| A good point. Depending on the latitude/weather/etc, the difference between winter PV production can see a reduction of between 40% and 85% compared to summer output (sampling from [0]). Panel prices have dropped so much, it's far more likely that, at least with places where summer output is double that of winter or less, that simply doubling the number of panels solves the problem. Batteries and PV are cheap and getting cheaper all the time, are proven and are absolutely trivial to install, operate and maintain compared to ANY conceivable process that involves hydrogen. I don't get the apparently insatiable drive/impulse that drives people to put so much effort into shoehorning hydrogen into the energy sector. It's expensive, inefficient, dangerous, leaky and is a potent greenhouse gas[1]. The hydrogen idea has been around for over 100 years, has never worked at scale, despite many efforts and large investments. It's time to walk away and concentrate effort into technologies that have actually delivered and have already reduced carbon emissions at scale.
