What if we could unearth natural hydrogen? In this episode, Emmanuel from Mantle8 shares how they are pioneering the search for the Earth’s naturally occurring hydrogen reservoirs. As a new generation of geologists, Mantle8 uses bottom-up exploration and decades of expertise to unlock this untapped energy source. We discuss the science behind natural hydrogen and why it matters, how Mantle8’s approach differs from traditional approaches and what their secret sauce is. Natural hydrogen is one of the hottest topics in the climate tech industry right now, so this is a conversation you won’t want to miss!

What if designing district heating networks became simple? In this episode, I sit down with Stefano, founder and CEO of Planeto, to explore how their technology transforms how energy planners develop district heating and cooling systems. Those networks are crucial for the energy transition, yet often overlooked. Planeto makes creating efficient, future-proof networks that accelerate the energy transition easier. Stefano shares the inspiration behind the company, the challenges of scaling such a solution, and why district energy is a crucial piece of the clean energy puzzle. Tune in to learn how digital tools can unlock the future of urban heating...

What if melting and freezing powered the world? In this episode, we dive into the fascinating world of phase-change materials and their game-changing role in energy storage. By leveraging the unique properties of those materials, Cartesian has developed a solution that efficiently stores and releases energy as materials transition between solid and liquid states. Co-founder and CTO Alexis shares how he identified the solution, how it works in practice, its applications in the built environment and its future potential. If you're interested in storage solutions, this one is for you.

What if we unlocked the full potential of underground heat? In this episode, we dive into how Enerdrape is revolutionizing renewable energy by turning underground spaces into sources of heating and cooling with the world’s first geothermal panel technology. This patented solution harnesses shallow geothermal without drilling or direct ground contact. Co-founder and CEO Margaux explains how parking lots, tunnels, and other underground spaces can become sustainable energy sources, reducing CO₂ emissions and transforming building energy systems. Learn why this technology could redefine how we think about renewable heating and cooling.
