Can We Pull Carbon Out of the Air?
08/13/24 • 25 min
3 Listeners
The Paris Climate Agreement says we need to reach “net zero” carbon emissions by 2050. That means for every new carbon molecule we put in the air, we have to take one out. Even the most optimistic forecasts still anticipate burning fossil fuels well past that date. So how do we balance the carbon books? Enter direct air capture, or DAC — a mechanical process that sucks carbon out of the atmosphere — which many believe will be crucial to controlling climate change. Right now the technology is extremely expensive, energy intensive, and has never been deployed at the scale necessary to make a difference. Host Arielle Duhaime-Ross speaks with the Dr. Klaus Lackner, known as the “godfather of carbon removal”; Dr. Susan Hovorka, a professor of geology who has been burying carbon underground for decades; and Dr. Emily Grubert, associate professor of sustainable energy policy at Notre Dame.

Has the Moment for Hydrogen Finally Arrived?
Hydrogen has long been the great hope of the environmental movement. Hydrogen-powered cars; airplanes; even home heating. A single molecule could power it all. Much of that has gone nowhere. But now, hydrogen is being touted as the answer to carbon-free steel. Can we trust in our hydrogen future this time? To explore that question, host Arielle Duhaime-Ross talks to Rachael Fahkry, policy director at the Natural Resources Defense Council, and Jason Mortimer, from the company Electric Hydrogen.
