Flywheel storage pilot in Philippines

Flywheel storage pilot in Philippines

Amber Kinetics, a US developer of a multi-hour flywheel energy storage
system, is piloting its technology in the Philippines and Hawaii.

In the Philippines, Amber Kinetics is working with local independent power
producer Emerging Power, a subsidiary of mining firm Nickel Asia
Corporation. A single flywheel with a capacity of 6.25/25kWh was installed
earlier this month.

The pilot project will be used to integrate generation from a 150MW wind and
solar photovoltaic (PV) project Emerging Power built earlier this year near
Subic Bay, in the north-west of the country.

Amber Kinetics also has a memorandum of understanding (MoU) with Emerging
Power for a 10MW/40MWh flywheel energy storage system, should the pilot
prove successful, which will smooth the variability of solar and wind into
the transmission system.

Flywheel energy storage works by rotating steel rotors at extremely high
speeds, to store kinetic energy, which can be discharged when required.

Flywheels can be cycled - the charging up and releasing of energy - many
thousands of times, with little degradation, unlike cells in lithium
batteries, which degrade after a few thousand cycles.

"Maintenance consists of changing bearings, about every ten years, which are
easily accessible to swap out," said Amber Kinetics vice president of
project development, Mark Stout.
