Their core work

MAS S.A. is a Greek SME specializing in advanced energy and power technologies, with a strong focus on supercritical CO2 (sCO2) power cycles and turbomachinery. They contribute engineering expertise to demonstration projects that aim to improve efficiency in power generation and industrial waste heat recovery across sectors like cement, glass, and aluminum. Their work spans flexible power plant operation, power-to-X energy storage solutions, and alternative fuel combustion including hydrogen and ammonia.

What they specialise in

How they've shifted over time

MAS S.A. entered H2020 in 2020 with work on combined cycle power plant flexibility and alternative fuels (hydrogen, ammonia) through the FLEXnCONFU project. By 2021, their focus shifted decisively toward supercritical CO2 power cycles and turbomachinery, with both SOLARSCO2OL and CO2OLHEAT centering on sCO2 technology applied to solar energy and industrial waste heat. This progression shows a move from broad power plant flexibility toward a specialized niche in next-generation thermodynamic cycles for decarbonized heat-to-power conversion.

MAS S.A. is concentrating on sCO2 power cycle technology — expect them to pursue further demonstration and commercialization of compact, high-efficiency turbomachinery for industrial decarbonization.

How they like to work

MAS S.A. operates exclusively as a participant, never as a coordinator, which is typical for a specialized SME contributing targeted technical expertise to larger consortia. With 58 unique partners across 16 countries from just 3 projects, they work within large, diverse consortia — their average consortium size exceeds 19 partners. This suggests they are comfortable operating in complex multi-partner environments and can integrate their work with many different types of organizations.

Despite only 3 projects, MAS S.A. has built a broad network of 58 partners across 16 countries, indicating exposure to a wide range of European energy research and industrial actors. Their network is pan-European with no obvious geographic concentration beyond Greece.

What sets them apart

MAS S.A. occupies a focused niche at the intersection of sCO2 turbomachinery and industrial waste heat recovery — a combination that few SMEs offer. Their participation in both solar-driven and industry-driven sCO2 demonstrations gives them cross-application experience in this emerging technology. For consortium builders, they bring specialized Greek SME capability in advanced thermodynamic cycles with hands-on demonstration project experience.

Highlights from their portfolio

• FLEXnCONFU
  Largest funding share (EUR 449,954) and addresses the high-profile challenge of making combined cycle plants flexible through hydrogen and ammonia combustion.
• CO2OLHEAT
  Demonstration-level project applying sCO2 cycles to real industrial waste heat in cement, glass, and aluminum — closest to market application.
