Putting a price on carbon

What if it works?

Show Notes

While the carbon tax has received a lot of negative publicity in the United States over the decades, more and more countries have been implementing carbon pricing schemes of their own. It raises the question, could carbon pricing be the cost of decarbonization? Economist Catherine Wolfram delves into economic policy and the many creative economic incentives to reduce carbon emissions, gives us a look at where things currently stand in the United States and abroad, and explores whether America...

Asegun Henry, an innovator and professor at MIT, says that energy storage is arguably the single most important technological problem we have to solve. He is developing and commercializing a new type of battery based on thermal energy conversion instead of the conventional electro-chemical reaction—a battery that’s been dubbed, “sun in a box.” He shares what it takes for a new technology to compete in today’s market and how his technology might be the gamechanger we need to decarbonize the po...

We rely on our energy systems to allow us to do work, travel, process information, and support all sorts of economic activity. MIT Professor Jessika Trancik helps us zoom out for a big picture view of how energy systems are shaped and where there is opportunity to innovate.

MIT professor and entrepreneur Ariel Furst is used to people underestimating what biology can do. But she is proving that DNA and microbes can help us decarbonize energy: DNA can be harnessed to transform carbon into useful products and in her words, “microbes are the coolest,”—they can be engineered for use in all kinds of recycling. Furst shares how sometimes the simple (and even microscopic) solutions can have big results.

As an economist, Namrata Kala has considered how incentivization can alter human behavior and help policies succeed. She leverages this expertise to help us examine how the world's most populous country, India, is thinking about clean energy and the implications of electrification on its energy demand. She also explores how economics, as well as U.S. policy shifts, might affect their trajectory.

As a clean energy source, hydrogen has shown to have a lot of potential. But when generated using fossil fuels, hydrogen production can have a large environmental impact—even if the energy source itself doesn’t generate emissions. So, what if we can get readily available hydrogen from the ground instead? Brad Hager, a professor of earth, atmospheric, and planetary sciences at MIT, explores the potential of geologic hydrogen, looks at some of the possible pitfalls, and asks what it might take ...
