Future Hopper Energy Storage Systems utilizing Density Waves™ co-generating with a renewable system will provide utility scale electricity to the grid, especially at peak demand when a sustained loss of sunlight can be the most disruptive. Solar power has always needed a utility scale energy storage proponent because of the obvious disadvantage of night time electrical demand. During periods of low demand but high power production, solar farms would provide energy to re-compress the CO2 for storage and its later use in Hopper Plants.
A Hopper Energy Storage System used in combination with a renewable energy producer could allow operation much like a traditional on demand generation facility. These added capabilities could level the economic playing field for the renewable investor and provide incentive for the growth of these clean, safe and in demand methods of electricity generation. Until renewables can satisfactory demonstrate their reliability the necessary investments in grid infrastructure to accommodate them has not been present.
