With today's situation British electric vehicle battery producers will be fully dependent on supply of anode material from China. Greenroc intends to change this by developing domestic production of graphite anode material for the British battery and electric car industry without involvement of Chinese companies or investments during production. The feed for such production is responsibly mined graphite from Greenroc's own world-class deposit in South Greenland. The Feasibility Study will provide fundamentals of the processing of natural graphite flakes to graphite anode material including a new innovative anode processing unit manufactured by German companies and compare such unit with current state-of-the-art standard processing unit of Chinese manufacturing.A key aspect in the energy transition is the shift from diesel and gasoline-driven vehicles to electric vehicles (EVs). Commercial EVs are powered by EV-batteries, predominantly technology of Li-ion and Li-Iron-Phosphate batteries. These batteries contain at least 20% by weight of graphite as anode material. Presently all the graphite anode materialused by EV battery manufacturers is processed and produced in China, disregarding the origin of the graphite concentrate precursor. Aside from the inherited supply risk associated with European battery manufacturers being overly dependent on Chinese production, there is a large CO2 footprint associated with the shipping of graphite concentrate from overseas to China and the subsequent shipping of the graphite anode material from China to battery factories in Europe, involving up to 70 days at sea. Greenroc's Amitsoq graphite deposit is located in South Greenland only four to five days of shipping time from UK ports.Given the size and quality of the Amitsoq graphite deposit, Greenroc has the ambition to produce the highest quality graphite anode material in quantities that may exceed UK EV battery factory needs and therefore in turn could provide significant export opportunities.

在目前的情况下，英国电动汽车电池生产商将完全依赖中国供应的负极材料。格林洛克打算改变这种状况，在没有中国公司参与或投资的情况下，为英国电池和电动汽车行业开发国内生产的石墨负极材料。这种生产的原料是从格林洛克自己在南格陵兰岛的世界级矿床中负责任地开采的石墨。可行性研究将提供将天然石墨薄片加工成石墨阳极材料的基本原理，包括德国公司制造的一种新的创新阳极处理装置，并将这种装置与目前中国制造的最先进的标准处理装置进行比较。能源转型的一个关键方面是从柴油和汽油驱动的汽车转向电动汽车（ev）。商用电动汽车由电动电池供电，主要是锂离子电池和磷酸铁锂电池技术。这些电池含有至少20%重量的石墨作为阳极材料。目前，电动汽车电池制造商使用的石墨负极材料都是在中国加工和生产的，而不考虑石墨精矿前驱体的来源。除了与欧洲电池制造商过度依赖中国生产相关的固有供应风险外，从海外向中国运输石墨精矿以及随后从中国向欧洲电池工厂运输石墨负极材料（涉及长达70天的海上运输）会产生大量的二氧化碳足迹。Greenroc的Amitsoq石墨矿床位于南格陵兰岛，从英国港口出发只需4到5天的航运时间。考虑到Amitsoq石墨矿床的规模和质量，Greenroc有雄心生产最高质量的石墨阳极材料，其数量可能超过英国电动汽车电池厂的需求，从而可以提供重要的出口机会。
