What NPROXX does

NPROXX is a private B2B manufacturer of Type 4 composite pressure vessels for high-pressure hydrogen storage, headquartered in Heerlen, Netherlands, with primary production in Alsdorf, Germany. The company was established in 2018 as a spin-off of Enrichment Technology Company and is jointly owned by ETC PV Holding and Powergroup International (50/50). Its engineers developed the world's first certified Type 4 pressure vessel in 2001, giving it a multi-decade pedigree in carbon-fibre-reinforced polymer (CFRP) engineering that underpins its current product portfolio across three pressure tiers: up to 500 bar for transport and stationary storage, 350 bar for buses and heavy-duty vehicles, and 700 bar for automotive.

The company produces both individual vessels and complete tank systems (including valves, brackets, and thermal-over-pressure safety devices), and notably scales to large 6-metre systems for rail and trucking. The AH620-70 (350L, 12.4 kg usable H2 at 700 bar) and AH710-70 (553L, 22.2 kg usable H2 at 700 bar) are flagship 2024 launches, both undergoing R134 and HGV2.0 certification. Reference customers include BMW Group (custom 700 bar vessel with proprietary fire-resistant coating for the iX5 Hydrogen), Siemens Mobility (Mireo hydrogen train), and Mobility & Innovation (hydrogen truck). Manufacturing takes place in a newly commissioned ~10,000 sqm automated facility in Alsdorf offering >30,000 tanks/year theoretical capacity.

NPROXX operates as a Tier 1/2 supplier selling directly to OEMs (automotive, bus, truck, rail, maritime) on a project-by-project negotiated basis, with demand generation supported by presence at major industry trade shows (IAA Transportation, Hydrogen Technology Expo Europe, InnoTrans, Hannover Messe). Revenue is derived from serial production contracts with vehicle manufacturers and hydrogen infrastructure operators; no public pricing is disclosed. Geographic expansion is planned via licensing arrangements in the US and China.

NPROXX supplied the centre-tunnel vessel (4 kg H2 capacity), developed a polyamide liner to BMW's specifications, and created a proprietary fire-resistant coating for enhanced fire safety. The vessel is among the first 700 bar tanks to meet the new R134 standard. BMW iX5 Hydrogen stores 6 kg H2 total (2 kg additional vessel under rear seat) enabling 500+ km range.
• Siemens MobilitycoreStrategic or Co-development PartnerNPROXX provided certified hydrogen storage vessels for the Siemens Mireo hydrogen train platform. The collaboration involved achieving vessel certification for rail applications. NPROXX has been certified for the Siemens hydrogen train project, demonstrating compliance with stringent rail safety requirements.
• Mobility & InnovationcoreStrategic or Co-development PartnerNPROXX established a partnership with Mobility & Innovation for a new hydrogen truck featuring NPROXX pressure cylinders on board. Announcement made in late 2024. The partnership involves integration of NPROXX's Type 4 pressure vessels into a hydrogen-powered truck platform.
• CumminsstrategicStrategic or Co-development PartnerNPROXX works in close partnership with parent company Cummins on hydrogen storage solutions for the heavy vehicle market. Cummins is a major global power and hydrogen technology provider. The relationship provides NPROXX with strategic access to the broader Cummins hydrogen ecosystem and customer base.
• H2Mobility (Germany)minorStrategic or Co-development PartnerNPROXX supports hydrogen infrastructure buildout by supplying storage vessels to companies like H2Mobility, which operates hydrogen refuelling stations in Germany. This is an indirect commercial relationship through the hydrogen ecosystem rather than a formal partnership agreement.
