How can the GreenTower produce power during night hours? Can it produce peak power?
Due to its high heat capacity water, covered by plastic sheeting, will absorb much heat during the day in these thermal energy stores and release it to incoming cold air during the night. A 20 cm water layer will equalize power production over a 24 hour period. 1,2 m deep controllable water ponds store and release heat for 6 days. A very effective means has been developed to stop or magnify heat transfer from these quick-response thermal energy stores so that power generation can be increased from 10% to 100% within four minutes. Hence high-priced peak power can be delivered at any time. Additional seasonal storage can be supplied at very modest cost. By increasing the collector size to 37,5 km² (diameter = 6,9km) full power production throughout the 24 hour cycle is achieved. By switching off related irrigation schemes (pumping, desalination) during high demand periods their power can be fed into the grid as peak power. The more water is desalinated the more high-priced peak power can
