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、从合成气中分离氢、尾气的氧燃料燃烧、将CO2生物电化学转化为甲烷和生物炭中的碳封存等组合，从低价值生物源残留物（例如消化物、灾难木材、修剪）生产负碳生物燃料。该工艺还将产生一种额外的产品，即生物燃料中间体（高质量的热解油），它已被证明可以转化为直接使用的燃料。该项目将把综合工艺带到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推广，公众参与和社会可持续性分析专家的联盟。净燃料系统将能够在2030年提供2500万吨油当量的先进生物燃料（占运输燃料消耗的7%），如果利用附件九A部分所列欧洲可用原料总量的三分之一到四分之一。为了实现这一目标，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.
