Shell and others are calling it "deep water energy". This is good PR, nothing more. They aren't going to base their revenue on charging cars; and they get carbon credits to look good.

If you search "BP global warming", the first 7 of 9 results are linked to BP.com about how they're taking action on climate change.

In February of this year, "BP dials back climate pledge amid soaring oil profits. The British oil giant wants to decrease its carbon emissions by between 20 and 30 percent by 2030. It previously aimed for a 35 to 40%." :

Says they are installing them at their gas stations. Probably a lot of money to be made from getting people to stop to charge and buy sodas etc.

Doubtful. It makes sense for oil companies to begin (though realistically continue) investing in alternative energies if they want to survive beyond this century due to the continued decreased cost of alternative fuel/energy sources.

Do they use an oil based generator to power the lights in the convenience store or the payment processors?

They will get the ev credits and they will be able to offset the production of fossil fuel.

BP were actually doing a lot of solar cell research from the early 1970s
