Fusion. The current pace of research is extremely slow. The Wendelstein 7-X, one of the most advanced fusion experiments, was designed on super computers almost 30 years ago, since which huge advances have been made in materials and simulations. Also fusion has always had an uphill battle against entrenched petrochemical interests, that may change in the coming decades.
