Rooted in Change

Estelle Clerc - CellX

PFAS has already made a number of appearances on this show, but safely eliminating these toxic "forever chemicals" and other micropollutants remains a massive challenge.

Lukas Porz - ILLUTHERM

Decarbonizing high-temperature industrial heating remains one of the hardest challenges in the energy transition, often requiring massive amounts of fossil fuels. The ind

Magnus Ivarsson - MycoMine

Managing industrial waste without relying on energy-intensive methods remains one of the biggest challenges for the environment, often resulting in pollutants simply bein

Johann Liebeton - BioHalo

Keeping barnacles and algae off of ship hulls without poisoning the water remains a massive challenge for the maritime industry, often requiring polluting chemicals. The

Trygve Mongstad - Over Easy Solar

Aligning solar energy production with actual grid demand remains one of the hardest challenges in the energy transition, often resulting in peak generation when we need i

William Ramsay - Sixteen44

When we think about climate change, we most of the time think about CO2. But neutralizing methane, a gas with an even higher global warming potential, when it is too spre

Phillip Grimm - Pluvion

Managing extraneous water and optimizing sewer networks remains one of the hardest challenges in the water industry, requiring costly and labor-intensive monitoring. Util

Daniel Bloch - Iron Energy

Storing and transporting renewable hydrogen remains one of the hardest challenges of the energy transition, requiring complex and expensive high-pressure tanks. The indus

Frank Rattey - Planeteers

Global climate goals require massive amounts of carbon removal. Therefore, we need to find scalable, permanent solutions. Many efforts continue to rely solely on land-bas

Oscar Hållén - Cemvision

The traditional cement industry relies on proven chemistry and typically looks for minor process improvements rather than fundamental change. This has contributed to the

Tobias Sodoge - NeoCarbon

Data centers generate immense heat and require constant, energy-intensive cooling to run their servers. Those facilities typically vent that excess energy as waste, until

Thomas Bräck - Meva Energy

Heavy industries need high temperatures to run their processes, making certain processes hard to electrify. Those companies continue to rely on fossil gas, until now. Mev

Hanna Ojanen - Carbo Culture

Reaching Net Zero is one of the defining challenges of our time, but reducing emissions alone won't be enough - we also need to actively remove carbon from the atmosphere

Karthik Kunjali - Stockholm Water Technology

Clean water is one of the defining challenges of our time and even its own Sustainable Development Goal. One essential piece of the puzzle is wastewater purification. Tha

Felix Bünning - viboo

As the heating season kicks off, energy use and energy bills start climbing fast. In this episode, I talk with Felix, co-founder and CEO at viboo, who are tackling this c

Emilio Dal Re - Unbound Potential

Unbound Potential is rethinking batteries. By removing costly membranes and complex cell stacks, their membrane-free redox flow technology stores energy in two liquids wi

Frédéric Juillard - TreaTech

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 -

Lars Stegmann - CAP-XX

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

Gnanli Landrou - Oxara

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-found

Hannes Steinle - ZeroEx

Enhanced weathering uses finely ground minerals spread on farmland to speed up a natural process: rocks reacting with CO2 to form stable carbon compounds. This process no
