The increasing rate of industrialization and urbanization increases waste and wastewater generation along with global energy demand. That makes the necessity of the current waste treatment and process technologies to be upgraded into the sustainable or green energy generation such as hydrogen production from the waste materials and hydrogen fuel cells-based technologies. Fuel cells are electrochemical devices that use hydrogen as fuel cells for electricity or heat generation. The fuel cells-based technologies are in the infant stage and need to be explored for the vital utilization of hydrogen for the various energy related applications. Stationary application of fuel cells or hydrogen fuel cell vehicles related technologies are hotspot research areas in the 21st century. In this chapter, the authors summarize the recent development of the hydrogen production from waste, current state of the art in hydrogen fuel cells, and hydrogen fuel cell vehicles and their economic and sustainability benefits. It also includes the key challenges of these technologies for commercial applications.

Pre-treatment of fruit, food and vegetable waste materials could enhance the biogas generation and waste stabilization in a shorter time. Effect of alkaline, hydrothermal, thermal and ultrasonication pre-treatment of fruit, food and vegetable waste (FFVW) on the anaerobic co-digestion (ACD) was assessed in terms of total solid (TS), volatile solid (VS) reduction and biogas/methane production. The mesophilic anaerobic co-digestion of pre-treated FFVW with cow dung was performed in a laboratory scale 1L batch digester for 30 days at 40 ± 2 °C temperature. Performance of ultrasonication process is found more economical and efficient pre-treatment over other pre-treatment processes such as thermal, alkaline and hydrothermal processes. Obtained results show that ultrasonication pre-treatment process enhances the biogas and biomethane production by 29.4% and 18.4%, respectively. During ultrasonication pre-treatment, 16.89% TS and 19.44% VS removal are noted. While 106.81 ml biogas/gVS and 29.92 ml CH4/gVS are generated during ACD of ultrasonicated FFVW. In addition, considerable enhancement in biogas production was noted with alkaline pre-treatment but it is least economical. Economic analysis shows that the cost for the production of biogas through anaerobic co-digestion from untreated, ultrasonication, alkaline, hydrothermal and thermal pre-treated FFVW are 2.45, 3.12, 19.33, 5.52 and 22.72 USDs/ton FFVW, respectively. Energy study also indicates the lesser energy consumption and higher biogas production in case of ultrasonication pre-treatment.

Microbial electrolysis cell (MEC) can be utilized for the simultaneous treatment of actual industry wastewater and biohydrogen production. However, efficient and cost-effective cathode, working at ambient conditions and neutral pH, are required to make the MEC as a sustainable technology. In this study, MEC with electrodeposited cathodes (co-deposits of Ni, Ni-Co and Ni-Co-P) were utilized to evaluate the treatment efficiency and hydrogen recovery of sugar industry wastewater. MECs operation was carried out at 30 ± 2 °C temperature in batch mode at an applied voltage of 0.6 V in neutral pH with sugar industry effluent (COD 4850 ± 50 mg L-1, BOD 1950 ± 20 mg L-1) and activated sludge as a source of microorganism. The Ni-Co-P electrodeposit on both cases achieved the maximum H2 production rate of 0.24 ± 0.005 m3(H2) m-3 d-1 and 0.21 ± 0.005 m3(H2) m-3 d-1 with ~50 % treatment efficiency for a 500 ml effluent in 7 days' batch cycles. It was also found that fabricated cathodes can treat real wastewater efficiently with considerable energy recovery than previously reported literature. This study showed the potentiality of the real-time industrial effluents treatment and biohydrogen production near to ambient atmospheric conditions that emphasizes the waste to energy bio-electrochemical system.

Increasing population and rapid urbanization lead to degradation of the natural environment while waste generation and energy crisis are major challenges in the most developing country. Hydrogen is considered one of the most promising energy carriers and capable to replace fossil fuels and meet the world's energy demand and concomitantly reduce toxic emissions. Currently, the world produces around 50 million tonnes/year from the process (i.e., electrolysis of water, steam reforming of hydrocarbons, and auto-thermal processes), but these processes are not sustainable and economical due to energy requirements and waste/pollutants generation. These challenges required growing interest in renewable energy resources such as hydrogen as an energy carrier. Hydrogen production from renewable sources attracted recent research attention because of its potential for sustainability and diversity. Hydrogen can be produced by various thermal, chemical, and biological technologies that include steam reforming, electrolysis, biomass conversion, solar conversion, and biological conversion.

Abstract The development of efficient and economical cathode, operating at ambient temperature and neutral pH is a crucial challenge for microbial electrolysis cell (MEC) to become commercialize hydrogen production technology. In the present work, eight different electrodes are prepared by the electroplating of Ni, Ni–Co and Ni–Co–P on two base metals i.e., Stainless Steel 316 and Copper separately to use as cathode in MEC. Electrodeposited cathode materials have been characterized by XRD, XPS, FESEM, EDX and linear voltammetry. The fabricated cathodes show higher corrosion stability with improved electro-catalytic performance for the hydrogen production in the MECs as compared to the bare cathodes (SS316 and Cu). Data obtained from linear voltammetry and MEC experiments show that developed cathode possess four times higher intrinsic catalytic activity in comparison to bare cathode. Electrodeposited cathodes are intensively examined in membrane-less MEC, operating under applied voltage of 0.6 V in batch mode at 30 ± 2 °C temperature, in neutral pH with acetate as substrate and activated sludge as inoculum. Ni–Co–P electrodeposit on Stainless Steel 316 cathode gives maximum hydrogen production rate of 4.2 ± 0.5 m3(H2)m−3d−1, columbic efficiencies 96.9 ± 2%, overall hydrogen recovery 90.3 ± 4%, overall energy efficiency 241.2 ± 5%, volumetric current density 310 ± 5 Am−3. The net energy recovery and COD removal are 4.25 kJ/gCOD and 61%, respectively. Prepared cathodes show stable performance for continuous 5 batch cycle operations in MEC.

Abstract Recently, nanoparticle-based immobilization of biocatalytic systems is getting interested in bioremediation efficiency. Therefore, green synthesized ZnO ( 2 ( 2+ to immobilize laccase (Lac) through metal affinity adsorption. Nanospheres (∼300 nm) of lac-ZnO and nanoclusters of lac-MnO 2 ( 2 and their activities were doubled than free lac prepared by solid state fermentation. Further, catalytic potential of lac-ZnO and lac-MnO 2 was examined for in vitro degradation of alizarin red S dye in simulated-water. Degradation of dye was highest with lac-ZnO (95%) followed by lac-MnO 2 (85%) and free lac (49%) at initial pH (∼7.0), dye (20 mg/L) and catalyst (50 mg). Control experiment indicated that lac-ZnO was the better catalyst than ZnO and free lac. MnO 2 seemed to enhance stability and activity of lac- MnO 2 over free lac. Moreover, a combination of nanomaterial and enzyme is required for achieving biocompatibility and inert condition without denaturing of the enzyme. Overall, ZnO and MnO 2 are potential for large-scale lac immobilization with improved properties and reuse. Lac-ZnO and lac-MnO 2 may be used as important adsorbents in waste water treatment with a bright future.
