How can hydrogen be compressed more efficiently—without moving parts and with minimal energy losses? In conversation with H2international, David Colmar, CEO of the French company Eifhytec, explains the principle of thermochemical compression. The technology replaces traditional mechanical compression and was awarded the hy-fcell Award 2025 in the category Products & Markets. Colmar explains how the process works and what advantages it can offer in the storage and transport of hydrogen.
