The UK Energy Research Centre (UKERC) released a paper on the policy implications of incumbency on the decarbonisation of the UK heat sector on Tuesday 15 May. The paper – the last of three working papers from the organisation’s Heat, Incumbency and Transformations project – highlighted lobbying and regulatory pressure, innovation and investment as three key areas where incumbent behaviour may affect the future of heat. The research also found that incumbents with an interest in gas envisaged a much greater role for gas-based heating in a low-carbon economy than those less involved. Interviews with non-incumbents however highlighted uncertainties converting the gas grid including costs, technical issues, expected carbon emission reductions and where the energy to produce the hydrogen would come from.
