Ecosystems, not isolation: an Estonian hydrogen firm joins Finland's H2 cluster
PowerUP Energy Technologies has been selected for Kasvu Open's Seed Village – H2 Fuel the Momentum programme in Central Finland, alongside VTT, ABB, Helen and two Jyväskylä universities. We look at why cluster infrastructure — not capital — is the binding constraint for Baltic hydrogen hardware, and what a Latvian version would need.

Great technology rarely scales on its own. It scales inside a cluster that already has the test rigs, the certification know-how and the industrial customers. That is the quiet story behind an Estonian hydrogen company taking a place in a Finnish accelerator this autumn.
An Estonian generator maker takes a seat in Central Finland
PowerUP Energy Technologies, the Tallinn-founded maker of hydrogen fuel cell generators, has been selected for Seed Village – H2 Fuel the Momentum, an RDI accelerator run by Kasvu Open with Jyväskylä Business Development Services under Finland’s Ecosystem Agreement. Ten to twelve companies get in per cohort.
The partner list is the interesting part: VTT, ABB, Helen, JAMK and the University of Jyväskylä — a national research institute, a global electrification vendor, a large utility and two universities around the same cohort. Selected companies get expert consultations, access to research facilities and pilot support. Worth noting: in the published list PowerUP appears with a Turku address, alongside Finnish firms. This is not a visit. It is membership.
Ecosystems, not lone innovators, move hydrogen hardware
PowerUP’s own framing was that innovations thrive in strong ecosystems. It sounds like a pleasantry. It is not. Hydrogen hardware has a specific problem: the technical risk is manageable, the validation burden is brutal. A generator destined for a telecom mast or a field hospital must prove cold-start behaviour, vibration tolerance, thermal signature, fuel logistics and compliance across jurisdictions before any procurement officer signs.
None of that is solved by a funding round. It is solved by test environments, standards expertise, and a utility or OEM willing to host a pilot where things can go wrong without ending the company. That is exactly what a structured accelerator holds. We’d flag this for Baltic hydrogen ecosystem stakeholders: the regional conversation is still framed around capital, but the binding constraint for a scale-up in Riga, Tallinn or Vilnius is usually a credible pilot host, not another term sheet.
The company at a glance
Founded in Estonia in 2016 by Ivar Kruusenberg, with engineering roots in European Space Agency hydrogen work.
Range spans roughly 400 W portable units to 20 kW mobile systems, with modular configurations for larger loads.
Applications: off-grid and backup power, telecom, defence and critical infrastructure — chosen for low noise, vibration and thermal signature.
Fuel cells are the part of the hydrogen economy already writing invoices
While still challenged by high costs and limited availability, green hydrogen is an increasingly viable route to decarbonising the awkward corners of the energy system — and portable power is the least awkward place to start. A 5 kW generator needs no pipeline, no eighteen-month offtake negotiation, no FID on a 100 MW electrolyser. It needs cylinders, a service network and a customer who values silence and zero local emissions.
That customer exists today: defence procurement, emergency services, remote telecom sites, construction under tightening urban emission rules. Small volumes against any national hydrogen strategy — but real revenue, real operating hours and real field data. The Baltic region writes its roadmaps top-down from gigawatt ambitions. The companies building durable businesses here are working bottom-up.
