ion Ventures was founded in London in 2018 and operates across the UK and Southeast Asia. The firm develops and owns renewable generation, offers expert advisory services and partners on projects that enhance clean electrification and deliver flexible power infrastructure. By integrating storage, demand response and hybrid generation, the company addresses shifting supply and demand patterns, intermittent renewables and electric vehicle charging needs. Its team brings extensive project development experience in both Europe and Asia, focusing on practical solutions that strengthen energy security and support the transition to low-carbon power systems.
Rather than investing equity in external technology firms, ion Ventures secures financing for its own energy assets and collaborates with institutional backers to advance large-scale projects. In 2024, net-zero asset manager HYCAP acquired a £10 million stake in the company, reinforcing its clean power ambitions. The firm also formed a joint venture, Flexion Energy, which obtained a £150 million infrastructure investment to expand UK energy storage capacity. Capital raises are structured to support battery storage, solar and wind projects, with an emphasis on long-term performance and reliable returns.
ion Ventures has pioneered grid-scale battery storage in Europe, deploying the continent’s first Tesla system and bringing more than 200 MW of storage capacity online to date. Its project portfolio includes over 50 MW of operational assets in Southeast Asia and a pipeline of 115 MW of ready-to-build sites in the UK. The company designs hybrid installations that pair solar PV and wind with batteries, optimizing network stability and revenue streams. Advisory services cover technical feasibility, commercial modeling and integration of virtual power plant platforms, helping clients unlock flexibility value.
