Green power storage with pump turbine
scalable modular pump turbine for electric power of 0.5 MW to 15 MW
- highly efficient storage system with system efficiency of 70-80%
- short switchover time between electricity storage and generation
- cost-effective, due to the use of serially manufactured standard components, as well as to the use of water in two reservoirs
- modular system of identical impeller and motor/generator units, in combination with commercially available frequency converters
- long service life with consistent quality; short production time
- for the regionally autonomous energy management to cover demand peaks
- well suited for combination with other storage technologies - provides a reliable basis for hybridization
Level of Innovation
- decentralized and autonomous power management at low and medium voltage level - protects against blackout; medium-term independence from the higher-level voltage or high-voltage system
- first fully modularized pump turbine manufactured in series for low-cost storage systems
Target Groups and Applications
- energy-intensive large-scale industrial facilities
- municipal or decentralized energy supply
- builders and operators of wind power or photovoltaic sites
- grid operators and transregional energy suppliers
- industry with highly fluctuating electric power demand or with the potential to supply electric power
- showcase regions, regional and urban planning
- utilization of existing water reservoirs and unused caverns or shut-down mines and pits
- flexibility enhancement of existing high-pressure hydropower plants through retrofitting
- highly efficient system offering large storage capacity for low-cost and rare-earth-metal-reduced hybrid storage solutions
