Low-carbon hydrogen: hydrogen the energy content of which is derived from non-renewable sources which meets a greenhouse gas emission reduction threshold of 70%, with a full lifecycle assessment including all upstream emissions, indirect emissions and the CO2 capture and storage rate. Low-carbon gases: part of low-carbon fuels which mean recycled carbon fuels as defined in article 2 of Directive (EU) 2018/2001, low-carbon hydrogen and Synthetic gaseous and liquid fuels the energy content of which is derived from low-carbon hydrogen, which meet the greenhouse gas emission reduction threshold of 70%, with a full lifecycle assessment including all upstream emissions, indirect emissions and the end-of-life emissions to the atmosphere.
Our brief of the matter from June 2021 provides the reasoning for each of the above points and explains how the definitions provided here were deployed.
