Hydrogen fuel cells need air pumped into them to generate electricity, and the compressor doing that pumping can eat up to 40% of the energy the cell produces — like a car engine where the air conditioning eats almost half your fuel. Aeristech built a compressor that uses 10-20% less power than what's currently on the market, and it's up to 20% smaller too. Think of it as swapping a bulky, energy-hungry air pump for a compact, efficient one that lets fuel cell makers build smaller, cheaper systems. The project took this from a working prototype to demonstration-ready hardware aimed at high-volume manufacturing.
Hydrogen fuel cells are a leading clean energy technology, but they remain expensive. A major cost driver is the air compressor, which can consume up to 40% of the energy the fuel cell produces. Current compressors are too large, too power-hungry, and require frequent maintenance — all of which increase the total cost of ownership for fuel cell systems and slow down adoption in vehicles, backup power, and industrial applications.
Aeristech built and demonstrated an optimised air compressor for hydrogen fuel cells that uses 10-20% less power, is up to 20% smaller, and runs 4,000 hours without servicing. The project delivered a Compressor Demonstration Summary Report confirming the technology was tested using high-volume production techniques.
If you are a fuel cell manufacturer dealing with the high cost of balance-of-plant components and energy losses from air supply systems — this project developed a compressor that requires 10-20% less power than competitive products and is up to 20% smaller. That means your fuel cell stacks can be downsized and made cheaper without sacrificing output, directly improving your unit economics.
If you are a commercial vehicle maker integrating fuel cell drivetrains and struggling with packaging space and parasitic energy losses — this compressor runs 4,000 hours without servicing and is up to 20% smaller than alternatives. For fleet operators, that translates to less downtime and more usable cabin or cargo space in hydrogen-powered trucks and buses.
If you are a stationary power provider looking to cut operating costs for fuel cell installations — this compressor's 10-20% lower power consumption directly reduces the parasitic load on your system. With 4,000 hours of maintenance-free operation, it also cuts service visits for remote or hard-to-reach backup power sites.
The project does not disclose unit pricing. However, the objective states the compressor enables fuel cells to be made smaller and cheaper by supplying air at higher pressure more efficiently, with projected cumulative revenue of over €65 million by 2025 across their product line. Pricing details would need to come directly from Aeristech.
The entire purpose of this project was to move from prototype (TRL6) to production-ready samples manufactured using high-volume production techniques. A Compressor Demonstration Summary Report was delivered, confirming the technology was demonstrated. Aeristech is a single-company SME effort focused specifically on commercialisation.
Aeristech Limited is the sole consortium partner and likely holds all IP generated. As an SME instrument project with 100% industry participation and no university or research partners, licensing is straightforward — you would deal directly with one company. Specific patent details are not disclosed in the project data.
The objective states that FC-eCompressor requires 10-20% less power than competitive products, is up to 20% smaller, and runs continuously at high power for 4,000 hours without servicing. These three advantages — efficiency, size, and durability — are the key differentiators Aeristech claims over existing centrifugal and screw compressors.
The project objective mentions gaining approvals for commercial supply as a key goal. Based on available project data, the Compressor Demonstration Summary Report was completed, but specific certifications or regulatory clearances are not listed in the deliverables. Buyers should confirm current approval status with Aeristech directly.
The project ran from January 2020 to December 2021 and is now closed. The technology was at TRL6 at the start, with the goal of producing demonstration units using high-volume manufacturing techniques. Based on available project data, the demonstration was completed, meaning integration discussions could begin now with Aeristech.
This is a solo SME instrument project — Aeristech Limited from the UK is the only partner, with no universities or research institutes involved. That's actually a strong commercial signal: the EU funded a single private company to commercialise technology it already owns, meaning there are no complex IP-sharing agreements or academic partners to navigate. With 100% industry participation and SME status, Aeristech is positioned as a focused, agile supplier rather than a research consortium. The €817,530 EU contribution was targeted entirely at bridging the gap from prototype to production-ready product. For a potential buyer or integrator, this means one point of contact, one decision-maker, and technology that was built for market from the start.
