Hydrogen-based generators are an environmentally-friendly alternative to ones powered by diesel fuel. But many rely on solar, hydro or wind power, which aren’t available all the time. Brisbane-based Endua is making hydrogen-based power generators more accessible by using electrolysis to create more hydrogen and storing it for long-term use. The startup’s technology was developed at CSIRO, Australian’s national science agency, and is being commercialized by Main Sequence, the venture fund founded by CSIRO and Ampol, one of the country’s largest fuel companies.
Main Sequence’s venture science model means that it first identifies a global challenge, then brings together the technology, team and investors to launch a startup that can address that problem. Through the program, Paul Sernia, the founder of electric vehicle charger maker Tritium, was brought on to serve as Endua’s chief executive officer, working with Main Sequence partner Martin Duursma to commercialize the hydrogen-based power generation and storage technology developed at CSIRO. Ampol will serve as Endua’s industry partner.
Endua is backed by $5 million AUD (about $3.9 million USD) from Main Sequence, CSIRO and Ampol. The company plans to launch in Australia first before expanding into other countries.
Sernia told TC that Endua was created to “solve one of the biggest problems facing the transition to renewable energy—how to store renewable energy in large quantities, for long periods of time.”
Endua’s modular power banks can run up to 150 kilowatts per pack and be extended for different use cases, serving as an alternative to power generators that run on diesel fuel. Batteries serve as backup, but Endua’s goal is to deliver renewable energy that can be stored in large quantities, enabling off-grid infrastructure and communities to have self-sustaining power sources.
“Hydrogen electrolysis technology has been around for quite some time but it still has a long way to go to meet the expectations of commercial markets and be cost-effective when compared to existing energy sources,” Sernia said. “The technology we’ve developed with CSIRO enables us to make the cost more affordable compared to fossil fuel sources, more reliable and easily maintained in remote communities.”
The startup plans to focus on industrial clients before reaching smaller businesses and residences. “One of the biggest opportunities, that few have really tackled, is that of diesel generator users like regional communities, mines or remote infrastructure,” Sernia said. “In farming, Endua’s solution could be used to power equipment such as a bore or irrigation pumps.” The power banks can plug into existing renewable energy systems, including solar and wind, to make the switch economical for users, he added. Water is part of the electrolysis process, but only a small amount is needed.
“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,” Sernia told TC.
Ampol is working with Endua as part of its Future Energy and Decarbonisation Strategy. It will test and commercialize Endua’s tech to reach its 80,000 B2B customers, focusing first on the off-grid diesel generator market, which the company said generates 200,000 tonnes of carbon emissions per year.
In press statement, Ampol managing director and CEO Matthew Halliday said, “We are excited to be involved with Endua, which is part of our commitment to extending our customer value proposition by finding and developing new energy solutions that will assist with their energy transition.”
