Electricity is great for many things – gadgets, lighting, control systems, computers.
BUT in the UK we can't generate enough electricity to recharge lots of electric cars and to run lots of electric heating systems.
AND the UK National Grid at the moment can't deliver the power that is needed to keep the country running on totally green energy.
PLUS wind and solar energy supplies are very unreliable and storing electricity is VERY difficult. Large batteries are currently difficult to build, bulky and use toxic metals – plus once you plug a number of houses into a large battery, the charge doesn’t last long. Elon Musk has suggested a 30 MW battery to supply 30,000 homes in Australia – which sounds great until you realise the battery only supplies these houses for HALF AN HOUR
Firstly the UK needs to invest in a 'Smart Grid' where the electricity supply and demand is controlled and currents don't just flow in one direction from a power station to a customer.
Secondly the UK needs a better fuel to replace gas for our heating systems - this could be HYDROGEN.

Hydrogen can be used for heating and cooking:
Until 1960's the UK used Town Gas (half hydrogen) for its heating and cooking. We converted to Natural Gas (methane) when deposits of methane were discovered under the North Sea.
Each town in the UK is on a separate 'gas system' - because of the way that Town Gas was distributed. Converting each house in the UK to use hydrogen would be straight forward as it can be done town by town.
So we’ve converted everyone before!!!!

Hydrogen fuel cells generate electricity if fed with hydrogen (from a tank) and oxygen (from the air) and this electricity can drive vehicles.
Hydrogen gas is so light that, if there's a leak in a house, the hydrogen disperses quickly so can't create an explosion. And hydrogen fuel cell cars have Health and Safety experts checking their safety all the time.
