Digital Edge Develops HSC Energy Storage System to Replace Traditional Batteries

APAC data centre operator Digital Edge has developed a new energy storage system to replace traditional batteries at its data centres. Digital Edge has partnered with South Korean power solutions company Donghwa ES to create what it calls a Hybrid Super Capacitor (HSC) Energy Storage System, a new type of alternative power supply for its UPS systems. Digital Edge claims this alternative has the potential to revolutionise data centre ancillary power generation for future AI and hyperscale workloads.

Traditional Batteries

According to the company, the data centre industry currently relies on lithium-ion batteries or lead-acid batteries for backup generators and Uninterruptible Power Supplies (UPS), which enable operators to maintain uptime in the event of a grid power failure. However, as the demand for higher power density deployments increases, the data centre industry faces growing pressure to improve energy efficiency and reduce its carbon footprint.

HSC Energy Storage System

The two companies have jointly developed the HSC Energy Storage System technology. Digital Edge says initial testing has been successful, and the company has confirmed plans to deploy this technology in certain new-build data centres.

The HSC technology uses a hybrid energy storage method that combines activated carbon from an electric double-layer capacitor with carbon from a lithium-ion battery. This combination produces a solution that reduces the deterioration of the negative electrode compared to other technologies.

Extended Lifespan

This enables the HSC to operate for a longer lifespan, with an estimated replacement cycle of more than 15 years, or nearly 2.5 times longer than other battery products, the data centre company explained.
