The article probably explains it but I think it's important to mention every time. It's not the total energy put into the experiment (charging up the equipment etc); It's the energy put into the collision.

It's an important measure but it must also produce more than is put into the entire system, and even more than that to be financially viable and cover costs.

Tl;DR: Still not viable for production.

Extra paraphrasing:
Further testing needs funding and the construction of specialized facilities as the current ones have already reached their limits.
Too late to solve climate crisis with it. Current alternatives are recommended instead.
