The solid-oxide electrolytic cells (SOEC) market is continuing to gain momentum with more moves in the space. Denso has signed a licensing agreement with UK-based Ceres Power to use its SOEC design. The collaboration’s specifics remain unclear, including whether Denso will integrate Ceres’ technology into existing designs or create new production lines. Earlier, Ceres was commissioned by Shell to design a 10 MW pressurized SOEC module aimed at achieving 30% more hydrogen production per kilowatt-hour compared to current low-temperature alkaline (ALK) or proton exchange membrane (PEM) electrolyzers. Lab tests show that Ceres’ SOECs are already 25% more efficient than alkaline or PEM electrolyzers when using external waste heat and electricity. The relevant question with SOECs is when, not if, which…
