[Episode #248] – The Future of Geothermal

Apr 23 2025

Although geothermal power plants have operated commercially in various parts of the world for decades, the sector hasn't attracted the investment needed to reduce costs and enable global deployment. But with further development, new methods of harnessing geothermal energy to produce heat and electricity could deliver as much as 800 GW of geothermal power capacity worldwide by 2050. That’s equivalent to the electricity demand of the United States and India combined.

In December 2024, the International Energy Agency (IEA) published "The Future of Geothermal Energy," a report exploring opportunities in this sector.

Our guest today is a lead author of that report. In this conversation, Heymi Bahar, Senior Renewable Energy Analyst with the IEA, discusses geothermal energy’s full technological potential and strategies for unlocking investment in this promising resource.

Guest:

Heymi Bahar is a Senior Renewable Energy Analyst with the International Energy Agency (IEA). Before IEA, Heymi worked as a trade policy analyst at the Organisation for Economic Co-operation and Development (OECD) where he analysed domestic inventive measures for renewable energy sources with possible trade implications. He also worked on cross-border trade in electricity and the development of renewables-based electric power. Heymi graduated from Sabanci University and holds a Master degree on Energy, Resources and Environment from the Paul H. Nitze School of Advanced International Studies of Johns Hopkins University.

[Episode #243] – Decarbonizing Heating

Feb 12 2025

Mini Episode

Heat pumps work almost like magic—delivering several times more heat energy than the electricity they require to run. Modern heat pumps are so efficient, they can even extract warmth from freezing temperatures, keeping buildings comfortable despite the cold outdoors.

With many policymakers seriously exploring ways they can accelerate heat pump adoption, we thought now is the perfect time to offer some specific and useful guidance on designing effective approaches for realizing this goal. Our guest today is Dr. Richard Lowes, a specialist in heating technology and policy with the Regulatory Assistance Project in Europe. He also co-chairs the Clean Heat Forum international policy network. Richard has advocated for heating policy since earning his doctorate in the subject from the University of Exeter a decade ago, advising the Scottish government’s heat decarbonization programme board, various UK parliamentary select committees, and serving in multiple roles within the UK government.

In this episode, we discuss why the energy transition requires us to fix leaky buildings, tradeoffs between energy efficiency upgrades and simply swapping out old boilers for heat pumps, the best policies to encourage heat pump adoption, and the measures available in Europe to support all these efforts.

Guest:

Dr. Richard Lowes is a specialist in the technology and policy associated with heating and is based within RAP’s Europe programme. He joined RAP in 2021 with over 10 years’ heat policy experience in industry, academia and working with policymakers. Richard currently coordinates much of RAP’s work on clean heating in Europe and globally, and as part of this, co-chairs the Clean Heat Forum international policy network.

After earning an advanced degree in energy policy, Lowes worked for UK energy company SSE before moving on to gas transporter SGN, where he led the company’s work on policy and public affairs. This was at a time when few were considering, let alone working on the issue of cleaning up heating. In 2014 he moved to the University of Exeter, where he completed a doctorate alongside various heat policy and regulation-focused research projects. He was particularly known for his analysis on lobbying and the political influence of the gas industry. He also lectured on energy policy. Since 2019, he has been a non-executive director of the Scottish government’s heat decarbonisation programme board.

Richard Lowes has a track record of delivering high-impact heat decarbonisation research and remains a research fellow at the University of Exeter. He has provided oral evidence to multiple UK parliamentary select committees, was an expert advisor to the National Audit Office inquiry into Great Britain’s Renewable Heat Incentive, and was an advocate for sustainable heating at the 2020 Climate Assembly UK. He had the privilege of being appointed as a specialist advisor for the UK house of commons inquiry into economy wide electrification in 2023.

He holds a first class honours degree in geography and environmental management, in addition to his master’s (with distinction) in energy policy and doctorate in the development of UK sustainable heating policy. He was appointed as a fellow of the energy institute for his expertise in energy policy in 2023.

[Episode #241] – Evolving the UK Energy System Part 2

Jan 15 2025

Mini Episode

This episode is the second in a miniseries about how the UK is transforming its energy system. If you missed Part One, featuring Adam Berman discussing the UK’s decarbonization progress, you can find it here.

In this conversation, Luke Ames Blackaby from Ofgem, the UK’s electricity and gas regulator, joins us to discuss how the agency is supporting technology development to meet the UK’s 2030 clean power and 2050 full decarbonization targets.

We explore a wide range of critical topics, including flexible electricity tariffs, cost-effective expansion of the transmission system for renewable energy, and adapting gas networks for hydrogen. Additionally, we cover integrating heat networks, leveraging electrified rail as a flexible demand asset, and using storage to manage variable renewable generation. Finally, we examine how regulations can evolve to accommodate emerging technologies like demand flexibility and optimize existing infrastructure.

Guest:

Luke Ames Blackaby is the Head of Ofgem’s Innovation Hub. The Innovation Hub is responsible for delivering Ofgem’s innovation support services, in the form of a regulatory sandboxes and bespoke advice to innovators, and for managing the delivery of Ofgem’s Strategic Innovation Fund (SIF). The Hub is also leading on the policy development for network innovation within RIIO-3, the price control setting process for gas distribution, and gas and electricity transmission, licensees for 2026-31.
