Capacitors have a long way to go before they can capture and hold for slow release the capacity the same size/weight an LTO cell can. Then they have to last as long as an LTO cell. If they can master those 2 tasks, then they need to n=make them as safe as an LTO cell and find a way to manufacture them at the same costing or better than the current LYP cells because LTO cells will be at around that pricing by then.
The hydrogen fuel cell is a brilliant breakthrough in technology, but making the hydrogen clean enough to not foul the membrane is very expensive and a long way off at the moment. The problem is in the transport, either as natural gas (methane) or ammonia otherwise the hydrogen molecules escape through the holding vessel walls. Burning it in a turbine is a much better option, the hydrogen mixes with the air and uses the oxygen to create a highly flammable yet self cooling flame front because the by product is water and that adds density to the exhaust increasing thrust that drives the turbine. Harness a generator and you have a self charging electric vehicle.
But why change a fuel we have a lot of through a complex separation process when we can burn the methane in the turbine. Gas turbines have been around for years, we even use them now as peaking generators as part of the grid. We already have the technology and the plants built to liquefy methane (LNG) and the vessels it can be contained in for transport. We already have the technology to turn hydrogen into methane by adding a carbon atom, so we can create methane using excess renewable energy and sea water or under ground salinified (not even spell checker or Google are sure how that is spelt) that is destroying crop growing area from the rising salt levels as the underground water table rises. The by-product would be many minerals and salts that also has a value, Sungro has already proven that market.
So we already have all the required technologies, why aren't we doing it now? I think NP hit the nail on the head "Progress is always restricted by those in denial of the unfolding reality, or to protect their vested interests"
Another great saying attributed to John K Galbrath but I don't think it is just restricted to conservatives
