Jeff Bishop, Key Capture Energy – 92

What’s it all about?I love how Jeff and Dan have built Key Capture Energy to be a leading player in the utility scale energy storage sector since founding not many years ago. I first met and worked with Jeff Bishop three years ago, and we recorded one of the early episodes of the podcast. So much has changed in the business and the sector I wanted to share that journey, and Jeff’s thoughts and insights for energy storage for the next three to five years, and his insights into important leadershi...

Francis Wang, NanoGraf – 91

More energy dense, faster charging batteries. Batteries, or any energy storage of all natures, are so critical to the ongoing energy and mobility transitions. One of the areas that doesn’t get much thought, but is so critical, is material science, the materials which enable bigger, better, faster, more efficient batteries. This week I speak to Francis Wang, CEO of Nanograf. From PhD to entrepreneur and CEO, he has a great story to tell, and some superb insights into both the startup entrepreneur...

Stephen Fitzpatrick, Vertical Aerospace – 90

What’s it all about?The electrification of transport continues at pace (literally and metaphorically), and one of the most interesting areas of growth, particularly for those who have to deal with high levels of local and regional road traffic congestion, is electric taxi’s. One of the leading pioneers in this sector is Vertical Aerospace. I was able to speak to founder and CEO Stephen Fitzpatrick ahead of his hot footing to New York to ring the bell on their NYSE public Listing on 16th December...

Doron Myersdorf, StoreDot – 89

What’s it all about?Extreme fast charging of electric vehicles! I love batteries, and cars, and of course electric vehicles, and I’ve been watching Storedot for some time, and how they are creating batteries that can charge a car fully in 5 minutes. Now I don’t mind a 30-40 minute charge whilst stopped at a service station, or trickle charging at home, but for some people it’s still a barrier to entry, and faster charging will remove another excuse for adoption, and make it easier for us all. A ...

Jules Besnainou, Cleantech for Europe – 88

What’s it all about?I first met Jules through his work at Cleantech Group, but was delighted when I saw, via a number of VC contacts, that he was leading the Cleantech for Europe initiative. I’ve worked for and with many of the VC’s involved, and their portfolio companies. This is a great initiative, with the mission to help the EU lead the race to net zero by putting innovation at the center of the public policy debate, and building bridges between the EU’s cleantech community and policymakers....

Mark Futyan, Anesco – 86

What’s it all about?It’s great to hear about start-ups, and those journeys, but we all know scale is what we want, it’s not easy, but you can have more impact and do more ‘good’ when you have scale. I’ve seen Anesco grow over the last ten years and make a real impact in the deployment of solar and energy efficiency in particular. It was great to have time to speak to the (relatively) new CEO Mark Futyan about the company culture, growth and plans for the future, as well has his thoughts on the p...

Greg Smithies, Fifth Wall – 83

What’s it all about?I was delighted when the Fifth Wall people reached out about the podcast. For some time I’ve wanted to address areas of the climate challenge, and areas of technology that are hugely important, but don’t often get much press or attention, including on this podcast. In particular the Built Environment is of enormous importance to us all on many levels, it is of course where we live and work, and because of that impacts not just our immediate lives, but as you will hear, contri...

Patrick Sheehan, ETF Partners – 80

What’s it all about?Money and People, the two main ingredients for a successful business (a damn good product/service is the other). More specifically it’s the RIGHT money and the RIGHT people. The right people is something we specialise in at Hyperion Executive Search, but I love to engage with passionate, experienced and mission driven VC’s and Investors who can provide money and so much more. The right money! Though Patrick expresses that all money is good! We talk about future trends, and ho...

Jorg Heinemann, EnerVenue – 68

I make no apology for starting the year back talking about batteries. EnerVenue caught my eye recently after a $12m seed round, but whilst they are a very young company, their technology has been used for many years, mainly in space! They now have a way to make their technology cost competitive and not so astronomical in cost (see what I did there?). Getting energy storage right, at all scales and for various use-cases is vital to a successful energy and mobility solution. Take a listen to where...
