Water from the sun : Case study: The Abu Dhabi solar desalination plant

The Abu Dhabi solar desalination plant is situated at the Umm Al Nar Power and Desalination Station about 20 miles east of Abu Dhabi city. The design, procurement and fabrication of this plant started in February 1983 and it was commissioned in September 1984. The plant was designed as a demonstration unit aimed at evaluating the technical and economic feasibility of using this type of technology to provide remote coastal communities in the UAE with fresh water. Ali M. El-Nashar, Manager, Abu Dhabi Water & Electricity Authority provides an overview of the plant performance and presents an economic assessment of the cost of water from such a plant highlighting how solar energy has been helping to provide water to the region for over 15 years.

Feasibility of renewable energy storage using hydrogen in remote communities in Bhutan

This paper considers the technical and economic feasibility of using renewable energy with hydrogen as the energy storage medium for two remote communities in Bhutan, selected to illustrate two common scenarios presenting different challenges. The Royal Government of Bhutan has published plans to provide electricity to all households in the next 20 years, but the practical problems of extending the grid over long distances and mountainous terrain will make that target difficult and expensive to achieve. Consequently, the possibility of using natural energy and diversified generation is attractive. This paper examines the use of hydro power in one community and photovoltaics with wind power in another. Hydrogen is the proposed energy storage medium in both cases. Analysis suggests that it is technically possible to use renewable energy and hydrogen for diversified power supplies and that where, as here, the costs of grid extension are high, it may also be financially viable. Thus we argue that there is a good case for establishing a test and demonstration system near the capital Thimphu for further investigation prior to use in remote locations.

From research and development to the market: Photovoltaics in France

The development of photovoltaics in France must occur in an environment in which photovoltaic (PV) energy is in direct competition with centralised production sources. The strategy adopted by the AFME is to make the best use of photovoltaics. A PV generator can produce electricity, where it is needed, for various applications such as the electrification of remote sites with power consumption ranging from a few watts to a few tens of kilowatts. The PV industry in France offers technically interesting and innovative possibilities with crystalline and amorphous silicon materials. AFME's programme for 1988 – 1992, including research and development and demonstration programmes, has recently been implemented with public funds of 3 M $/year.     

Promoting photovoltaic electricity usage in developing countries — Experience from Ghana

The awareness of PV systems as a means to provide electricity for remote small towns and villages with small electrical loads has long been recognised. That PV electricity is not widely patronised by the potential end-users can be attributed to lack of awareness of the existence of the technology and the high initial cost of systems which necessarily has to be paid up front. It is argued that demonstration PV systems can be used to awaken awareness. This will open up the dormant large PV market waiting to be tapped in the developing countries, and this will be the benefit of the PV manufacturers who can take advantage of the economies of scale to reduce PV systems production cost and, therefore, a reduced selling price. Suggestions are also made for financing the purchase of PV systems by end-users in the developing countries.
