You can but there are concerns about hydrogen being a smaller molecule so we’d get increased leakage (with knock on effects)
No one really knows how our existing natural gas infrastructure will cope with hydrogen
- timthorn 4y agoTrials of grid distribution for up to 20% H2 blended gas have been undertaken successfully in the UK: https://hydeploy.co.uk/app/uploads/2018/02/HYDEPLOY-FOURTH-OFGEM-PPR.pdf https://hydeploy.co.uk/app/uploads/2018/02/HYDEPLOY-FOURTH-O... https://hydeploy.co.uk/app/uploads/2018/02/21935_CADENT_HYDEPLOY_REPORT_v3.pdf https://hydeploy.co.uk/app/uploads/2018/02/21935_CADENT_HYDE... https://academic.oup.com/ce/article/3/2/114/5487479 https://academic.oup.com/ce/article/3/2/114/5487479
- thomasmg 4y agoNatural gas infrastructure already deals with hydrogen: 2% of natural gas is hydrogen. For town gas which was used before (made from coal), hydrogen content was around 50%, so this isn't entirely new. Of course you can't re-use the existing infrastructure and use 100% hydrogen. This isn't black-and-white. Leakage is a disadvantage, as it is for fossil fuels (natural gas, oil, coal,...). Other technologies have other problems: windmills kill birds and bats! Pumped storage kills fish! Dams cause methane leaks! It is important to quantify how much of a problem those disadvantages really are.
