Cheapest long-duration storage for systems with high renewables
National Renewable Energy Laboratory researchers have studied which tech offers the lowest levelized cost of energy to provide the US Western Interconnection grid with electricity when wind and solar are not available. They assumed 85% renewables penetration and determined that geologic hydrogen storage and natural gas combined-cycle plants with carbon capture storage are the cheapest options for 120-hour discharge applications.
Compressed air tech for solar module cleaning, cooling shows promise in India field-testing
British scientists have reported significant restoration of the panel performance with the experimental compressed air system developed by them for the simultaneous cleaning and cooling of PV modules. The system was built with a compressed-air unit which was made of a compressor, an air tank, and an airflow regulation valve, and a series of nozzles. The technique was tested on a PV system located in northwestern India.
Madhya Pradesh tenders 500 MW grid-scale energy storage
State-owned Madhya Pradesh Power Management Company Limited (MPPMCL) has invited domestic and global players for providing grid-scale energy storage services of up to 500 MW with 8 hours of daily discharge and setting up a storage manufacturing facility in the state. The deadline for proposal submission is August 2.
