The object
Dan Sobek co-founded 1s1 Energy and co-developed boron-based proton-exchange membrane materials for water electrolyzers. The physical electrochemical cells reduce the electricity required to make hydrogen and are being piloted with industrial partners as a route to lower-cost green hydrogen.
What Dan did
Co-invented boron-based electrochemical membrane materials for more efficient hydrogen electrolyzers.
Why it matters
MIT reports partner tests in which electrolyzers using the membrane needed about 70% of the energy required by incumbent devices.
Living-status check
MIT’s April 2026 profile names Sobek as 1s1 Energy’s co-founder, quotes him on the technology’s current customer work, and documents active scale-up with a materials company.
