Abstract:

For over 150 years, windmills have captured wind energy to provide water for stock and human needs in remote locations. However, to manage the unpredictable energy source and ensure daily water supply, a large stock tank is required which leads to increased evaporation. Continuous winds can cause tank overflow and additional wastage. With increasing concern for diminishing water resources, this is no longer acceptable. This study will determine the feasibility of developing a wind-powered water pumping system that incorporates Compressed Air Energy Storage (CAES). The proposed system will use a wind turbine to directly drive an air compressor supplying an air storage tank at the well site. The compressor and air tank will be connected using low-cost air line, allowing the compressor tower to be placed at the optimum wind location, such as a nearby hill. A proprietary method will be investigated to maximize the energy storage in a small footprint, while also allowing compressor heat to be used to help prevent the stock water from freezing in cold conditions. The stored air will power a compressed air submersible water pump (already commercially available). CAES will provide energy storage to allow water pumping on-demand during times of no wind. Unlike batteries, CAES is tolerant of freezing conditions, will not require regular maintenance or replacement, and does not employ toxic materials. Additional advantages will also be investigated. For example, excess air could aerate the water tank to reduce bio-fouling, stagnation and mosquito larvae.
