I think this "battery" should not return 50% of the energy supplied

80% Electrolysis 93% McPhy storage 60% heat pump and 95% efficiency of the electric car
Or 42%
For the accumulator 70% for charge-discharge and 95% efficiency of the electric car, i.e. 67%
The efficiency of the gasoline energy chain is around 10% ...
