PEM electrolyzers
Transforming industrial processes with green hydrogen
Replace fossil-derived hydrogen and fuels with green hydrogen to advance industries on their path to decarbonization.
The challenge: Decarbonizing heavy industries
Industries like steel, cement, chemicals, and glass are among the largest contributors to global CO₂ emissions. These sectors rely on high-temperature processes and fossil-based feedstocks, making them difficult to electrify and decarbonize. Customers need clean, scalable alternatives that integrate with existing infrastructure.
Our solution: Produce green hydrogen using PEM electrolysis
PEM electrolyzer systems produce green hydrogen using renewable energy sources — offering a drop-in replacement for gray hydrogen and fossil fuels. Green hydrogen is zero emissions and can support combustion, chemical synthesis, and reduction processes across a wide range of industrial applications.
Key advantages:
- Enables direct replacement of fossil-based hydrogen
- Supports high-temperature and high-purity operations
- Modular and scalable for pilot to full-scale deployment
Why green hydrogen in hard-to-abate sectors?
Green hydrogen offers industrial customers a practical path to deep decarbonization. Produced via PEM electrolysis, it delivers the energy intensity, purity, and flexibility needed to replace fossil-based inputs without compromising performance or productivity.

11 industries that benefit from cleaner hydrogen
Green hydrogen is a key enabler for decarbonizing hard-to-abate industrial sectors. Its versatility allows it to serve a wide range of applications. And while project sizes vary depending on hydrogen demand, each one comes with positive sustainability impacts.
How it works | Impact | |
---|---|---|
Refineries | Refineries use hydrogen in processes like hydrotreating and hydrocracking to remove sulfur and other impurities from crude oil, producing cleaner fuels such as diesel and gasoline. Currently, most hydrogen is produced via steam methane reforming, which is carbon-intensive. | Replacing conventional hydrogen with green hydrogen significantly reduces the carbon footprint of refining operations, especially in hydrotreating, supporting cleaner fuel production. |
Fertilizers | The fertilizer industry relies on the Haber-Bosch process to produce ammonia by combining hydrogen and nitrogen under high temperature and pressure. This process consumes 3–5% of global natural gas and 2% of final energy consumption. | Green hydrogen enables carbon-neutral ammonia production, reducing reliance on fossil fuels and supporting sustainable agriculture and food security. |
Chemicals | Hydrogen is a key reactant and building block in the chemical industry, used to produce ammonia, methanol, polymers, plastics, and for purification processes. | Transitioning to green hydrogen decarbonizes a wide range of chemical products, lowers greenhouse gas emissions, and reduces vulnerability to fossil fuel price volatility and supply chain disruptions. |
Steel | Traditional steelmaking uses coal in blast furnaces, emitting ~2 tons of CO₂ per ton of steel. The industry is shifting to direct reduction of iron (DRI), where hydrogen replaces coal as the reducing agent. | Green hydrogen-based steelmaking emits only water vapor, offering near-zero emissions and the potential to revolutionize one of the most carbon-intensive industries globally. |
Aluminum | Aluminum production involves refining bauxite into alumina and smelting it into aluminum, both requiring high heat. Hydrogen is used in annealing, calcination, and heat treatment, including recycling processes. | Green hydrogen supports low-carbon aluminum production and recycling, contributing to a circular economy and reducing emissions from high-temperature processes. |
Electronics | Semiconductor manufacturing requires ultra-clean environments and high-purity hydrogen as a carrier gas for thin-film deposition, etching, and stabilization. | On-site electrolysis provides a continuous supply of electronics-grade green hydrogen, ensuring product quality and process integrity while eliminating emissions. |
Cement | Cement production involves firing kilns at extreme temperatures using coal and petcoke. Additionally, limestone calcination contributes to 60% of the sector’s CO₂ emissions. | Green hydrogen can replace fossil fuels in kilns and be combined with captured CO₂ to produce e-fuels, enabling a circular carbon economy and reducing emissions in one of the most polluting sectors. |
Ceramics | Ceramics are fired in kilns at temperatures over 1,000°C to produce construction materials, sanitaryware, and technical ceramics. These kilns typically run on natural gas. | Switching to green hydrogen combustion lowers carbon emissions, supporting cleaner manufacturing of ceramic products. |
Oils + fats | Hydrogenation modifies the chemical structure of oils and fats for use in food, cosmetics, and biofuels, such as hardening oils for margarine. | Green hydrogen enables sustainable hydrogenation processes across the oils and fats value chain, reducing environmental impact in food and cosmetic production. |
Liquid hydrogen | Hydrogen is liquefied by cooling it to -253°C, making it dense for efficient transport and storage. It’s used in hydrogen-powered vehicles and aerospace propulsion systems. | When produced from renewable sources, liquid hydrogen supports zero-emission fuel supply chains for transportation and space exploration, enabling clean energy at scale. |
Tube trailer distribution | Hydrogen is distributed to industrial users via pipelines, tube trailers, or high-pressure cylinders. On-site electrolysis paired with strategically located filling stations creates localized production hubs. | Powered by solar or wind, this model reduces transportation costs and delivery times while establishing zero-emission supply networks for dispersed industrial customers. |
