The cheapest hydrogen on Earth comes from machines that only run when power is nearly free. Almost no one does this: matching the intermittency of solar means constantly ramping the electrolyzer, which wears it out fast — the opposite of the incumbent model of investing into exquisite machines conserved at steady state. Lavoit’s intelligence changes the paradigm, because intelligence and actuation can finally run this control problem at the speed it demands: tracking power prices, ramping the stack, and managing degradation all at once, in real time. The winning point sits where near-free power, hardware wear, and output meet, and Lavoit rides it, turning surplus power into cheap, plentiful hydrogen.

The market for fossil-derived hydrogen is well over $500bn. The category is in a hype winter, but the cooling is exactly what makes the entry cheap — talent and hardware are on sale while Nils builds. Every hour Lavoit's electrolyzers run, they log how the hardware behaves and sharpen the model that decides when to run the next hour. The same data shows how the different stages of the value chain fit together — renewables, hardware, distribution — and the company earns the right to verticalize and coordinate an increasingly complex industrial system, one link at a time.

Nils Samrud has been obsessed with hydrogen since he was twelve. After five years building electrolyzers in his grandfather’s chicken coop, he realized that however much he improved the physical design, hydrogen is a full systems-control problem, not just a hardware one. He taught himself from journal papers after a scientist told him to come back with a degree, and wrote a 200-page manifesto on hydrogen systems at sixteen.

As the price of power keeps falling, the only question left is what to do with the electrons that no one can use. Lavoit is the answer: a machine that turns surplus energy into stored potential. That liquid possibility can be deployed on tap to produce the building blocks of the physical world—fuels, fertilisers, and metals — all from sun, water, and air.
