Algae Bioenergy: A New Power Source for Sustainable Development

Abstract

Algae bioenergy is a kind of bioenergy made of algae as raw materials, which can replace liquid fossil fuels. Meanwhile, algae is also a substitute for common biofuel raw materials such as corn ( Zea mays ) and sugarcane ( Saccharum officinarum ). At present, many governments and private enterprises in countries have begun to study how to reduce the production cost of algae bioenergy for commercial applications. Like fossil fuels, algae bioenergy also produces carbon dioxide during combustion, but unlike fossil fuels, algae can absorb natural carbon dioxide through photosynthesis during their growth process. Therefore, using algae bioenergy can achieve carbon dioxide reduction. This review introduces the species of algal bioenergy, analyzes its sustainability, future application and development trend, so as to better understand its potential and limitations.
