Energy Estate and Abergeldie Complex Infrastructure collaborate on hydrogen production and storage to accelerate the energy transition in Australia

Energy Estate and Abergeldie Complex Infrastructure have signed a Memorandum of Understanding to collaborate on opportunities for 24/7 delivery of green hydrogen, e-fuels and e-chemicals across Energy Estate’s extensive portfolio of over 30GW of large-scale decarbonisation projects.  

Integrating green hydrogen production and storage will help balance intermittent renewable energy supplies and enable the delivery on a 24/7 basis to ammonia, e-fuel and other hydrogen derivative production facilities. As part of the collaboration the parties will work together to encourage new investment into the green hydrogen sector in NSW and other States in Australia.

The first integrated green hydrogen and storage project to be advanced is the Hunter Hydrogen Network developed by Energy Estate and its partner Eurus Energy. This is a proposed 1.6GW hydrogen production project in the Hunter Valley coupled with to be delivered via a shared, dedicated hydrogen pipeline to the Port of Newcastle and other strategic locations in the Hunter.

“Strategically optimised hydrogen production and storage is the next level of sophistication for the delivery of lowest cost hydrogen. Our vision is to create hydrogen corridors to produce, store and deliver hydrogen in the most cost effective and efficient way to foster local and export markets for green hydrogen and derivative products.” said Simon Currie, Co-Founder of Energy Estate. 

“We are delighted to deepen our collaboration with an Australian owned business with a storage technology critical to the advancement of the hydrogen economy. This collaboration that will be important in informing the continued development of our portfolio of hydrogen projects” said Simone O’Sullivan, director of decarbonisation at Energy Estate.

“Abergeldie Complex Infrastructure is looking forward to collaborating with Energy Estate on green hydrogen projects. Abergeldie established Ardent Underground in 2019 to repurpose our world leading blind boring technology so as develop safe, cost-effective, large scale and replicable hydrogen storage” said Mick Boyle Abergeldie Founder and Executive Chairman

David Bentley, General Manager, Ardent Underground said “We have developed a unique hydrogen storage technology and are fully supported by Abergeldie’s proven track record of delivering complex infrastructure. Locally, we are already seeing significant opportunities for the optimisation of large-scale renewal hydrogen production and storage projects. Ardent Underground is looking forward to working with the Energy Estate and Abergeldie collaboration to accelerate the transition to green hydrogen”.

About H2N

Energy Estate and Eurus Energy are developing the Hunter Hydrogen Network (H2N), backbone infrastructure and core projects drawing on the existing industrial ecosystem of the Hunter and delivering competitively priced hydrogen and derivative products through and from the Hunter Valley.  It will be Australia’s first “hydrogen valley” and will involve large-scale electrolysers in the Upper Hunter and a 120km dedicated hydrogen pipeline through the Hunter Valley.  It will be supported by large-scale renewable energy generation from the Renewable Energy Zones in NSW and will enable downstream production facilities for various derivative productions (e.g. Ammonia, e-fuels, methanol, liquid hydrogen etc), located in the lower Hunter Valley.

Having completed an initial scoping study for H2N, Energy Estate, with its collaboration partners, is continuing its development activity and preparing to undertake a feasibility study for the delivery of competitively priced hydrogen and derivative products in the Hunter.
