Abstract

This study presents the sequestration and emissions of forests and algae related to CO2 while providing a comparison to other biomass sources (arable crops, short rotation coppices). The goal of the paper is to analyze the impact of the current CO2 balance of forests and the future prospects for algae. Our calculations are based on data, not only from the literature but, in the case of algae, from our own previous experimental work. It was concluded that the CO2 sequestration and natural gas saving of forests is typically 3.78 times higher than the emissions resulting from the production technology and from the burning process. The economic and environmental protection-related efficiency operate in opposite directions. The CO2 sequestration ability of algae can primarily be utilized when connected to power plants. The optimal solution could be algae production integrated with biogas power plants, since plant sizes are smaller and algae may play a role, not only in the elimination of CO2 emissions and the utilization of heat but also in wastewater purification.
