The energy crisis poses a devastating challenge for many this winter. Though the recent announcement of the Government's Energy Price Guarantee has taken a small step in the right direction by setting the typical household's bills at £2,500, there are many groups still at severe, potentially life-threatening risk. One such group includes those with a disability who will likely pay more than the average £2,500.
As fossil fuel-dependent industries such as heavy transport look towards cheaper low-carbon options to help them decarbonise, Regen's energy analyst Jonathan Lamont assesses the potential future role of one option being considered, e-Fuels', and their viability to help the UK transition to net zero energy.
