Energy storage. We could already produce all the power we need and more using solar power, the problem is that we can’t store it in an efficient energy dense form. The word efficient there is doing some heavy lifting. It needs be comparable or better than our methods today in terms of cost, safety, energy density, climate impact. If we could solve energy storage, it’d change society and technology dramatically.
Cultured Meat. Without relying on any major breakthroughs, a price competitive with “traditional” meat is feasible with a few rather reasonable and conservative assumptions and developments. Dropping cows as meat source globally alone might be sufficient to slow down further climate change significantly.

Love this answer! I wish the EU could move it in as an EU agency.
Nuclear fusion, right? That’s got to be the big one.
I’m sure you’ll get a bunch of respectable answers, but keep in mind that secretly, everyone is actually thinking sex robots.
Which is an application that generative AI is important for, ironically.
And if they were not, they should have been.
Climate change
I would specifically pick Fusion research.
Kind of a two-fer right there. Without “AI” sucking up so much power, we’d already be better off climate-wise.
True, but still only marginally.
I think concrete is still king.
Trains.
I like trains!
