Hydrogen Production by Fossil Fuels
For hydrogen to have a significant impact on reducing greenhouse gas emissions, it will have to be manufactured in much larger volumes that it is at present. Currently, around 95% of global hydrogen production is generated from fossil fuels, primarily using natural gas and steam methane reforming. Conversion of fossil resources to hydrogen with CCUS is currently the most economic and practical means of bulk production of blue hydrogen.
In the UK, the Committee on Climate Change has recommended that significant volumes of low carbon blue hydrogen should be produced at in industrial clusters by 2030. Hydrogen will be produced for these clusters using natural gas either from nearby gas fields or from the national transmission system, and the resulting CO2 will be sequestered in neighbouring depleted reservoirs. Decarbonising these clusters will reduce UK emissions by 33 million tonnes of CO2 per annum by 2050.
