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.

地热流体通常含有大量欧盟认为是“关键”原材料（CRM）的元素。初步计算表明，即使是单口井也有可能生产欧盟需求的个位数百分比。热和矿物的联合开采可以最大限度地提高投资回报，最大限度地减少对环境的影响，不需要额外的土地使用，不留下采矿遗产，碳足迹接近于零，并且可以实现CRM的国内供应。为了评估整体的供应潜力，CRM-地热将通过收集新的数据和取样欧洲和东非的井来扩大现有的地热流体图谱。将评价不同地质环境联合开采的潜力。萃取/分离技术已经存在，但需要适应这些系统的恶劣条件（高温、高压和盐度）。材料和流动方案的组合将在实验室规模上进行评估，以优化不同地热设置和CRM的系统。一个模块化的移动工厂将被开发并部署在现有的地热站点上，以进行试点研究，调查扩大规模和系统集成。在技术发展的同时，将对环境和社会影响进行评估，以确保善政。将开发一个符合UNFC/UNRMS标准的报告模板，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，以获得并保持“社会经营许可证”。联合开采为中小企业和大公司创造了新的商业机会，我们将研究其在未来可能的市场发展下的经济效益，以提出合适的商业模式。crm地热将打开一个潜在的巨大的未开发资源，并部署解决方案，以帮助欧洲实现欧盟绿色协议和可持续发展议程的战略目标。
