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.

Trends to watch
To VC or not to VC
While climate cashflows have been bubbly for some time, only a handful of powerful VCs have touched high-capex, high-risk ventures so far.
Infrastructure startups will need to keep exploring creative capital streams outside of standard return-based VC, including public funding, convertible notes, partnerships and debt.
It’s not only energy – foodies, hear us out
If you don’t know how to build a nuclear fusion plant, don’t worry. With climate-friendly rules developing quickly, new physical assets are also expected to be in demand outside of traditional energy verticals.
Assuming they get the thumbs up from European regulatory bodies, subsectors like alternative proteins will also require big, physical assets — in this case bioreactors to develop lab-grown meat.
Keeping it in Europe (plants and people alike)
It’s not only the actual infrastructure: specialised talent to build it is pricey too, and enticing later-stage ventures overseas are a threat to keeping workers in Europe.
Stiff competition from China and the US in particular, with its massive green subsidy plan, risks causing more projects to pivot away from Europe – although it’s prompting proportional subsidiary responses from Brussels and national governments.
Innovation or integration
New climate tech isn’t that new anymore – startups have figured out the basics and are moving onto integration with existing infrastructure systems.
Infrastructure startups are looking into renting partners’ plants to integrate their tech, including using data centres for thermal energy, which also slashes capital expenditure.

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.
Rising stars
Launched by a team of physicists, it develops parts for nuclear fusion reactors: specifically, liquid metal to insulate reaction chamber walls and high-temperature superconducting coils. Key sustainability players such as Lowercarbon Capital and Norrsken VC are on itsF cap table.
