US startup unveils saltwater flow battery for large-scale storage
US-based Salgenx has developed a scalable redox flow battery with two separate tanks of electrolytes, one of which is saltwater. Unlike other flow batteries, the new device is membrane-free, promising big gains at the levelized cost of storage level.
Key takeaways from Abu Dhabi’s World Future Energy Summit
The World Future Energy Summit showed that Middle Eastern solar markets are still driven by utility-scale PV, although the C&I sector shows signs of growth. Saudi Arabia, Egypt and the United Arab Emirates are the most promising markets for big solar projects, with huge pipelines under development, while Lebanon and Yemen show promise due to chronic energy shortages.
South Africa’s pipeline of unsubsidized PV projects hits 9 GW
The South African government has provided figures on “embedded generation projects” that are currently under development in the country. It also revealed that it will soon launch a tender for big storage projects.
New York grid operator advances 3 GW of solar, storage projects
About 27 GW of solar and storage projects remain in New York’s interconnection queue. The grid operator has also advanced 3 GW of wind projects and a 1.25 GW transmission line.
Weekend Read: Giga and giga
pv magazine Australia’s Natalie Filatoff reports on the benefits of planning vast solar project pipelines, and the barriers faced by those who dare to dream big.
Storing hydrogen in cryogenic tanks
Pusan National University researchers have found that hydrogen vaporization increases significantly as cryogenic tanks become emptier. The research sheds light on a key technology to transport hydrogen.
India’s Delectrik Systems starts commercial production of containerized redox flow battery systems
Delectrik Systems says multiple units of its 200 kWh battery system can be connected to build MWh-scale energy storage systems for use in on-grid and off-grid applications.
Survey: How should smart grids be implemented?
PV integration in smart grids is a complex but highly relevant issue, with various aspects to be considered to develop different scenarios. Researchers in the IEA-PVPS Task 14 program are conducting a survey to collect opinions from peers in the PV branch to perform such an analysis.
The case for flywheel storage in the Philippines
An international research team is assessing the potential of flywheels for renewables storage in the Philippines. They considered the use of a flywheel energy storage system developed by US-based Amber Kinetics.
