What CYRUS does

CYRUS S.A. is a Greek private company, founded in 2019 as a spin-off of NCSR DEMOKRITOS, that has developed a Metal Hydride Hydrogen Compressor (MHC) marketed as the MH-200-CYRUS-1.0. The system uses proprietary alloys free of Critical Raw Materials and a water-based heat-transfer loop at 10–85°C to compress hydrogen from low pressure to more than 200 bar, consuming only low-grade heat from solar thermal or industrial waste and producing no mechanical noise. This allows hydrogen refueling stations (HRS) to be sited in residential areas and reduces HRS OPEX by an estimated 85% relative to mechanical compressors, which currently account for roughly 50% of HRS capex and over 60% of O&M costs. The technology is patent-protected by the Hellenic Industrial Property Organisation (OBI), supported by a European patent application (protocol 28533/2023) and a Freedom-to-Operate report from Wuesthoff & Wuesthoff, and the product line is CE accredited.

CYRUS sells custom-designed compressor units directly to European hydrogen refueling station operators, clean-energy infrastructure developers, and government/municipal hydrogen programs via a B2B field-sales motion supplemented by trade-show participation (HYVOLUTION Paris, Thessaloniki International Fair) and EU funding-network visibility. The company's revenue model is hardware sales of compressor units under multi-year custom contracts, with pricing undisclosed publicly. Its first commercial deployment — the world's first thermal hydrogen compressor in an operational HRS — was inaugurated in 2024 at the NCSR DEMOKRITOS campus in Greece. To date the company has raised a pre-seed from Uni-fund, non-dilutive grants totaling approximately €600,000 (EIT Climate-KIC, EREYNO/Competitiveness & Entrepreneurship), and over €1 million in a 2024 equity round led by ADVENT Technologies alongside Uni-fund and other private investors. The 1–10 person team carries more than 100 person-years of hydrogen technology experience from European FP7 ATLAS projects, with leadership drawn from NCSR DEMOKRITOS, Mitsubishi Japan, and leading European technical universities.

Core offering

CYRUS designs, develops, and sells metal hydride hydrogen compressors (notably the MH-200-CYRUS-1.0 model) that compress hydrogen from approximately 5 bar to over 200 bar using water as a cooling/heating medium at low temperatures (10–85°C) and low-grade heat from renewable sources or industrial waste. The company offers standard and custom-designed compression systems primarily to hydrogen refueling station operators, clean energy infrastructure developers, and government-led decarbonization projects.

Product overview

CYRUS S.A. is a hydrogen technology company that offers a single flagship product line centered on its Metal Hydride Compressor technology. The core product is the MH-200-CYRUS-1.0, a noise-free hydrogen compression system that uses metal hydrides and water as a cooling/heating medium (10-85°C) to achieve pressures exceeding 200 bar, leveraging low-grade heat. The company has also deployed this compressor as a installed unit in Greece's first hydrogen refueling station (HRS) at NCSR Demokritos, marking the world's first thermal hydrogen compressor in a real operational HRS. Additional projects include the H2CYRUS R&D initiative for developing new metal alloys for hydrogen compression and the H2TRANS project for further scale-up and commercialization.
