Conversion has losses, true. For electricity to gas and back the losses are around 50%. That's perfectly fine for a technology you need for maybe a couple of weeks per year. The real question is how expensive the equipment is. Power is essentially free for renewables, all costs are depreciation of equipment. And as I said above, people _have_ implemented it already. There are dozens of MW of hydrolyzers installed in Germany alone.
