The world is undergoing a population explosion; urbanization has also taken giant leaps with higher standards of people. It is noted that the supply and the demand for energy have not been in correlation with one another, as around. When the supply of energy is scaled up, there will large amounts of emissions released from the power plants. Therefore, it is important to focus on capturing and storage of harmful greenhouse gas emissions, using renewable energy resources, so that emission mitigation can be made in an efficient and economically feasible way. The pragmatic analysis of solar-assisted post-combustion carbon capture (SPCC) has been reviewed upon, where the energy compensation of a coal-fired plant due to regeneration of absorbent has been scrutinized. It is also been compared with the integration of geothermal energy (GTCC) for carbon capture. In the adsorption process, various techno-economic analysis of Carbon Capture and Storage (CCS) integrating solar-assisted temperature swing adsorption has been reported along with the effect of absorbent material in pressure-temperature swing adsorption for CO2 capture. Assessment of solar-assisted CCS are also been accomplished by adopting pliable thinking on the energy system. Finally, the integration with solar thermal power plant using novel Sodium Carbonate as a solvent is discussed. Thus, several parts of the CCS system have been construed with renewable energy towards the goal of zero-emission power generation, which seems highly impossible, can be harnessed by 2050
With the increase in usage of bio-products of all sorts in the modern world, the waste obtained during the production phases has been a major concern for over a period of time. The accumulation of these wastage not only enhances various kinds of pollution, but also increases the carbon footprint. Considering these negative impacts brought about by poor maintenance of these wastages and advancements in the field of utilization of sustainable and renewable energy, it is very important to produce bio-hydrogen due to the limitations of using industry-produced hydrogen. Hydrogen, though having many advantages, like being environmentally friendly and highly efficient when used as a fuel, has been neutralized by certain drawbacks such as production of it in industrial set up is found to be expensive and the storage process is tedious because of its flammable nature. Therefore, production of bio-hydrogen is found to be vital. In our paper, we have touched upon various methods of preparation of bio-hydrogen from the by-products of the farms such as corn stover, corn straw and rotten apple. Production of bio-hydrogen from micro algae has also been stressed upon as it has been found be one of the most efficient method. But, most of the analysis has been done on corn stover based on ambient atmospheric conditions, factors that affect the process and comparison between photo fermentation, dark photo fermentation and dark fermentation has also been judged as an important criterion for enzyme saccharification. Another important method of production of production of hydrogen using tequila vinasses in presence of charcoal by dark fermentation process has also been reviewed in this paper
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
