Steam Augmentation
Coal-Fired Power Generation: Ausra's innovative solar steam generators can be deployed at existing coal-fired power stations to deliver direct solar steam. Customers can increase plant output while lowering emissions. Ausra's solar system can replace the extraction steam used for feedwater heating in a coal station with solar steam from a reliable, land-efficient solar field. The steam that is not extracted can continue expanding through the steam turbine and produce more electricity without increasing plant emissions.
Combined-Cycle Power Generation: Ausra's innovative solar steam generators are designed to deliver reliable, direct solar steam to our customers' existing natural gas-fired power stations to increase plant output, lower emissions and hedge against volatile fuel prices. The deployment of Ausra's solar steam generators at an existing gas-fired, combined-cycle facility enable the mixing of steam from Ausra's solar field with a power plant's intermediate pressure (IP) evaporator or cold reheat steam. The introduction of solar steam enables the steam turbine to produce additional electricity without additional fuel.
Opportunity- Co-locate solar steam generators with existing or new build fossil-fueled power plants
- Repower/extend plant life for geothermal and biomass facilities
Advantages
- Increase output of existing capital equipment
- Match peak electricity demand
- Reduce fuel consumption
- Reduce carbon and other emissions
- Rapid deployment (< 1yr to COD)
