The Regulatory Assistance Project is beginning a new chapter of growth and thought leadership as we continue bringing clarity to the complexity of the clean energy transition. After thoughtful discussions between Richard Sedano and the RAP board of directors, Sedano… View Summary +
Register Now A 24/7 carbon-free electricity transition tariff is a tool to accelerate decarbonization generally while addressing times and places on the grid where emissions have been most difficult to reduce. 24/7 transition tariffs are different from… View Summary +
Policymakers across the globe are searching for solutions to reduce the use of fossil fuels and their associated climate impacts. Attention has focused on the heating sector, which relies heavily on fossil fuels and was responsible for almost 40% of… View Summary +
Thanks to an increase in manufacturing development, electricity demand is rising faster than expected in the Southeast. As a result, Duke, Georgia Power and TVA are asking their regulators to approve a series of new gas-fired generators using reliability and… View Summary +
(A summary version of this paper is also available.) An increasing number of national, state and local government leaders recognize that rapidly decarbonizing the electricity grid is necessary to slow the disruptive effects of a changing climate. At the… View Summary +
Heat pumps — all-electric, super-efficient temperature control appliances that can both heat and cool indoor spaces — are a key to decarbonizing heating, especially as the grid is served increasingly by carbon-free resources. The 2022 Inflation Reduction Act (IRA), the… View Summary +
Energizing Change Reflecting on the past year, I am struck by many reasons for hope amid the growing climate crisis. You will notice I have signed this as Co-Founder and Interim CEO. Before you dig into the exciting… View Summary +

The Regulatory Energy Transition Accelerator (RETA, https://retatheaccelerator.org/), launched at COP26, is an initiative to build capacity for energy regulators as they work to advance toward a clean energy transition. Serving as a resource hub for regulators, RETA’s flagship project,… View Summary +
建筑领域绿色低碳转型是中国实现双碳目标的重要战略举措,在碳达峰碳中和“1+N”政策体系下,住房城乡建设部在2022年3月印发的《“十四五”建筑节能与绿色建筑发展规划》明确了“提高建筑能效水平,优化建筑用能结构”的基本原则,更提出了“推动零碳建筑”和“近零能耗建筑”的项目试点。应用高能效供热系统是降低建筑总体能耗的一主要方式。放眼世界,很多设有“净零碳”排放目标的国家也已经开始计划并实行各种建筑供暖脱碳策略。电能热泵供暖(下面简称“热泵供暖”)和氢能锅炉燃烧绿氢供暖(下面简称“绿氢供暖”)便是正在被各国考虑和讨论的供暖主要路径的两种选择。 热泵供暖是国内比较熟悉的取暖方式,而绿氢供暖虽然小众,但其讨论热度却在逐渐上升。当前,欧洲一些地区正在尝试采用绿氢供暖。对于绿氢供暖的成本效益和可行性进行深入讨论已成为热点议题,尤其在英国,应该推荐哪种技术作为主要供暖方式、其余方式又该提供多少政府扶助等相关争论在英国已经推进了一段时间。本文参考英国的相关研究和讨论,对热泵和绿氢采暖的能效性、经济性和可行性进行了对比和分析,并从中总结了两个可能会对其它设有净零碳目标的国家具有参考意义的观点: 热泵具有更高的能源利用效率,并且有助于减污降碳协同、建筑电气化,与电力系统清洁转型等工作推进。 热泵供暖的总系统成本较之绿氢供暖更低,能降低社会在供热转型上的经济负担。… View Summary +
