Turbine giant Siemens Gamesa said it hopes to be producing cost-competitive green hydrogen from onshore wind by 2030 and offshore five years later, as a major research group said renewable H2 had seen a “paradigm shift” as governments and industry big-hitters pile into the sector.

Siemens Gamesa outlined a pathway to cost parity for green hydrogen produced using wind-powered electrolysis with the grey variety made using fossil fuels that currently dominates the market and is up to five times cheaper – if a series of policy and market conditions are met, and scale is achieved quickly.
