Geothermal fluids often carry high amounts of elements that the EU considers as 'critical' raw materials (CRM). Preliminary calculations show that even a single well has the potential to produce single-digit percentages of the EU needs. Combined extraction of heat and minerals maximizes returns on investment, minimizes environmental impact, requires no additional land use, leaves no mining legacies, has near-zero carbon footprint, and enables domestic supplies of CRM. To assess overall supply potential, CRM-geothermal will enlarge an existing geothermal fluid atlas by collecting new data and sampling wells for their CRM content in Europe and East Africa. The potential of different geological settings for combined extraction will be evaluated. Extraction/separation techniques exist but need to be adapted to the harsh conditions of such systems (high temperature, pressure, and salinities). Combinations of materials and flow-schemes will be assessed at lab-scale to optimize systems for different geothermal settings and CRM. A modular, mobile plant will be developed and deployed at existing geothermal sites to conduct pilot studies, investigating up scaling and system integration. The technological developments will be accompanied by assessments of environmental and social impacts to ensure good governance. An UNFC/UNRMS compliant reporting template will be developed to create trust among investors, regulators, and the public. The project will advance key reference points for stakeholder engagement, in order to obtain and maintain a 'social license to operate'. Combined extraction creates new business opportunities for both SMEs and larger companies, and its economics under likely future market developments will be investigated with a view to proposing suitable business models. CRM-geothermal will open up a potentially huge untapped resource and deploy solutions to help Europe fulfill the strategic objectives of the EU Green Deal and the Agenda for Sustainable Development.

地热流体通常具有大量元素，欧盟将其视为“关键”原材料（CRM）。初步计算表明，即使是一个井也有可能产生欧盟需求的单位数字。热量和矿物质的共同提取可最大程度地提高投资回报，最大程度地减少环境影响，不需要额外的土地利用，不带矿业遗产，具有接近零的碳足迹，并为CRM提供了家庭供应。为了评估整体供应潜力，CRM-Geothermal将通过收集新数据并为其在欧洲和东非的CRM含量采样新数据和采样井来扩大现有的地热液体图集。将评估不同地质环境合并提取的潜力。存在提取/分离技术，但需要适应此类系统（高温，压力和盐度）的恶劣条件。将在实验室尺度上评估材料和流程检查的组合，以优化不同地热设置和CRM的系统。将开发一个模块化的移动工厂，并在现有的地热站点进行开发，以进行试点研究，并研究缩放和系统整合。技术发展将伴随着对环境和社会影响的评估，以确保良好的治理。将开发一个符合UNFC/UNTRS的报告模板，以在投资者，监管机构和公众之间建立信任。该项目将推进利益相关者参与的关键参考点，以获取和维护“经营社会许可”。合并的提取为中小企业和较大的公司创造了新的商机，其在可能的未来市场发展下的经济学将进行研究，以提出合适的商业模式。 CRM-Geothermal将开放潜在的巨大尚未开发的资源和部署解决方案，以帮助欧洲实现欧盟绿色协议的战略目标和可持续发展的议程。
