EU policy projections on hydrogen possibly based on fundamentally incorrect economic projections.

It would appear these are at the overall project subsidization level, and we all know the costs projected in governmental procurement are almost always lowballed.

You see some technologies in the energy space where there is widespread adoption and rapid learning: photovoltaics, lithium batteries, and hydrofracking are examples.

The normal case is that unrealistically low cost estimates persist in the literature for years unchallenged and there is little adoption: green hydrogen, new nuclear, anything involving pyrolysis are a few examples.
