Catalyst with Shayle Kann

The bad news: The refrigerants we use in air conditioners, fridges, and vehicles absorb hundreds to thousands of times more heat than carbon dioxide does. The good news: We’re in the middle of a global effort to replace them with lower impact alternatives.  Will we replace them fast enough to hit climate targets? And in the meantime, can we prevent them from leaking into the atmosphere? In this episode, Shayle talks to Ian McGavisk, senior advisor at RMI for carbon-free buildings. An industry veteran, he recently co-authored a report on recovering residential AC refrigerants in the U.S., which have the carbon equivalent of 1.7 million cars. (Ian also works in business development at Transaera. Energy Impact Partners, where Shayle works, invests in Transaera.). Shayle and Ian cover topics like: The sources of emissions in the refrigerant lifecycle  The economics of recovering and reclaiming refrigerants Alternatives with low global warming potential and their tradeoffs, such as efficiency, flammability and concerns about forever chemicals Recommended resources RMI: Refrigerant Reclamation Project Drawdown: Refrigerant Management Project Drawdown: Alternative Refrigerants EPA: Transitioning to Low-GWP Alternatives in Commercial Refrigeration UN Environmental Programme: Montreal Protocol On Substances That Deplete The Ozone Layer, Report Of The Technology And Economic Assessment Panel, May 2024  Catalyst is brought to you by EnergyHub.

This might be our wonkiest topic yet: Techno-economic analysis, or TEA.  Before a startup proves its technology is commercially viable, it models how a technology would work. These TEAs include things like assumptions about inputs, prices, and market landscape. They help investors and entrepreneurs answer the question, will this technology compete? TEAs are important to the success of an early-stage climate-tech company. And a lot of startups get them wrong. As an investor at Energy Impact Partners (EIP), Shayle and his team see a lot of TEAs—and have some pet peeves. So what can startups do to improve their TEAs? This episode is a re-run from October 2023. We’re making a new episode on TEAs soon – stay tuned. But to start, we’re running this episode as a way to set up our next one. In this episode, Shayle talks to his colleagues Dr. Greg Thiel, EIP’s director of technology, and Dr. Melissa Ball, EIP’s associate director of technology. They cover topics like: Bad assumptions about things like levelized cost of production  Focusing on a component instead of a system Focusing on unhelpful metrics Using false precision—something Shayle calls “modeling theater” Recommended Resources: Activate: Techonomics: Establishing best practices in early stage technology modeling Department of Energy: Techno-economic, Energy, & Carbon Heuristic Tool for Early-Stage Technologies (TECHTEST) Tool National Renewable Energy Laboratory: Techno-Economic Analysis Catalyst is brought to you by EnergyHub.

We capture concentrated methane emissions from point sources like dairy barns, landfills, and coal mines. Mitigating methane emissions is essential to hitting net-zero targets, but could we capture diluted gasses straight from the atmosphere, too?  In this episode, Shayle talks to Dr. Gabrielle Dreyfus, Chief Scientist at the Institute For Governance & Sustainable Development, about a National Academy of Sciences report on the unexplored area of methane removal. Gabrielle chaired the committee behind the report. Shayle and Gabrielle cover topics like: Why methane removal may be critical to addressing methane from hard-to-abate sources, like enteric emissions and tropical wetlands Key differences between methane removal and carbon dioxide removal How reducing methane in the atmosphere may also reduce its atmospheric lifetime  Technological pathways, including reactors, concentrators, surface treatments, ecosystem uptake enhancement, and atmospheric oxidation enhancement The potential for combining methane and carbon dioxide removal in direct air capture Recommended resources Catalyst: Why are we still flaring gas?

AI is enabling a multitude of solutions across power, industry, and transportation. But AI energy demands are increasingly stressing the electric grid — creating a bottleneck for growth and new challenges for clean energy supply. The mounting tension highlights the need for an energy-first approach to computing.  Developer Crusoe is building AI infrastructure that takes advantage of clean energy to power workloads for AI modeling. Likewise, Nvidia, Crusoe’s primary GPU supplier, has been consistently improving the energy efficiency of its GPUs. Both demonstrate the innovation that’s happening in the marketplace to create a 'climate-aligned cloud' for customers.    In the AI era, how do you build data centers with an energy-first approach? In this Frontier Forum, Stephen Lacey explores all sides of the AI-energy nexus with talks with Chase Lochmiller, the co-founder and CEO. They discuss innovations in data center design, why the energy demands of AI could be higher than projected, and why that shouldn't scare us. Chase Lochmiller will be speaking at Latitude Media’s Transition-AI conference on December 3rd in Washington, DC. Get your tickets here.
