Vertical’s Farnborough flights demonstrated real engineering progress. Five years after listing, outside capital still funds the path toward certification and an unproven passenger market.
Vertical Aerospace’s July appearance at the Farnborough International Airshow was a real engineering milestone. The company publicly demonstrated piloted transition between vertical and wingborne flight, something a powered-lift aircraft has to do safely and repeatedly before certification can advance. Vertical then flew on successive days in front of a large … [continued]
Electric freight rail is established technology. The unresolved North American question is where electrification pays first, not whether electric traction works.
Direct electric freight rail is not speculative technology. It already operates across enormous railway systems, moves very heavy freight and works in difficult climates. The interesting North American question is therefore not whether electric freight rail can work, but where catenary should go first, where batteries or dual-mode locomotives make … [continued]
Electrolyzer stacks are manufactured, but hydrogen plants are built. Much of the apparent learning challenge—and most of the project cost—lives outside the stack factory.
Hydrogen cost forecasts often borrow one of the clean-energy transition’s most useful empirical tools: the experience curve. If a technology has historically fallen by a given percentage in cost every time cumulative deployment doubles, analysts can estimate how many doublings lie ahead and compound the learning rate into a future … [continued]
Hydrogen’s detour persisted because incumbent assets, skills and institutions had reasons to keep the molecule economy politically viable after the economics weakened.
In 2023, a senior executive responsible for decarbonizing a major transportation company asked me, with some exasperation, what drove the “madness on hydrogen.” Hydrogen proposals kept arriving for applications where the energy balance and economics looked dreadful. That conversation became What Drives This Madness On Hydrogen?, an attempt to explain … [continued]
Hydrogen and electrification occupy surprisingly similar amounts of attention despite radically different levels of physical deployment.
Hydrogen occupies an unusually large share of the energy-transition information stream for the amount of physical deployment behind it. Fuel-cell trucks, buses, trains, ships, storage projects, demonstrations and records recur through corporate releases, government announcements, trade publications and mainstream reporting, creating the impression that hydrogen remains a substantial parallel pathway … [continued]
The next evolution XPENG’s physical AI is beginning to emerge. Announcements over the past week indicate major developments for IRON humanoid robot, VLA 2.0 intelligent driving and the business overall. Many of these developments have not yet been realized in revenue and profits, but are poised to drive the rapidly expanding technology company to the next level in their development.
Even the strongest apparent dual-product customer cannot absorb the mass balance: a large hydrogen-DRI steelworks could still leave roughly 80–90% of thermolysis graphite needing other markets.
Methane thermolysis has one of the cleaner propositions in the hydrogen space. The process is also commonly called methane pyrolysis, but I prefer thermolysis. An engineer and founder working in the field pointed out to me that the useful distinction is straightforward: it is heat, not flames, doing the work. … [continued]
Carney’s industrial strategy is strongest where government builds shared productive capacity and leaves firms and technologies to compete over how it is used.
Mark Carney’s industrial-policy agenda has reopened a debate Canada never really escaped: when should government build, finance or shape productive capacity, and when should it leave the result to markets? The proposed C$25 billion Canada Strong Fund makes the question concrete because Ottawa would borrow to capitalize an investment vehicle … [continued]
Heart Aerospace’s X1 represents the less glamorous but more consequential aviation transition: electrifying an existing market rather than inventing a new one.
Heart Aerospace’s X1 demonstrator flew for 27 minutes on August 12 from Plattsburgh International Airport, powered entirely by batteries. The aircraft has a 106-foot wingspan, weighed more than 25,000 pounds at takeoff and drew more than a megawatt at peak. Heart calls it the largest battery-electric aircraft ever flown. The … [continued]
Poland succeeded in creating hydrogen-bus demand, but Polenergia still backed away from the local green-hydrogen supply intended to serve it.
Poland did something hydrogen advocates have spent years saying governments need to do: it created real demand. Public subsidies helped put hydrogen buses into Polish cities, refueling infrastructure received support, and renewable-hydrogen projects were offered public money as well. By April 2026, Poland had 153 hydrogen buses registered, 140 already … [continued]
