The growth of the green hydrogen industry has been disappointing, even while wind-solar-battery has made leaps and bounds. In 2022 the International Energy Agency forecasted 80 GW of solar and wind serving green hydrogen production by 2027, but has now lowered this to 75 GW achieved in 2028 – even to make 11 million tons of hydrogen each year, which will be less than 10% of global consumption. If the problem is cost of production, then the question becomes where and when green electricity will be cheap enough to produce cost-effective hydrogen. “Where” is a simple question – desert regions such as western India, northern China, the Gulf states, which can deploy utility-scale solar and wind at below $500 per…
