Talking New Energy

111. Thermal storage for cooling commercial buildings

In this episode Jon Slowe explores how storing 'cold' can help commercial buildings shift their demand away from peak periods. Jon talks with Yaron Ben Nun, Founder & President with Israel-based Nostromo Energy, commercialising water-based energy storage in California.

110. In conversation with... Nathan Gambling

In this episode, we're getting into the nitty-gritty of issues in the heating sector. Decarbonising heat is a complex part of the energy transition, and there are lots of elements that go towards ensuring this succeeds. One element that is often overlooked is the role of the installer or engineer. In this episode, Jon Slowe is joined by Nathan Gambling, who is an expert in the world of heating installers in the UK. Nathan is the host of The BetaTalk Renewable Energy Podcast, a plumbing and heating lecturer and consultant, and a training specialist.

109. Smart thermostats for heat pumps

Heat pumps are increasingly in the news as the Ukraine crisis spurs some people to look at how they can reduce their reliance on gas. But as many listeners will know, keeping comfortable in our houses isn’t just about the heat source – it’s also very much about the controls. In this episode, we explore the interface between heat pumps and smart thermostats – at a high level, as well as getting a bit techie in looking at some of the practical challenges.
Jon Slowe is joined by Helen Boothman, Managing Director, Evergreen Energy; Karolis Petruskevicius, founder of Homely and Head of Smart Home at Evergreen Energy; Matt Trewhella, CEO of Kensa Heat Pumps; and Arthur Jouannic, Delta-EE expert on the topic of home energy management and smart thermostats.

108. The next frontier for EV charging - multi-family homes

In this episode we’re looking at EV charging solutions for people in apartment buildings and multi-family homes. When EVs were a niche market a few years ago, most people buying EVs were relatively well-off and had their own driveway. Now, as EV adoption rises and rises, that’s no longer the case. So there’s a need, and market for, equipping parking spaces in apartment buildings and multi-family homes. Jon Slowe is joined by two people at the leading edge of this market - Hilde Holdhus, Chairwoman at Norway-based Movel, and Partner at investment firm Sarsia; Bastien Batt, Managing Director at France-based Borne Recharge Service; and Delta-EE expert William van der Byl.

107. Large-scale storage of green hydrogen

In this episode, Jon discusses with Germain Hurtado, Hydrogen Project Director at Storengy and Rob Bloom, hydrogen expert at Delta-EE, how green hydrogen can be stored at scale in salt caverns. Focusing on the Hypster project in France, Jon and the guests explore how this can provide a buffer between production and demand, as well as opening up opportunities for hydrogen to be an answer to the growing need for long-duration storage.

106. Special Episode: The Energy Crisis

In this special episode of Talking New Energy, Jon Slowe, together with Delta-EE experts, explores how the energy industry and policy makers are responding to the energy crisis – and why he is frustrated that more isn’t being done on the demand side.

105. How do Finance, eMobility, and Mobility as a Service come together?

A significant proportion of vehicles are leased to customers, rather than being bought outright. What does the growth of EVs mean for leasing companies? How can leasing companies support customers in a world of electrified transport? And will mobility follow the 'as a Service' trend we increasingly see in other industries - will we see EV Mobility as a Service taking hold? To discuss this and more, Jon Slowe is joined by Nick Salkeld, COO of MHC Mobility, and Delta-EE expert Kate Armitage.

104. Heat batteries, scaling up, and Sunamp

In this episode, we're looking at the topic of storing heat. As we use more renewable heat and electrify more heat, decoupling the timing of heat demand from when it’s produced is going to be more and more important. Jon is joined by two guests – Andrew Bissell, CEO of heat battery company Sunamp, and Klara Ottosson, one of our experts on the topic here at Delta-EE.

103. Getting into the decarbonisation of heat: an energy retailer perspective

In this episode Jon talks with Alex Thwaites and Michael Harper from energy retailer OVO Energy about their activity and ambitions to help households decarbonise heat. Roxanne Pieterse, Senior Analyst, from Delta-EE adds her expert views.

102. Solar Power Purchase Agreements – In conversation with Harald Overholm, Alight

In this episode we’re looking at the business of solar power purchase agreements (or PPAs as they’re known) – essentially connecting corporate energy users with new sources of solar generation. Loyal listeners may remember a previous episode in Series 10 with Alpiq and Aquila Capital looking at PPAs in Spain, with its plentiful wind and solar resources. Today we’re heading further north – all the way to Sweden, and talking with Harald Overholm, founder and CEO of Alight, the Nordics' leading Solar PPA company.
