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. 

About Energy Estate

Energy Estate’s mission is to accelerate the transformation of the energy sector and decarbonisation of industry. Since its formation in 2018, it has built a reputation for innovation and delivery, including co-developing over 30GW of large-scale decarbonisation projects, across onshore and offshore wind, solar, long duration energy storage, hydrogen production and electricity and hydrogen infrastructure.

The project involves construction of a new 662m, 20 span bridge over the Macquarie River, construction of 2.2km of new (Newell) highway and intersection upgrades between the Thompson Street/Whylandra Street intersection and the River Street/Bourke Street intersection in Dubbo, NSW, including intersections and adjoining roads.

Abergeldie CEO, Mark Bruzzone said “We are delighted to be selected to deliver this highly complex project to provide a safer, more reliable journey for road users and the local community. The construction crew is highly experienced and has been onsite since June delivering the new Dubbo Bridge early works which have provided great opportunities for local labour and contractors. We look forward to staring construction soon.

The project is a joint initiative funded by the Australian Government and NSW Government and is expected to be complete in 2026.

Chalmers Street Substation Power Supply Upgrade – Category 3 Winner

The Chalmers Street Substation, delivered for Transport for NSW (TfNSW), forms part of the Power Supply Upgrade Program, which provides the robust and reliable power needed to facilitate future rail network expansion, including support for a fleet of air-conditioned metro trains.

Scope of Works

The project was constructed and commissioned close to the existing live operating rail system, in a densely developed part of inner Sydney and had to be fully integrated with new system interfaces to existing electrical, telecommunications and civil infrastructure and installations. 

Delivery Approach

Management of the project required close communication and engagement with the community and key stakeholders. The project had a dedicated Environment, Community and Stakeholder Liaison Officer to effectively manage stakeholder engagement and liaison.

Sharing the site with Sydney Trains and working essentially along their access road for emergency maintenance vehicles meant that all work plans needed to incorporate a 15-minute Return-to-Services Action Plan.

TfNSW commended Abergeldie on their collaborative approach with the TfNSW project team, key stakeholders and interfacing projects to deliver Chalmers Street Substation. The success of the project was credited to Abergeldie’s positive engagement with TfNSW.

Lansdowne Bridge Replacement – Category 4 Winner

Lansdowne Bridge Replacemen was delivered for Transport for NSW (TfNSW) around 2km outside of Goulburn. The pre-existing bridge was at the end of its life span and access had been closed in 2017 due to dilapidation. Abergeldie constructed a new, two-lane, five-span concrete bridge with shared pedestrian/ cyclist facilities, along with road approaches, associated embankments and retaining walls.

Delivery Approach

Stakeholder management was key to a successful delivery of the project. Communication with TfNSW was open and frequent, and sharing a site office fostered a close collaborative environment where project challenges and setbacks were dealt with conjointly. Abergeldie also worked closely with Goulburn Mulwaree Council as they were performing roadworks in close proximity to the site as well as maintained close communication with adjacent landowners to facilitate land use for stockpiling, moving one land owners heritage stone wall due to a boundary adjustment and to ensure continued property access for reisdents affected by the works.

Abergeldie coordinated works and arranged alternate access to the site to facilitate the continuation of Council’s roadworks and further enhanced the relationship building assisting council to fix road damage occurring due to rain events.
