The Climate Tech Podcast with Fexingo: Energy, Sustainability, and Decarbonization Companies

Most people think smart meters are just digital dials that send data back to the utility. But in cities like Helsinki and parts of California, they are becoming active behavioral tools that change how households consume energy. We look at a specific pilot program where real-time pricing coupled with simple home displays reduced peak demand by twelve percent without any hardware upgrades. The story isn't about the meter itself but about the psychology of visibility. When consumers see their usage ticking up in real time, they make different choices. We explore why feedback loops matter more than price signals alone and what this means for grid stability as we head into late summer.

With solar and wind now providing over a third of U.S. electricity in some regions, the grid faces a new bottleneck: timing. This episode explores how lithium-ion battery storage is shifting from backup power to the primary tool for balancing supply and demand. We look at specific projects in Texas and California where batteries are arbitraging energy prices, stabilizing frequency, and preventing blackouts during heatwaves. Lucas and Luna break down the economics of megawatt-hour deployments, the role of software in dispatching power, and why this technology is becoming the most critical infrastructure investment of the decade.

We dive into the specific mechanics of molten salt thermal storage and how it is becoming the missing link for dispatchable renewable energy. By looking at the operational data from recent utility-scale projects, we explore why storing heat in sand or rocks might be more economically viable than lithium-ion batteries for long-duration grid stability. We break down the levelized cost of storage, the physical chemistry involved, and the strategic decisions utilities are making to hedge against battery supply chain volatility.

Direct air capture technology is moving from experimental pilots to industrial scale, but the economics remain steep. We look at Climeworks' Mammoth facility in Iceland and its new project in Utah as case studies for what it takes to sequester one million tons of carbon annually. The conversation breaks down the energy intensity of sorbent-based systems, the critical role of cheap geothermal power, and why scaling DAC requires solving the logistics of CO2 transport and storage rather than just improving the capture chemistry. We also examine the emerging market for high-purity CO2 in beverage and agriculture sectors versus permanent geological storage, asking whether voluntary carbon credits can ever support the true cost of removal. If these conversations are useful for what you're building or running, consider supporting the show directly.

Steel production is responsible for roughly eight percent of global carbon dioxide emissions. This episode looks at how HYBRIT, a joint venture between SSAB, LKAB, and Vattenfall, is pioneering fossil-free steel using hydrogen instead of coal. We break down the technical and business case: hydrogen direct reduction, the economics of green hydrogen versus traditional blast furnaces, and why BMW and other manufacturers are already signing supply deals. We also consider the challenges—massive electricity needs, the future cost of hydrogen, and whether the green premium will ever disappear. If you've ever wondered how the steel industry, one of the hardest sectors to decarbonize, is starting to change, this episode gives you the concrete numbers and the strategic picture.

In this episode of The Climate Tech Podcast, Lucas and Luna explore the quiet revolution happening in the ammonia industry. Ammonia is one of the world's most produced chemicals, essential for fertilizers that feed nearly half the global population. But its production is responsible for over one percent of global carbon dioxide emissions. Enter green hydrogen: by splitting water with renewable electricity, green hydrogen can replace the fossil-fuel-derived hydrogen used in ammonia production, cutting emissions dramatically. We dig into the massive scale of the challenge, the economics of green ammonia, and the pioneering projects already underway, from the world's largest green ammonia plant in Saudi Arabia to innovative shipping fuel applications. We also discuss the role of policy incentives like the US Inflation Reduction Act's clean hydrogen credits, and what it will take to scale up electrolyzers. If you've ever wondered whether green hydrogen is for real, this episode gives you a grounded look at one sector where it's actually happening. Plus, Lucas and Luna share how listener support helps keep the show ad-free.

This week on The Climate Tech Podcast, Lucas and Luna explore the quiet comeback of compressed air energy storage. In California, a facility using depleted underground salt caverns is storing wind and solar power for when the grid needs it most — an idea people laughed at two decades ago. The hosts walk through how the technology works, from the physics of air compression to the surprising role of heat in making it efficient. They also crunch the numbers on costs, compare it to grid-scale batteries, and ask whether it can scale beyond niche geographies. If you have ever wondered what happens to all that renewable energy when the sun sets, this episode is for you.

Cement production is responsible for about eight percent of global carbon dioxide emissions, and the industry has struggled to decarbonize. In this episode, Lucas and Luna explore the emergence of carbon capture systems designed specifically for cement kilns, from amine-based post-combustion capture to novel mineralization processes that lock CO2 into aggregates. They discuss the economics, the policy support from the Inflation Reduction Act and the EU's Carbon Border Adjustment Mechanism, and the race to scale these technologies by the 2030s. With real numbers like the cost per ton of captured CO2 and the energy penalty of running capture units, they show why cement is now a surprising frontier for climate tech and how the industry's foundational role in construction could become its biggest advantage.

Lucas and Luna explore the quiet rise of sodium-ion batteries as a real alternative to lithium. Sodium is abundant, cheap, and works in extreme cold, making it a compelling option for grid storage and entry-level EVs. The episode digs into the chemistry, the manufacturing advantages, and the economics, using the example of a major Chinese battery maker and the first sodium-ion EV to hit the market. They discuss where sodium-ion fits — not as a lithium killer but as a complementary technology — and why investors and utilities are starting to pay attention. By the end, listeners will understand the key numbers behind sodium-ion's cost and energy density, and why the battery landscape is about to get a lot more diverse.

In this episode, we explore the quiet rise of vertical axis wind turbines in urban environments. From rooftop installations in Chicago to ambitious projects in Rotterdam, we look at how companies like Windspire Energy and the Dutch startup BladeRunner are rethinking turbine design for the built world. We unpack the physics that make vertical axis turbines more suited to turbulent city winds, the economics of small-scale generation, and the regulatory hurdles that still stand in the way. With a growing focus on distributed energy, these turbines are carving out a niche where traditional horizontal axis turbines fail. Tune in to understand why the future of urban wind power is vertical.
