Green hydrogen depends on massive oversupply of wind generation capacity during "peak wind" conditions (when the grid doesn't need wind generation, you use it to make H2 because the marginal price of the energy is close to zero). It's definitely a Good Thing, and probably the Next Big Thing for road transportation of goods (H2 is VERY high energy density by weight, better than diesel, but poor energy density by volume, so not suitable for cars or, um, aeroplanes)

SO... indeed, Ukraine never a player. Until they have massive eolian capacity on the Black Sea.
