Catalyst with Shayle Kann

Agriculture in the U.S. produces more methane than the American oil and gas industry, and the biggest share of that agricultural methane is from enteric fermentation – essentially cow burps. Cows and other ruminant animals release methane because of the way they digest food. And as animal protein consumption rises, so will enteric emissions. It’s a problem for climate change, but also for farmers....

Plants capture hundreds of gigatons of carbon every year in timber, crops, and other forms of biomass. Much of that carbon gets released back into the atmosphere through natural processes and human intervention. But there are a few ways that we can lock it away for good, like biochar, bio-oil, and bioenergy with carbon capture and storage, or BECCS — all processes that fall under the umbrella of b...

Venture and early-stage investment in climate tech in 2023 was down 30% from 2022, according to market intelligence firm Sightline Climate. But is that a bad thing? In this episode, Shayle unpacks the findings of Sightline’s 2023 Climate Tech Investment Trends report with Kim Zou, co-founder and CEO of the firm, which also produces the popular CTVC newsletter. (Shayle is an adviser to Sightline, a...

The voluntary carbon market is a mess. Oil majors, big tech, and many other industries purchase voluntary credits hoping to offset their carbon emissions. But years of reporting have revealed major problems in the industry, from worthless credits to outright fraud. Amid allegations that many of its credits might actually worsen global warming, the CEO of the largest issuer of credits, Verra, resig...

There’s a hole in the finance world. Fighting climate change means scaling up lots of new technologies, but financing those first-of-a-kind (FOAK) projects is incredibly difficult. New technologies involving things like sustainable aviation fuel, geothermal, and direct air capture can take a decade or more to scale up. But venture capital is too expensive for FOAK projects, while infrastructure fi...

It’s time to get specific. In the power industry “long-duration energy storage” could mean anything from 4 to 10 to 100 hours of energy. But Form Energy’s Mateo Jaramillo argues that batteries in the ballpark of 100 hours hit a sweet spot, and that sweet spot deserves its own term: multi-day storage. In the 15 minute to 12 hour range, lithium-ion batteries shine, effectively displacing natural gas...

The U.S. Treasury proposed guidance last Friday that would significantly restrict what battery parts and materials can qualify for incentives in the Inflation Reduction Act. The rules label China and several other countries as “foreign entities of concern.” These rules will prevent materials and parts sourced from those countries, starting in the next few years, from counting toward the IRA’s elec...

For those of us in the U.S., Europe's strong electric vehicle market might offer a glimpse into the future of EV charging. In 2022 the electrification haven of Norway had a whopping 166 plugin-in electric vehicles per 1,000 residents. Germany had 20 per 1,000 residents and Europe’s largest fleet, based on reporting by Euronews. That’s far ahead of the U.S., which averaged 8.6 in 2022, according to...

Nuclear construction costs in the U.S. are some of the highest in the world. Recent estimates put it at more than $6,000 per kilowatt, as measured by overnight capital cost. But high costs are a problem for new small modular reactors (SMRs) too, killing what was going to be the country’s first small modular reactor before it got built. On the other hand, South Korea has some of the lowest costs in...

It’s about that time again. You sent in great questions for Shayle, and in this episode we’re tackling them with the help of Sarah Golden, vice president of energy at GreenBiz. Together Shayle and Sarah cover topics like: Load growth and whether data-center demand is good or bad for decarbonization. The crash in photovoltaic module prices and what it means for the solar industry. The impact of int...

Some technologies grab the spotlight even beyond #energytwitter, and some fly under the radar. Which ones are getting more attention than they deserve, and which aren’t getting enough? This is the episode you never knew you needed: Shayle talks to Volts host David Roberts about the most underhyped and overhyped trends in climatetech right now. David has written about clean technology for the past...

Heat pumps in 140 million U.S. homes by 2050 — that’s the goal laid out in Rewiring America’s recent report on the pace of home electrification. It’s a daunting target for a country that had heat pumps in only 17 million homes in 2020. But we’re not that far off. According to Rewiring America, the U.S. is currently on track to install about five million heat pumps by 2025, only about two and a hal...

In climatetech circles, the Inflation Reduction Act (IRA) was a big deal. The expectation was that, combined with other parts of U.S. industrial policy like the CHIPS and Science Act and Bipartisan Infrastructure Law, the IRA would transform the American economy and ultimately slash U.S. carbon emissions.  We can’t see the impact on carbon emissions yet, but we can measure the initial effects on t...

This is a partner podcast episode, brought to you by DNV. Wes Whited and Angie Ziech-Malek work for DNV designing efficiency, electrification, and decarbonization programs for utilities. And lately, they’ve been paying attention to electric forklifts. There are 1.5 million forklifts sold in the U.S. every year. And converting that vast fleet to run on lithium-ion batteries could be a cost-effectiv...

It was 2020 and plant-based meats were hot. Sales were up 45% that year and expectations were high. The industry set its sights on performing as well as plant-based beverages, which had reached about a 15% dollar share of the U.S. cow-based milk market at the time. In the $300 billion U.S. meat market, a 15% share would be a massive $45 billion prize. But then, starting in 2021, plant-based meats...

Everything's bigger in Texas—the hats, the boots, the convenience stores. But its interconnection times? They’re surprisingly short. In the U.S. it takes power generators four years on average to get approval to connect to the grid, and in some places, it takes far longer. In the Texas electricity market, it takes only about 1.5 years between interconnection request and agreement. And it costs way...

Solar geoengineering is a hot (er, cool?) topic these days. One method involves injecting a form of sulfur into the atmosphere to reflect solar radiation and help reduce global temperatures. But it could also cause unpredictable changes to ozone, rainfall, and ecosystems. So when a rogue startup began sending balloons of sulfur dioxide into the atmosphere earlier this year, it sparked outrage. But...

Last time we talked to Dr. Michael Webber, we dug into the nexus between water and energy. This episode we’re diving into food. The connections are myriad. Food itself is just a means of energy storage, and a particularly good one at that. While photosynthesis is remarkably inefficient—averaging only 0.3% globally, compared to 90% or more in an electric motor—it stores energy for weeks to years. I...

Here’s the dream: Millions of EVs plugged into their charging docks, working in concert to relieve stress on the world’s power grids. They reduce charging load or even inject energy back onto the grid. They back up renewables when the wind doesn’t blow or the sun doesn’t shine.  That’s the vision for managed charging, or V1G, and vehicle-to-grid, or V2G. There’s also a third technology called vehi...

If there were a holy grail of electric vehicle batteries, it would be low-weight, long-range, and fast-charging. It would last a million miles and cost less than anything produced today. So in the booming EV battery market, what kind of battery will check all those boxes? Who will invent it? And do we really need all those features in one battery in the first place? In this episode, Shayle talks t...

Electrification should be a field day for utilities. As we electrify the economy, adding gigafactories, charging stations, and green hydrogen hubs to the grid, the demand for power is growing for the first time in decades. For savvy utilities, there’s a lot of money to be made. But only if they can keep up.  Utilities face massive challenges to deliver the power needed for electrification – years-...

It’s the highest-intensity solar power you can get. It’s available 24/7. And you can send it anywhere on earth. All you need to do is launch a ten-by-ten kilometer array of solar panels into geosynchronous orbit, capture solar energy, and beam it to earth using a massive antenna array. Then set up a receiver a few kilometers in diameter on earth to collect that power and send it to the grid.  Soun...
