Hydrogen. What are you even supposed to think about it? If you’ve spent serious time focusing on climate policy, you’ve heard the hype about hydrogen — about the miraculous things that it might do to eliminate carbon pollution from cars, power plants, steel mills, or more. You’ve also seen that hype fizzle out — even as governments have poured billions of dollars into making it work.

On this week’s episode of Shift Key, Rob and Jesse give you a rough guide for how to think about clean hydrogen, which could help decarbonize the industrial — even the molecular — side of the economy by storing energy and helping to make clean steel and chemicals. Do we really need hydrogen to fight climate change? Where would it be useful? And why has it failed to take off in the past? What will Trump and China mean for global hydrogen policy? Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.

China’s greenhouse gas emissions were essentially flat this year — or they recorded a tiny increase, according to a recent report from the Centre for Research on Energy and Clean Air, or CREA. A third of experts surveyed by the report believe that its coal emissions have peaked. Has the world’s No. 1 emitter of carbon pollution now turned a corner on climate change?  

Lauri Myllyvirta is the co-founder and lead analyst at CREA, an independent research organization focused on air pollution and headquartered in Finland. Myllyvirta has worked on climate policy, pollution, and energy issues in Asia for the past decade, and he lived in Beijing from 2015 to 2019. 

On this week’s episode of Shift Key, Rob and Jesse talk with Lauri about whether China’s emissions have peaked, why the country is still building so much coal power (along with gobs of solar and wind), and the energy-intensive shift that its economy has taken in the past five years. Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.

The rise of artificial intelligence and the associated expansion of data centers is driving surging demand for new power supply. Earlier this fall at the annual meeting of Princeton University’s Andlinger Center for Energy and the Environment, Jesse sat down with a panel of experts to discuss how society can meet the growing energy demands of AI while staying on track broader decarbonization efforts.

How will we power the growing demand from AI and data centers? What role can nuclear power really play? Will AI lock us into a new generation of gas power plants? Are regulators prepared for what's coming? Jesse dives into all this and more with Allison Clements, former commissioner of the Federal Energy Regulatory Commission, Matt DeNichilo, partner at energy investment firm ECP, and Lucia Tian, head of clean energy and decarbonization technologies at Google.

Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University. Rob is off this week.

Jennifer Granholm has long been one of the most interesting figures in the Democratic Party. A former federal prosecutor, she was the governor of Michigan from 2003 to 2011, leading the state during the Great Recession and subsequent auto bailout. Since 2021, she has been the 16th U.S. Secretary of Energy. While there, she has overseen the department’s transformation from an R&D-focused agency to an aspiring engine of industrial strategy. 

On this week’s episode of Shift Key, Rob sits down with Secretary Granholm in person in New York to conduct an exit interview, of sorts. What climate policies is she most proud of — and what does she hope Democrats do better next time? What does she wish that Democrats understood about fossil fuels? And what does she think the outlook for clean energy is in the years to come? 

Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University. Jesse is off this week.

The Chinese electric automaker BYD is entering a new stage in its history. Last month, it sold more than half a million electric vehicles and plug-in hybrids. BYD has already shipped more cars this year than Ford and Honda, and it is fast coming for Volkswagen, GM, and Toyota’s crowns as the world’s three largest automakers.

Earlier this year, Rob and Jesse spoke with Ilaria Mazzocco, a senior fellow with the Trustee Chair in Chinese Business and Economics at the Center for Strategic and International Studies in Washington, D.C. She has watched China’s EV industry grow from a small regional experiment into a planet-reshaping juggernaut. On this week’s episode of Shift Key, we’re re-running that conversation — one of our favorites ever to happen on the show. We’ll be back with a new episode next week.

Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.

The Inflation Reduction Act, President Joe Biden’s landmark climate law, is the biggest investment in clean energy in American history. It is also in danger. In January, the Trump administration and a GOP Congress will take over the federal government — and they have made a variety of promises about how they’ll disrupt the law, ranging from full repeal to a more “surgical” reform approach.

On this week’s episode of Shift Key, Rob and Jesse talk with Kristina Costa, who has worked since 2022 to implement the IRA’s climate provisions at the White House. She joins us to discuss what went right about the Biden administration’s rush to implement the law, why state government capacity is holding back Democratic policy goals, and why the federal government needs more tools to support energy innovation if it wants to keep up with China. She also discusses how the administration is trying to Trump-proof the law. Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.

Here’s the bad news: The world is almost certainly going to miss the Paris Agreement’s goal of keeping global temperatures from rising beyond 1.5 degrees Celsius over pre-industrial levels. The needed emissions cuts are too large and the direction of policy too slow to lead to any other outcome. In the next few decades, global warming will slip past the 1.5 degree mark — and temperatures will keep rising.

What does that mean? What comes next? And how should we feel about that? On this week’s episode of Shift Key, Rob and Jesse chat with Kate Marvel, an associate research scientist at Columbia University and the NASA Goddard Institute for Space Studies. We talk about why every 10th of a degree matters in the fight against climate change, the difference between tipping points and destabilizing feedback loops, and how to think about climate change in a disappointing time. Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.

The rollbacks are coming. Donald Trump’s incoming administration is expected to pull the United States out of the Paris Agreement, weaken the Environmental Protection Agency’s rules for power plants and tailpipe pollution, and — potentially — rewrite or repeal big swaths of the Inflation Reduction Act. Each of those actions would seem to provide an opening for the world’s No. 1 polluter — China — to assert global leadership and zip ahead in the next generation of clean energy technology.

How will it respond? On this week’s episode of Shift Key, Rob and Jesse chat with Jeremy Wallace, the A. Doak Barnett Professor of China Studies at Johns Hopkins University. Wallace, a Heatmap contributor, helps us understand how China is thinking about Trump, the current state of China’s economy, and why China sometimes flexes its climate leadership — but just as often doesn’t. Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.

Last night, Donald Trump secured a second term in the White House. He campaigned on an aggressively pro-fossil -fuel agenda, promising to repeal the Inflation Reduction Act, Biden’s landmark 2022 climate law, and roll back Environmental Protection Agency rules governing power plant and car and truck pollution.

On this week’s episode of Shift Key, Jesse and Rob pick through the results of the election and try to figure out where climate advocates go from here. What will Trump 2.0 mean for the federal government’s climate policy? Did climate policies notch any wins at the state level on Tuesday night? And where should decarbonization advocates focus their energy in the months and years to come? Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.
