Trend analysis: Catalysis & electrochemistry for decarbonization — where the value pools are (and who captures them)

The global market for catalysis and electrochemistry applied to decarbonization reached approximately $28 billion in 2025, with projections placing it above $65 billion by 2032. But these top-line numbers obscure a more nuanced picture: value creation in this space is unevenly distributed across the technology stack, and the players capturing the largest share of economic returns are not always the ones generating the most scientific breakthroughs. Understanding where the value pools actually sit, and who is positioned to capture them, is essential for founders, investors, and corporate strategists operating in European and global markets.

Why It Matters

Catalysis underpins roughly 90% of all chemical manufacturing processes, and the chemical industry accounts for approximately 5.8% of global greenhouse gas emissions. Electrochemistry, once confined to niche applications like chlor-alkali production, has expanded into green hydrogen generation, CO2 conversion, and direct electrification of industrial processes that traditionally relied on fossil fuel heat. The EU's Carbon Border Adjustment Mechanism (CBAM), which entered its transitional phase in October 2023 and will impose full financial adjustments from January 2026, creates a direct price signal that makes low-carbon chemical production economically advantageous rather than merely aspirational.

The Inflation Reduction Act in the United States offers production tax credits of up to $3 per kilogram for clean hydrogen, while the EU's REPowerEU plan targets 10 million tonnes of domestic renewable hydrogen production by 2030. These policy frameworks are redirecting billions of euros in capital allocation toward catalytic and electrochemical technologies. The European Green Deal Industrial Plan, announced in February 2023, earmarked over 250 billion euros in public and private funds for clean technology manufacturing, with advanced catalysis and electrochemistry explicitly identified as strategic value chains.

For founders in the EU market, the timing is significant. The window for establishing competitive positions in catalyst manufacturing, membrane technology, and electrolyzer components is narrowing as incumbents accelerate their own transition strategies.

Key Concepts

Heterogeneous Catalysis for Emission Reduction involves solid-phase catalysts that accelerate gas or liquid-phase reactions critical to decarbonization. Applications include selective catalytic reduction (SCR) of nitrogen oxides, methane reforming with carbon capture, and Fischer-Tropsch synthesis for sustainable aviation fuel. The economics of heterogeneous catalysis are driven by catalyst longevity, selectivity (which determines feedstock efficiency), and the ability to operate at lower temperatures and pressures than uncatalyzed alternatives. Reducing operating temperature by 100 degrees Celsius can cut energy consumption by 15 to 25% in large-scale chemical processes.

Proton Exchange Membrane (PEM) Electrolysis splits water into hydrogen and oxygen using a solid polymer electrolyte membrane. PEM electrolyzers have gained market share over alkaline systems due to their ability to ramp quickly (reaching full output in seconds rather than minutes), making them compatible with variable renewable electricity supply. Capital costs have fallen from approximately $1,400 per kilowatt in 2020 to roughly $800 per kilowatt in 2025, with industry roadmaps targeting $400 per kilowatt by 2030.

CO2 Electrochemical Reduction converts captured carbon dioxide into valuable chemicals and fuels using electricity. Target products include carbon monoxide (for syngas), formic acid, ethylene, and ethanol. Faradaic efficiencies for CO production now routinely exceed 90% in laboratory settings, while multi-carbon products like ethylene remain below 70% efficiency. The technology's commercial viability depends on electricity cost, CO2 capture cost, and the market price of the target product.

Solid Oxide Electrolysis Cells (SOECs) operate at 700 to 850 degrees Celsius and achieve higher electrical efficiency than PEM or alkaline systems by using thermal energy to reduce the electricity required for water splitting. SOECs are particularly attractive for industrial settings where waste heat is available, such as steel mills, cement plants, and refineries.

Value Pool Map: Where the Economics Concentrate

Catalyst Materials and Manufacturing

The highest-margin segment in the catalysis value chain remains catalyst material development and production. Platinum group metals (PGMs) used in PEM electrolyzers and fuel cells represent a concentrated value pool: the global PGM catalyst market exceeded $15 billion in 2025. Johnson Matthey, BASF Catalysts, and Umicore dominate this space, with operating margins of 18 to 25% on specialty catalyst products. For startups, the opportunity lies not in competing on commodity PGM catalysts but in developing alternatives that reduce or eliminate precious metal dependency. Pajarito Powder, acquired by Hyzon Motors in 2023, demonstrated platinum loadings 80% below conventional benchmarks while maintaining comparable performance in fuel cell applications.

Electrolyzer Systems and Components

The electrolyzer market grew 40% year-over-year in 2024 to 2025, reaching approximately $5.2 billion globally. Value capture is bifurcating. System integrators like ITM Power, Nel ASA, and Plug Power compete on total cost of ownership and project delivery capability. However, the highest returns are accruing to component suppliers controlling proprietary technology: membrane manufacturers (Gore, Chemours, and Ionomr Innovations), electrode coating specialists, and bipolar plate producers. Ionomr Innovations, a Canadian startup, developed hydrocarbon-based PEM membranes that eliminate the need for perfluorinated materials, addressing both cost and environmental concerns. Their Series B round in 2024 valued the company at over $200 million.

Electrocatalyst Design for CO2 Conversion

Twelve (formerly Opus 12) has emerged as a leading player in CO2 electrochemical reduction, with partnerships including a deal with Mercedes-Benz to convert captured CO2 into precursors for automotive components. The company's electrolyzer technology converts CO2 and water into syngas, which can then be processed into fuels and chemicals. Twelve raised $645 million across multiple rounds through 2025. The value pool here is defined by the cost differential between fossil-derived and electrochemically produced chemicals. At current EU carbon prices of approximately 65 to 80 euros per tonne (as of early 2026), electrochemical CO2 conversion becomes competitive for high-value chemicals like carbon monoxide and formic acid, though not yet for bulk commodities like ethylene.

Balance of Plant and System Integration

While component technology commands attention, balance-of-plant engineering and system integration represent a substantial, though lower-margin, value pool. Power electronics, water treatment, gas purification, and control systems typically account for 40 to 55% of total electrolyzer system cost. Companies like Frames (acquired by Atlas Copco in 2023) and Hydrogenics (now part of Cummins) have built strong positions by offering turnkey integration services. EU-based integrators benefit from proximity to major project pipelines, including the European Hydrogen Backbone initiative targeting 28,000 kilometers of hydrogen pipeline infrastructure by 2030.

What's Working

Industrial Partnerships Accelerating Scale-Up

Haldor Topsoe (now Topsoe) exemplifies successful value capture through vertical integration. The Danish company manufactures both SOEC electrolyzers and the catalysts used in downstream hydrogen processing. Their partnership with First Ammonia to deliver a 100 MW green ammonia facility in Germany, announced in 2024, demonstrates the advantage of controlling multiple nodes in the value chain. By supplying both the electrolyzer and the ammonia synthesis catalyst, Topsoe captures value at two points rather than one, with combined margins estimated at 20 to 30% above single-product suppliers.

EU Regulatory Tailwinds Creating Demand Pull

The EU's delegated acts on renewable hydrogen, finalized in 2023, established strict additionality and temporal correlation requirements for hydrogen to qualify as "green." While these rules initially constrained project development, they have created a premium market for genuinely renewable hydrogen. Producers meeting the EU's criteria can access feed-in premiums of 1 to 3 euros per kilogram through national support schemes. This regulatory architecture favors European technology providers who understand compliance requirements and can embed certification into their system designs.

Membrane Innovation Reducing Costs

Evonik launched its Creavis division's anion exchange membrane (AEM) technology in 2024, targeting the cost gap between PEM and alkaline electrolysis. AEM systems use non-precious-metal catalysts and lower-cost membranes while approaching PEM-level power density. Enapter, an Italian-German company, has commercialized AEM electrolyzers at the kilowatt scale and is constructing a mass production facility in Saerbeck, Germany, targeting production costs 40% below current PEM systems by 2027.

What's Not Working

Scaling Laboratory Breakthroughs to Production

The "valley of death" between laboratory demonstration and commercial-scale manufacturing remains the dominant failure mode. CO2 electroreduction catalysts that achieve 90%+ selectivity at bench scale frequently degrade to 60 to 70% selectivity within weeks of continuous operation at pilot scale. Electrode fouling, membrane degradation, and thermal management challenges at scale introduce failure modes absent in controlled laboratory conditions. This gap has consumed multiple promising startups, including several EU-funded projects that delivered strong laboratory results but failed to demonstrate durable performance at the 100-kilowatt scale.

Precious Metal Dependency in PEM Systems

Despite years of research into platinum-free catalysts, commercial PEM electrolyzers still require 0.5 to 2 milligrams of platinum per square centimeter for cathode catalysts and 1 to 3 milligrams of iridium per square centimeter for anode catalysts. Iridium supply is particularly constrained, with global annual production of approximately 8 tonnes, almost entirely as a byproduct of platinum mining in South Africa. At projected electrolyzer deployment rates, iridium demand could exceed supply by 2028 unless loadings are reduced by 80% or alternative catalysts are commercialized.

Fragmented Standards and Certification

The absence of harmonized international standards for green hydrogen certification creates market friction. EU, US, and Asian definitions of "low-carbon hydrogen" differ in their treatment of grid electricity, temporal matching requirements, and lifecycle boundaries. This fragmentation increases compliance costs for technology providers serving multiple markets and delays investment decisions for project developers uncertain about which standard will prevail.

FAQ

Q: Where are the highest-margin opportunities in catalysis and electrochemistry for decarbonization? A: Catalyst materials and proprietary membrane technology command the highest margins, typically 18 to 30%, due to deep technical moats and high switching costs. System integration margins are lower (8 to 15%) but offer larger total addressable markets. Component suppliers with proprietary technology that reduces precious metal dependency represent the most attractive risk-adjusted opportunity.

Q: How does the EU regulatory environment affect value capture in this sector? A: EU policies including CBAM, the Renewable Energy Directive III, and national hydrogen strategies create both demand pull and compliance complexity. Companies that embed regulatory understanding into their product design, such as systems that automatically generate certification data for green hydrogen, can charge premium pricing and build customer lock-in.

Q: What is the realistic timeline for CO2 electrochemical reduction to reach commercial viability? A: For high-value products like carbon monoxide and formic acid, commercial viability exists today at EU carbon prices above 60 euros per tonne and electricity costs below 40 euros per megawatt-hour. Multi-carbon products like ethylene are 5 to 8 years from commercial viability at scale, primarily due to catalyst durability challenges and the need for electricity costs below 20 euros per megawatt-hour.

Q: Should founders focus on PEM, alkaline, SOEC, or AEM electrolyzer technology? A: The answer depends on target application and timeline. PEM dominates where rapid ramp capability matters (coupling with renewables). SOEC is optimal where industrial waste heat is available. AEM is the most promising for cost reduction but remains 2 to 4 years behind PEM in commercial maturity. Alkaline remains the lowest-cost option for steady-state baseload hydrogen production.

Q: What are the critical risks for startups in this space? A: The three primary risks are: (1) scaling failure when moving from laboratory to production, which has eliminated multiple well-funded startups; (2) material supply constraints, particularly for iridium and specialized membrane polymers; and (3) policy risk if carbon pricing or hydrogen subsidies are reduced or restructured before reaching profitability.
