Fossil fuels are being replaced with renewable energy resources (biomass and biomass waste, solar, geothermal, wind, etc.) to ensure sustainable development, reduce the dependence on fossil fuels, address environmental challenges including climate change. Today, biomass produces 5 × 10¹⁹ kJ of energy/year, which corresponds to 10% of the annual global energy consumption. Considering the variety of biomass resources, this value is predicted to reach 150 × 10¹⁹ kJ by 2050. Biomass may become even more important for use as an energy resource and chemical raw material in the 21st century. Hydrothermal biomass conversion stands out as a promising and alternative technology. Methods such as traditional gasification and pyrolysis require dry biomass. Hydrothermal techniques have been developed to eliminate the cost and time required for drying biomass. The purpose of this process is to decompose biomass with a high moisture content into small molecules and reduce its oxygen content to obtain liquid fuels or valuable chemicals. This review presents the current and future state of energy, energy sources, biomass properties and biomass conversion technologies with a focus on hydrothermal technologies.

来自生物质的可持续能源和燃料：以水热生物质加工为重点的综述

化石燃料已被可再生能源（生物质和生物质废物，太阳能，地热能，风能等）替代，以确保可持续发展，减少对化石燃料的依赖，应对包括气候变化在内的环境挑战。如今，生物质每年产生5×10 ¹⁹ kJ的能量，相当于全球年度能源消耗的10％。考虑到生物质资源的多样性，该值预计将达到150×10 ¹⁹到2050年将达到千焦耳。在21世纪，生物质作为能源和化学原料的使用可能会变得更加重要。热液生物质转化是一种有前途的替代技术，脱颖而出。传统的气化和热解等方法需要干燥的生物质。已经开发了水热技术以消除干燥生物质所需的成本和时间。该过程的目的是将水分含量高的生物质分解为小分子，并降低其氧含量，以获得液体燃料或有价值的化学物质。本文以水热技术为重点，介绍了能源，能源，生物质特性和生物质转化技术的当前和未来状态。
