Rivan, a company enabling energy security through synthetic fuels, has raised £10 million in funding led by Plural, with participation from 20VC, NFDG (Nat Friedman and Daniel Gross), and prominent angel investors Patrick and John Collison (Stripe). The capital will be used for R&D on Rivan's electrolyser, direct-air-capture (DAC) and Sabatier reactor modules, as well as scaling its pilot plant up to 1MW.

Green Angel Ventures has backed Sention Technologies in its latest seed round, bringing the company's total funding to £3.7 million as it commercialises its battery diagnostics technologies.

Green Angel Ventures has made a follow-on investment in PES Technologies, which has just closed a £1.3m pre-Series A funding round. The round was led by TSP Ventures, with participation from Green Angel Ventures, Kero Development Partners, and Moorhampton Investments Limited.

Carbon Cell, a materials innovation company, has raised £1.2m in a pre-seed round to scale its novel, plastic-free foam made from biochar and natural polymers. This round was led by Green Angel Ventures and Counteract, with participation from HERmesa, RCA Design and Innovation S/EIS Fund, and One Planet Capital.

At the core of Carbon Cell's solution is biochar, a carbon-rich material made from agricultural waste that would otherwise be burned or left to decompose. Combined with natural polymers, this creates a high-performance, fully compostable foam that not only avoids plastics and petrochemicals but also boasts a negative carbon footprint because of the carbon captured within the biochar used to make the material.

The new funding will enable Arda to make advancements in the R&D of its first product, New Grain^TM, a plant-based, plastic-free, leather-like material derived from spent grain, the byproduct of beer and whisky production.

Fuel Ventures has led an investment round for pioneering climate-success company, 51toCarbonZero, the first platform to ensure effective corporate transition to net zero while boosting clients' business performance.
