Unlocking Green Oxygen's Potential for Planetary Carbon Management [PDF]
ChemSusChemWater electrolysis generates both H2 and O2, yet industrial focus remains largely restricted to H2‐driven reductions. The parallel use of O2 offers considerable rewards but remains underexplored. Unlocking this dual‐gas potential necessitates robust cross‐sector communication to identify and scale viable industrial use cases.
