Carbon capture and sequestration technologies are used to reduce carbon emissions. Membranes, solvents, and adsorbents are the three major methods of CO capture. One of the promising methods is the use of algae to absorb CO from flue gases and convert it into biomass. Algae have great potential as renewable fuel sources and CO capture using photosynthesis for carbon fixation has also attracted much attention. This paper presents an extensive and in-depth report on the utilization of algae for carbon capture and accumulation. This is done in conjunction with cultivating the algae for the production of biomass for biodiesel production. Different systems are investigated for algae cultivation as well as carbon capture to effectively mitigate carbon emissions. The performance and productivity of these biosystems depend on various conditions including algae type, light sources, nutrients, pH, temperature, and mass transfer. Macroalgae and microalgae species were explored to determine their suitability for carbon capture and sequestration, along with the production of biodiesel. The steps for producing biodiesel were comprehensively reviewed, which are harvesting, dehydrating, oil extraction, oil refining, and transesterification. This technology combines active carbon capture with the potential of biodiesel production.
碳捕集和封存技术用于减少碳排放。膜、溶剂和吸附剂是 CO 捕集的三种主要方法。一种有前途的方法是利用藻类从烟道气中吸收 CO 并将其转化为生物质。藻类作为可再生燃料来源具有巨大的潜力，而光合作用固定 CO 用于碳捕集也引起了广泛关注。本文对藻类用于碳捕集和积累的利用进行了广泛而深入的报告。这是与培养藻类生产生物柴油生产的生物质同时进行的。研究了不同的系统用于藻类培养以及碳捕集，以有效减少碳排放。这些生物系统的性能和生产力取决于各种条件，包括藻类类型、光源、营养物质、pH 值、温度和质量传递。探索了大型藻类和微藻类物种，以确定它们在碳捕集和封存以及生物柴油生产方面的适用性。全面回顾了生产生物柴油的步骤，包括收获、脱水、油提取、精炼和酯交换。该技术将活性碳捕集与生物柴油生产的潜力结合在一起。
