Gas plays an enormous role in the UK energy system. It heats our homes, cooks our food and helps create the electricity that we use every day.

But the UK’s gas network is also responsible for 35% of the country’s total greenhouse gas emissions, meaning decarbonisation is essential if the UK is to meet its current ambitious climate target of net zero emissions by 2050.

Decarbonising it will be a major undertaking, necessitating changes to the UK gas network on a scale not experienced since gas first arrived in homes more than 60 years ago.

Hydrogen offers potential as a zero or low carbon energy source alternative. This is because when hydrogen is burned it doesn’t produce carbon dioxide (CO₂), only water and heat.
