Elcogen funding rounds
| Date | Stage | Investors | Raised | Deal Summary |
|---|---|---|---|---|
| Jan 2025 | Series A | SmartCap (lead) | $6M | Elcogen is a leading European manufacturer of solid oxide technology, including solid oxide fuel cells (SOFC) and solid oxide electrolyser cells (SOEC), enabling efficient, affordable green hydrogen production and emission-free electricity. The company, with over 25 years of expertise, focuses on scaling production to meet global clean energy demands, supported by Estonian-Finnish R&D and global exports. Elcogen secured a €5 million investment from SmartCap, an Estonian state-owned venture capital fund supporting greentech companies, announced around January 2025. SmartCap led the round as the first scale-up investment in its Green Fund portfolio, complementing prior strategic investments from Baker Hughes and HD Hyundai. The funds aim to accelerate growth, scale operations, production capacity, and business development, particularly supporting construction of a new factory in Tallinn. This investment aligns with Elcogen's expansion milestones, including a €24.9 million EU Innovation Fund grant in late 2024 for gigawatt-scale production and the opening of the 14,000 m² ELCO I facility in September 2025, increasing capacity from 10 MW to 360 MW with approximately €50 million in capital expenditure funded by stakeholders. |
| Apr 2024 | Strategic investment | Baker Hughes (lead) | $33M | Elcogen, an Estonian manufacturer of solid oxide technology for efficient green hydrogen production via solid oxide electrolyser cells (SOEC) and emission-free electricity generation through solid oxide fuel cells (SOFC), closed a funding round totaling over €140 million. This package includes strategic equity investments from Baker Hughes, Hydrogen One Capital Growth plc (€24 million in 2022), HD Hyundai (€45-55 million in 2023), and Mirae (combined ~€31 million with Baker Hughes), plus over €24 million in European Commission project grants including an IPCEI project, and a proposed €15 million debt facility. Baker Hughes acted as a lead strategic investor, with funds allocated to scale manufacturing capacity, including a new 360MW factory in Tallinn, Estonia, and ongoing R&D for SOEC-based green hydrogen solutions. The Baker Hughes investment, announced around early 2024, builds on prior commitments and fosters collaboration with Elcogen and HD Hyundai on green hydrogen production systems. It serves as a validation of Elcogen's technology leadership in solid oxide stacks, targeting decarbonization for heavy industries pursuing net-zero goals. Hydrogen One Capital Growth, holding an 18.4% NAV stake in Elcogen, highlighted the endorsement from major energy players like Baker Hughes and HD Hyundai. The focus remains on expanding production to meet rising demand amid the energy transition, with Elcogen providing cells rather than complete systems for clean power, electrolysis, and related applications. |
| Oct 2023 | Strategic investment | Korea Shipbuilding & Offshore Engineering (lead) | $48M | Elcogen is an Estonia-based manufacturer of core components and stacks for solid oxide fuel cells (SOFC) and solid oxide electrolysers (SOEC), enabling efficient green hydrogen production and emission-free electricity generation from fuels like hydrogen, natural gas, ammonia, methanol, and biofuel. The company, founded in 2001, is recognized for its advanced technology with high energy efficiency, suitability for ship engines and cogeneration, and operation at high temperatures (600-1000°C). In October 2023, Korea Shipbuilding & Offshore Engineering (KSOE), part of HD Hyundai Group, signed a strategic €45 million (approximately $47.6-48 million or 64 billion KRW) investment in Elcogen, pending shareholder approval for new share issuance. This followed an MOU signed in January 2023 and extensive technology testing by HD Hyundai. The investment supports Elcogen's expansion of manufacturing capacity, including a new factory in Tallinn, Estonia, targeting up to 360 MW output to meet rising demand. It deepens collaboration between Elcogen and KSOE/HD Hyundai on designing, prototyping, and manufacturing large-capacity SOFC systems for marine propulsion (initially auxiliary power, scaling to full propulsion), stationary power generation, and green hydrogen production, with joint manufacturing planned in South Korea. HD Hyundai selected Elcogen's technology after market evaluation, viewing it as the most advanced SOFC available and key to its 'Ocean Transformation' strategy for decarbonizing maritime transport and achieving carbon neutrality. Elcogen's leadership, including Chairman Chris Nash and founder Enn Ounpuu, highlighted the investment as validation of their proprietary Solid Oxide technology's role in net-zero goals for heavy industries like shipping. HD Hyundai CEO Kisun Chung emphasized it as a cornerstone for a sustainable energy ecosystem, building on prior clean energy investments like $30 million in TerraPower in 2022. |
| May 2022 | Undisclosed stage | HydrogenOne Capital (lead) | $24M | Elcogen is a Tallinn, Estonia-based manufacturer of solid oxide fuel cell (SOFC) and solid oxide electrolyser cell (SOEC) technology, enabling efficient production of green hydrogen and emission-free electricity from hydrogen. The company serves over 60 industrial customers worldwide with reversible ceramic technology applicable to residential, industrial, and commercial uses. On May 9, 2022, HydrogenOne Capital Growth plc invested €24 million (£20 million) in Elcogen, acquiring a minority equity stake and board seat rights. Co-investors include Biofuel OÜ and VNTM Powerfund II. The funds supported expansion of facilities in Tallinn for automated production lines initially at 25MW/year capacity for fuel cells, scalable to 50MW/year or 100-200MW in electrolysis mode, plus R&D advancement. This investment advanced Elcogen's strategy to scale production, grow its customer base, and drive net-zero goals by making green hydrogen affordable. CEO Enn Õunpuu highlighted its role in developing cutting-edge technology and increasing revenues. HydrogenOne, launched in 2021, targets hydrogen-focused assets for capital growth. By September 2024, HydrogenOne's stake was valued at £23 million, representing 18% of its NAV, with a minor additional £1.4 million follow-on by end-2022 bringing total to £20.5 million. Elcogen continued raising capital post-2022, including €45 million from HD Hyundai in 2023, strategic investments from Baker Hughes, €5 million from SmartCap, and over €24 million in EU grants like IPCEI and Innovation Fund, totaling more than €140 million. These funds built a 360MW factory in Tallinn. Production is set to surge in 2025, leveraging 25+ years of expertise in solid oxide cells for energy security and fossil fuel transition. |
