Australian startup develops hydrogen-powered clean energy storage

Endua’s modular power banks serve as a model for a larger goal, which is to allow renewable energy to be stored in large quantities

Spotted: The Brisbane-based startup Endua is developing hydrogen-based, modular power generators with the goal of improving access to clean energy sources. The is done through electrolysis, which is able to produce more hydrogen that can be stored for long-term use.  

With technology developed at CSIRO, Australia’s national science agency, Endua’s modular power banks can supply up to 150 kilowatts per pack. This provides a  greener alternative to power generators that use only diesel fuel. Ultimately, Endua wants to increase the storage capacity to create reliable self-sustaining power sources.

“Batteries are a great way to deliver dispatchable power in small increments and are a complementary part of the overall transition plan, but we’re focusing on delivering renewable energy that can be stored in large quantities, for large periods of time, so communities and remote infrastructure can access reliable, renewable energy at any time of day,”  Paul Sernia, the founder of electric vehicle charger maker Tritium, told TechCrunch. 

For some time, one of the biggest hurdles in transitioning to renewable energy has been how to store renewable energy in large quantities, over extended periods of time. Endua was created with the aim to solve this, according to Sernia. Whilst Hydrogen-based generators are an environmentally friendly alternative to ones powered by diesel fuel, many rely on solar, hydro or wind power – which can be inconsistent.
