“…Study conducted for the rural and semi-urban northern part of Nigeria suggests that decentralized hybrid systems are a better and cheaper option in long run compared to diesel generators [21]. The foreseeable limitations and possibilities associated with the hybrid mini-grids have been highlighted in different literatures [22][23][24][25][26][27][28][29][30][31]. Only a few works [32][33][34][35][36][37] exist in this field in Bangladesh and the limitations and possibilities of hybrid mini grids are still to be explored.…”

Abstract:Lack of access to energy is considered as a serious bottleneck for the socio-economic development of Bangladesh. Despite earning recognition for promoting solar home systems, most of the rural areas and remote islands of the country still remain non-electrified due to very high unit cost and low quality of electricity from solar home systems (SHS) coupled with only few hours of restricted usages in the evening. Considering the resource potential and demand characteristics at the local level, the present study investigates the hybrid renewable mini-grid approach as a possible solution for universal electricity access in the country. Using Hybrid Optimisation of Multiple Energy Resources (HOMER) simulation model, the study, covering the whole coastal region of Bangladesh, shows that it is possible to offer a much better quality electricity for 12 h to 18 h a day for as low as USD 0.29-USD 0.31/kWh. Hybrid models suggested in this study can be replicated along the coastal belt and remote islands to obtain maximum diffusion of this technology and hence universal electrification.

“…Solar power or wind power alone can fluctuate, however, when they are used together, they can provide a reliable source of energy. Thus, an ideal solution is to combine these two forms of energy sources to create a constant energy flow (Dalwadi et al, 2011).…”

A very significant development in the global airport industry in recent times has been the introduction and use of green renewable energy systems, such as solar and wind powered hybrid systems. Airports are very energy intensive and have a significant carbon footprint. Thus, the use of renewable green energy is enabling airports to reduce their carbon footprint thereby mitigating their environmental impact. Using an in-depth instrumental case study research design, this study has examined the use of renewable green energy systems by Delhi’s Indira Gandhi Airport and Mumbai’s Chhatrapati Shivaji Maharaj International Airport. The case study revealed that Chhatrapati Shivaji Maharaj International Airport has entirely switched to green sources for its energy consumption needs, thereby making it one of India’s 100 per cent sustainable airports. In April 2022, Mumbai Airport enhanced its usage of green energy when it deployed a 10Kwp Hybrid SolarMill consisting of 2Kwp TurboMill (three Savonious vertical axis type wind turbine (VAWT) and 8Kwp Solar PV modules. The new system has enabled Chhatrapati Shivaji Maharaj International Airport to reduce its carbon footprint as the new system will reduce its carbon dioxide (CO2) emissions by 120,000 tonnes per year. In 2022, Delhi’s Indira Gandhi Airport became the first airport in India to be powered entirely by hydro and solar energy sources. This energy-related measure is one of the airport’s key actions to realize its 2030 objective of being a Net Zero Carbon Emission Airport. By moving to renewable sources for its energy requirements, the airport is expected to reduce its carbon footprint by around 200,000 tons of carbon dioxide (CO2) emissions per annum. The use of green energy sources has helped the airports to mitigate the harmful environmental impact from the use of fossil-based fuels.

“…This approach is different from the conventional one where the power plants are located far from the loads and where there are many power losses in the transmission line (Copper losses, Magnetic Losses, Corona effect, and skin effect) [15]. In addition, 30% of the cost for delivering electricity is due to the transmission system [16]. Distributed renewable energy MPP are usually installed in combination with energy storage technologies (ESTs) such as Li-ion batteries, lead-acid, pumped hydro storage and supercapacitor energy storage [17].…”
