There is also the risk that "low-carbon" hydrogen projects could end up siphoning renewable energy that would have been built anyway for the grid. It is therefore critical to ensure that low-carbon hydrogen procures electricity from "additional" renewables, especially when hydrogen production is supported by public subsidies.
