A group of researchers and their team (Zhao et al .) from various Universities ( Tsinghua University, China, Southeast University, China, Columbia University, New York, Imperial College London, and The Ohio State University, USA) have surveyed a review on biomass-based chemical loops, its good, bad, and future aspects. Zhao et al ., have discussed the biomass, which is considered to be one of a promising renewable energy resource owing to its high moisture content, low energy density, and complex ash components. Biomass is a major energy source, it is considered to be a carbon-neutral renewable and abundant energy resource. The use of carbon in biomass for energy production, which was obtained from atmospheric CO 2 , is considered to be a carbon-neutral fuel. When this biomass is combined with carbon capture technology, then the overall energy conversion progress will be in negative in terms of net CO 2 emission, which is to be termed as BECCS (bioenergy with carbon capture and stora...
