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

NET-Fuels开发了一种新的途径，通过热化学转化、合成气中氢的分离、尾气的氧燃料燃烧、二氧化碳转化为甲烷的生物电化学转化和生物炭中的碳封存，从低价值的生物残留物（如消化物、灾木、修剪）中生产负碳生物燃料。该过程还将产生额外的生物燃料中间体（高质量热解油），该产品已被证明可以转化为插入式燃料。该项目将把综合过程带到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、经济性能、环境和社会可持续性方面）。为此，它汇集了国际公认的专家联盟，包括生物质热化学转化、生物反应器设计、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展、公众参与和社会可持续性分析。如果利用欧洲附录九A部分中列出的总可用原料池的三分之一到四分之一，到2030年，Net-Fuels系统将能够提供2500万吨油当量的先进生物燃料（占运输燃料消耗的7%）。与这一目标相对应，净燃料将确保1.1亿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.
