CarbonScape Limited has been awarded a foundational “Composition of Matter” patent (EP-4 079 686 B1) by the European Patent Office, marking a significant advancement in sustainable battery materials. This patent, currently undergoing validation in 40 European countries, enhances CarbonScape’s capacity to provide affordable, domestically produced, and sustainable battery-grade graphite, which is crucial for Europe’s expanding battery manufacturing sector.
The patented technology enables the conversion of forestry by-products, such as woodchips and sawdust, into high-performance graphite suitable for use in batteries. This innovation offers European manufacturers a local alternative to imported anode materials, thereby reducing dependence on natural graphite mining and the energy-intensive production methods predominantly controlled by China, which supplies 95% of the world’s battery-grade graphite. By enabling production within European Union borders, CarbonScape provides a cost-effective and environmentally friendly option that supports the region’s battery mineral sovereignty goals.
“Europe’s electrification ambitions depend on securing a cost-competitive, local and ESG-aligned graphite supply chain,” said Vincent Ledoux-Pedailles, Chief Commercial Officer of CarbonScape. “This patent enables us to deploy our technology across the European Union, leveraging low-cost, renewable domestic forestry feedstocks and accelerating the continent’s journey toward battery mineral sovereignty.”
CarbonScape’s technology aligns with several European policies, including the EU Battery Regulation, the Green Deal Industrial Plan, and the proposed Critical Raw Materials Act, all of which prioritize local and low-carbon graphite production. Additionally, producing graphite within Europe reduces shipping distances, lowers Scope-3 emissions, and mitigates geopolitical risks for cell manufacturers and electric vehicle producers.
The European patent complements CarbonScape’s recent U.S. patent (US 12 187 615 B2), granted in March 2025, highlighting the company’s leadership in sustainable graphite technology and supporting plans for commercial plants in both Europe and North America. Recent achievements include a 90% spheroidization yield in converting raw graphite to battery-grade biographite and the completion of engineering for a demonstration plant set to begin operations in 2026. The company has also secured long-term feedstock agreements in Europe and the United States, positioning itself at the forefront of sustainable battery material innovation.
CarbonScape Limited, headquartered in New Zealand, is expanding its operations into Europe and North America. The company has operated a pilot plant in New Zealand since 2018 and is preparing to launch its demonstration plant, the final step before full commercialization. With investments from major battery manufacturer ATL and forestry corporation Stora Enso, CarbonScape aims to establish multiple industrial plants across Europe and North America, contributing to the global transition to clean energy and electric mobility.
