Aquatic plants have been considered as a cause for concern because they impede aquatic flora and fauna. However, biofuel production from aquatic plants is an emerging energy source. As a consequence, this paper presents a detailed review of bio‐fuel production from floating aquatic plants with their physicochemical properties. The main focus of this study is to evaluate the biofuel production potential of some major aquatic plants. This paper also presents some methods for biofuel production from aquatic plants that are feasible for future energy generation. Five major types of floating aquatic plants are analyzed in this study, viz. Azolla, water hyacinth, water fern, water lettuce, and duckweed, with their related biofuel production methodologies such as transesterification, pyrolysis, hydrolysis, and torrefaction. This paper also evaluates optimum bio‐fuel production conditions for aquatic plants and their upgradation methodologies. Conventional fuel and aquatic bio‐fuel properties are also compared in this study. Findings suggest that, depending on calorific value and viscosity, Azolla and water fern (Salvania molesta) are better aquatic plants to generate high‐quality (similar to diesel) biofuels compared with other aquatic plants. Bio‐fuel production from water fern, water lettuce, and duckweed are also comparatively less focused sources of energy. The cost associated with cleaning invasive aquatic plants from water can be turned into an investment by producing biofuel from aquatic plants using sustainable techniques. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

浮游水生植物生物燃料生产的回顾：一种生物可再生能源的新兴来源

由于水生植物阻碍了水生植物和动物群，因此被认为是引起人们关注的原因。但是，水生植物生产生物燃料是一种新兴的能源。因此，本文详细介绍了浮动水生植物的生物燃料生产及其理化特性。这项研究的主要重点是评估一些主要水生植物的生物燃料生产潜力。本文还提出了一些从水生植物生产生物燃料的方法，这些方法可用于未来的能源生产。本研究分析了五种主要的漂浮水生植物，即。Azolla，水葫芦，蕨类植物，莴苣和浮萍及其相关的生物燃料生产方法，例如酯交换，热解，水解和焙干。本文还评估了水生植物的最佳生物燃料生产条件及其升级方法。在这项研究中还比较了常规燃料和水生生物燃料的性质。研究结果表明，根据热值和粘度，满江红和水蕨（Salvania molesta）是比其他水生植物更好的水生植物，可生产高质量（类似于柴油）生物燃料。蕨类植物，水生菜和浮萍的生物燃料生产也是相对较少集中的能源。通过使用可持续技术从水生植物生产生物燃料，可以将与清洁入侵性水生植物的水相关的成本转化为投资。©2021化学工业协会和John Wiley＆Sons，Ltd
