ABSTRACT

This article provides perspectives on the opportunities and challenges of integrating biomass liquefaction plants (pyrolysis, hydro-pyrolysis, hydrothermal liquefaction, liquefaction in hydrocarbon solvents, etc.) with intermittent renewables such as wind and solar photovoltaic (PV) to provide energy storage and support the development of biofuel production. A techno-economic model is used to assess the levelized cost of electricity from a plant that integrates solar PV with bio-crude production from pyrolysis and its combustion in an engine. The analysis finds that the LCOE for solar PV and biomass pyrolysis is in the range of 65 to 85 USD/MWh when using woody biomass feedstocks, making the scheme competitive with solar PV and lithium-ion batteries. This article also discusses how the integration of biomass liquefaction with intermittent renewables can aid the development of liquid biofuel value-chains by increasing bio-crude supply and supporting the establishment of biorefineries.

本文就将生物质液化工厂（热解，加氢热解，水热液化，烃类溶剂中的液化等）与间歇性可再生能源（例如风能和太阳能光伏（PV））整合以提供能量存储和支持的机会和挑战提供了观点发展生物燃料生产。技术经济模型用于评估将太阳能PV与热解及其在发动机中燃烧的生物原油生产相结合的工厂的平均电价。分析发现，使用木质生物质原料时，用于太阳能光伏和生物质热解的LCOE在65至85美元/兆瓦时的范围内，使该方案与太阳能光伏和锂离子电池具有竞争力。
