What H2Electro does
H2Electro is an Estonian deep-tech company, founded in 2021 and headquartered at the Tartu Science Park, that manufactures high-temperature solid oxide electrolysis cells (SOECs) and stacks for green hydrogen production. Its core technology centers on all-ceramic fuel electrodes that replace conventional nickel cermet (Ni-YSZ) materials and operate at 800-850°C, enabling steam electrolysis and co-electrolysis of water and CO2 into hydrogen and syngas. According to the company, the design delivers approximately 30% higher electrical efficiency than traditional electrolysis, tolerates sulphur and carbon contaminants, and eliminates the need for precious metal catalysts such as platinum or iridium. The company is a subsidiary of Thule Capital AS and maintains a long-term research partnership with the University of Tartu's Institute of Chemistry that supplies its underlying materials-science expertise.
H2Electro operates a B2B enterprise sales motion targeting heavy industry (steel, ammonia, chemicals), energy utilities and renewable energy producers, and the synthetic-fuels value chain. Pricing is not publicly disclosed; the website uses "Request a Quote" CTAs indicative of multi-year, custom-priced contracts. As of the available data, the company has transitioned from laboratory testing to pilot/demo production of cells and stacks but discloses no commercial production capacity, revenue, or installed base. Its only named enterprise partner is Enefit Solutions, with whom it is co-developing a high-temperature co-electrolyser under EU Just Transition Fund backing in Estonia's Ida-Viru region. Complementary technology and channel partners include Dynelectro (Denmark, AC:DC mode control), Eltronic PTX (Denmark, Power-to-X process engineering), the Estonian national export agency EAS, and various Estonian research and cleantech associations.
The company has been primarily funded through non-dilutive public grants rather than venture capital: a €1.7 million state grant (June 2023), a €200,279.80 grant from the Recovery and Resilience Facility (November 2024), and €1,642,928.46 from the EU Just Transition Fund via the Estonian Enterprise and Innovation Foundation (January 2025), totaling approximately €3.5 million. It has been recognized as a Hello Tomorrow Deep Tech Pioneer (2023) and Product of the Year for Tartu and Tartumaa (2024). Leadership comprises CEO and co-founder Henrik Hal, CTO Silver Sepp (PhD, chemistry), COO Dmitri Opalnikov, and CFO Pille Vaheoja (joined June 2024); the team is reported in the 1-10 employee range.
