>Hydrogen production isn't efficient compared to grid transport and battery/hydro storage Electrolytic hydrogen production and consumption is not efficient. Mostly because of the consumption end of the equation (~50%, fuel-cell) rather than the production (~70-80%, electrolysis). But nuclear-driven thermochemical hydrogen production is currently being developed, and can theoretically exceed the thermal->electric conversion efficiency of the nuclear power plant: https://www.sciencedirect.com/science/article/pii/S0959652620338786 https://www.sciencedirect.com/science/article/pii/S095965262... https://www.sciencedirect.com/science/article/pii/S0360319922043555 https://www.sciencedirect.com/science/article/pii/S036031992... For applications where energy is used for incineration, direct chemical use of hydrogen, or when power-to-weight efficiency is critical, it has some potential: we are really comparing thermal->electric->thermal with thermal->hydrogen->thermal in that case. Such applications account for a decent fraction of total energy use. >campaign by oil/gas/nuclear Oil and gas companies have always worked against nuclear. There's no association there.
