The Last Coal Mine in Svalbard

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

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.

A Nuclear Reactor for Alaska's F-35s

The multi-million dollar fighter jets that roar over the local tennis court where I coach the high school team is a daily reminder that Fairbanks is home to one of the most strategically important Air Force bases in the world. And now, Eielson Air Force Base is about to make history on a very different front — testing a first-of-its-kind nuclear microreactor. People: Colonel Michael Mullin, Deputy Wing Commander, Eielson Air Force Base; Nancy Balkus, Deputy Assistant Secretary of the Air Force for Infrastructure, Energy and Environment Places: Fairbanks, Alaska; Eielson Air Force Base Technology/Concepts: nuclear microreactor, small modular nuclear power, Arctic security, cold weather combat training Closing the Gap is hosted by Gwen Holdmann, edited by Jennifer Pemberton, and produced by Tony Williams.
