What’s The Cost Of Being Unprepared? | Deep Dive Ukraine 05: Ben Parsons
Through nearly five years of war, Ukraine has been forced to adapt on the fly as attacks target its energy infrastructure, and the country has been ingenious in finding new ways to generate, distribute and protect power. Its experience has exposed vulnerabilities in the rest of Europe’s energy systems, and raises the difficult question of how well prepared our own energy systems are for disruption. In the fifth episode of our Deep Dive Ukraine series, Michael Liebreich is joined by Ben Parsons,...

How The Midterms Will Change US Energy & Climate | Ep282: David Victor
Despite the Trump administration's efforts to roll back clean energy subsidies and climate policies, America's energy transition is proving more resilient than many expected. Solar and battery deployment continues, nuclear power is attracting billions in private investment, and demand for electricity is surging. But after a historic set of midterms where does the US go from here? In this episode of Cleaning Up, host Bryony Worthington speaks to David Victor, Professor of Innovation and Public...

Mexico Is On The Brink Of A Solar Boom | Ep281: Alberto Estefan
Mexico’s energy future is closely tied to its neighbour to the north. It imports much of its natural gas from the US, but could it soon be exporting clean electricity, or even data, in return? With electricity demand surging, Mexico is preparing for a major expansion of its power system, with 30GW of new generation planned by 2030 and more than $40bn in potential investment. This week on Cleaning Up, Bryony Worthington speaks to Alberto Estefan, Managing Director of Energy Infrastructure at A...

How To Run An Electricity Grid In A State Of War | Deep Dive Ukraine 04: Vitalii Zaichenko & Volodymyr Kudrytskyi
The grid is one of the most important assets in any functioning energy system, transmitting electricity from where it's generated to where it's needed. In Ukraine, that challenge is enormous. The country is very big, 1,300 kilometers from east to west, almost the distance from London to Rome. And the system is under constant attack from Russia, which targets the grid with everything from tiny drones to ballistic missiles. In this fourth episode of our Ukraine Deep Dive, we're featuring two...

How Will The Russia-Ukraine War Come To An End? Deep Dive Ukraine 03: John E. Herbst
One of the biggest questions when it comes to the brutal and drawn-out Russia-Ukraine war is how it can be brought to an end, and crucially, could it ever be replaced by a stable peace? To understand this, we have to ask not just where we are now, but how we got here. For Episode 3 of our Deep Dive Ukraine, Michael Liebreich is in Kyiv with John E. Herbst, Senior Director of the Atlantic Council’s Eurasia Centre and former US Ambassador to Ukraine, to explore the origins of the Russia-Ukraine...

We Need More Metals Than Ever. But at What Cost? | Ep279: Rohitesh Dhawan
The world needs more metals than ever before, but can the mining industry deliver the resources responsibly? The energy transition depends on the mining industry, yet the sector faces hard questions over coal, carbon emissions, environmental damage and the rights of the communities whose land and resources it extracts. This week on Cleaning Up, Michael Liebreich puts those questions directly to Rohitesh ‘Ro’ Dhawan, President and CEO of the International Council on Mining and Metals (ICMM). C...

The Race to Rebuild Ukraine's Energy Infrastructure | Deep Dive 02: Andrii Gerus & Dmytro Boroday
Can you make energy investments work in a country at war? Since Russia’s full-scale invasion in 2022, repeated attacks on Ukraine’s energy infrastructure have devastated its power system. By spring 2024, the country’s dispatchable generating capacity had fallen from 38 GW before the war to just 12 GW, leaving electricity in short supply and heating disrupted for many households. For this week’s Deep Dive Ukraine, Michael Liebreich is in Kyiv speaking to Andrii Gerus, Chair of the Ukrainian Pa...

Is Nuclear Fusion About To Have A Theranos Moment? Ep 277: Sir Steven Cowley
There's an old joke that energy from nuclear fusion is 30 years away and always will be. For many decades, the industry did little to spoil the fun, running mammoth and unwieldy research projects, hoovering up a few billion dollars every science funding cycle and announcing breakthroughs that were scientifically interesting, but did little to move us towards actual production of electricity. Then three things happened. First, perhaps emboldened by Elon Musk's successful disruption of the space ...

The Scandal at The Heart of The Energy Transition | Ep275: Jan Rosenow
Around two-thirds of the energy we put into today’s energy system ends up as rejected heat. So are we measuring the energy transition all wrong? Professor Jan Rosenow joins Michael Liebreich to unpack the “primary energy fallacy”: why focusing on the energy going into the system can obscure the useful energy we actually get out. They explore why electrification can dramatically reduce energy demand, and what genuine systems thinking means for efficiency, waste heat and infrastructure. They...

The Race Is On To Control AI | Episode 274: Afonso Salema & Sam Winter-Levy
More than 80% of the world’s advanced AI compute is concentrated in the US and China. For Europe and other middle powers, the question may no longer be how to win the AI race, but how to avoid becoming dangerously dependent on those that do. This week on Cleaning Up, James Cameron, Chair of Cleaning Up’s Editorial Council, takes over as guest host. He speaks with Sam Winter-Levy, Senior Fellow at the Carnegie Endowment for International Peace, and Afonso Salema, CEO of Exus Digital and founde...

The Next Frontier of Electrification? Industrial Heat | Ep271: James Macnaghten
Around the world, factories making food, drink, pharmaceuticals and other everyday products rely on steam, often produced by fossil-fuel boilers. James Macnaghten, founder and CEO of Caldera, is betting that thermal batteries can provide a cheaper and more flexible alternative that stores electricity as heat, and delivers steam on demand. This week on Cleaning Up, Bryony Worthington visits Caldera's factory to see how it makes its heat batteries: combining recycled aluminium and iron ore pell...

AI Has An Electricity Problem | Ep270: Arshad Mansoor
Will AI break the grid? As hyperscalers race to build ever-larger data centres, electricity demand is soaring. The question is no longer whether power demand will grow, but by how much, how quickly, and whether the grid can deliver. This week, Michael Liebreich is joined by Arshad Mansoor, President & CEO of the Electric Power Research Institute (EPRI), one of the world's leading energy research organisations.

How Renewables Are Replacing Australia's Ageing Coal Fleet | Deep Dive Australia 07: Paul Simshauser
Australia has one of the world's fastest-moving electricity systems. It leads the world in rooftop solar, has deployed grid-scale batteries at extraordinary speed, and is now starting to replace its ageing coal fleet with cleaner sources of energy. But as renewable costs rise and electricity demand grows, can the transition remain affordable while maintaining a reliable power system?

The Crisis Forcing An Energy Revolution | Ep268: Jonathan Maxwell
The UK is heavily exposed to global energy markets and has some of the highest electricity prices in Europe. At the same time, vast amounts of heat generated across industry and infrastructure go unused. Whether it should be called "waste" is a matter of debate, but could making better use of the energy we already produce be one of the biggest untapped opportunities in the energy transition? This week, Michael Liebreich is joined by Jonathan Maxwell, founder and CEO of SDCL, a specialist inve...
