Climate Tech at Signal · Copenhagen, Denmark

I spent four years at Northvolt in Stockholm, working on operations and supplier strategy during the period when European battery optimism was at its loudest. It was an extraordinary education in the difference between a climate narrative and a factory ramp.

Software people tend to talk about climate tech as if the hard part is adoption. In industrial climate tech, the hard part is often everything before adoption: permitting, grid interconnection, equipment lead times, qualification cycles, working capital, and whether a supplier in another country can deliver a component to spec for the 10,000th time, not just the first.

After Northvolt, I joined a Copenhagen-based climate fund focused on infrastructure-adjacent startups: grid software, heat pumps, industrial efficiency, carbon accounting that actually connected to operations, and battery services. Investing gave me a wider view, but operating made me skeptical in useful ways. A beautiful model is not a business until it survives procurement, installation, maintenance, and an angry operations manager at 2 a.m.

I write about the practical constraints shaping climate tech: where software can accelerate deployment, where it becomes a reporting layer over unchanged physical systems, why grid bottlenecks matter more than pitch decks admit, and how Europe can build industrial capacity without pretending policy is the same thing as execution.

I live in Copenhagen and still visit factories whenever I can. You can learn more from one shift supervisor than from a week of conference panels.
