Opis:: Many new zero-emission propulsion technologies are being developed today due to the need to reduce the atmospheric carbon dioxide emissions. The impact of the transport sector on the environment drives a need for innovation, including innovation in the rail transport sector specifically. At the TRAKO fair of rail vehicles the newest technological solutions have been presented. These new vehicles are expected to take over the rail transport sector in the coming decades. Many of the presented solutions and prototypes focused on using hydrogen as fuel for a system of hydrogen fuel cells, which are then used to produce the electricity needed to drive the vehicle. The development of hydrogen fuel technologies in vehicle drives in recent years allowed for a set of new solutions to appear for all types of rail vehicles and applications. Hydrogen powered rail vehicles for transporting cargo, passengers, and shunting vehicles have been shown. This article provides a discussion of the newest hydrogen solutions and vehicles sent to the market. It was determined that the adoption of such solutions will be mainly restricted by the relative cost of the hydrogen fuel rather than the vehicles or fuel cell technologies themselves. The cost of hydrogen production, when powered by renewable Energy sources to enable reduced carbon dioxide emissions, would need to be reduced to at least $2.50 /kg of fuel in order to satisfy the requirements for widespread adoption.

Opis:: Electricity generation from swine wastewater using microbial fuel cell (MFC) was investigated Swine wastewater was collected into a dual-chambered (aerobic and anaerobic) fuel cell. The maximum power output using copper and carbon electrodes were 250.54 and 52.33 μW, respectively, while 10.0 and 5.0 cm salt bridge length between the cathode and anode gave maximum power outputs of 279.50 and 355.26 μW, respectively. Cathodic potassium permanganate and distilled water gave maximum power outputs of 1287.8 and 139.18 μW, respectively. MFCs utilized microbial communities to degrade organic materials found within wastewater and converted stored chemical energy to electrical energy in a single step. The initial bacterial and fungal counts were 7.4×10⁶ and 1.1×10³ CFU ml^-1. Bacterial counts steadily increased with time to 1.40×10⁷ CFU ml^-1 while fungal count declined to 4.4×106 CFU ml-1 after day 60. The decline in microbial counts may be attributed to the time necessary for acclimatization of microbes to the anode. The genera identified were Bacillus, Citrobacter, Pseudomonas, Lactobacillus, Escherichia coli, Aspergillus and Rhizopus. These microbes acted as primary and secondary utilizers, utilizing carbon and other organics of the wastewater. Chemical parameters indicated that the biochemical oxygen demand decreased from 91.4–23.2 mg/L, giving 75% while the chemical oxygen demand ranged from 243.1–235.2 mg/L, representing 3.3% reduction. Although, the metabolic activities of microbes were responsible for the observed degradation, leading to electricity, the overall power output depended on the distance between the anode and cathode ompartments, types of electrode materials and mediators and oxygen reaction at the cathode.

Opis:: Providing more and more energy is an essential task of today's energetic industry. In the last few years, addition to traditional methods of energy production, alternative energy sources have been fast developing. One of the devices that can use these sources is fuel cell. The fuel cells can be a power source of future mainly due to their high efficiency, low influence on environment and possibility of powering with different fuels. Most often fuel cells are powered by hydrogen. However, problems with the problems with its cheap production and storage are the reason for the search of new fuels for fuel cells. But it must be a fuel that will provide zero or low emission level. One of these fuels can be vegetable oil. The paper presents measurements of electrooxidation of coconut oil emulsion on a smooth platinum electrode in an aqueous solution of KOH. Electrochemical measurements were performed in a glass cell with AMEL System 5000 potentiostat. The obtained maximum current density is equal 25 mA/cm². So, a fundamental possibility of using the coconut oil as fuel for fuel cell. But is necessary to keep the temperature of process above 303K.

Opis:: With the increasing standard of living, energy consumption increases as well. So, waste production, including wastewater, increases as well. One of the types of wastewater is wastewater from yeast industry. Wastewater from this industry has not only a high pollutants load but it is produced in great amounts as well. Technical devices that can accomplish the wastewater treatment and electricity production from wastewater is a microbial fuel cell. In microbial fuel cells activated sludge bacteria can be used for electricity production during wastewater treatment. The possibility of using the Cu-B alloy as cathode catalyst for microbial fuel cells to wastewater treatment of wastewater from yeast industry is presented in this paper. The reduction time for COD with the use of microbial fuel cell with the Cu-B catalyst (with 5, 10 and 15% amount of B) is similar to the reduction time with aeration. The obtained power (4.1 mW) and the amount of energy (0.93 Wh) are low. But, if one can accept a longer COD reduction time, the obtained amount of energy will allow elimination of the energy needed for reactor aeration.

Opis:: There is a real need to use various efficient energy supply systems that are not aggressive towards the global environment. Hydrogen has been seen in different research papers presented in the literature as an essential fuel to generate energy in various energy storage systems. As it is well-known, it is possible to generate renewable electricity using electrolysis. The hydrogen produced can be sold as fuel for various systems, most notably its use in solid oxide fuel cells and a host of modern applications today. Current low-temperature fuel cells are ideal for hydrogen operation, but are not suitable for hydrogen mixtures. In this article, a mathematical analysis was carried out to generate electrical energy in a fuel cell, fed with synthesis gas from the residual biomass gasification process; the primary interest was the generation of electrical energy, solid oxide fuel cell (SOFC), which operate at the temperature of the gas at the outlet of the gasifier were analyzed. The practical efficiency obtained and the theoretical results of the SOFC operation were shown.

Opis:: Microbial fuel cells (MFCs) pertain to a kind of modern technology for the direct conversion of chemical energy in organic matter from wastewaters into electricity during the oxidation of organic substrates. A system of continuous MFC was constructed for the treatment of real petroleum refinery wastewater (PRW). The treatment of real PRW, operational performance of the MFC system, biodegradation of furfural, and energy output were investigated in this study. The MFC was inoculated by mixed anaerobic bacteria, with Bacillus sp. as the dominant type, and continuously operated for 30 days. The biodegradation of furfural and phenol, which are the most prevalent toxicants in refinery wastewater, was investigated. The MFC system reached maximum energy outputs of 552.25 mW/m3 and 235 mV. In the anodic chamber, the maximum removal of furfural and phenol was higher than 99%, with biodegradation of organic content reaching up to 95%. This study demonstrated the viability of a continuous-flow MFC system as a green technology for the treatment of furfural-rich real refinery effluents while generating electricity.

Opis:: Renewable energy application is gaining a wide acceptance by end users; however, considering the fact that renewable energy is intermittent, variable and cannot be predicted, the need of storage systems is becoming a necessity at both micro and macro levels. Fuel cell technology is one of the most promising storage systems due to the fact that hydrogen has high energy density. This paper presents a design of stand-alone PV-PEMFC hybrid system for a small house under Amman climate. The simulation results show that the optimal size of PV array, fuel cell (PEMFC), inverter, electrolyzer (ELE) and H₂ Tank capacity were 10 kW, 1 kW, 5 kW, 6 kW, and 5 kg respectively. Hydrogen proved itself as a low carbon energy source, which is environmental friendly and characterized with high energy content per unit mass. Due to fuel cells technology, hydrogen can be used for inter-season storage.

Opis:: The possibilities of simultaneous removal of sulfates and heavy metals (Cu, Ni, Zn) from acid mine drainage have been investigated in two-section bioelectrochemical system (BES). The used BES is based on the microbial sulfate reduction (MSR) process in the anode zone and abiotic reduction processes in the cathodic zone. In the present study, the model acid mine drainage with high sulfate (around 4.5 g/l) and heavy metals (Cu2+, Ni2+ and Zn2+) content was performed. As a separator in the laboratory, BES used an anionic exchange membrane (AEM), and for electron donor in the process of microbial sulfate reduction in the bioanode zone – waste ethanol stillage from the distillery industry was employed. In this study, the possibility of sulfates removal from the cathodic zone was established by their forced migration through AEM to the anode zone. Simultaneously, as a result of the MSR process, the sulfate ions passed through AEM are reduced to H2S in the anode zone. The produced H2S, having its role as a mediator in electron transfer, is oxidized on the anode surface to S0 and other forms of sulfur. The applicability of waste ethanol stillage as a cheap and affordable organic substrate for the MSR process has also been established. Heavy metals (Cu2+, Ni2+ and Zn2+) occur in the cathode chamber of BES in different degrees of the removal. As a microbial fuel cell (MFC) operating for 120 hours, the reduction rate of Cu2+ reaches 94.6% (in waste ethanol stillage) and 98.6% (in the case of Postgate culture medium). On the other hand, in terms of Ni2+ and Zn2+, no significant decrease in their concentrations in the liquid phase is found. In the case of microbial electrolysis cell (MEC) mode reduction of Cu2+– 99.9%, Ni2+– 65.9% and Zn2+– 64.0% was achieved. For 96 hours, the removal of sulfates in MEC mode reached 69.9% in comparison with MFC mode – 35.2%.
