Dish Stirling System Potential Assessment for Eight Main Sites in Madagascar

Abstract

Solar energy is a green and attractive renewable energy source that can be converted for power generation. The objective of this work is to evaluate the potential of dish Stirling systems if they are used in the fourth worldwide largest island of Madagascar. For that purpose, a theoretical model of the dish Stirling system based on the geometrical configuration and heat transfer was developed and coded on Matlab. Simulations were run to investigate the energy efficiency variation of the system for eight main sites in Madagascar. As results, the proposed model enables to represent the system thermal behaviour to assess its efficiency. Among the eight studied sites, those which are on the coastal zones are more propitious to the dish Stirling system. While, in the north and northwest, the sites of Diego Suarez and Majunga present high efficiencies with, respectively, 31.65(%) and 31.07(%), it is in the south in fort-dauphin that thermal efficiency rate is maximal with 32.17(%). Convincing results that suggest that the implementation of this kind of facility will solve a large part of energy supply problems in these regions.Jean Philippe Praene et al.

Study on carbon dioxide atmospheric distribution over the Southwest Indian Ocean islands using satellite data: Part 1 – Climatology and seasonal results

“…Reunion and Mauritius islands are net sources of CO 2 and their emissions are dominated by the energy sector. Madagascar and Comoros islands are net sinks of CO 2 and its emissions are dominated by land use and land change sector (MEF, 2010;MESD, 2010;Praene et al, 2011;Praene et al, 2016). (Fig.…”

“…Although tropical forest deforestation and degradation is an important source of atmospheric CO 2 over the SWIO islands, there are other contributing emitters of this GHG, each with varied relative strength in each island (Ministry of Development, Infrastructure, Post and Telecommunications and International Transports (MDIPTIT), 2002; Ministry of Environments and Forests (MEF), 2010; Ministry of Environment and Sustainable Development (MESD), 2010; Climalia, 2015;Praene et al, 2016). In 2000, Madagascar emissions represented 0.2% of total global emissions, and the country was a net carbon sink with a capacity of 13 Mt CO 2 per capita.…”

“…It is projected that by 2030, this country may be turned into a CO 2 source if emissions increase and the forest absorption capacity is not increased (Climalia, 2015). The land use and land change source sector is an important source of CO 2 emissions in Madagascar (MEF, 2010;Praene et al, 2016). Both the 1994 and 2000 Comoros emissions inventory reports indicated that the country was a net sink with a capacity of 0.71 tons and 5.05 tons per capita, respectively.…”

“…These hotspots coincided with the location of gemstone and gold artisanal mining activities reported by Cook and Healy (2012). These anthropogenic activities involve deforestation and forest degradation, a major source of CO 2 over the SWIO islands (MDIPTIT, 2002;MEF, 2010;MESD, 2010;World Bank, 2015;Praene et al, 2016). These hotspots were easily visible during the summer and autumn season as the background CO 2 concentrations were relatively low ( Fig.…”

Impacts Generated by a Large-Scale Solar Photovoltaic Power Plant Can Lead to Conflicts between Sustainable Development Goals: A Review of Key Lessons Learned in Madagascar

“…Regarding solar PV potential [82], of the 692 MW of installed capacity, around 33 MW comes from photovoltaic solar energy [83], which gradually came up since 2006; by 2018, 1% of the energy mix came from renewable energies [79]. This installed capacity should increase rapidly since the current trend of international donors is to develop the exploitation of renewable resources.…”
