Algae a promising energy reserve due to its adaptability, cheap source, sustainability and it's growth ability in wastewater with efficient sequestration of industrial carbon dioxide. This review summarizes the pathways available for biofuel production from carbon sequestered algae biomass. In this regard, this review focuses on microalgae and its cultivation in wastewater with CO sequestration. Conversion of carbon sequestered biomass into bio-fuels via thermo-chemical routes and its engine emission properties. Energy perspective of green gaseous biofuels in near future. This review revealed that algae was the pre-dominant CO sequester than terrestrial plants in an eco-friendly and economical way with simultaneous wastewater remediation. Hydrothermal liquefaction of algae biomass was the most preferred mode for biofuel generation than pyrolysis due to high moisture content. The algae based fuels exhibit less greenhouse gases emission and higher energy value. This review helps the researchers, environmentalists and industrialists to evaluate the impact of algae based bio-energy towards green energy and environment.
藻类由于其适应性、廉价的来源、可持续性以及在废水中生长的能力和对工业二氧化碳的有效隔离，是一种很有前途的能源储备。本文综述了从碳隔离藻类生物质生产生物燃料的可用途径。在这方面，本文重点介绍了微藻及其在废水和 CO 隔离中的培养。通过热化学途径将碳隔离生物质转化为生物燃料及其发动机排放特性。在不久的将来，绿色气态生物燃料的能源前景。本文综述表明，藻类是一种比陆地植物更具优势的 CO 隔离物，它以生态友好和经济的方式，同时进行废水修复。与热解相比，由于水分含量高，藻类生物质的水热液化是最受欢迎的生物燃料生成方式。藻类燃料的温室气体排放量较低，能量值较高。这篇综述有助于研究人员、环保主义者和工业家评估基于藻类的生物能源对绿色能源和环境的影响。
