Solar-Powered Air Compressor: An Economical and Ecological Power Source for Remote Locations

Abstract

ABSTRACT Many, wellheads that require safety systems are located in remote areas where conventional power sources are not available. These safety systems require power in the form of hydraulic or pneumatic pressure to operate various sensors and wellhead equipment. Until now, remote locations have been limited to three sources of power: (1) bottled nitrogen, (2) Diesel/gasoline-powered systems, and (3) the use of gas off the well. Now, however, there is another option. A state-of-the-art, solar-powered air compressor has been developed that has the capability to provide the required power for the safety systems located in remote locations. In addition to offering an economical and ecological solution to the need for a safe and reliable power source, the solar-powered air compressor can provide a more cost-efficient option to the above alternatives. The solar-powered air compressor is inexpensive to maintain since primary service (battery replacement) is only necessary every 2 to 5 years, and the units can be transported easily as they are designed on 4-foot [1.22 meter] skids that fit into a standard pick-up truck. This paper will describe the operating principles and design considerations which led to the development of a new solar-powered system, four of which are currently in use in Gabon.
