Hydrogen production for energy: An overview

A review on dark fermentative biohydrogen production from organic biomass: Process parameters and use of by-products

This paper presents a review of the turn of events and points of view of biogas in and its utilization for power, heat and in transport in the European Union (EU) and its Member States. Biogas creation has expanded in the EU, empowered by the sustainable power strategies, notwithstanding monetary, ecological and atmosphere benefits, to arrive at 18 billion m3 methane (654 PJ) in 2015, speaking to half of the worldwide biogas creation. The EU is the world chief in biogas power creation, with more than 10 GW introduced and various 17,400 biogas plants, in contrast with the worldwide biogas limit of 15 GW in 2015. In the EU, biogas conveyed 127 TJ of warmth and 61 TWh of power in 2015; about half of absolute biogas utilization in Europe was bound to warm age. Europe is the world's driving maker of biomethane for the utilization as a vehicle fuel or for infusion into the petroleum gas network, with 459 plants in 2015 creating 1.2 billion m3 and 340 plants taking care of into the gas network, with a limit of 1.5 million m3. Around 697 biomethane filling stations guaranteed the utilization 160 million m3 of biomethane as a transport fuel in 2015.

Biogas Developments and Perspectives in Europe

Recent advances in liquid biofuel production from algal feedstocks

Production of biohydrogen has the potential to be a renewable alternative to current technologies. There are varieties of technologies for biological hydrogen production mechanisms including biophotolysis, photo fermentation, dark fermentation and hybrid biohydrogen production by electrochemical processes. In these studies, a review on the recent developments of biohydrogen production is presented. First, the theoretical principles of biophotolysis by cyanobacteria and green micro algae, as well as direct and indirect of biophotolysis process on hydrogen production are described. Secondly, practical aspects and fundamental of biological hydrogen production processes by photo and dark fermentation are reviewed. This work also involved comparison of the maximum H2 yield, bacterial strains, operating condition, suitable substrates, and mathematical models for fermentative hydrogen production. A new hybrid biological hydrogen production processes by using the electrochemical process is then proposed. This study can also be used to improve the basic and current knowledge about the performance of the biophotolysis, fermentative and electrochemical process in producing hydrogen gas as the alternate fuel.

Hydrogen is considered as an ideal alternative to fossil fuels due to its high energy density by mass and clean combustion product. Using anaerobic bacteria to ferment biomass and produce renewable hydrogen is receiving increased attention. Aquatic algal biomass, which can be sourced from natural algal bloom or mass cultivation, is considered as a promising substrate for hydrogen fermentation. This paper reviews the recent developments in fermentative hydrogen production from algal biomass, with the main focus on hydrogen production potential and its current technological state. The stoichiometric hydrogen yields of algal biomass in dark fermentation are predicted based on the theoretical contents of monosaccharides from carbohydrates and glycerol from lipids in biomass. Hydrogen yields of algal biomass by dark fermentation can be improved by using efficient pretreatments at optimized biomass carbon/nitrogen ratios with domesticated hydrogen-producing bacteria as the inoculum. The effluent of dark fermentation, which is rich in volatile fatty acids, should be used for the production of biofuels and biochemicals to further improve the energy efficiency and economic feasibility of hydrogen fermentation.
