“…The results suggested that the entire energy needs of the school may be satisfied by the plant with optimal planning. Assaf and Shabani[135] presented a transient analysis of a stand-alone solar-hydrogen CHP plant for a remote household in Australia. The plant included a solar PV array, solar thermal collectors, an electrolyser, a fuel cell, a hydrogen storage tank, and one or two water storage tanks.…”

“…On the other hand, along with having high gravimetric energy density and no self-discharge problem, power and energy supply duration are set independently in hydrogen fuel cell systems. That makes hydrogen-based energy storage system one of the promising technologies favourable for long-term large-scale energy storage applications [6,39,40]. While receiving rapidly-growing attention, hydrogen-based energy storage solutions for such applications areas yet to be further developed.…”

“…The excess from the renewable sources (i.e., solar and wind) is directed towards an electrolyser to generate hydrogen by electrolysing water into hydrogen and oxygen. The hydrogen is stored in the storage tank and when the renewable sources fall short in meeting the demand, the fuel cell draws on this stored hydrogen and generates electricity (usually by taking oxygen from air) [6,7].…”

This paper presents a case study of using hydrogen for large-scale long-term storage application to support the current electricity generation mix of South Australia state in Australia, which primarily includes gas, wind and solar. For this purpose two cases of battery energy storage and hybrid battery-hydrogen storage systems to support solar and wind energy inputs were compared from a techno-economical point of view. Hybrid battery-hydrogen storage system was found to be more cost competitive with unit cost of electricity at $0.626/kWh (US dollar) compared to battery-only energy storage systems with a $2.68/kWh unit cost of electricity. This research also found that the excess stored hydrogen can be further utilised to generate extra electricity. Further utilisation of generated electricity can be incorporated to meet the load demand by either decreasing the base load supply from gas in the present scenario or exporting it to neighbouring states to enhance economic viability of the system. The use of excess stored hydrogen to generate extra electricity further reduced the cost to $0.494/kWh.

“…Among these systems the photo thermal conversion technology stays the most varied within all, however depending on the classical form of the radiation conversion isn't enough to assure the good function of the systems heated [2]. Hence optimization approaches are used [3,4] .In the literature, several works have been published on multiple optimization methods for solar heating systems [3]. Authors started by determining the optimal control strategy for water flow modulation in solar thermal applications using as a starter differential algorithm based on the switch on switch off principal (between 0 and a maximum value of flow rate) [1,5] , thus the controller either starts or shuts down the water flow pump according to the switch on switch off temperature difference.…”

The use of solar thermal energy is getting more attention throughout the past few years, providing alternative yet efficient solutions to the energy production challenge across the globe. Solar thermal collectors are one of the most diversified types of the solar collectors' family, starting from one simple principle: heating water from the sun. The technology used in this area is simple yet reliable. The collector used in the project is a photo thermal converter; the solar radiations are captured by the solar cells, heating the water inside a serpentine and transferring it to the reservoir. The photo thermal collector is illuminated by a laboratory lamp of 277, 42 Watts (extracted power) and heats the water up to 39°C in 15minuts. The aim of this work is to study different theories to realize a monitoring and a control approach to uphold the temperature of the reservoir in a specified range and establish better productivity of the system. Therefore, we added two Arduino-based devices, one to monitor temperature, and the other to control the water pump speed based on the values detected from the temperature sensors. The temperature of the water in the reservoir is maintained in the desired range (30°C to 40°C). The communication between the computer and the system in a total is done by serial data transfer.
