The end of life carbon emissions are higher for hydrogen than BEVs currently on a mixed grid, and they still would be higher on a renewable grid, but the grid would need to be even bigger with hydrogen because of how inefficient hydrogen is from electricity generation to vehicle motion. When we move to sodium sulfur batteries, the emissions from battery production should drop significantly because sodium sulfur production will be greener, and the batteries will be much smaller. This is because the batteries are more energy dense, so they don't need to be as big, which means the cars will be lighter, and that also means the batteries won't need to be as big.
For hydrogen, to support desalination and electrolysis for hydrogen production, there would need to be massive infrastructure, and because hydrogen is far less efficient than BEVs, we would need to make far more renewable infrastructure for electricity generation, and then the gas stations would need to be converted to support hydrogen fuel, and that is far more expensive than putting up superchargers and plugging cars into the grid in a garage at home and work.
