Cavendish Hydrogen A/S

Their core work

Cavendish Hydrogen (formerly H2Logic) is a Danish SME that designs and builds hydrogen refuelling stations and advanced hydrogen compression systems. Their core work centers on making hydrogen refuelling faster, more energy-efficient, and suitable for both passenger and heavy-duty vehicles. They develop hybrid compressor technologies — combining metal hydride and mechanical compression — to improve the economics and reliability of decentralised hydrogen infrastructure. Their equipment supports the rollout of hydrogen mobility networks across Europe.

What they specialise in

How they've shifted over time

In 2015–2017, Cavendish Hydrogen focused on hydrogen station network commercialisation, FCEV deployment economics (TCO, LCA), and grid balancing — essentially proving the business case for hydrogen mobility infrastructure. From 2019 onward, their focus shifted decisively toward hardware innovation: hybrid compressor development (metal hydride + diaphragm), energy efficiency improvements, and heavy-duty vehicle refuelling at multiple pressure levels. The COSMHYC series illustrates a textbook progression from research (2017) through scale-up (2019) to live demonstration (2021).

Moving from network-level deployment support toward proprietary compressor hardware for heavy-duty hydrogen refuelling — expect them to seek partners for industrial-scale and logistics applications next.

How they like to work

Cavendish Hydrogen operates overwhelmingly as a specialist partner (7 of 8 projects), contributing specific hardware and engineering expertise to larger consortia rather than leading them. Their one coordinator role (HyFast) was an SME Instrument grant — a company-focused format. With 106 unique partners across 14 countries, they maintain a broad European network, indicating they are well-connected and easy to integrate into new consortia as a technology provider.

Extensive network of 106 unique consortium partners spanning 14 countries, built through participation in major pan-European hydrogen mobility initiatives like H2ME. Their partnerships reflect strong ties to the FCH JU (Fuel Cells and Hydrogen Joint Undertaking) ecosystem.

What sets them apart

Cavendish Hydrogen occupies a rare niche: they are one of very few European SMEs with deep, demonstrated expertise in both hydrogen refuelling station engineering and advanced hybrid compressor technology. Their COSMHYC project series — running from fundamental research through to real-world demonstration — gives them a technology maturity that most competitors in this space lack. For consortium builders, they bring proven hardware capability with a track record of delivering across eight FCH JU and H2020 projects.

Highlights from their portfolio

• H2ME 2
  Largest single EC contribution (EUR 5.3M) — a flagship pan-European hydrogen mobility demonstration involving FCEV fleets and grid balancing.
• COSMHYC DEMO
  Culmination of a three-project R&D-to-demonstration arc on hybrid compressors, validating their proprietary metal hydride + mechanical compression technology at scale.
• HyFast
  Their only coordinator role — an SME Instrument Phase 2 grant (EUR 2M) for fast hydrogen fueling, signalling strong company-level innovation capacity.
