Technical FAQs 4

Could a water-based 'flow battery' transform home solar energy?

Researchers in Australia have created a new kind of water-based “flow battery” that could transform how households store rooftop solar energy. Credit: Stock Monash scientists designed a fast, safe liquid battery for home solar. The system could outperform expensive lithium-ion options.

What is a flow battery?

Their next-generation “flow battery” opens the door to compact, high-performance battery systems for homes, and is expected to be much cheaper than current $10,000 lithium-ion systems. Flow batteries have been around for decades but have traditionally been used in large-scale energy storage due to their large size and slow charge speeds.

Why are flow batteries limited to large-scale energy storage?

Although flow batteries have existed for decades, they have mostly been limited to large-scale energy storage because of their bulk and relatively slow charging times.

Could a water-based battery outperform a lithium-ion Solar System?

Follow us on Google, Discover, and News. Monash scientists designed a fast, safe liquid battery for home solar. The system could outperform expensive lithium-ion options. Engineers have created a new water-based battery designed to make rooftop solar storage in Australian homes safer, more affordable, and more efficient.
