Ethylene is the chemical industry’s primary building block. SolDAC’s ambition is to reinvent the ethylene industry by proving (TRL4) an emerging breakthrough technology for producing technically and economically competitive, socially desirable and climate-neutral (sustainable) ethylene and co-product ethanol (C2 products) from solar energy and air. The project features a photo-electrochemical conversion (PEC) unit, being electrochemistry the only possible route for direct conversion of carbon dioxide into ethylene. The PEC exploits bandwidth-selected light from a solar collector (FSS) thatsplitsthe solarspectrum for electricity and heat generation at efficiency higher than standalone PV modules and standalone solar thermal collectors. Heat is used in an innovative direct air capture (DAC) unit at ultralow temperature (~60°C), fostering the eventual circular integration with heat networks. The DAC unit removes carbon dioxide from the air, concentrates it to 95+% and compresses it to feed the PEC stack and a pipeline for carbon dioxide storage. This allows the carbon footprint of the whole sun-to-chemicals process to be offset and enables gain in carbon credits, opening an opportunity to exceed climate-neutrality and produce carbon-negative C2 products. The process is energetically self-sufficient, economically viable and carbon-negative on the condition that each unit (DAC, PEC, FSS) reach new targets in efficiency. That is exactly the high-risk/high return outcome expected in the project. The research is balanced to overcome technical, early-stage social and market barriers by exploiting the expertise of its 8 partners (SMEs in the renewable technology field, leading EU research institutions and one networking NGO). This project performs all the necessary groundwork for the full deployment of the process before 2050 through activities that build up a new ecosystem of stakeholders, making Europe the first circular, climate-neutral and sustainable economy

乙烯是化学工业的主要组成部分。SolDAC的雄心是通过证明(TRL4)一项新兴的突破性技术来重塑乙烯行业，该技术可利用太阳能和空气生产具有技术和经济竞争力、社会可取和气候中性(可持续)的乙烯和联产乙醇(C2产品)。该项目以光电转化(PEC)单元为特色，这是二氧化碳直接转化为乙烯的唯一可能的电化学途径。PEC利用来自太阳能集热器(FSS)的带宽选择的光，该集热器分割太阳能光谱用于发电和制热，效率高于独立的光伏组件和独立的太阳能集热器。创新的直接空气捕集(DAC)装置在超低温(~60°C)下使用热量，促进了最终与热网络的循环集成。DAC单元从空气中去除二氧化碳，将其浓缩到95%以上，并将其压缩，以提供给PEC电堆和用于二氧化碳存储的管道。这使得整个从太阳能到化学品的过程的碳足迹得以抵消，并能够获得碳信用，从而打开了超过气候中和和生产碳负C2产品的机会。在每个单元(DAC、PEC、FSS)达到新的效率目标的条件下，这一过程在能源上是自给自足的，在经济上是可行的，而且是碳负的。这正是项目中预期的高风险/高回报结果。这项研究通过利用其8个合作伙伴(可再生技术领域的中小企业、领先的欧盟研究机构和一个联网的非政府组织)的专业知识，平衡地克服了技术、早期社会和市场障碍。该项目通过建立一个新的利益攸关方生态系统的活动，为在2050年前全面部署这一进程进行所有必要的基础工作，使欧洲成为第一个循环、气候中立和可持续的经济
