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 maximises returns on investment, minimises 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 optimise 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 upscaling 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 fulfil the strategic objectives of the EU Green Deal and the Agenda for Sustainable Development.

Geological fluids通常含有大量的元素，欧盟认为这些元素是“关键”原材料（CRM）。初步计算表明，即使是一口井也有可能生产欧盟需求的个位数百分比。热能和矿物质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，不会留下采矿遗产，碳足迹接近零，并能够在国内供应CRM。为了评估总体供应潜力，CRM-地热将通过收集新数据和在欧洲和东非对其CRM含量进行威尔斯采样来扩大现有的地热流体图谱。将评估不同地质条件下联合开采的潜力。提取/分离技术是存在的，但需要适应这些系统的苛刻条件（高温、高压和盐度）。材料和流程的组合将在实验室规模进行评估，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的工厂，并在现有的地热地点进行试点研究，调查升级和系统集成。在技术发展的同时，还将评估环境和社会影响，以确保善治。将开发一个符合UNFC/CIMMS的报告模板，以建立投资者、监管机构和公众之间的信任。该项目将推进利益攸关方参与的关键参考点，以获得和维护“社会运营许可证”。联合开采为中小企业和大公司创造了新的商业机会，将研究其在未来可能的市场发展情况下的经济性，以期提出适当的商业模式。CRM-地热将开辟一个潜在的巨大的未开发资源和部署解决方案，以帮助欧洲实现欧盟绿色交易和可持续发展议程的战略目标。
