Hydros Power raises €250,000 to push hydrogen refrigeration toward approval
What's the deal? Alicante-based startup Hydros PowerDealroom has a profile for this one. Try Dealroom → has opened a €250,000 (≈$275,588) bridge round to fund regulatory approval of its STELION Powertrain for refrigerated transport, a hydrogen-powered system designed to replace diesel units that run transport refrigeration equipment.
What's the endgame? Founded in 2021, Hydros Power builds a modular green hydrogen ecosystem of interchangeable capsules, compact refuelling stations, and hybrid propulsion. It targets sectors where batteries fall short, such as logistics, urban mobility, and industrial transport.
Why now? The round lands at a transition point. After years of in-house development, the company has started series production of its STELION Booster Station, a hydrogen compression system, following CE and ATEX certification. It has confirmed orders and a pipeline of quotes covering more than 25 units.
Where the money goes: The funds are aimed chiefly at completing homologation and conformity procedures for the refrigeration system — a required step before commercial deployment. "This funding round will allow us to focus our efforts on a key approval milestone for our industrial growth," said chief executive officer Iván Navalón.
The round targets business angels, individual investors, and small funds, with a close expected before December 31, 2026. Hydros Power has previously attracted institutional backing, including from EIT Urban MobilityDealroom has a profile for this one. Try Dealroom →.
Separately, the company is developing plug-and-play storage through HyDDIM, a €1.05 million Eurostars project with Swiss partner New Generation TanksDealroom has a profile for this one.

What could go wrong? European hydrogen investment still faces high costs, uncertain long-term buyers, and uneven infrastructure, according to EU market monitoring. The real test is whether early orders and approvals turn into repeat customers.
The signal: This is a modest, practical step toward commercialisation rather than proof of broad demand. For deeptech hardware firms, clearing regulatory hurdles — not just building the product — is what unlocks the next stage of growth.
