For the UK to achieve net carbon neutrality by 2050, it is estimated that the mix of Greenhouse Gas Removal (GGR) technologies required will equate to ca. 35 M tonnes of carbon (MtC) p.a. Biochar can potentially make a major contribution both to this target and the adoption of farming practices described by the Committee on Climate Change (2020) to achieve a 64% reduction by 2050 in greenhouse gas emissions across agriculture, land use and peatlands by 64% from the 2017 level of 16 MtC. However, there are some significant challenges to overcome. There is limited availability of virgin wood to produce biochar and there are no large-scale production plants operating in the UK. Further, as well as economic viability and societal acceptability, there are concerns over biochar stability with initial degradation occurring over relatively short timescales. We propose to conduct the most ambitious and comprehensive demonstration programme to date involving arable and grassland, woodland, contaminated land, and where soil erosion control is required. Using over 200 tonnes of biochar, we will address uncertainties regarding the extent and scope of deployment and its stability with respect to carbon sequestration, together with quantifying effects on ecosystem services. The proposed research programme is highly inter-disciplinary, bridging engineering, geoscience, bioscience, social science and techno-economics, specifically designed to provide answers to the key challenges outlined and establish whether biochar can make a significant contribution to meet the UK's 2050 GGR target . The quantitative approach that we will adopt based on internationally leading science represents a step-change for biochar research in the UK, which has focussed primarily on agricultural benefits and not addressed the key challenges regarding carbon sequestration that are needed to reduce the uncertainty for policy development. Alternative bio-derived feedstocks that will significantly increase the production potential by >1 MtC p.a, will be identified. Two of our industrial partners, CEG and CPL operate demonstration and commercial plants, making them ideally placed to establish biochar production at scale in the UK. The extensive trials will provide a sound basis for establishing the potential for biochar deployment across agriculture, contaminated and reclaimed land and woodland, enabling regional and national scale effects to be quantified. To date, most field trials have been relatively localised and short-term. We aim to deploy char in large-scale farming and land management scenarios where the effects of 'real-world' management practices on the behaviour of char will be evaluated. Our excellent links with the farming sector, including the Agriculture and Horticulture Development Board and the National Farmers' Union, will provide the springboard to explore a wide range of stakeholder perspectives on biochar's role in GGR to aid policy development. . The Demonstrator will address concerns over environmental health and soil ecosystem service functioning and will provide the first comprehensive assessment of biochar stability in the UK and its impact on greenhouse gas soil emissions, with our international leading biological science and analytical capabilities. This will enable robust policy to be developed in which payments are based on the amount of carbon sequestered over extended timescales. Our business models will be based on our integrated life cycle and techno-economic analysis, identifying the carbon prices required to make deployment feasible and incorporating co-benefits of biochar use in agriculture. The Demonstrator will provide the Hub with all the necessary scientific, technological, environmental, economic and societal evidence to enable biochar deployment to be assessed in relation to other GGR approaches.

为了使英国在2050年之前实现净碳中和，据估计，所需的温室气体去除（GGR）技术组合将相当于约100万吨。每年3500万吨碳（MtC）生物炭可以为实现这一目标和采用气候变化委员会（2020年）描述的农业实践做出重大贡献，到2050年，农业，土地利用和泥炭地的温室气体排放量将从2017年的16 MtC水平减少64%。然而，仍有一些重大挑战需要克服。生产生物炭的原始木材有限，英国没有大规模的生产工厂。此外，除了经济可行性和社会可接受性之外，还存在对生物炭稳定性的担忧，其初始降解发生在相对较短的时间尺度内。我们建议进行迄今为止最雄心勃勃和最全面的示范方案，涉及可耕地和草地、林地、受污染的土地以及需要控制土壤侵蚀的地方。使用超过200吨生物炭，我们将解决部署的程度和范围及其在固碳方面的稳定性的不确定性，以及对生态系统服务的量化影响。拟议的研究计划是高度跨学科的，桥接工程，地球科学，生物科学，社会科学和技术经济学，专门设计用于提供所概述的关键挑战的答案，并确定生物炭是否可以为实现英国的2050年GGR目标做出重大贡献。我们将采用的基于国际领先科学的定量方法代表了英国生物炭研究的一个步骤，该研究主要集中在农业效益上，而没有解决减少政策制定不确定性所需的碳封存方面的关键挑战。将确定替代的生物衍生原料，这些原料将使生产潜力显著增加>1 MtC/a。我们的两个工业合作伙伴，CEG和CPL经营示范和商业工厂，使他们成为在英国大规模建立生物炭生产的理想选择。广泛的试验将为确定在农业、受污染和开垦的土地和林地中部署生物炭的潜力提供良好的基础，使区域和国家规模的影响得以量化。迄今为止，大多数田间试验都是相对局部和短期的。我们的目标是在大规模的农业和土地管理方案中部署炭，在这些方案中，将评估“现实世界”的管理实践对炭行为的影响。我们与农业部门的良好联系，包括农业和园艺发展委员会和全国农民联盟，将为探索生物炭在GGR中的作用的广泛利益相关者观点提供跳板，以帮助政策制定。.该演示器将解决人们对环境健康和土壤生态系统服务功能的担忧，并将利用我们国际领先的生物科学和分析能力，首次全面评估英国生物炭的稳定性及其对温室气体土壤排放的影响。这将有助于制定强有力的政策，根据长期固碳量进行支付。我们的商业模式将基于我们的综合生命周期和技术经济分析，确定使部署可行所需的碳价格，并将生物炭在农业中使用的共同效益纳入其中。示范项目将为中心提供所有必要的科学、技术、环境、经济和社会证据，以便能够评估生物炭部署与其他GGR方法的关系。
