Rooted in Change

Unbound Potential is rethinking batteries. By removing costly membranes and complex cell stacks, their membrane-free redox flow technology stores energy in two liquids with minimal hardware, lasting over 20,000 cycles. I chat with the company's CFO Emilio Dal Re about how it works, why it matters for the energy transition, and the recent pre-seed funding plus early pilots with companies like Amazon.

Waste streams are often overlooked, but they hold enormous potential. TreaTech has developed a technology that captures the full value of a broad range of end products - from renewable gas to clean water, salts and minerals - turning waste into valuable resources. In this episode, I chat with Frederic, co-founder of TreaTech, about how the technology works, why it’s a game-changer for the waste treatment industry and how it could help build a truly circular economy. We also dive into the challenges of scaling this approach and what’s next for the company.

Supercapacitors aren’t as well-known as batteries, but they play an important role in the energy storage landscape. Unlike batteries, they can charge and discharge almost instantly, making them ideal for applications that require short, powerful bursts of energy. In this episode, I chat with Lars Stegmann, CEO at CAP-XX, the company behind the world’s thinnest supercapacitors. We explore how the technology works, why it matters for the energy transition and how CAP-XX powers a green transition.

What if we could build without cement? In this episode, one of the world’s most used, yet climate-damaging materials makes an appearance: cement. Gnanli Landrou, co-founder of Oxara, explains how the ETH Zurich spin-off turns demolition waste and clay into clean, circular building materials. With cement-free binders that cut emissions and reduce construction waste, Oxara opens the door to affordable, low-carbon housing. Tune in to hear how the team is building a future that’s cleaner and smarter - without cement.
