H2Electro is a deep-tech hydrogen startup using novel materials to develop cost-effective technologies, helping to achieve the goals of the green transition.
ABOUT US
H2Electro is a deep-tech start-up company that is developing and producing next-generation high-temperature electrolysers (HTEs) for the production of green hydrogen, enabling the replacement of fossil fuels with renewable energy. The novel approach originates from long-term research in the University of Tartu.
Together we are developing novel solid oxide cells which operate at 650 to 850 °C and could be applied in the electrolysis of water. High operating temperature helps to reduce electrical losses and thus increases the system efficiency. In HTEs it is possible to produce green hydrogen without using any precious metals in the electrolyser stack. Highly efficient HTEs for the production of hydrogen are a cornerstone of the future energy concept, helping to store energy and decarbonise large industries such as ammonia and steel production. Intermittent energy resources such as wind and solar could be used on a much larger scale than it is possible today. Fossil fuels like coal and natural gas could be replaced with renewable energy if efficient electrolysis was deployed on a large scale. In addition to the positive ecological impact, this technology would help to improve the energy security in the regions, where it is implemented.

Solid oxide electrolyser cells
The novel solid oxide electrolyser cells (SOECs) being developed by H2Electro are the next generation of power-to-x solutions. SOECs are electrochemical conversion devices that turn water and renewable energy into green hydrogen and pure oxygen. In addition to being able to split water into hydrogen and oxygen, SOECs are also capable of converting CO2 into CO and can even be operated in co-electrolysis mode, turning a mixture of H2O and CO2 directly into syngas (synthesis gas; H2 + CO). Our cells do not contain any precious metals or other rare elements, they are 100% ceramic, which lowers the cost of the cells and enables higher efficiency, stability, and robustness than our competitors’ products. Thanks to our cells being Nickel-free they are also more sulphur tolerant and can withstand much higher oxygen partial pressures. H2Electro’s SOECs are the most durable and efficient option for use in your electrolyser stack.
Solid oxide electrolyser stacks
SOECs can be connected in series to form SOEC stacks which are the most crucial part of a complete electrolyser system. H2Electro’s novel SOEC stacks consist of our own fully ceramic single cells and are designed to work at elevated temperatures (650 – 850 °C), leading to 30% higher efficiency than other electrolysis technologies. Waste heat from industrial processes like steel and fertiliser production can be used to heat the steam used in electrolysis which leads to electrical efficiencies of up to 100%. Fully ceramic materials have a much higher redox stability and impurity tolerance than Ni-cermets which are the current industry standard fuel electrode materials. This means that our stacks do not require a protective gas atmosphere or as thorough gas purification which significantly decreases the BOP costs of the electrolyser system. H2Electro’s SOEC stacks are the most cost-effective and robust option for electrolyser system manufacturers working to accelerate the green transition.
WHAT ARE WE DOING?
H2Electro develops the next generation electrolysers to produce green hydrogen.
The purpose of H2Electro is to provide an opportunity to enable widespread use of intermittent renewable energy sources (wind, solar), helping to reduce greenhouse gas emissions and air pollution. The next generation electrolyser, we are producing, works at high temperatures (650-850°C) and has the advantages of:
- 30% increased efficiency
- No reliance on precious metals
- The ability to utilize industrial waste heat to decrease electricity consumption
- Modular design for a range of electrolysis capacities
- Longer lifespan due to the use of advanced ceramic electrode materials
- The ability to produce syngas (H2 + CO) from H2O and CO2, which can be used as a precursor material for e-fuels
- Improved redox stability compared to traditional nickel ceramics
- A larger active surface area, allowing for the use of less electrode material at the same current density
- Higher resistance to sulphur poisoning and carbon deposition
We are manufacturing 1kW-5kW power stacks, which can be connected to meet the power needs of the customer.
AREAS OF USE
The electrolyser makes it possible to replace fossil fuels, such as natural gas, with renewable energy. The main uses of hydrogen are:
- Steel industry
- Production of fertilisers
- Fuel refining and synthetic fuels
- Energy storage
STEEL INDUSTRY
H2Electro electrolyser in green steel production
- By using the H2Electro system, the CO2 footprint of the steel industry can be reduced by up to 90%.
- Hydrogen can be used to eliminate the CO2 emissions in steel production.
- SOEC stacks have higher efficiency and lower footprint compared to low temperature electrolysers.
- Industrial waste heat can be used for the required thermal energy of SOEC stack operation.
- SOEC stacks with novel ceramic fuel electrodes are more resistant to various contaminants, so there is less need for gas purification.
- Simpler, cheaper and more efficient steel production can be achieved with H2Electro’s novel ceramic stacks.
