What if there was a way to continue using fossil fuels for energy without emitting CO2 into the atmosphere? To prepare for a new listener question about carbon capture, we're re-airing this season two episode in which Dr. Howard Herzog and Professor Brad Hager talk about capturing, using, and storing carbon emissions, and how it fits into a clean energy future.

Is hydrogen fuel a climate solution? That depends on how you produce it. Dr. Emre Gençer of the MIT Energy Initiative takes us on a tour of the hydrogen spectrum, from climate-polluting “gray” hydrogen made from natural gas to the much more promising “green” hydrogen made with renewable electricity.

Just 20 years ago, hydrogen cars and battery electric cars were pretty evenly matched as clean alternatives to gas-powered vehicles. But today, batteries are way ahead: the big car companies are rapidly electrifying their lineups, while only a few hydrogen cars are available. What happened? Sergey Paltsev, senior research scientist at the MIT Energy Initiative, helps TILclimate answer this listener question.

Hydrogen gas acts like a fossil fuel, but with no carbon emissions. Is it the silver bullet we’ve been waiting for? To prepare for some new listener questions about hydrogen energy, we're re-airing this season four episode in which Prof. Svetlana Ikonnikova of the Technical University of Munich explains how hydrogen works and its potential in the energy transition.

Wind power is the largest source of clean, renewable energy in the United States. But the large turbines that create that power can endanger wildlife. MIT Professor Michael Howland returns to the podcast to answer a listener's question about the risks of wind energy to birds—and explain how wind turbines compare to coal plants, power lines, office towers, housecats, and other threats to birdlife in the modern world.

You might have heard how wind turbines failed in Texas during a terrible cold front in 2021. Does this mean we can’t rely on this clean, renewable source of energy when the weather turns extreme? MIT Professor Michael Howland joins the podcast to explain how wind turbine operators prepare for frigid conditions, and why some turbines failed in Texas while others are working fine in Antarctica.

Plants take in CO2 from the air to grow—and today’s atmosphere has about 50% more CO2 than it did before we started burning massive amounts of fossil fuels. So, is that great news for plants? Prof. David Des Marais, a plant ecologist at MIT, helps answer this listener question.

The sixth season of Today I Learned: Climate is coming in two weeks, and this time we’re doing something a little different. People all around the world write into our team with questions about climate change. So this season, we’re working with scientists and experts at MIT and beyond, to answer those questions in language we can all understand.

The United States has a goal to power the country with 100% clean electricity by 2035. Unfortunately, our energy regulations are not set up to make this much change this quickly. Energy economist John Parsons of MIT joins the show to explain how much clean energy infrastructure we need to build, the obstacles to building it, and reform ideas to transform our energy system on the timeline our climate goals demand.

The large majority of new energy we’re building today comes from clean, renewable wind and solar projects. But to keep building wind and solar at this pace, we need energy storage: technologies that save energy when the weather is favorable, and use it when wind and sun are scarce. Prof. Asegun Henry joins TILclimate to explain how energy storage works, what storage technologies are out there, and how much we need to build to make wind and solar dominant.
