The impact of 100% electrification of domestic heat in Great Britain.

Britain has been a global leader in reducing emissions, but little progress has been made on heat, which accounts for almost one-third of UK emissions and the largest single share is domestic heat, which is responsible for 17% of the national total. Given the UK's 2050 "Net-Zero" commitment, decarbonizing heat is becoming urgent and currently one of the main pathways involves its electrification. Here, we present a spatially explicit optimization model that investigates the implications of electrifying domestic heat on the operation of the power sector.

Assessing the impact of carbon dioxide removal on the power system.

Carbon dioxide removal (CDR) will be essential to meet the net zero targets that are integral to meeting the terms of the Paris Agreement. However, their co-deployment will have a substantial impact on the broader energy system, with BECCS providing energy services and DACCS consuming them. Thus, in this contribution, we present a framework for the co-optimization of the power and CDR sectors and apply it to the United Kingdom as a case study.

CO mitigation or removal: The optimal uses of biomass in energy system decarbonization.

Owing to its versatility, biomass can be used for a range of CO mitigation and removal options. The recent adoption of end-of-century temperature targets at the global scale, along with mid-century economy-wide net zero emission targets in Europe, has boosted demand forecasts for this valuable resource. Given the limited nature of sustainable biomass supply, it is important to understand most efficient uses of biomass, both in terms of avoided CO emissions (.
