February 21, 2019: A microgrid project will combine lithium ion and zinc bromide flow batteries coupled with solar at a remote Thai village, flow battery maker Redflow announced on February 13.
The Thai government backed project in the village of Ban Pha Dan in Lamphun province, combines 10 Redflow ZBM2 10kWh batteries, three 100kWh lithium batteries from Chinese firm KStar and solar cells.
TSUS (Tusas Excellent Engineering Company) installed the flow batteries that will supply power to the community’s school, town hall and temple while the lithium batteries will deliver power to individual houses. Villagers can also use the power for their water systems for drinking and agriculture.
A Redflow spokesman told ESJ the initial configuration might change as the deployment evolves.
He said: “Redflow batteries are designed to support high cycle-rate, long time-base stationary energy storage applications — in a nutshell, they thrive on heat and hard work.
“The school, town hall and temple are three of the village’s larger buildings, so the system designers focussed the Redflow batteries on supplying their energy needs.”
While primarily meeting the energy needs of Ban Pha Dan, this hybrid ESS is intended to provide experience and insights for future projects.
The project is the first commercial installation of Redflow batteries in Thailand since it began manufacturing batteries in its Bangkok facility last June.
