Actually much of my experience is in the energy sector, and R&D is at the root of the
scientific method, with the difference being you are trying to solve a real problem vs describing
a natural event.
The physics does not change with the application, we have a sustainable energy problem,
and the current best batteries lack several attributes to allow them to replace the energy we get from fossil fuels.
Energy density,
wikipedia energy density
Gasoline 12,888.9 Wh/kg
Lithium-ion battery 100.00–243.06 Wh/kg
Even counting a bad Carnot efficiency for IC engines (20%) gasoline still has 2,577.78 Wh/kg, over
ten times the energy density as the best batteries.
BTW the best hybrids have an efficiency of 40% so can extract 5,156 Wh/kg from gasoline.
I am not saying someone will not come up with a battery that will solve all the problems,
but it is a very steep hill to climb.
In the meantime carbon neutral fuels would put energy sustainability AND by default net zero CO2 emissions within our grasp.
Battery electric cars, will not!
