NET-Fuels Increasing biomass conversion efficiency to carbon-negative sustainable biofuels by combination of thermal and bio-electrochemical processes

Net-Fuels开发了一种利用低价值的生物残留物(如沼气、灾害木、修剪)生产碳负生物燃料的新途径，通过热化学转化、从合成气中分离氢气、尾气的富氧燃料燃烧、二氧化碳生物电化学转化为甲烷和生物炭中的碳固定相结合的方法。这一过程还将产生一种生物燃料中间体(高质量热解油)作为额外的产品，该中间体具有已证实的转化为一次性燃料的路线。该项目将把综合进程带到TRL 5，为进一步的示范和验证项目提供一个平台(在技术可行性、经济绩效以及环境和社会可持续性方面)。在这样做的过程中，它汇集了国际公认的生物质热化学转化、生物反应堆设计、环境可持续性和生命周期分析、动态建模、生物炭利用、经济分析和商业案例开发以及专门的外联、公众参与和社会可持续性分析方面的专家联盟。净燃料系统将能够在2030年提供2500万吨先进生物燃料(占运输燃料消费的7%)，如果利用附件九A部分所列欧洲现有原料总库的三分之一至四分之一。与这一目标相对应，净燃料将确保110公吨二氧化碳的净负排放。

NET-Fuels develops a novel pathway to produce carbon-negative biofuels from low value biogenic residues (such as digestate, calamity wood, pruning) through a combination of thermochemical conversion, separation of hydrogen from the syngas, oxy-fuel combustion of the tail gas, bio-electrochemical conversion of CO2 into methane and carbon sequestration in the biochar. The process will also generate as an additional product a biofuel intermediary (high quality pyrolysis oil) which has proven conversion route into drop-in fuels. The project will take the integrated process to TRL 5, providing a platform (in terms of technical feasibility, economic performance, and environmental and social sustainability) for further demonstration and validation projects. In doing so it brings together a consortium of internationally recognized experts in biomass thermochemical conversion, bioreactors design, environmental sustainability and life cycle analysis, dynamic modelling, biochar utilisation, economic analysis and business case development and dedicated outreach, public engagement, and social sustainability analysis. The Net-Fuels system will be able to deliver 25 Mtoe of advanced biofuels in 2030 (7% share of the transport fuel consumption), if exploiting between one third and one fourth of the total pool of available feedstock listed in Part A of Annex IX in Europe. In correspondence of such objective, NET-Fuels will ensure 110 Mt of CO2 of net negative emission.
