What If Fusion Power Arrived in 2035?

The geopolitics moved faster than the engineering, and in stranger directions than most 2035-era forecasting anticipated. Within two years, fusion research — which had been one of the rare genuinely collaborative international scientific endeavors, with ITER itself a joint project of thirty-five countries — began fracturing along familiar lines, as the major powers each concluded, more or less simultaneously, that whoever commercialized the technology first would hold a strategic advantage too significant to share.

China's state fusion program, which had been running a parallel track to ITER with its own experimental reactor, announced an accelerated commercialization timeline in 2037 that most Western energy analysts considered implausibly aggressive. It was not entirely implausible. China's first grid-connected fusion facility came online in late 2040, eighteen months ahead of South Korea's, built with a state-directed urgency that democratic funding cycles elsewhere struggled to match.

I spent most of 2038 reporting on what several of my sources, off the record, were calling "the second space race" — a framing that irritated the scientists I interviewed, who pointed out, correctly, that a space race produces flags on a rock, while a fusion race produces something every nation on earth actually needs. The framing stuck anyway, because it captured something true about the mood, if not the stakes: a sense that whoever won this particular technological contest would hold leverage over everyone who hadn't.
