Caplyzer raises SEK 7M to cut green hydrogen costs with membrane-free electrolyzers
Stockholm-based Caplyzer has raised SEK 7 million (about $730,000) in a seed round to develop its technology for producing green hydrogen. Trio Impact Invest led the round, with Almi Invest joining as a co-investor.
Caplyzer is building membraneless electrolyzers, an alternative to conventional systems used to make green hydrogen. Traditional electrolyzers rely on expensive membranes that raise costs and complicate manufacturing.
By removing the membrane, the company aims to simplify system design, cut production costs, and improve scalability. The new capital will fund further technology development, validation, and the push toward commercialisation.
Green hydrogen is seen as a key part of the energy transition, especially for sectors that are hard to electrify, including heavy industry, chemicals, shipping, and steel. As demand grows, startups are racing to improve the efficiency and economics of electrolyzer technology.
The technology is unproven at scale. Caplyzer still needs to demonstrate that its membrane-free approach works commercially before it can compete on cost.
At $730,000, this is a small early bet — sitting near the bottom of the funding range for deals like it. But it reflects steady investor interest in Swedish ClimateTech and in breakthrough approaches to lowering the cost of clean hydrogen.
