Ever since Kathryn Porter appeared on the podcast, a storm has erupted in the British media, relentlessly tearing into wind energy and branding its storage as hopelessly inefficient. Today we have the CEO of Invinity, Jonathan Marren, who is Britain's largest liquid flow battery producer, who gives the solution.

Why isn’t lithium-ion enough for a grid powered by wind and solar?

In this week's episode, Jonathan explains how vanadium flow batteries and long-duration energy storage can reshape the electricity system.

Jonathan sits down with our host, Alex Wolfe, to explore the fundamental differences between lithium-ion and flow batteries, what Invinity set out to solve and what global deployments across 17 countries reveal about how long-duration storage is actually used. They also discuss falling battery costs, lessons from China, manufacturing breakthroughs and the policy and investment changes needed to unlock grid-scale storage.

Jonathan Marren is the Chief Executive Officer (CEO) of Invinity Energy Systems, a leading developer of vanadium flow batteries for long-duration energy storage, having stepped into the permanent role in September 2024 after serving as CFO/Chief Development Officer (CDO). With over 20 years in energy finance and strategy, Jonathan brings extensive experience from roles at Singer Capital Markets and Peel Hunt, focusing on corporate finance and M&A for energy and cleantech firms before leading Invinity.

In this episode, our host, Alex Wolfe and Atlantic Council's Landon Derentz discuss the evolving energy landscape, particularly focusing on the implications of the USA foreign policy towards Venezuela. Landon goes into great detail about the very different positions of Chevron, Repsol and Exxon. There was a unique meeting on January 6th in the White House between Trump and USA's biggest energy leaders.

The Wolfe Power Club's in-depth analysis with Landon, the previous Director of Energy at the White House shows that when the Venezuelan sanctions are lifted, there could be an upside of 250,000 barrels per day.

Our host Alex has used over 60 guests in 2025 to shape his opinion on where to invest his own money for 2026. Alex has picked 10 different companies across the energy industry, from lithium to oil and gas. There is an energy area that Alex is not definitely not investing into, money is going towards new solutions and there is some golden-oldies in there!

Throughout 2026, every quarter, we will review what is happening to the ten companies' share price and Alex's investments. We will also put money into basic S&P-500 and FTSE 100 trackers, will the trackers beat the energy companies?!

Our host Alex Wolfe welcomes RM Sotheby’s Director of Private Sales, Harvey Stanley, back to the podcast for a festive Christmas special reviewing a landmark year in the global car auction market.

Harvey shares behind-the-scenes insights into RM Sotheby’s biggest moments of 2025 including the record-breaking Ferrari Le Mans sale in Paris and the discreet multi-million-dollar sale of Ayrton Senna’s iconic 1991 Formula 1 McLaren. We also explore auction records, sealed bidding, 1990s supercar trends, influencer buyers and why some classics struggled to meet reserve. There was a rockstar moment where they helicoptered in Gordon Murrary's S1 LM into Las Vegas auction.

Looking ahead to 2026, Alex and Harvey discuss must-attend events, potential record-setting lots and advice for aspiring auctioneers entering the industry. Alex and Harvey look forward to meeting up at the auctions in Monaco and London in 2026.

This week, the podcast reports from the POWERful Women Annual Conference, one of the most influential gatherings in the global energy calendar. In a year where the UK prepares for 40% of women to be in energy leading roles by 2030, the stakes have never been higher and neither has the opportunity to reshape who leads the industry.

Across a packed day of panels, workshops and networking, our host, Alex Wolfe, interviewed an extraordinary lineup of energy leaders, policymakers and diversity champions. They all stand by one clear message: advancing gender balance in energy leadership is essential to powering the future.

Wolfe Power Club and POWERful Women will be at the upcoming International Energy Week in February 2026.

Special thanks to our featured guests for contributing to this episode (in order of appearance):

Chris McDonald MP (Energy Minister)
Jessica Taylor (Korn Ferry)
