December 16, 2025: University of Cambridge spin-out Kodiaq Technologies said on December 10 it had completed a £850,000 ($1.1 million) funding round to scale UK-developed organic electrolytes for metal-free flow battery storage.

Kodiaq, which said it is backed by more than 20 high-net-worth investors across the climate tech and deep tech sectors, claims its technology has the potential to provide a scalable, cost-effective alternative to lithium and vanadium-based systems.

Using organic chemistry rather that mined metals also offers environmental and supply-chain benefits for the energy storage industry, Kodiaq said.

The firm claims its electrolytes enhance energy density in storage and long-duration performance in flow batteries, improving system economics by delivering more energy from the same hardware and significantly reducing the investment per unit of storage capacity.

Kodiaq’s electrolytes do not require expensive and complex enclosures to isolate them from air and the firm said it has developed “a library of electrolytes” for customers to choose what fits their needs best.

The pilot projects pave the way to kicking off an additional “substantial funding round” in 2026 to establish scaled-up demonstration projects worldwide.

“Energy storage doesn’t have to be dependent on the price or availability of metals. Our approach will replace that dependency with something globally available, sustainable, and scalable,” CEO David Fyfe said.
