Producing high-purity hydrogen from the blades of decommissioned wind turbines is a most ingenious idea. If this can be scaled up successfully, it would solve a number of challenges in one fell swoop: For one thing, it would save the effort of shredding, recycling or otherwise disposing of old blades. Instead their composite material could be usefully reclaimed. Secondly, it would open up an additional hydrogen source to help satisfy the rapidly rising demand for hydrogen. And thirdly, the process would result in an extremely clean form of carbon dioxide that could be used in various branches of industry. But before any of that is possible, a whole range of issues must first be overcome.
