Funding patterns across climate tech—fusion, heat pumps, hydrogen—and the limited public disclosure of costs and performance data.
NOX Energy raised 3 million euros in seed funding for software that lets energy suppliers run home heat pumps on power prices. Rival Axle Energy claims 30 times as many devices, so the round is a bet that suppliers will pay a small, focused player.

The company left stealth on Wednesday with a plan to attach supercritical CO2 units to the simple-cycle turbines data centers chose, making electricity from exhaust heat those turbines now throw away.
Reality
Kanin will finance, build and operate the plants itself and sell the power to industrial hosts, against a portfolio of about 50MW already running or under construction. The turbine design is four decades old.
Reality
Xcimer took investment from RTX Ventures and Pacific Fusion signed an agreement with the NNSA. TechCrunch's reporting shows defense interest landing on machines that already exist, with both plant programs still running.
Reality
Electrolyzers and carbon-captured gas have both stalled on cost. The third option, digging hydrogen out of iron-rich rock, is now funded at scale but still unproven as a resource.
Reality
A utility foundation with a $20 million commitment reports $555 million in follow-on capital, a multiple National Grid's $500 million venture arm has not matched. The lesson is distribution, not dollars.

A decade of borehole data from Ontario's Kidd Creek mine puts about 140 tonnes of hydrogen a year escaping unused. That is roughly where the evidence stands.
