Silent sailing, noisy generators: Hydrogen startups PowerUP and H2Boat tackle yachting's diesel problem

PowerUP Energy Technologies, the Estonian maker of hydrogen fuel cell generators, has struck a strategic partnership with Italian startup H2Boat. The target is yachts and other vessels that still rely on diesel when they need backup power or need to manoeuvre into harbour. The companies say they want to replace that compromise with an integrated, zero-emission setup.

H2Boat came out of the University of Genoa and brings marine hydrogen know-how plus metal hydride storage tech. That storage piece matters. Hydrogen is useful only if it can be handled safely and efficiently on a boat, where space and operating conditions are tight. H2Boat says its systems are built for onboard integration rather than bolted-on convenience.

PowerUP brings proton exchange membrane, or PEM, fuel cell generators into the mix. Together, the two companies say they can cover the whole chain: produce hydrogen from renewable electricity, store it on board, then turn it back into electricity when needed. The promise is less noise, no vibrations, and no greenhouse gas emissions from the power unit itself.

Dr Ivar Kruusenberg, PowerUP’s CEO and founder, framed the problem in blunt terms: the quiet of sailing gets wrecked the moment a diesel generator starts up. Thomas Lamberti, H2Boat’s CEO, said the partnership should make hydrogen feel less like a bundle of separate systems and more like one marine energy architecture. H2Boat is also working on local hydrogen production and refilling with maritime clients in the Ligurian area and near the Swiss-Italian border, which suggests this is about infrastructure as much as hardware.
