ELI5: Explain Like I'm 5

Power-to-gas

Power-to-gas is like magic - it's a way to turn electricity we get from the sun or wind into a gas we can use in our homes and cars!

Imagine you have a shiny car and want to go for a drive, but you need some special juice to make the car go vroom. This juice is very important! Now, suppose you have a magic tool called an electrolyzer, that can take electricity and split water into two parts: hydrogen and oxygen. Hydrogen is like the special juice for your car!

So, using the electrolyzer, we get hydrogen from water and store it in a tank for later, until we need it to fuel our cars or heat our homes. But wait, there's more magic, because we can now also make methane or natural gas with the extra carbon dioxide in the air!

This process is called power-to-gas, and it's an amazing way to save energy, reduce pollution, and make use of renewable energy sources like solar and wind. Plus, it's good for the environment because we are recycling carbon dioxide instead of releasing it into the air. So, power-to-gas is like having a magical tool that can turn the sun's energy into a source of power that we can use every day!
