to address these challenges through oxygen-selective anodes developed with ARPA-E support, which supposedly eliminate unwanted chlorine production during seawater electrolysis.
Commercial scale-up plans are ambitious. The Singapore facility ("Equatic-1") is designed to remove 3,650 metric tons of CO2 annually while producing 105 metric tons of hydrogen. More ambitious is the Quebec facility, engineered to remove 109,500 tonnes of CO2 and produce 3,600 tonnes of green hydrogen annually.
What remains unclear is whether this academic-rooted team can successfully navigate the complex commercial landscape of carbon markets and hydrogen offtake agreements. The transition from laboratory success to commercial viability requires different skills than those evidenced in the team's academic publications.
Investor Due Diligence - Separating Promise from Peril
The glaring discrepancy between Equatic's public claims and their conspicuously missing financial data follows a familiar pattern I've documented repeatedly: cleantech startups that substitute technical jargon for verifiable economics.
For investors considering Equatic, rigorous due diligence should focus on three critical areas where public disclosures fall short of providing necessary verification.
First, carbon accounting methodology requires scrutiny beyond the ISO standard reference. Equatic claims its carbon removal process operates within a closed system, allowing for continuous and precise monitoring of CO2 removal. The company states it uses online sensors for real-time measurement of seawater chemistry and CO2 removal rates. However, independent verification of these measurements and their consistency with carbon credit issuance is essential for validating the primary revenue stream.
Second, electrolyzer durability in seawater environments represents a critical technical risk. Scientific literature clearly identifies chloride-induced degradation as a major challenge for seawater electrolysis. Standard electrolysis typically requires about 50 kWh of electricity to produce a kilogram of hydrogen, but Equatic hasn't disclosed their specific energy consumption figures. Investors should demand detailed performance data from pilot operations, including degradation rates, maintenance requirements, and component replacement schedules.
Third, contingency plans for carbon market volatility deserve close examination. With carbon credit prices falling 20% in the past year, Equatic's dual revenue model faces significant market risk. Investors should question what happens if carbon prices remain at current levels rather than rising to the projected figures needed to make the model viable.
Betting on Dual Markets
Equatic's approach represents a fascinating financial innovation in hydrogen economics – using carbon removal credits to effectively subsidize hydrogen production costs. For investors, the key question isn't just whether the technology works, but whether the dual revenue model can withstand market volatility and scaling challenges.
Investors should demand three specific disclosures before committing capital: independently verified production costs from pilot operations, degradation rates of seawater electrodes over 1,000+ hours of operation, and sensitivity analysis showing viability across various carbon price scenarios. The company's progress at commercial facilities in Singapore and Quebec over the next 12-18 months will provide crucial validation of both the technology and business model.
Equatic's carbon credit gambit may represent genuine innovation in hydrogen economics – or it may prove to be clever financial engineering that cannot withstand market realities. The answer lies in technical and financial details that remain hidden from public view, making thorough due diligence essential for potential investors.
