Waaaaaay more than most deniers do! Any way you look at hydrogen production it takes a lot of energy including solar. I am all for Hydrogen energy over fossil fuels and agree with your thought about using existing gas stations. Also agree with your thoughts on placing PV panels in a land fill.

An organization known as Reclaim PV recently received development approval (DA) for a second recycling facility in Brisbane. Their first is in Lonsdale, South Australia.
“Securing this second DA marks another significant milestone for Reclaim PV in the establishment of Australia’s first national solar panel recovery and recycling network, with further facilities to be established in the other major metropolitan areas in the next one to two years,” said Clive Fleming, Director of Reclaim PV Recycling.
“We need a nationwide approach to managing the replacement and recycling of faulty, non-performing and end-of-life solar panels before this gets unmanageable and we start to see 2000 t of waste making its way to landfill annually.”

The Lotus Energy team.
Another business, Lotus Energy, is operating a solar module recycling plant that crushes and recycles 95 per cent of each cell, including all silica, glass, copper, aluminium and silver. The other five per cent — the plastic from the cable sheath and back box — is being tested for conversion to gas, oil and activated carbon.
Although it’s in its formative stages and requires further collaboration between industry, government and end-users to ensure a viable market and recycling infrastructure, a solution to the landfill problem is now in the works, Wilkins said.
