The COP31 target for electricity to reach 35% of final energy demand by 2035 is useful. But that's not useful energy. Thanks to @mliebreich.bsky.social for pointing out my own confusion on the point? Electrification targets need a useful-energy translation. briefing.tfie.io/p/stop-steer...

Agrivoltaics works where shade does farm work. The test is not whether crops can survive near panels. It is whether panels provide agricultural function: shade, protection, water resilience, grazing value, machinery-compatible land sharing or durable farm income. briefing.tfie.io/p/agrivoltai...

UK's HyHaul hydrogen corridor failure is a warning, not an outlier. Hydrogen transport needs vehicles plus a parallel fuel system: production, compression, storage, dispensing, safety, maintenance and utilization. Batteries scale depot by depot and route by route. briefing.tfie.io/p/hyhaul-hyd...

Fabric first is often good building practice. It is not always climate-first sequencing. Insulation helps, but making deep retrofit a prerequisite for heat pumps can delay the bigger emissions cut: stopping gas combustion for heat. briefing.tfie.io/p/octopus-he...

Grid storage is not one problem. Fast response, daily shifting, multi-day balancing, transmission relief, demand flexibility and rare reserve events are different jobs. Once separated, hydrogen shrinks to a narrow tail case. briefing.tfie.io/p/grid-stora...

Hydrogen demand shrinks when it is counted properly. Refining falls with oil demand. Fertilizer moderates. Methanol and process chemistry remain. Most transport, heating, aviation, shipping and grid-storage claims fail against electrification or better options. briefing.tfie.io/p/hydrogen-d...

Brimstone’s cement story is really a minerals-refinery story. Cement, SCM and alumina first. Aluminum, iron, magnesium, titanium and other minerals later. That makes the opportunity larger, but also raises the FOAK evidence burden. briefing.tfie.io/p/brimstone-...

China’s electric heavy-truck plan is not just a vehicle target. It is a freight-system target: corridors, depots, charging, battery swapping, grid capacity and logistics use cases. briefing.tfie.io/p/china-elec...

A river turbine can generate electricity. The harder claim is cheap dependable power after anchoring, floods, debris, maintenance, interconnection, permitting and alternatives are counted. River-current power is real. Cheap baseload is still unproven. briefing.tfie.io/p/river-curr...

Cement decarbonization is not one magic binder. The pathway is less residual Portland: better design, lower clinker, regional substitutes, mass timber where it works, recycling and selective CCS. Subscribe and read the TFIE Briefing piece: briefing.tfie.io/p/cement-dec...

Climate-tech claims need a cheap red-flag pass before they get money or policy support: denominator, evidence quality, system boundary, alternatives, cost stack, adoption and timing. Read the TFIE Briefing piece: briefing.tfie.io/p/climate-te...

Hawaiʻi is an island-energy systems test: no continental grid, high fuel exposure, real land limits and cooling demand. The practical path is local clean electricity, storage, flexibility, efficient cooling and careful reserves. Read the TFIE roadmap: briefing.tfie.io/p/hawaii-cle...

Port decarbonization starts with equipment, drayage, charging, shore power and grid capacity. Fuel choices come later for the hardest vessel routes. Subscribe for the TFIE Strategy roadmap: briefing.tfie.io/p/port-decar...

Follow for long-form energy transition analysis with a low tolerance for hype. Electricity expands. Molecules retreat. China scales. FOAK risk stays real. Announcements are not deployment. TFIE Strategy Briefing: briefing.tfie.io

Geothermal is strongest in heat, district systems, ground-source heat pumps and good hydrothermal resources. The hype sits in deep electricity claims that still have to beat drilling risk, project finance and improving alternatives. briefing.tfie.io/p/geothermal...

Local transition curves are jagged. The global curve is smoother because countries, firms, shocks, supply chains and industrial strategies move at once. Don’t confuse the country making the most noise with the world. briefing.tfie.io/p/geopolitic...

Electricity wins because it breaks fossil fuel chains. A motor, heat pump or furnace doesn’t need a permanent fuel pathway; it needs useful energy through shared infrastructure that can keep decarbonizing. briefing.tfie.io/p/electricit...

Cement is often framed as a kiln-and-carbon-capture problem. The bigger question is how much cement the system needs by 2100 after demand, clinker, substitutes, electrified heat and China’s denominator change. briefing.tfie.io/p/cement-tra...

Constraints are real, but they are not usually static. Grid queues, minerals, permitting and supply chains change prices, investment, substitution and policy. Long-range transition analysis has to model the response, not freeze today’s bottleneck. briefing.tfie.io/p/constraint...

Boston Metal’s evidence points more to selected critical-metals recovery than proven green steel. That may be a credible first market for MOE, but bulk green iron still has a much larger evidence burden. briefing.tfie.io/p/boston-met...

Mass timber is not a boutique architecture story. For Canada, the question is whether forestry, housing demand, factories, codes, insurance and procurement can become an industrial system. briefing.tfie.io/p/mass-timbe...

Critical minerals are not just a mining problem. They are an industrial strategy problem. The leverage sits in processing, manufacturing, recycling and trusted partners, not mineral independence. briefing.tfie.io/p/critical-m...

Transition claims have to survive three filters: the science and cost stack, the alternatives after the full chain is counted, and adoption reality. That is the discipline many hydrogen, CCS, storage, fuel and FOAK claims skip. briefing.tfie.io/p/solutions-...

Molecules do not disappear in the transition, but their market shrinks to real jobs: aviation, some shipping, feedstocks, specific industrial niches and resilience cases. Most heat, motion and storage goes direct-electric first. briefing.tfie.io/p/molecules-...

Growth no longer guarantees fuel growth. Population, China’s first-build slowdown, electrification and efficiency are breaking the old GDP-to-fossil-fuel link. A TFIE Strategy WorldView piece on why many fuel forecasts are still using the wrong denominator. briefing.tfie.io/p/growth-no-...

Shipping’s fuel transition starts with less fuel, not better molecules. Fossil cargo declines, raw iron ore is exposed, short routes electrify, and scarce liquids belong only where ships still need fuel. Read the Briefing analysis: briefing.tfie.io/p/shipping-f...

Steel decarbonization is a route problem, not a hydrogen demand story. Scrap-EAF does most of the long-term work, clean primary iron stays bounded, and hydrogen has to compete inside that remainder. briefing.tfie.io/p/steel-rout...

France is treating electrification as energy security and industrial policy. Right direction. Suspicious deadline. Grids, heat pumps, EVs and industry decide whether it becomes strategy or slogan. briefing.tfie.io/p/france-ele...

Air lubrication can reduce fuel burn on the right ships, but it is an efficiency wedge, not a shipping transition strategy. The heavy lifting remains electrification where possible and sustainable fuels where necessary. Subscribe for more transition analysis. briefing.tfie.io/p/air-lubric...

Steel decarbonization is not mainly a hydrogen story. The denominator is demand, scrap growth, EAFs, construction slowdown, material substitution and how much new primary iron is actually needed. briefing.tfie.io/p/steel-2100...

Hydrogen buses work. The problem is the operating system: fuel cost, depot infrastructure, uptime, maintenance, warranties and repeat procurement. For transit agencies, hydrogen is a procurement risk premium, not a shortcut. briefing.tfie.io/p/hydrogen-b...

Belgium’s hydrogen refuelling story has a denominator problem. Atawey’s 3 new stations claim +7,000 kg/day capacity. H2Benelux’s whole trial was 8 stations and 80 vehicles across Benelux. That is not a trucking market. Subscribe for the denominator work: briefing.tfie.io/p/belgium-hy...

A pilot is not proof of scale. A grant is not proof of economics. An offtake agreement is not proof of market demand. Counterinduction is the habit of asking whether the evidence points the other way. I use it constantly in climate-tech diligence. briefing.tfie.io/p/counterind...

China has made underwater data centers commercially real. Seawater helps with cooling, but grid, cables, maintenance, permitting, security, and lifecycle costs still matter. Read the TFIE Strategy Briefing and subscribe: briefing.tfie.io/p/underwater...

Africa officially added 4.5 GW of solar in 2025, but imported 18.2 GW of modules. That gap matters. The boom may be showing up first in mines, telecoms, farms, mini-grids and diesel displacement before official grid stats catch up. briefing.tfie.io/p/africa-sol...

Hydrostor’s Ontario storage plan may work, but the benchmark has changed. A deep underground, 500 MW/4 GWh cavern project has to beat modular BESS on cost, risk, efficiency and delivery, not just claim long-duration virtue. cleantechnica.com/2026/05/20/h...

Hormuz is not just an oil and LNG chokepoint. Its sulfur shock previews a decarbonized future where cheap fossil byproduct sulfur shrinks, phosphate fertilizer and critical minerals face higher acid costs, and supply chains need sober redesign.

Poland bought hydrogen buses with big subsidies. Then fuel bills, station losses, supply failures and weak lifecycle accounting arrived. The lesson is dull but important: use scarce green hydrogen where hydrogen is already needed, and electrify buses directly. cleantechnica.com/2026/05/19/p...

Toyota’s hydrogen truck deal is another controlled deployment, not real market pull. The pattern is clear: Toyota keeps supplying, funding, fueling and backstopping a market that still fails the basic tests on cost, customers and infrastructure. cleantechnica.com/2026/05/18/t...

Solar and farming can share land, but agrivoltaics is not one thing. China leads at scale, while US projects are mostly grazing, pollinators, and trials. The real test is farm-first design, water stress, machinery access, and honest dual-use metrics. cleantechnica.com/2026/05/16/s...

Energy models are useful, but when they smooth nuclear and hydrogen delivery while underseeing renewables, storage and grid flexibility, policy gets distorted. Imagination has to be disciplined by evidence. cleantechnica.com/2026/05/16/n...

The Jones Act waiver didn’t solve fuel prices or repeal cabotage. It exposed the real problem: protected scarcity. U.S. maritime security needs ships, crews, yards and clean vessel deployment at scale, not a law mistaken for strategy. cleantechnica.com/2026/05/15/j...
