SUMMARY
- Nernst Electric has raised €1.7 million (US$2 million) in Seed funding from Hatch Blue’s Blue Revolution Fund.
- The Irish startup is developing on-site oxygen generation technology for fish farms.
- Founded in 2023, Nernst Electric combines advanced electrochemistry, 3D printing, and industrial gas expertise.
The company is developing on-site oxygen generation technology for fish farms. Its solution helps fish farms produce their own oxygen improving fish health while making aquaculture operations more efficient and sustainable.
“Since Nernst joined our Accelerator Fund, their progress has been fast and convincing. The team came in with a manufacturing concept and have built it into a working system ready for its first aquaculture deployment. That kind of technical execution is impressive – and it is precisely why the Blue Revolution Fund is the right backer to take it further,” said Caitriona Kelleher, Managing Director of Early Stage Investments at Hatch Blue.
“For decades, the limitations of conventional on-site oxygen generation have held back productivity across industries including aquaculture, mining, metallurgy, and steelmaking. Our breakthrough reactor technology removes those barriers, enabling the most efficient oxygen production at any scale with near-zero maintenance and the industry’s lowest operating costs,” said Nick Farandos, CEO, Nernst Electric

“Aquaculture is generating commercially attractive innovation at pace, and the sector’s own fundamentals are strong. Much of that innovation also has reach well beyond it. Nernst is a clear example: the platform that solves critical oxygen supply for fish farms has industrial-scale application across heavy industry. That is exactly what gives the Blue Revolution Fund the conviction to back it,” said Carsten Krome, Managing Partner and co-founder, Hatch Blue.
Founded in 2023 by Nick Farandos and Chris Matson, Nernst Electric combines expertise in solid oxide electrochemistry, advanced 3D printing (additive manufacturing), and industrial gas technology to develop innovative oxygen generation systems.
The company is building a new generation of on-site oxygen production equipment that helps businesses generate oxygen more efficiently, reducing costs and improving sustainability.
Fish farms need a constant supply of oxygen to keep fish healthy and support their growth. Today, most fish farms either receive liquid oxygen delivered by trucks from large production facilities or use on-site oxygen generators. These methods can be expensive and difficult to manage, especially for fish farms located in remote coastal areas.
