Scottish utility fleet turns to hydrogen

[Think. Again.]

4. Converting any form of energy...

...to another form of energy does cost some of the original energy to do.

For instance... when charging an electric car battery, the charging station will "pump" more energy than the car battery will receive. The same with phone charging, or using radioactive material to heat water into steam for nuclear plant turbines.

When gasoline is burned to create the kinetic energy that moves a gas vehicle, energy is lost too.

So yes, any transfer of energy is gong to include a loss, and those losses will differ by what form of energy is transfered to what other form.

Luckily, the electrolysis can be run using non-CO2 sources of energy so no emissions are created from this "cost of doing business".
