$1.25m awarded to Stanwell for hydrogen plant feasibility study

Queensland’s largest electricity generator Stanwell Corporation has been awarded £1.25m in ARENA funding to assess the feasibility of a renewable hydrogen demonstration plant.

Stanwell is aiming to encourage the growth of a hydrogen export industry in Central Queensland which would drive energy load growth in the region, ease pressure on the electricity network and support the growth of renewable energy.

The company’s $5m feasibility study commenced in July last year and is investigating the technical and economic feasibility of the installation of 10MW or greater of hydrogen electrolysis at the Stanwell Power Station site south-west of Rockhampton.

If built, this would be the largest hydrogen electrolysis plant in Australia.

Along with determining the optimal design, a key outcome of the study will be to define the highest value end use for the renewable hydrogen produced.

Stanwell Power Station offers a unique proposition in demonstrating the role that renewable hydrogen production can play to benefit the electricity system.

The hydrogen electrolyser could be used as a complimentary energy market load that can ramp up in times of excess energy supply, such as peak solar output during the day.

The electrolyser could also aid system security through participation in Frequency Control Ancillary Services (FCAS) markets or future markets such as Fast Frequency Response (FFR).

By using an existing power station, there are also benefits in being able to use pre-existing land approval, network connection and access to demineralised water which is required for hydrogen production.

With the hydrogen industry in its infancy in Australia, the study would determine the optimal conditions for electrolysers operating at high capacities.

Stanwell will procure energy and green certificates from renewable energy projects in the region to offset 100% of the emissions associated with running the electrolyser.

ARENA CEO Darren Miller said the project continues ARENA’s commitment to driving innovation in the hydrogen supply chain.

“Through Stanwell’s feasibility study we’re showing a new option for producing and using renewable hydrogen,” Miller said.

“This will create opportunities across the domestic economy and help to position Australia to become a major renewable energy exporter.”

“The construction and operation of a utility scale electrolyser is important to demonstrate the costs associated with producing renewable hydrogen at scale.”

“If feasible, this could help underpin future commercial scale deployments leveraging existing network infrastructure at other power stations, and play a role in driving down the cost of domestic hydrogen production.”

Stanwell’s feasibility study is expected to be completed in late 2020.
