In recent years, many researchers have tested compression ignition engines with the goal of creating a diesel fuel alternative. This was also published in literature. The limited supply and increased cost of petroleum products are two main reasons for the search for alternate feedstocks for biodiesel. This paper reviews the potential of alternative biodiesel feedstocks to replace petroleum diesel, specifically focusing on algae biodiesel and the process for producing biodiesel. To better understand the properties of various types of biodiesels, a table comparing the properties of different types of biodiesels is also presented. The comprehensive analysis shows that biodiesel from algae is a potential alternative fuel. Petroleum is a complex mixture of chemical compounds extracted from crude oil and processed in oil refineries into a variety of petroleum products that are used as fuel for a variety of applications.
Furthermore, the rising demand for energy worldwide, along with the harmful environmental effects linked to the use of fossil fuels, has driven increased interest in clean and renewable energy sources. Biodiesel derived from a variety of biological sources has become increasingly important due to its eco-friendly nature. It can also be used in conventional diesel engines without requiring significant modifications. Among the available feedstocks, algae are particularly promising due to their high oil content and the fact that they do not compete significantly with food crops for land. In addition, growing algae can help absorb carbon dioxide, which adds to its environmental advantages.Despite these benefits, there are still several challenges that need to be overcome before algae biodiesel can be widely adopted. These include high production costs, limitations in current technology, and difficulties in scaling up production to industrial levels. Ongoing research is focused on improving methods of algae cultivation, harvesting, and fuel conversion to make the process more efficient and cost-effective. As these technologies continue to develop, algae-based biodiesel has the potential to become a reliable and sustainable alternative to traditional fossil fuels, helping to reduce pollution and decrease reliance on non-renewable energy sources.
