Climate infrastructure

Let’s get physical

Last updated: 30 Mar 2023

Market 101

If scaling a startup is already tough, it’s even harder when it’s not selling pocket-friendly, shiny software with a clear exit path. Climate infrastructure startups – which strive to speed up mass adoption of hardware-bound sustainable tech – have mostly worked in the shadows so far, designing battery gigafactories and tech-enabling plants to back Europe’s climate goals. But while their ideas are great, they don’t come cheap.

Climate infrastructure startups can range anywhere from battery and nuclear fusion plants to hydrogen and carbon capture facilities, but they all have two things in common: they build big physical stuff and burn a lot of cash in the process. Add the (currently) moderate risk/reward ratio, and it becomes clearer why VCs might get the chills when asked to invest multi-million-dollar cheques into relatively untested tech. Or they may just lack the expertise, and don’t fancy a Britishvolt-like debacle.

That said, the case for climate infrastructure startups is simple: their success is instrumental to everything around them. Battery production for mobility, nuclear fusion plants and electrolyser factories for energy independence, carbon capture for cutting emissions: whatever the cost may be, innovation gaps will have to be filled eventually.

Sifted take

It’s not all about quick money for investors, with specialised funds open to offering looser terms to projects with delayed returns. The funding risk doesn’t lie on the clear need for advanced climate infrastructure, nor on the institutional interest to accelerate it, but rather in choosing which mega projects are worth betting big on. How many will Europe need? It won’t be a crowded list: a few choice big-ticket ones could be just the trick.
