The UK is committed to a reduction in carbon dioxide (CO2) emissions of 80% by 2050.
The majority of CO2 emissions come from using energy to heat our homes, keep industry turning, driving or simply boiling the kettle. There has been good progress on using renewable energy sources for electricity. But heat is responsible for around one third of overall UK CO2 emissions. 8/10 UK homes use gas to heat their homes because it is a convenient and reliable energy source.
Some ‘low carbon’ gases are already in use; such as biomethane, a renewable gas made from animal or food waste. But this type of gas cannot meet demand. Most of the gas used today is fossil fuel based natural gas. Fossil fuels release CO2 when they burn and their supply is limited. Further research is needed to understand other low carbon gas options.
Hydrogen: a low carbon gas?
Hydrogen offers potential as a zero or low carbon energy source. This is because when hydrogen is burned it doesn’t produce CO2, just water and heat. It could be used for a plentiful supply of low carbon energy for heat and transport.
HyDeploy is one of a number of research projects exploring how hydrogen could be used. It will be the first practical demonstration of customers using a blend of hydrogen and natural gas for everyday heating and cooking. The results of HyDeploy will tell us more about whether hydrogen is a good option to reduce CO2 emissions from heat in a way that is easy for UK customers.
