In this episode of Leaders in Cleantech, I speak with Joachim Lohse, CEO and co-founder of Ampcontrol, about his journey from writing LinkedIn blog posts as a young consultant to founding one of Europe’s most innovative smart charging software companies. We discuss the technical and leadership challenges of scaling a company at the heart of the EV transition, and what it really takes to support the electrification of critical infrastructure like logistics fleets, ports, and buses.

Ampcontrol is tackling some of the most complex problems in fleet electrification—from grid constraints and site-level optimisation, to uptime, scheduling, and energy cost reduction—and Joachim shares both the strategic decisions and hard-won lessons from the last six years of building the business.

We also touch on the importance of predictable policy, the rising complexity of fleet charging logistics, and the cultural principles that shape his international team.

Joachim Lohse is the founder and CEO of Ampcontrol, the leading AI-powered smart charging software that optimizes electric fleets. Since 2019, Joachim has collaborated with charging networks, utilities, and fleet operators worldwide to lower total charging costs and ensure reliable operations during the transition to electric vehicles.

Joachim is a recognized leader in the e-mobility space, working closely with key stakeholders to shape the future of electric transportation around the world.

Hydrogen has for decades been talked about as the fuel of the future, the economics, among other things stand it’s way, producing cheap hydrogen isn’t easy, but what if nature has already done the hard work for us? In this episode of Leaders in Cleantech, I speak with Emmanuel Masini, founder and CEO of Mantle8, a pioneering natural hydrogen exploration company. We dive into Emmanuel’s journey from geologist to entrepreneur, why natural hydrogen could be a game-changing addition to the energy mix, and how Mantle8’s technology is accelerating the race to unlock this overlooked resource.

Episode Notes

In this conversation, Emmanuel and I explore the promise of natural hydrogen — also called geological or white hydrogen. Unlike green or blue hydrogen, natural hydrogen is formed by the Earth itself, waiting to be discovered and harnessed.

About Emmanuel (Manu) Masini

Emmanuel Masini is a geoscientist, entrepreneur and founder of Mantle8 – a pioneering energy company advancing the exploration and extraction of natural hydrogen as a low-cost, ultra-low-emissions energy source.

With more than a decade of experience in structural geology, subsurface modelling and energy systems, Emmanuel has led geoscience projects across Europe, North Africa and the Middle East. Before founding Mantle8, he co-founded the geology-focused research and consulting company M&U and worked with Total on applied geoscience projects. Of note, is Masini’s leadership of the "Orogen Research" program, whilst at M&U and at Total. This program is a collaborative effort between Total, the French National Centre for Scientific Research (CNRS), and the French Geological Survey (BRGM) involving approximately one hundred researchers, which focuses on the study of orogens, which are mountain ranges formed by the collision of tectonic plates. He also contributed to major research initiatives with the Strasbourg, Grenoble, Toulouse and Austin Universities.

He holds a PhD in structural geology from the University of Strasbourg.

About Mantle8

Mantle8 is a natural hydrogen exploration company based in France. Founded by Emmanuel Masini in 2024, Mantle8 brings together a team of geoscientists with 20 years of experience in the field that has previously worked together as M&U, a geology research and consulting company. Mantle8 has developed geoscience-based technologies that detect the best natural

Rewiring Energy: Disruption, Transparency, and Scaling with Purpose – Joe McDonald, TEM

In this energised episode, David Hunt is joined by Joe McDonald, Co-founder and CEO of TEM – a fast-scaling UK energytech startup reshaping how energy transactions are done. From his early days at LimeJump and the acquisition by Shell, to co-founding TEM and challenging the very core of how electricity is bought, sold, and valued – Joe shares a story of timing, execution, and bold ambition.

Joe and David dive into:

• The broken nature of the wholesale electricity market – and how TEM is fixing it with AI-driven infrastructure
• Why energy transparency is the antidote to greenwashing
• How scaling culture and teams in a remote-first world requires deep intentionality
• Lessons from Shell, LimeJump, and what it really means to build a challenger business
• Fundraising, lucky timing, and the power of storytelling in startup success

From disrupting energy incumbents to reimagining organisational design, this is a deep and inspiring episode for cleantech entrepreneurs, investors, and energy innovators alike.
