The Story of Nuclear Power: Coming this Fall from Closing the Gap
The award-winning Closing the Gap podcast is returning for a third season with a special series. It’s a sweeping look at the past, present, and future of nuclear energy—one of the most promising, controversial, and misunderstood technologies of the modern age. We're traveling the world to trace the story of the atom—from ancient uranium deposits buried deep within the Earth to the newest reactor designs. The series will take listeners to Marie Curie’s perfectly preserved laboratory in France, to a new nuclear waste repository in Finland designed to withstand an ice age, to a uranium boomtown in Utah that never quite went bust, and many other important places along the atomic trail. Check out our previous episodes on nuclear energy: Make sure you're , so you'll get our nuclear series in your feed as soon as it's released in September. Closing the Gap is a production of the Alaska Center for Energy and Power at the University of Alaska Fairbanks. Our host is Gwen Holdmann. Tony Williams is our producer and engineer. Jennifer Pemberton is our writer and editor.

Listen to Gwen on the Fissionary Podcast
Gwen, Jennifer, and Tony have spent this spring and summer traveling around reporting for an exciting new season of Closing the Gap that will tell the entire history of nuclear energy over 10 episodes-- from neutron star collisions to the most by President Trump's July 4th deadline. Those episodes will be ready in a few weeks but in the meantime, we discovered a sister show of sorts called -- the podcast from the . Their hosts Mary Carpenter and Jordan Houghton sit down with experts to uncover how nuclear technology is helping make our world a better place in some unexpected ways -- not just by helping us reach climate goals but also by and to help . They're in their sixth season now, which has them globe-trotting country by country to explore exciting nuclear developments all over the world. Sound familiar? They earlier this year about what nuclear power has to offer remote Arctic places. We're that episode with you now and if you like it you should look up more episodes of Fissionary. There are new episodes every Thursday and that should keep you occupied until Closing the Gap is back this fall. Stay for our nuclear series trailer coming soon! Closing the Gap is hosted by Gwen Holdmann. Tony Williams is our producer and engineer. Jennifer Pemberton is our writer and editor. Music is from Blue Dot Sessions.

Coal-Powered Energy Research at the University of Alaska Fairbanks
02/24/2026
Coal-Powered Energy Research at the University of Alaska Fairbanks
In Fairbanks, four trainloads of coal arrive every day to power and heat the University of Alaska campus that’s known for its cutting-edge research on integrating renewable energy technologies. Building a brand new coal-fired power plant in the 21st century was, to put it mildly, a controversial decision. But believe me when I tell you—we researched the heck out of it. Today on the show, I’ll walk you through the backstory of how, when it came time to replace our campus power plant, we ticked through all our options and ended up with the newest coal plant in the country — and, some would argue, possibly the last. People: Brian Rogers, former University of Alaska Fairbanks Chancellor; Matt Titus, University of Alaska Fairbanks Utility Services Places: University of Alaska Fairbanks Technology/Concepts: utilidor, coal-fired power plant Closing the Gap is hosted by Gwen Holdmann.

The Last Coal Mine in Svalbard
Norway is determined to move away from coal and other fossil fuels entirely, but the town of Longyearbyen in the Arctic outpost of Svalbard is literally built around coal and has identified strongly as a coal town for more than 100 years. This year, the last coal mine in Longyearbyen shut down — not because they ran out of coal, but because the country is deeply committed to trying something else, even if they haven't totally figured out what that something else is yet. People: Anders Jorgensen, tour guide for Store Norske; Mons Ole Sellevold, Renewable Energy Project Manager for Store Norske Places: Longyearbyen, Svalbard, Norway Technology/Concepts: coal mining, energy transition, remote microgrid, global seed vault Closing the Gap is hosted by Gwen Holdmann.

Passive Cooling

Passive Cooling
On this podcast, we spend a lot of time talking about electricity — how to generate it, store it, and use less of it. But the truth is, the bigger share of our energy use often goes to heating and cooling — the invisible comfort systems that keep us alive in the places we choose to live. Humans are unusual that way. Most species adapt to their environment. We do the opposite — we adapt the environment to suit us. It’s how we survive in deserts and tundra, in glass towers and remote villages. Today on the show, we’re talking about passive cooling. We bring you three stories of designs that take advantage of natural temperature differences instead of using up a bunch of energy just to make something cold. People: Cloud Tsuma, guide with Sunway Safaris Places: South Africa; Doha, Qatar; Paris, France Technology/Concepts: passive cooling, termite mounds, qanat, outdoor air conditioning, evaporative cooling, district cooling Closing the Gap is hosted by Gwen Holdmann.

Trash is Treasure: Waste-to-Energy
Waste-to-energy systems kill two birds with one stone: they deal with garbage and produce power at the same time. Copenhill in Denmark has been called the coolest power plant in the world, and it’s hard to argue with that. It’s a place where you can ski down the roof, climb up the side, and then grab coffee under the smokestack — all while the building generates heat and energy for the city. At least one Alaskan community thinks Copenhagen might hold the answer for its energy and waste problems — and that’s exactly where this episode takes us. People: Jannik Koppel, Project Manager at ARC - ; Kelli Toth, Director of Solid Waste Services for the Municipality of Anchorage; Mark Spafford, Anchorage Deputy City Manager Places: Copenhagen, Denmark; Anchorage, Alaska Technology/Concepts: waste-to-energy, waste incinerator generator, solid waste recycling Closing the Gap is hosted by Gwen Holdmann.

Nuclear Energy 2.0 is (Still) Upon Us
Back in 2019, Congress directed the Department of Defense to find a site and pilot a small nuclear reactor to enhance energy resilience at military installations. That site is Eielson Air Force Base near Fairbanks, Alaska. Recently the Air Force named a developer for the reactor, so we’re revisiting the story we told back in Episode 5. In future episodes you’ll hear directly from the key people moving the project forward—both the technical lead for the Air Force and the senior commander guiding its integration on the ground. For now, we’re sharing episode 5 with you as a refresher.

Harnessing the Maelstrom: Tidal Energy
Water is 800 times denser than air and when large volumes start moving in a single direction with force and purpose, it becomes virtually unstoppable. And that force represents an opportunity to harness the power of water in a way that’s different from conventional hydropower. Instead of relying on elevation and gravity, we can capture energy directly from the flow itself. Afterall, the tides are pulled by the moon, creating a rhythm that has been in motion since long before fossil fuels were even imaginable. It’s not just renewable—it’s perpetual. Today on the show -- tidal energy in many different forms. People: , Director - Alaska Center for Energy and Power; , Alaska Center for Energy and Power; , Alaska Center for Energy and Power; Places: Saltstraumen, Norway; Tanana River Hydrokinetic Test Site, Alaska Technology/Concepts: tidal power generation, tidal barrage, hydrokinetic, in-river hydro, blade runner turbine Closing the Gap is hosted by Gwen Holdmann.

Big Dam, Little Dam: Meet the New Hydropower

Big Dam, Little Dam: Meet the New Hydropower
Hydropower comes in many forms, though most people still associate it with big dams. In the heyday of dam building, projects like Grand Coulee Dam and Boulder Dam in the American West were monumental efforts. But back then, we didn’t fully understand how dams could disrupt ecosystems; now we do, and as a result, large dams have fallen out of favor in many places. And where the U.S. was once the leader in large scale hydropower, we’re now removing more dams than we’re building. Today, the biggest obstacles to constructing new hydroelectric projects in the U.S. aren’t just environmental—they’re economic and regulatory. But hydropower is a very site-specific technology—and there are plenty of ways to make it more environmentally friendly.

Concentrated Solar Power...Can Save the World?
We started our series on solar energy at a small scale. This time, we are going big -- the Al Kharsaah Solar Plant in Qatar is one of the largest solar farms in the world. In this episode, we’re going to take a closer look at solar at scale—exploring the limits to scaling up this seemingly unlimited energy source, and the innovations underway today that could define what the solar industry looks like in the future, both in solar photovoltaics like in Qatar, as well as concentrating solar thermal.

Balcony Solar
This is the first episode in a series about solar energy, and we're starting really small. In Germany, Gwen learned about these compact personal solar kits you can install yourself -- right out of the box. There, they call it balkonkraftwerk, or balcony solar. Of course she had to buy one when she got back from Europe and try it out on her roof in Fairbanks. But is the grid ready for this kind of DIY power generation?

The Heat Beneath Our Feet: Low Temperature Geothermal
You don’t need super high temperatures to harness geothermal energy. Under the right circumstances, a much smaller thermal gradient can be used as well. If we start digging, we’re guaranteed to find heat. It’s getting that heat to the surface where we can use it without spending more energy than we can actually get out of it -- that's the tricky part. We visit South Africa, Denmark, and upstate New York to learn about the not-so-hot geothermal resource that's beneath our feet all over the world.

A Brighter History with Town Gas
Before our towns and homes were lit by electricity, we relied on something called town gas for everything from reading lights to cooking. Eventually, town gas in most places was replaced by natural gas, which burned cleaner. But the switch from town gas to natural gas was not a one to one replacement, and it was not trivial. Because town gas, unlike natural gas, is mostly hydrogen.

Turning carbon emissions into stone in Iceland
We explore two carbon capture technologies that are exploiting natural geologic processes. But the companies working on these solutions are taking those natural processes and speeding them up a bit -- giving mother nature a little extra push in order to try and slow down climate change. The first is a company called Carbfix in Iceland, which is turning carbon dioxide into stone and storing it underground. The other is using rock flour ground up by glaciers in Greenland as a carbon sink. People: Katrina Hoffman, Prince William Science Center; Ólafur Teitur Guðnason, Communications Director at Carbfix; Minik Rosing, Professor of Geology, University of Copenhagen Places: Cordova, Alaska; Reykjavik, Iceland; Greenland; Ghana; Denmark Technology/Concepts: carbon sequestration, plate techtonics, Closing the Gap is hosted by Gwen Holdmann.

Deep Under the Corn: Carbon Capture in North Dakota
Not every place has the right geologic settings for long-term carbon storage. But Alaska is one – in fact, Cook Inlet is the best tidewater location for storage on the entire west coast of North America. North Dakota is another. And for North Dakota this isn’t necessarily so much about mitigating climate change, it’s about building a new niche market to offer a service that others are willing to pay them for.

A Small Town in Alaska Considers Going Nuclear
Like much of rural Alaska, the town of Nome relies heavily on imported fuels for heating and power. The cost of heating oil here is well over $7/gallon. That’s what incentivizes a lot of Alaska communities to pursue new energy technologies, often well before they are part of the mainstream. Nome was the first community in Alaska to have a commercial solar array, and first to enter into an agreement to purchase power from a privately owned wind farm. If nuclear micro nuclear reactors are going to be feasible anywhere, Nome seems like a pretty good candidate.

Nuclear Energy 2.0 is Upon Us
The U.S. Nuclear Regulatory Commission expects to receive 25 licensing applications in the next five years for a new generation of advanced reactors. But getting any of these designs from the drawing board to reality is going to require overcoming a lot of hurdles and uncertainties. Getting any new technology to market is challenging, but that challenge is even more acute for nuclear because of the complexities and costs that it entails. In this episode we’ll look at how two U.S. nuclear projects are navigating a complicated government licensing process to develop a first-of-its-kind technology that could make a pretty big difference in our ability to decarbonize our global energy supply.

Nuclear Energy: How Safe is Safe Enough?
Nuclear power is different from other energy sources. When we talk about new nuclear projects, it can still bring up strong and sometimes emotional reactions for people -- more so than with other sources of energy, and those opinions are much more divided across the political spectrum than any other technology. How did public perception change as nuclear moved from a technology of war to the energy solution of the future? And when it comes to energy technologies, or really any technology, how safe is safe enough?

Geothermal heating: from Idaho to Iceland
Iceland is a powerhouse when it comes to harnessing the heat and the energy that’s pouring up through the tectonic crack that runs diagonally across the island. Icelanders originally got the idea for geothermal district heating from turn-of-the-century Idaho. But since then, the small nation managed to gather best practices from places like Boise, and then improve on them. And now they have the most concentrated know-how of geothermal energy in the world, and they market and export that expertise globally.
