Decarbonize Weekly DD010 — Green Steel: Boden Proves It Works

📺 Decarbonize Deep Dive 010 | ~22 min DEEP DIVE: The 2026 Green Steel Inflection — CBAM, Boden, and the Economics That Finally Work On January 1, 2026, the EU's Carbon Border Adjustment Mechanism entered full enforcement. On the same continent, Stegra's Boden plant in northern Sweden is entering commissioning — the world's first full-commercial-scale DRI facility running on green hydrogen, backed by €3.5 billion in capital and offtake contracts from Volkswagen, Mercedes, and BMW. These two events — CBAM and Boden — are the first time that green steel has had both a proven technology at commercial scale and a market mechanism that changes the competitive economics. For twenty years, the decarbonization pathway for steel was clear in theory and unbuilt in practice. 2026 is when that changes. Steel is responsible for 7–9% of global CO₂ — roughly 2.3 billion tonnes per year. The blast furnace has been the dominant technology for 150 years. The chemistry requires a reductant, and that reductant has always been coal. Replacing it with green hydrogen — and the liquid steel with a near-zero-carbon product — is what Boden is now proving at commercial scale. Key topics: • Why steelmaking is structurally hard to decarbonize — the chemistry problem, not the combustion problem • How DRI-EAF (Direct Reduced Iron — Electric Arc Furnace) replaces the blast furnace, step by step • What Stegra Boden actually is — scale, H₂ volumes, renewable power supply, steel grades, and what it answers • CBAM full enforcement: what €70–140/tonne on imported high-carbon steel does to the competitive math • The green hydrogen cost equation — 55 kg H₂/tonne DRI, and why €2–3/kg is the break-even threshold • Why automaker offtake contracts at €100–300/t premium are what makes Stegra financeable — buyer pull, not spot competition • The blast furnace majority — why 70% of global steel is still BF-BOF and what it takes to transition China's fleet • Boston Metal's MOE as the alternative pathway — direct iron oxide electrolysis, no H₂ supply chain required • The scale reality: optimistic 2030 scenario is 50–80 Mt of green steel — still less than 4% of global production • Three things to watch through end of 2026: Boden ramp-up yields, CBAM first full-year certificate submissions, EU ETS Investment Booster allocations The Boden commissioning is the event. The CBAM enforcement is the market mechanism. 2026 is when the answer to "can green steel actually work?" stops being theoretical. --- 🔗 Website: decarbonizeweekly.com 📧 Contact: hello@decarbonizeweekly.com 🎧 Also on Spotify: search 'Decarbonize Weekly' #GreenSteel #CBAM #DRI #EAF #Stegra #GreenHydrogen #SteelDecarbonization #IndustrialDecarbonization #EUClimate #CarbonBorderAdjustment #Decarbonization #ClimatePolicy #HydrogenEconomy #BotonMetal #MOE #BlastFurnace

Decarbonize Weekly DD009 — The Transition's Oldest Accelerant

📺 Decarbonize Deep Dive 009 | ~22 min DEEP DIVE: The Largest Oil Shock in History — and the First With a Real Off-Ramp The Strait of Hormuz has been closed since 28 February 2026. Eleven weeks in, the IEA calls it the largest oil supply disruption in the history of the global oil market — more than 10 million barrels a day removed, roughly twice the size of the 1973 and 1979 shocks. Brent peaked near $126 in April and sits around $100 in mid-May, up about 58% year-to-date. Most coverage asks one question: how high do prices go? Decarbonize Weekly asks the one that matters more — does an oil shock this size accelerate the energy transition, or stall it? History says oil shocks accelerate structural change. What makes 2026 different is that, for the first time, the alternatives — EVs, heat pumps, grid storage, electrified freight, sustainable fuels — are mature enough to absorb the demand a shock displaces. But maturity is not destiny: the same shock that pulls demand toward electricity also raises the cost of the capital needed to build the electric supply. Which force wins is a policy choice, not a market outcome. Key topics: • The 1970s template — how the 1973 and 1979 shocks reshaped energy policy, and why the structural responses (efficiency standards, building codes, the strategic petroleum reserve) outlasted the price spike by decades • Demand destruction vs. demand substitution — why 2026 is the first oil shock where switching fuels, not just using less, is a large and available channel • The accelerant in the data — European BEV sales +29.4% in Q1 2026, EVs roughly 1 in 4 new cars sold globally, solar leading global energy demand growth for the first time • The other half of the story — why the same shock starves the transition of capital: higher-for-longer interest rates, fossil supply as the highest-return trade, and the affordability ceiling on transition politics • The tie-breaker — why locking in demand-side structural change while the price signal is doing the persuading is what made 1973 matter for decades • The aviation exception — SAF at 0.8% of jet fuel, no European e-SAF project at final investment decision, and why the shock makes the gap more visible without making it smaller • The transatlantic split — a tightening EU with the machinery to convert a price signal into policy vs. a deregulating US relying on the price signal alone • The realistic 2026 outlook — base, upside and downside cases, and the four signals that will tell you which one is unfolding The technology question is settled. Whether 2026 becomes the transition's inflection point or a missed decade turns entirely on capital allocation — and that is a choice being made right now. --- 🔗 Website: decarbonizeweekly.com 📧 Contact: hello@decarbonizeweekly.com 🎧 Also on Spotify: search 'Decarbonize Weekly' #OilShock #EnergyTransition #StraitOfHormuz #OilCrisis #BrentCrude #Electrification #EVs #SAF #EnergySecurity #1973OilCrisis #RenewableEnergy #CleanEnergy #Decarbonization #EnergyPolicy #ClimateTech #DecarbonizeWeekly

Decarbonize Weekly DD008 — Why PJM Chose Gas for AI

📺 Decarbonize Deep Dive 008 | ~22 min DEEP DIVE: The Gas Verdict — PJM Just Decided How AI Will Be Powered On April 29, 2026, PJM Interconnection — the largest grid operator in North America — announced the results of the first cycle of its reformed interconnection queue. After four years of effective closure, 811 generation projects representing 220 gigawatts entered the queue. The composition is the story: • 106 GW natural gas (48%) • 67 GW battery storage (30%) • 18 GW nuclear (8%) • 15 GW stand-alone solar (7%) • 9 GW solar-storage hybrid (4%) • 5 GW wind (2%) Combined with the parallel Texas behind-the-meter buildout — 58 GW of gas in planning, half of it dedicated to data centers on private grids that bypass the public grid entirely — this is the verdict on how American AI infrastructure will be powered through 2032. Not with geothermal. Not with small modular reactors. Not with renewables-plus-storage. With natural gas. Key topics: • The PJM Cycle 1 numbers and what they mean — first reformed queue with first-ready, first-served filtering • Why gas wins on the five variables: speed of build, capacity factor, capital intensity, site control, federal regulatory environment • Texas behind-the-meter — Pacifico's 7.7 GW GW Ranch, the Lancium / Crusoe / Stargate clusters, and the private-grid pattern • Why the 67 GW of storage in the queue is mostly a complement to gas, not a replacement • Why the 18 GW of nuclear is smaller than it sounds — uprates, restarts, aspirational SMR pipeline • The state climate plan implications for Maryland, Virginia, New Jersey, Illinois — RPS targets calibrated against assumptions Cycle 1 has just broken • The federal regulatory dismantling that locked the gas verdict — 2025 budget reconciliation, EPA 111(b) rollback, 45V cancellation, PTC/ITC acceleration removed • The transatlantic split — EU Hydrogen Bank's €0.44/kg auction announced May 7 vs. US 45V cancellation • Realistic 2026-2032 buildout projection — gas at 80-110 GW, storage 50-70 GW, solar 30-45 GW, then a sharp drop • What this means for 2030 NDC math — roughly 100 Mt/yr of CO2 added to the power sector from AI load alone • Three things to watch through end of 2026: PJM Cycle 2 composition, Texas BTM regulation, Maryland PSC response The clean firm power story (geothermal, SMR, nuclear restarts) is real but second-tier in the 2026-2032 buildout window. AI training capacity needs to be online before any of those scale. PJM Cycle 1 is the math made visible. --- 🔗 Website: decarbonizeweekly.com 📧 Contact: hello@decarbonizeweekly.com 🎧 Also on Spotify: search 'Decarbonize Weekly' #AIDataCenters #PJM #InterconnectionQueue #DataCenterPower #NaturalGas #BehindTheMeter #Decarbonization #CleanEnergy #USPowerGrid #GridReliability #ClimatePolicy #IRA #45V #StateRPS #ClimateTech #DecarbonizeWeekly

Decarbonize Weekly DD007 — The Green Hydrogen Reset: Why 60 Projects Died and What Survives

📺 Decarbonize Deep Dive 007 | ~22 min DEEP DIVE: The Quiet Reset That's Defining the Real Hydrogen Economy Between mid-2024 and April 2026, the green hydrogen industry experienced its first real correction. Companies cancelled close to 60 major projects in 2025 alone — more than 4.9 million tonnes per year of would-have-been capacity. BP exited Australia, Oman, and the UK. Air Products halted three US projects. ArcelorMittal walked away despite €1.3B in committed subsidies. Lhyfe suspended a >100 MW project in April 2026. But this is not the death of clean hydrogen. It's the death of speculative clean hydrogen. While the export mega-projects collapsed, FIDs in 2025 actually grew ~20% — on a different shape of project. Key topics covered: • The 60-project cancellation wave: who died and why • The 4 economic gates every hydrogen project must clear (most failed at "bankable offtake") • Why the cost curve disappointed: stack cost-down, balance-of-plant inflation, capacity factor revisions • The survivor pattern — Stegra (€1.4B closed April 2026), Plug Power's Quebec deal, Topsoe SOEC, Sunfire alkaline • The EU Hydrogen Mechanism (April 30, 2026): what it is and why it might actually work • Hy24 quadrupling its Enagás Renovable stake — the PE survivor signal • Why captive industrial use cases (steel, ammonia, methanol, refining) quietly worked while transport and heat didn't • 45V regulatory turbulence, additionality, time-matching: the policy story that broke US economics • Realistic 2030 outlook: 25-40 GW operational vs the 150 GW announced pipeline • 5 things to watch in 2026-2027 The hydrogen industry that exists in 2030 will be smaller than the 2022 forecasts suggested but materially more bankable. It is anchored to captive industrial demand, modular sizing, sovereign-backed offtake, and customers who absorb the green premium through their own product price. That is a real, durable, financeable industry — and it's the one that will actually decarbonize hard-to-abate sectors in time to matter. --- 🔗 Website: decarbonizeweekly.com 📧 Contact: hello@decarbonizeweekly.com 🎧 Also on Spotify: search 'Decarbonize Weekly' #GreenHydrogen #HydrogenEconomy #ProjectCancellations #BankableOfftake #Stegra #PlugPower #EUHydrogenMechanism #45V #ClimateTech #IndustrialDecarbonization #Decarbonization #DecarbonizeWeekly
