In December 2022, scientists at the National Ignition Facility achieved a landmark nuclear fusion result: a reaction that produced more energy than the laser pulse used to start it. It made headlines globally, but the caveats came quickly. Overall system energy use was still far higher, and commercial viability remains decades away. It was a real breakthrough, but also a reminder of how far the engineering still has to go.
That gap between scientific progress and commercial reality is a defining feature of the energy transition today. While solar, wind, and batteries are scaling rapidly and doing most of the heavy lifting, the International Energy Agency estimates that nearly half of the emissions reductions needed for net zero will depend on technologies still at demonstration stage or earlier. This raises the key question: which “wild card” technologies could help close that gap?We take a look.
