Best Energy Tech Companies in Spain
The 375 best Energy Tech companies in Spain in 2026, ranked by funding and momentum. Funding, investors, founders, valuation, tech stack and live signals. Top: Soty Solar.
Spain's Energy Tech sector has real money behind it. We're tracking 375 companies with $894M in total disclosed funding, and the spread tells you something: Submer leads the pack at $90M, Soty Solar sits close behind at $120M, and Stark Future has pulled in $80M, all without a unicorn in sight yet. The sector's growing at a CAGR of roughly 7.1%, driven by rising global energy demand and the push to digitize and optimize production processes. And as shown in 2022 research, next-generation battery chemistry is accelerating the commercial case for exactly the kind of EV and solar plays dominating Spain's funding rounds right now.
So what's the momentum signal? Across 138 energy-related apps, median install growth is running at plus 28% year-over-year, which tells you consumer and B2B interest isn't theoretical. Hot themes this quarter are EV powertrain advancements, solar electricity generation, and EV battery technology, and Spain's investor mix, including EIT InnoEnergy, the EIC Fund, and Lanzadera, is positioned right across all three. I'd keep a close eye on emerging green energy plays heading into 2025 as the regulatory environment tightens and capital chases fewer, larger bets.
