    The Week LNG Became a Target

    13/03/2026 | 1h 15 mins.
    The Iranian drone strike on Qatar’s Ras Laffan industrial complex has sent shockwaves through global energy markets, triggering force majeure on 20 percent of the world’s LNG supply and closing the Strait of Hormuz to commercial shipping. To understand what just happened and what comes next, Decouple is joined by Stephen Stapczynski, Bloomberg’s leading LNG correspondent and one of the few journalists who has spent years tracking the shadow fleets, supply chains, and geopolitics that sit behind the world’s fastest-growing fossil fuel market.
    This conversation traces how Qatar came to sit atop the world’s most consequential gas reservoir, why Iran was never able to monetize its side of the same field, and how the shale revolution gave Washington the geopolitical freedom to let this crisis unfold. Stephen discusses the Arctic Metagas, the first LNG carrier ever successfully attacked, and what its destruction in the Mediterranean signals about a world in which the affordable, reliable LNG that was supposed to be the bridge fuel for the developing world was always premised on freedom of navigation holding.

    Nuclear Fuel: The Most Sophisticated Industrial Product You've Never Learned About

    26/02/2026 | 1h 20 mins.
    Nuclear fuel is nothing like the coal or gas it replaces. Where fossil fuels are destroyed in combustion, nuclear fuel must survive years of continuous fission inside a reactor and come out the other end looking almost exactly as it went in. In this episode, fuel engineer Michael Seely breaks down how uranium dioxide pellets are made, why the fuel rod is one of the most sophisticated manufactured objects in the world, and how an industry that once ran more than half its fleet on leaking fuel pins methodically engineered its way to near-zero failure rates by 2010.
    We also get into enrichment economics, the bespoke nature of reactor fuel design, the post-Fukushima push toward accident-tolerant and higher-burnup LEU Plus fuel, and why high-assay low-enriched uranium (HALEU), the feedstock required by most advanced reactor concepts, requires 40 kilograms of natural uranium and six times the separative work of conventional fuel just to produce a single kilogram. If you want to understand why nuclear plants are built the way they are, why the water cooled reactor won, and what the fuel supply chain challenge really means for the advanced reactor industry, this is the episode to start with.

    The Most Boring Path to 10 Gigawatts: Why Nuclear Uprates Matter Right Now

    17/02/2026 | 1h 5 mins.
    For two decades the nuclear conversation has revolved around new builds, advanced reactors, and megaproject risk. Meanwhile, forty Westinghouse pressurized water reactors continue operating at roughly the same thermal output they were commissioned at decades ago, leaving six to ten gigawatts of potential capacity sitting inside existing plants. In this episode, I speak with Robb Stewart and James Krellenstein of Alva Energy about why power uprates may be the fastest and most capital efficient way to expand nuclear generation in the United States. Rather than chasing first of a kind reactor designs, they argue that modern steam generator technology, improved thermal hydraulic modeling, and standardized secondary side upgrades can unlock the equivalent of twenty to thirty 300 megawatt small modular reactors within three to five years.
    We examine why boiling water reactors captured most historical uprates while pressurized water reactors remained largely untouched, how balance of plant constraints rather than reactor physics often limit output, and why diverting additional steam to a separate turbine island changes both risk and economics. With hyperscalers willing to pay premium prices for reliable, low carbon power, incremental nuclear megawatts now carry real market value. The question is whether the industry can prioritize disciplined industrial execution over novelty and finally harvest the gigawatts hiding in plain sight.

    AI with Chinese Characteristics

    12/02/2026 | 1h 6 mins.
    In this episode of Decouple, Chris sits down with Kyle Chan of the High Capacity Substack to unpack what “AI with Chinese characteristics” actually means. Rather than framing artificial intelligence as a simple US–China race to AGI, they explore how each country is building AI inside very different institutional systems. The conversation covers DeepSeek, compute constraints, quantization, and the surprising reality that many Chinese AI labs operate with far less capital than their American counterparts while still publishing at the frontier.
    They dig into China’s AI enabling stack, from universities and state-backed labs to energy buildout and the Western Data, Eastern Compute strategy, and examine how AI is being embedded into manufacturing, logistics, grid management, and public services as a tool of state capacity. The discussion also tackles regulatory differences, CCP oversight, training data controls, and the disciplining of China’s tech sector, alongside contrasts with US AI development shaped by venture capital, platform economics, and liability management. This is a deep dive into how institutions shape technology, and why the real story may not be who wins the race, but how AI is absorbed into two very different political economies.
