The financing round was backed by strategic e-mobility funds to accelerate the development of sodium battery technology.

"On behalf of our entire team, I am delighted to announce the completion of this pre-seed fund raise and would like to thank our expert strategic investors for their vision and full support. Our quasi-solid-state sodium battery offers significant cost, sustainability, and safety benefits for the BEV industry. TaiSan’s novel electrolyte and anode innovations will bring this chemistry to the next level – batteries becoming smaller, lighter, with best-in-class energy density, and major cost savings too. Our new investment will allow us to ramp-up development and we will be announcing some game-changing results in the very near future. Watch this space."

GV led the Series A round for the climate risk platform, which will use the capital to scale its presence in North America and Europe.

"In just over one year since going to market, Climate X has become one of the world’s fastest growing providers of physical climate risk data and analytics, driving value for global financial services clients with over $6.5 trillion in combined AUM. Assessing the impact of physical climate risk on asset valuations and business operations is now a necessity, not a nice-to-have."

Debt

The London-based residential energy services company has raised debt financing from Barclays to widen access to domestic green technology.

"Many homeowners naturally want to invest in renewable technologies but are put off by the extraordinarily high upfront costs. That’s why we’re focused on removing barriers to help more households take control of their energy bills and carbon emissions. We’re delighted to be working with Barclays to help us develop and scale flexible finance solutions with all-inclusive cover built-in, to enable homeowners to make the switch to clean, green energy with confidence."

"Our ambition is to deliver the best fast-charging batteries to unlock the electrification of heavy-duty vehicles. The investment from our partners Volta Energy Technologies, CBMM, BGF and Cambridge Enterprise Ventures cements our ambition to achieve full-scale commercialisation and full production volume."
— Jean de La Verpilliere, Chief Executive Officer
