Power-to-gas via microbial electrosynthesis of methane from biogenic CO2

英国政府承诺在2035年之前实现电力系统的脱碳。为了确保这一雄心壮志成为现实，我们需要加倍努力，为长期能源储存部署可靠且有弹性的基础设施。EFuels Technologies Ltd正在开发一种新的发电转化为甲烷的技术，将可再生电力储存在现有的天然气基础设施中。现有的技术是集成的多步骤过程。它们价格昂贵，转换效率低，能量损失大。我们的解决方案利用微生物电合成的科学原理在一步内生产合成甲烷，因此成本只有现有解决方案的一小部分。快速启动创新资金将使公司能够为该技术建立市场验证的证据和实验室规模的原型。该项目将在萨里大学的能源实验室进行，资金将用于人员配备、材料和消耗品。如果这项技术成功升级，发电机和聚集商可以利用减少的电力将生物来源的二氧化碳转化为甲烷，并从在平衡能源市场内销售服务中获利。生物来源的二氧化碳可以从沼气中获得(50-40%的二氧化碳)。这项技术可以在电力和天然气行业之间建立一种独特的双向联系，这可以帮助市场参与者以更高的灵活性实现资产价值最大化。

The UK Government has committed to decarbonising the electricity system by 2035\. To ensure this ambition becomes a reality, we need to double down on efforts to deploy a reliable and resilient infrastructure for long-term energy storage. Efuels Technologies Ltd is developing a novel power-to-methane technology to store renewable electricity within the existing natural gas infrastructure. Incumbent technologies are integrated multi-step processes. They are expensive and have poor conversion efficiencies and energy losses. Our solution leverages the scientific principles of microbial electrosynthesis to produce synthetic methane in one single step, and therefore at a fraction of the costs of Incumbent solutions.The Fast Start innovation funding will allow the company to build evidence of market validation and a bench-scale prototype for the technology. The project will take place in the Energy Laboratory of the University of Surrey and the funding will be spent on staffing, materials, and consumables. If the technology is successfully upscaled, generators and aggregators could use curtailed electricity to convert biogenic CO2 into methane and profit from selling services within the Balancing Energy Market. The biogenic CO2 can be obtained from biogas (50-40% CO2). The technology could create a unique bi-directional link between the electricity and gas industry, which could help market participants maximise the value of their assets with a higher degree of flexibility.
