The utilisation of late-harvest grass for biochar and heat generation on farm-level is being studied as a potential negative emissions technology. Technical (energy provision and carbon sink), economic (cost vs. benefit), political (regulatory framework) and social (SWOT) perspectives are being evaluated. Technical feasibility has been demonstrated with three different farm-scale technologies and the energetic and carbon-sink potential evaluated. When a continuously operating allothermal unit is evaluated, 35 % of the input biomass energy content can be utilized for heating a farm, in combination with the potential to provide a carbon sink. The cost-benefit analysis shows important monetary savings when including the agronomic value (based on the market price) of the produced biochar. An assessment of the regulatory framework of biochar production in Germany presents a multitude of regulations applying to such technologies some of which provide a hurdle to navigate and may incur excessive costs for farmers as small-scale biochar producers. A SWOT analysis of a case in Brandenburg, Germany highlights strengths and opportunities, but also obstacles such as lack of infrastructure and regulatory support. This study highlights the need for further development of suitable technology and research on the long-term economic and carbon sink potential of biochar PB Elsevier Ltd on behalf of Institution of Chemical Engineers SN 2352-5509 YR 2023 FD 2023-03-08 LK https://hdl.handle.net/10347/44202 UL https://hdl.handle.net/10347/44202 LA eng NO Thomas Heinrich, Hyunjin Park, Richard Orozco, Zhengqiu Ding, Vanessa Álvarez-López, María Rosa Mosquera-Losada, Leopold Steinbeis, Thomas Hoffmann, Biochar production from late-harvest grass – Challenges and potential for farm-scale implementation, Sustainable Production and Consumption, Volume 37, 2023, Pages 256-267, ISSN 2352-5509, https://doi.org/10.1016/j.spc.2023.02.019.
