Christmas Special!

Episode notes

Cosy up with the whole team this Christmas Day as we take a look back at the year that was 2024.

#176 - Will Rowe | Octopus Energy

Scheduled for 22 Jul 2026

What do you get when you cross the world's most innovative energy company with the world's largest battery maker? Swaptopus — a joint venture between Octopus Energy and CATL that's bringing HGV battery swapping to the UK and Europe. And the man growing it is Will Rowe, Entrepreneur in Residence at Octopus Energy, who joins us this week from a tennis club, the day after selling his house. Commitment. Will explains why battery swapping cracks the three problems that have stalled electric trucking: grid connections, charging downtime, and the mismatch between when trucks need power and when power is cheap. Swap a battery in minutes, keep the truck earning, and let the swapped-out batteries do a second job — because a network of stations full of batteries is also a virtual power plant, storing cheap renewable energy and feeding it back when the grid needs it. This isn't just a transport play; it's an energy infrastructure play. He's refreshingly blunt about the road that led here, too. Will previously founded a hydrogen business for exactly this market — and he tells us candidly why it didn't work, why losing two-thirds of your energy is no route to energy security, and what China's thousand-to-one preference for batteries over hydrogen tells us about where this is all heading. His verdict on hydrogen for transport is one you'll want to hear in full. Along the way we get into: - **Why trucks are the easy win** — 32 TWh of new annual electricity demand if the UK's trucks go electric, lowering bills for everyone, while governments obsess over data centres instead - **Autonomy changing everything** — a customer planning to go from 60 to 160 hours of weekly truck utilisation, and what cab-free, 24/7 freight means for an industry whose two biggest costs are labour and fuel - **Bringing Chinese OEMs to Europe** — and conversations underway with four of the five biggest European truck makers - **Geography-specific energy strategies** — why a swap station in solar-rich Spain looks nothing like one in windy Britain - **Growing up dyslexic with a reading age of six**, passing A-levels anyway, and why resilience — and a mum who insisted he could do anything — mattered more than school ever did - **Honest talk about failure** — why it hurts, what it teaches, and why loving the problem matters more than loving your first solution And when handed the EV Café Magic Wand, Will's wish is deliberately unglamorous and absolutely fundamental: **just make electricity cheaper.** Get that right, he argues, and the business case for electrifying everything falls into place on its own. --- **Connect with Will:** [LinkedIn](https://www.linkedin.com/in/will-rowe-55ab9816/) **Octopus Energy:** [octopus.energy](https://octopus.energy/)

#175 - Paul Jewell | CarCloud

Published 15 Jul 2026

Most households and small businesses don't have an automotive expert on hand, just a relative who gets cornered at barbecues or "someone who used to be a mechanic" now responsible for a multi-million-pound fleet. That gap is the problem Paul Jewell built CarCloud to fix. Paul joins Paul Kirby and Sara Sloman to explain how CarCloud surfaces the MOT deadlines, lease endings and maintenance costs that usually blindside drivers, pairing each one with a solution rather than just a warning. He makes the case for the SME sector, not the big fleets, as the real engine of electric van and car growth. He also covers his work in last-mile transport: 10,000 pedal-assisted, motorcycle-grade electric bikes already on UK roads, care workers using them to fit more home visits into a day, and a new grocery sidecar that carries 40 kilos for around 14p per 50 miles. Along the way Paul traces his approach back to selling used cars in Birmingham's subprime credit era, tells the story of a remarkable homeless man who taught him chess and life lessons as a kid, wishes for baseline foods to be sold "net free" with no VAT or profit attached, and sets out CarCloud's next phase: automotive and mobility banking that returns real value to the driver. **Connect with Paul Jewell:** - LinkedIn: <https://www.linkedin.com/in/paul-jewell-55476122/> - CarCloud: <https://carcloudsolutions.com>

#174 - Nikolaus Mayerhofer & Alexander Millinger | Aviloo

Published 08 Jul 2026

How do you actually know what's left in a used EV battery? Nikolaus Mayerhofer and Alexander Millinger from **Aviloo** join us to draw the line between a real diagnostic and a glorified readout — and why that difference decides what a second-hand electric car or van is worth. NiKo has been building electric things since he was 12, soldering together his first e-bike back in 1987 and developing battery management systems by 19. That four decades of battery engineering — lead acid, nickel cadmium, lithium iron phosphate, NMC — is now baked into Aviloo's three-minute flash test, which pulls up to 50,000 data samples through the OBD port, sends them to the cloud, and returns an accurate, independent State of Health certificate. Eight years of collected data from thousands of vehicles (over 50 million kilometres) sits behind every result, and (from July) a UK warranty backs each certificate. We get into the things the surface won't tell you: - Why **mileage no longer equals battery health** — a study of 600 Model 3s found consumption varying by a factor of two depending purely on how they were driven and charged - How charging to 100% every night, hammering the autobahn, and preheating all quietly age a pack — and why average degradation is fine but the *variance* is the reason you test before you buy - The honest take on fast charging, solid-state hype, and why a Model S still runs a 40-year-old cell format - Battery second life: diagnostics feeding power storage in Japan, reuse from scrapped vehicles, and what happens when OEMs stop making modules - Scaling Aviloo from two friends talking on mountain bike rides to 100+ people and one million tests sold — across the UK, US, Benelux and Asia **Guests:** - Nikolaus Mayerhofer, Founder & CEO — [LinkedIn](https://www.linkedin.com/in/nikolaus-mayerhofer-014b5635/) - Alexander Millinger — [LinkedIn](https://www.linkedin.com/in/alexmillinger/) - Aviloo — [aviloo.com](https://aviloo.com/)

#173 - Jamie Sands | Welch Group

Published 01 Jul 2026

**Guest:** Jamie Sands — Operator-led zero-emission freight and innovation | TwentyForty | Welch Group **Company:** Welch Group ([welchgroup.co.uk](https://welchgroup.co.uk) · [twentyforty.uk](https://twentyforty.uk)) **LinkedIn:** [linkedin.com/in/j-sands](https://www.linkedin.com/in/j-sands/) --- What does a 92-year-old, family-owned haulier with 70 trucks know about the future of freight that the multinationals don't? Quite a lot, it turns out. Jamie Sands is Head of Solutions at Welch Group — a role that, as he points out, doesn't exist in most operators — and he joins us to explain why a regional independent from the east of England is winning tenders against the big 3PLs on something other than price. We get into the commercial logic underneath the green badge: how Welch turns its fleet into a test bed for startups in exchange for preferential terms, why the "green premium" basically doesn't exist, and how being two steps ahead on scope three reporting now wins business outright. Jamie makes the case that decarbonisation is really an energy and infrastructure problem, not a vehicle one — and that the smart play for an operator is treating charging, energy arbitrage and demand response as new revenue, not just a cost to swallow. There's plenty for the technically curious too: system-level thinking across siloed networks, what L4 and L5 autonomy actually mean for hub-to-hub night runs, why he's done arguing about hydrogen, and why "technology neutrality" can quietly become an excuse to do nothing until the 2035 cliff edge arrives. Jamie also walks us through TwentyForty, the not-for-profit he's built to pull other independent operators into the research, the media and the policy conversation — including the 12 Pillars framework for getting the whole industry talking to itself. Away from the trucks, Jamie talks music, comic books, a Project Hail Mary obsession, staying genuinely calm in an industry that runs on chaos, and the loss of a close friend that pushed him to do work that actually matters. He closes with one wish that doubles as his whole mission: that operators — the people this transition is being done *to* — get a seat in the rooms where it's being decided. Plenty of marginal gains, one or two God complexes, and a reminder that the future we're all hoping for is mostly available right now, if we work together. **Connect with Jamie:** [LinkedIn](https://www.linkedin.com/in/j-sands/) **Welch Group:** [welchgroup.co.uk](https://welchgroup.co.uk) **TwentyForty:** [twentyforty.uk](https://twentyforty.uk)
