GreenHy2 (ASX:H2G) powers green getaway

In an Australian first GreenHy2 (ASX:H2G) partner Essential Energy is trialling a hydrogen‐powered Stand Alone Power System (SAPS) to power a heritage accommodation cottage located on the banks of the Myall Lakes National Park on the mid‐north coast of NSW.

Essential Energy is partnering with NSW National Parks and Wildlife Services (NPWS) to determine the best range of high‐tech renewable solutions that could power other sensitive environments in our network footprint.

The trial is part of Essential Energy’s broader push to provide a viable renewable energy solution, supporting the move toward a sustainable, low‐carbon future and helping to drive down overall energy prices for all its customers.

“The technology, first developed in Germany, consists of 23kW solar panels, a battery, hydrogen electrolysers and fuel cells and hydrogen storage of up to 20 days (425-kilowatt hours),” Essential Energy’s COO Luke Jenner said.

He said GreenHy2 (ASX code H2G; formerly Tempo Australia) were chosen to supply this unit due to its solution, removing the need for backup generators.

“Since commissioning, and after an initial period of optimising the flows of energy between storage and customer, the system’s performance has met expectations and is delivering reliable power to the Cottage,” he said.

“The green hydrogen SAPS at Cutlers Cottage uses solar power to convert water to hydrogen, which is stored in a solid state as a metal hydride within a stand‐alone modular unit, delivering uninterrupted power to the cottage.

“As well as powering the cottage with zero emissions, the unit improves natural disaster resilience for the Cottage as it isn’t reliant on the surrounding energy infrastructure.

Significant savings from reducing usual costs associated with managing power poles and powerlines to the Cottage, including vegetation management, will ultimately benefit all our customers.”

NSW Department of Planning and Environment NPWS, Atticus Fleming, said The Cutlers Cottage accommodation was chosen for satisfying a range of criteria following engagement with NPWS.

“We’re really interested to see the results of this trial and how effective hydrogen will be in removing the nearly 6km of line that travels through dense bushland and over land that is subject to flooding, which will be a huge win‐win,” Mr Fleming, the Acting Coordinator‐ General, Environment and Heritage, said.

“It means better reliability for our guests and reduced bushfire risk.”

“This site allows us to enhance an important working relationship with NPWS. The site has good access, and we already had its load profile at a granular level following the previous consultation with NPWS and a neighbouring private site (already utilising an Essential Energy SAPS). Hence, it makes a good candidate to measure what the system can deliver in Essential Energy’s solution offerings,” Mr Jenner supported.

He added that while a heritage cottage is a relatively unusual site for an energy trial, it will deepen Essential Energy’s understanding and capability as the technology on this relatively new but high-potential energy source develops.

“This trial will equip us with a range of knowledge, including a better understanding of best use cases for Hydrogen SAPS, as well as other factors such as site preparation, expected reliability levels, and opportunities to improve our internal skills,” Mr Jenner said.
