Can "second life" EV batteries work as grid-scale energy storage?

Redwood Materials has long dominated EV battery recycling, but what if they could drain every last drop of energy from those batteries before recycling them? I talk with the company’s CTO, Colin Campbell, about Redwood Energy, a new division doing just that by deploying used batteries as grid-scale storage at a massive scale. This isn’t just a side project; it’s a plan to turn a massive wave of incoming used batteries into a key resource for the grid. This is a public episode.

I chat with Sarah Goodyear and Doug Gordon, the hosts behind the unapologetic podcast “The War on Cars,” about their new book and the fight to reveal our car-dominated world as a political choice, not an inevitability. We explore the many ways automobiles suck, from the “motonormativity” that makes us angrier and more isolated behind the wheel to the devastating impact on children’s freedom and development. We also get into the positive, radical vision that animates their work: a future with fewer cars, where our streets are reclaimed for human connection and community. This is a public episode.

New York passed one of the most ambitious climate laws in the country, but is now struggling to meet its goals. I’m joined by Doreen Harris, president of NYSERDA, the agency on the front lines of implementing the law. We explore what’s working, from community solar to new transmission lines, and what isn’t, including the slow pace of scaling up renewables and decarbonizing transportation. This is a public episode.

In this episode, I talk with Seattle mayoral candidate Katie Wilson, a longtime transit and housing organizer who scored a surprise primary victory against the city’s establishment-friendly incumbent. Wilson makes the case for why her deep experience as a community organizer and coalition-builder is precisely the kind of leadership needed to restore faith in government and get big things done.

In this episode, I chat with Quaise CEO Carlos Araque about unlocking geothermal energy on a planetary scale by drilling miles into the Earth’s crust. He explains how his company’s technology vaporizes rock with microwaves to reach depths where intense heat sends the water supercritical, packing ten times the energy density of conventional geothermal. The ultimate goal: persuading the oil and gas industry to put its capital and expertise toward mining heat rather than fuels. This is a public episode.

Why should you care about a utility commission race in Georgia? Because it’s a national bellwether, a sign of how voters are going to react to skyrocketing power prices and a test of whether Democrats can get their act together. I talk with candidate Peter Hubbard and activist Brionté McCorkle about the state’s Public Service Commission, its coziness with utilities, and what reform would look like. This is a public episode.

In this episode, I chat with investor Clay Dumas of Lowercarbon Capital about the growing use of “advance market commitments” (AMCs). We discuss how this simple idea — a group of buyers commits to purchasing a set amount of a product if it can be produced — can derisk investment and jumpstart innovation in the climate economy’s toughest sectors. Clay explains what makes for a well-designed AMC and how it can accelerate the path to commercialization for everything from carbon removal to green steel. This is a public episode.

Data centers are creating a grid crunch, so what if they paid to solve it by upgrading our homes? I chat with Rewiring America’s Ari Matusiak and PG&E’s Carla Peterman about a new report proposing that hyperscalers fund household electrification to free up the grid capacity they desperately need. We explore how this reframes households as crucial energy infrastructure and creates a win-win-win for tech companies, utilities, and everyday people. This is a public episode.

High-temperature industrial heat for things like steel gets a lot of attention in clean energy world, but its somewhat less sexy cousin low-temperature industrial heat could use a little more. In this episode, I talk with Teresa Cheng (Industrious Labs) and Richard Hart (ACEEE) about how industries like beer, milk, and paper can decarbonize with industrial heat pumps and thermal storage. We dig into how electrified industry could help the grid, confront the hidden costs of sticking with gas, and talk through how grants and financing can tip the scales. This is a public episode.

In the past, Africa's natural resources have often proven to be a curse, leading to exploitation, corruption, and immiseration of indigenous people. Now it finds itself at the center of another resource boom, this time around the critical minerals that will fuel the clean energy transition (lithium, copper, etc.). Will this time be different? Patrick Kipalu argues that indigenous land rights and informed community consent are not barriers to investment, but the only way to ensure stable, equitable development. We explore how African nations can leverage their resources to benefit their own people. This is a public episode.
