Green hydrogen – produced using renewable energy – currently accounts for just 0.1% of global hydrogen production. But it''s a powerful bet for solving renewables'' intermittency problem and decarbonizing heavy industry. Scaling up green hydrogen does present challenges – but modern digital technology could provide some of the answers.
Generally, hydrogen is produced from renewable and non-renewable energy sources. However, production from non-renewable sources presently dominates the market due to intermittency and fluctuations inherent in renewable sources. Currently, over 95 % of H 2 production is from fossil fuels (i.e., grey H 2) via steam methane …
