Wind Turbine Tower for Storing Hydrogen and Energy

Around the world, there is an increasing demand for satisfying energy requirements in ways that use less or no fossil fuels. These alternatives need to be reliable, cost effective, and environmentally sound to be adopted on a large scale. For example, as the need to stabilize energy resources increases, many nations and electric utilities are evaluating the increased use of wind as a portion of their power generation mix. Additionally, the use of hydrogen as a “clean” fuel to replace fossil fuels is being seriously considered and investigated by many in the energy industry. While hydrogen may be generated in a number of ways, a growing trend is to convert water by electrolysis to produce hydrogen. In this regard, an electrolyzer uses an electric current to separate water into hydrogen and oxygen. When a wind turbine is used to produce the hydrogen, the hydrogen can be used to drive a fuel cell or combination device which can convert hydrogen into electricity.

Benefits: 
Enhanced dispatch ability by allowing the wind turbine to operate when wind is available and using the energy storage system to store energy when demand is lower and to provide additional energy when demand is higher
