On the industrial side, hydrogen would be needed in large manufacturing units like steel plants and in power generation for the grid. Primary steel production needs chemical feedstocks like iron ore direct reduction which direct electrification does not provide. Similarly, batteries for solar power do not provide cost effective storage solution consistently for weeks and months making hydrogen a more suitable option.
Unlike electrification, where India is behind the curve especially with China that has cornered most of the resources, hydrogen also gives it the opportunity to be among the first movers worldwide. In an uncertain world where globalisation, as it was perceived earlier, is being revised this is of much significance. Plus, the fact that Reliance has taken the lead makes it that much more serious.
