Battery breakthrough – RISE tests a new kind of sustainable silicon from GREEN14

The battery team at RISE has received the first batch of silicon-based anode material produced by GREEN14. This new material was created at GREEN14’s pilot facility using a breakthrough technology that extracts silicon directly from quartz using hydrogen plasma – entirely fossil-free.

What makes this method unique is how much cleaner and simpler it is compared to today’s conventional silicon production. Instead of using coal and extreme temperatures in arc furnaces – or hazardous chemicals – GREEN14 relies solely on electricity and hydrogen. The result is a high-purity, high-performance silicon with a dramatically lower climate footprint. A major step toward a more sustainable battery value chain.

“Having our silicon tested by RISE is an important milestone for us. It proves that our technology works – not just in theory, but in practice. We want to show that it’s possible to produce advanced battery materials without burdening the planet, and this is a concrete first step,” says Adam Podgorski, Founder and CEO of GREEN14.

Silicon in anode materials is a key enabler for the next generation of batteries, which demand higher energy density and longer lifespan. The next step is for RISE to produce a so-called coin cell using GREEN14’s material to evaluate its real-world performance. (A coin cell is a small, round test battery – about the size of a watch battery – commonly used in labs to assess new battery materials in early-stage testing.)
