A Beginner’s Guide to the Hydrogen Economy

Rob and Jesse go deep on the universe’s smallest molecule.

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.

Here is an excerpt from our conversation:

Jesse Jenkins: This is the next crazy thing that I think is just starting to kind of bubble up to the public awareness: Basically, hydrogen itself is not a climate forcer. It doesn’t warm the planet the way methane or [hydrofluorocarbons] or CO2 does. But it does react in the atmosphere in ways that increase the concentration of greenhouse gases.

Robinson Meyer: I think specifically that right now, we talk about when methane leaks into the atmosphere. And it may apply to other greenhouse gases, too, but the big one that you tend to hear about is that when methane leaks into the atmosphere from natural gas — and of course, we’re very worried about methane leaks. Because the thing about methane is that it traps a lot of heat, but it breaks down really quickly, right? So it tends to break down, unlike carbon dioxide, which, when you release it into the atmosphere. sticks around for millennia. When you release it into the atmosphere, it captures a lot of heat, but then breaks down into a smaller amount of CO2 after about 20 years.

The issue, and why it breaks down, that — we never talk about this, or we had no need to talk about this until hydrogen — and it’s crazy because the world is a closed system, or a largely closed system, right? Why it breaks down is it reacts with the free hydroxyl radicals floating around in the atmosphere.

Jenkins: Right, OH molecules.

Meyer: Well, what else reacts with OH molecules? Hydrogen. And so if we leak too much industrially produced hydrogen into the atmosphere, it could mess with the rate of breakdown of all methane in the global atmosphere, and thus increase the global warming potential of natural gas.

Jenkins: It makes the methane last, traps more heat, yeah. So let the record show that Robinson Meyer, the journalist, accurately captured the atmospheric chemistry of this process better than Jesse Jenkins, professor at Princeton. Nicely done.

The Startup Behind Lamppost-Mounted EV Chargers Pulls Into the Garage

Voltpost announced two new models today designed to mount on walls and ceilings.

Voltpost, the company putting electric vehicle chargers on lampposts, is now expanding to parking garages.

On Wednesday, the company unveiled two new configurations that can attach to the walls and ceilings of parking garages, lots, and other locations without easy access to streetlights or utility poles. Like Voltpost’s signature pole-mounted design, the ceiling- and wall-mounted options avoid the expensive construction work required by freestanding charging infrastructure. In theory at least, that should allow the company to deploy more chargers faster.

Current conditions: A sleepy Atlantic hurricane season just snapped to attention as two tropical storms started forming near the Caribbean and off Africa’s coast • Southern California is bracing for a week of triple-digit temperatures • The Hawk Fire has forced 42,000 people to evacuate an area near Reno, Nevada.


THE TOP FIVE

1. EPA is limiting public input on data centers

The Environmental Protection Agency plans to repeal a federal rule requiring states to publicize and solicit comments on applications for air pollution permits for various industrial facilities, including new data centers and power plants that provide the electricity they need. The move, The New York Times cautioned, “could prevent residents from raising concerns about — or even learning about — data centers before permits are approved and construction starts.” Three-quarters of Americans now oppose data centers built near their homes, according to the latest polling from Heatmap Pro. That’s up from less than half last year.
