There are different fusion reactor designs, that are currently investigated. For the Tokamak, where the plasma is confined by magnets in a donut shaped vessel, they are currently building a prototype in France called ITER. With the results of this, they want to build the first fusion reactor DEMO, that actually produces energy.

The headline from the current experiment was from a facility, where the plasma is confined by lasers. This technique was not on the original roadmap of fusion plants, so it's quite surprising, that they already got that far. Unfortunately, it scales really badly, because they use special containers with hydrogen inside as fuel and you can't really make those bigger. As far as I know, they already use state of the art lasers already, so that's another bottleneck there.
