Endua unveils prototype power bank system

Endua, an energy storage company that last month announced $11.8 million in pre-series private funding ($7.5 million for private sources), has unveiled the first of its modular hydrogen power banks.

According to a statement on Tuesday, the new system will be used for testing as Endua develops its green hydrogen solution with a focus on microgrid and standalone power markets. It will be located in Archerfield, Brisbane, the suburb Endua is based in.

The company, which was established in 2021, aims to offer power banks measuring approximately six metres long and three metres wide, and able to drive up power loads of up to 100 kilowatts each.

“To store and use hydrogen like a battery, you need to convert water and renewable energy to hydrogen with an electrolyser, store hydrogen until it’s needed and then convert it back to electricity using a fuel cell,” said CEO and founder Paul Sernia. 

“Our power banks plug a critical gap in achieving the clean energy transition and stabilising power when the grid can not be relied on — especially in our regional and remote power communities — generating enough stored hydrogen to replace diesel for off-grid power generation at any site such as a cattle farm or power communications equipment operating at the edge.”

Sernia said that $1.5 billion is spent annually on diesel fuel for electricity in remote and rural areas – with heavy greenhouse gas emissions and operational costs – through battery storage as an alternative only offers a few hours of energy.

Endua was established with $5 million in backing from Main Sequence and Ampol, and uses electrolyser technology developed at CSIRO as part of its system.
