“…Vinicio et al (Oro, de Oliveira, and Bazzo 2018) used the waste heat from a PEMFC to operate a chemisorption chiller, using sodium bromide impregnated in expanded graphite as the adsorbent and ammonia as refrigerant. A thermosiphon acted as the heat reservoir to decrease the temperature drop in the PEMFC stack and to integrate the thermal energy between the chemisorption system and the PEMFC.…”

Hydrogen has the potential to be the sustainable fuel of the future, decrease the global dependence on fossil fuel resources, and lower the pollutant emissions from the transportation industry. In this study, recent development in hydrogen-based transportation engines is reviewed to scrutinize the feasibility of using hydrogen as a major fuel of future. Using hydrogen in internal combustion engines achieves only 20-25% efficiency and low power output compared to fossil-fueled internal combustion engines. Although hydrogen-based internal combustion engines have recently received considerable interests, several practical barriers have prevented the fast development of this technology. Hence, at the current stage, using hydrogen as an additive to hydrocarbon fuel systems have been taken into consideration to produce higher performance than hydrogen-only internal combustion engines. Using the dual-fuel strategy can increase the combustion stability and thermal efficiency while decreasing the CO and unburned hydrocarbons emissions, and fuel consumption. Alternatively, hydrogen can be used in fuel cells for vehicular applications with several automotive manufacturers producing fuel cell vehicles currently. Fuel cells can achieve efficiencies of up to 60%, while the rest is lost as heat. Strategies that have been investigated to increase the efficiency, performance, and lifespan of fuel cells are capillary pumping systems, a chemisorption chiller, nanofluids and supercapacitors. All such strategies improved the fuel cells in one or more ways. Safety, hydrogen delivery, onboard storage, and the capital and operating costs of hydrogen powered vehicles are analyzed to approach to clean transportation utopia.

“…For thermochemical heat pumps, the COP is below one. Nevertheless, some studies have focused on system efficiency and considered fuel efficiency in laboratory experiments, leading to system efficiencies of 60% or more [16][17][18]. Fuel cells are used for the trigeneration of electricity, heating, and cooling in hot climates.…”

Tropical climate is characterized by hot temperatures throughout the year. In areas subject to this climate, air conditioning represents an important share of total energy consumption. In some tropical islands, there is no electric grid; in these cases, electricity is often provided by diesel generators. In this study, in order to decarbonize electricity and cooling production and to improve autonomy in a standalone application, a microgrid producing combined cooling and electrical power was proposed. The presented system was composed of photovoltaic panels, a battery, an electrolyzer, a hydrogen tank, a fuel cell, power converters, a heat pump, electrical loads, and an adsorption cooling system. Electricity production and storage were provided by photovoltaic panels and a hydrogen storage system, respectively, while cooling production and storage were achieved using a heat pump and an adsorption cooling system, respectively. The standalone application presented was a single house located in Tahiti, French Polynesia. In this paper, the system as a whole is presented. Then, the interaction between each element is described, and a model of the system is presented. Thirdly, the energy and power management required in order to meet electrical and thermal needs are presented. Then, the results of the control strategy are presented. The results showed that the adsorption cooling system provided 53% of the cooling demand. The use of the adsorption cooling system reduced the needed photovoltaic panel area, the use of the electrolyzer, and the use of the fuel cell by more than 60%, and reduced energy losses by 7% (compared to a classic heat pump) for air conditioning.

“…In regard to the heat recovery in fuel cells, adsorption systems [119] show promising prospects in terms of both electrical and cooling energy cogenerations. According to the Reference [119], the heat recovery efficiency can be further enhanced with respect to higher power outputs and shorter cycle times of the fuel cell.…”

Clean power production, buildings, and transportation are key areas for climate change mitigation. Their tighter integration decreases not only the emissions, but also the energy consumption of buildings and transportation.Energy integration and interactions between buildings and vehicles are dependent on the type of building, vehicle, and renewable energy system, as well as the local climatic conditions. The current academic literature does not provide a systematic analysis of this topic. In the study, different energy management systems and advanced energy control strategies have been formulated to study such interactions both from a building and a vehicle perspective. Furthermore, technical solutions have been systematically reviewed in terms of the enhancement of energy interaction capabilities, in particular from the standpoint of renewable energy systems, energy/fuel charging facilities, and control strategies. Assessment criteria employed in the review of solutions include grid interaction, annual operational cost, annual net CO2 emissions, and annual matching capability. The literature review identifies several technical challenges that need further consideration such as capacity expansion and power fluctuation of the electric grid, low efficiency of heat recovered from electricity generation, and depreciation of vehicles. The future outlook and potential for the energy interaction networks between buildings and vehicles have also been presented.
