Why Hydrogen Has Failed Before β And Why This Time Is Different
Hydrogen has been “the fuel of the future” for at least five decades. The cynical reading is that it always will be. But something materially different is happening in 2025: the economics have finally shifted. Electrolyser costs have fallen 60% since 2020, renewable electricity prices have collapsed in prime solar and wind regions, and governments from the EU to India to Australia have committed hundreds of billions to hydrogen infrastructure.
Green vs Grey vs Blue: Understanding the Spectrum
Not all hydrogen is equal. Grey hydrogen β still 96% of global production β is made from natural gas via steam methane reforming, with significant COβ emissions. Blue hydrogen captures and stores those emissions (with variable effectiveness). Green hydrogen, produced by splitting water with renewable electricity, is the genuinely zero-carbon version. Its historical barrier has been cost. That barrier is crumbling.
The Industries That Will Transform First
Steel and cement are collectively responsible for 15% of global emissions and have no credible electrification pathway. Green hydrogen is their only realistic decarbonisation route. Industrial ammonia β the foundation of global food production through fertilisers β is another enormous opportunity. Together, these hard-to-abate sectors represent a market of several trillion dollars.
India’s Green Hydrogen Opportunity
India’s National Green Hydrogen Mission targets 5 million metric tonnes of annual production by 2030, leveraging its abundant solar resources. At full scale, analysts estimate India could become one of the world’s lowest-cost green hydrogen exporters, with production costs potentially reaching $1 per kilogram β below the threshold required for broad industrial competitiveness.
