How hydrogen is transforming these tiny Scottish islands

Scotland’s Orkney Islands produce more clean energy than their inhabitants can use. Their next step? Hydrogen.

Hydrogen is not free of problems: it degrades metal, leaks above a very low level have the potential to negate the environmental benefits, and it's not particularly efficient because of the cost of compression. And Green hydrogen (which is more like a battery than a fuel) risks providing Big Carbon with a new excuse to pollute with their multi-coloured array of non-Green hydrogens (which are filthy fuels, nothing like a battery).

But I'm not at all convinced about nuclear providing better answers than renewables. It takes decades for a new nuclear plant to come online, the same money invested in renewables starts yielding benefits immediately. And the problem of disposing of nuclear waste is not yet solved.
