“…The technologies developed to exploit renewable energies are known as renewable energy technologies (RET) or clean technologies or green energy. Sustainable economic and industrial growth also requires safe and sustainable energy resources [47][48][49]. Maximizing resource (material and energy) recovery and minimizing environmental impacts such as contribution to the global warming are important objectives in the solid waste management (SWM) sector, which is considerably developed over the past century [50,51].…”

The production of biogas via anaerobic digestion (AD) provides significant benefits over other techniques of bioenergy production. Biogas consists of several undesired components, such as H2S, CO2, nitrogen, hydrogen, oxygen, and water vapor, which contribute to lower the calorific value when compared with natural gas. The pollutants founded in low concentration effects the biogas commercial application in large scale, and therefore it must be taken out before usage. Various cleaning and upgrading techniques to improve the quality of raw biogas are discussed and categorized into physiochemical and biological technologies. Advanced techniques, such as hydrate separation, cryogenic separation, biological methods, membrane enrichment, in-situ upgrading, multistage and high-pressurized anaerobic digestion, represent the modern developments in biogas upgrading techniques. Biogas is a renewable green source of energy, and presently, it is utilized in a lot of developing countries as an alternative and energy renewable source for a broad range of applications. Most countries are in the process of instituting legislation to regulate the biogas industry. Biogas is considered to be the future of renewable and sustainable energy.

“…All these challenges eventually forced our scientists and researchers to ex-plore a clean, renewable, sustainable, cheap energy source that can act as a replacement for fossil fuels (Srivastava et al, 2021). A source of energy which could eventually find the balance between economic development and environmental sustainability (Prasad et al, 2019). Currently, much effort is being put into searching for one such substitute.…”

As the energy demand is continuously rising with the increase in population, the use of fossil fuels is also increasing at the same rate. These fossil fuels release greenhouse gases (GHG) which are harmful to human health and our environmental health and these fuels are also expected to exhaust in the near future. This eventually has led to an emerging need to shift to a more reliable, sustainable, clean energy source. Biohydrogen as fuel is a potential alternative, as hydrogen has proved to be one such fuel which has the potential to replace fossil fuels. There is a need to produce it in a clean, sustainable way to compete with the fuels that are being used currently. The hydrogen which is produced biologically is known as biohydrogen. Microorganisms also play a huge role in the process of hydrogen generation by virtue of their natural mechanism. Hydrogen can be produced biologically using approaches like biophotolysis (direct and indirect), fermentation (dark and photo) and microbial electrolysis cell (MEC). Among all, dark fermentation seems to be the most efficient when compared to other procedures. The challenges currently being faced with this technology are the yield of hydrogen, the high cost of the reactor and system efficiency. This technology still needs a lot of research and improvement to replace fossil fuels entirely.

“…The domestic production and use of renewable energy from biomass, solar, hydro, wind, geothermal, and marine are expected to perform significant roles in energy supplies. 6 It has been reported that the share of renewable energy in the total primary energy supply will rise from 14% in 2015 to 63%, where bioenergy from biomass resources alone would account for approximately two-thirds in 2050. 7 Further, bioenergy supply will increase to 2−6 times by improving biomass conversion processes and usage.…”

The burning of a huge amount of nonrenewable fossil fuel has unfavorable consequences on the environment, climate, and living beings. The application of renewable bioenergy resources is considered an eco-friendly and sustainable substitute for fossil fuels. Biomass as a renewable resource has gained tremendous attention due to its potential to produce bioenergy in the form of solid, liquid, and gaseous fuels for running internal combustion engines in transportation, industries, and heat and electricity generation. This review critically examines the potential of biomass resources, scope, and technological advances in converting biomass to bioenergy. It also discusses the challenges, opportunities, energy policies, and prospects of biomass conversion to bioenergy within global and Indian contexts. Currently, several novel physical, chemical, and biological routes are used to produce renewable bioenergy. In India, crop biomass availability is estimated at around 500 million metric tons per year and can produce energy equivalent to 18,000 megawatts. It shows a bright future in energy production in India if adequately used.
