"Blue" hydrogen: environmentalists urging gov't to drop funding

The ongoing debate over replacing natural gas with hydrogen for heating continues. Whilst oil and gas firms are pushing for the use of hydrogen when the country starts to phase out gas as a heating fuel, an article from the BBC explains that climate think tank E3G, WWF, and Greenpeace have sent a letter to the Business Secretary Kwasi Kwarteng urging the government to drop funding for "blue" hydrogen. Environmentalists state that heat pumps are a much better option. The article outlines the differences between "blue" and "green" hydrogen, and the views of those on either side of the argument.

Here are some interesting pages on the subject:
The World of Hydrogen has an information page on hydrogen and how it is made here.
E3G released a series of factsheets which you can find here.
