Pumped Storage and Carbon Footprint—Pumped Storage Reduces Emissions In an environment where pumped storage is employed as an alternative to on-peak carbon based production, pumped storage reduces CO2 output. Here is an example calculation that applies to the 1,120 MW Hook Canyon project. The contrast is with natural gas, since it is the most likely alternative for additional on-peak generation in Utah. By eliminating the need to add 1,120 MW of natural gas capacity, Hook Canyon would prevent 2.2 million tons of carbon dioxide, 2000 tons of nitrous oxide and 24 tons of sulfur dioxide from being released into the atmosphere. Carbon dioxide and sulfur dioxide are the primary factors contributing to heightened levels of smog and hence red air days in Utah.
