BRUSSELS, March 16 (Reuters) - The European Commission will outline plans on Thursday for a hydrogen subsidy scheme that would make clean versions of the fuel more competitive with fossil fuel-based hydrogen, a draft document showed.

EU industries use about 8 million tonnes of hydrogen, but the vast majority of that is produced using gas in a process that emits planet-heating CO2. The EU wants to switch to CO2-free hydrogen produced from renewable electricity to cut industry emissions.
