Now a very refreshing change from the Greeny type bulldust leaking out of DDH. SA backs 2nd renewables-to-gas hydrogen plant, in TonsleyBy Sophie Vorrath on 21 February 2018
SA is set to host its 2nd hydrogen production and distribution facility, with the construction of a 1.25MW Siemens electrolyser that will produce hydrogen using electricity from the grid and potentially on-site solar.The $11.4 mill project, announced on Wednesday by the Australian Gas Infrastructure Group (AGIG), will be built at the Tonsely Innovation Disctrict in Adelaide – the industrial suburb built around the former Mitsubishi car manufacturing plant.
It is not the only example of power to gas technology being developed in Australia, or in SA, for that matter.
Earlier this month, the SA govt announced funding for a 15MW renewable-H2 electrolyser plant to be built near the end of the grid at Port Lincoln on the Eyre Peninsula,
The Port Lincoln facility – to be built by Hydrogen Utility (H2U), working with Germany’s thyssenkrupp – will include a 10MW H2-fired gas turbine, fuelled by local wind and solar power, and a 5MW H2 fuel cell. It remains to be seen which SA project will be completed first.
And in the ACT back in 2016, Neoen and Megawatt Capital announced plans invest $55 mill in partnership with Siemens and Hyundai to establish a 1.25MW H2 electrolyser, including a H2 refuelling station and service centre and an initial fleet of 20 H2 fuelled cars, including a technical support and research program.
The news of the SA Tonsley project coincides with a separate announcement from Carnegie Clean Energy, of its own plans to transform the former Adelaide General Motors Holden factory into a solar and battery storage microgrid, with backing from the SA govt.
And of course the SA govt had a fairly major announcement of its own on Wednesday, revealing pre-election policy plans to boost its renewable energy target to 75% by 2025, and to introduce the nation’s first “energy storage target” of 750MW by the same date.
The hydrogen produced by the Tonsley-based power-to-gas demonstration plant – to be known as Hydrogen Park SA (HyP SA) – will be injected into AGIG’s local gas network. intially to power the Tonsley Innovation District – but with the ability to supply a proposed residential development in the area and other remote customers through tube and trailer facilities.
As one of the 1st major demonstration of the technology, the facility is also expected to play a crucial role in showing how electrolysers can be integrated into electricity networks around the country, to support energy stability as more renewable energy generation capacity comes onto the grid.
Like the newly announced microgrid at the former Holden plant, the Hydrogen Park project has been awarded grant funding from the SA govt – in this case, $4.9 mill from the $150 mill Renewable Technology Fund.
“We are delighted that SA will lead the way with this pioneering technology,” AGIG’s Andrew Staniford said on Wednesday.
“The project is expected to be the 1st in Australia where renewable electricity is stored and distributed in the gas network as H2, providing an additional market for fluctuating renewable electricity and thereby also improving the economics of renewable electricity.
“And importantly, it propels SA’s status as a leader in renewable technology and a first mover in hydrogen,” Staniford said.
Jeff Connolly, CEO and chair of Siemens Aust said his company was excited to be a part of delivering “proven and world leading H2 technology” to Australia.
“It’s pleasing to see H2 become reality since we began driving this conversation in Australia only a few short years ago,” he said from the CEDA: Economic and Political Overview in Adelaide event in Adelaide on Wednesday.
“Reticulating H2 into the gas network supports de-carbonisation of the state.
“It also supports the development of a domestic market for H2 which I believe can lead to Australia becoming a renewable energy export superpower if we harness the untapped renewable assets of the country.”
Siemens’ electrolyser technology will use proton exchange membrane (PEM), which are designed to operate in highly variable conditions such as those created by renewable energy generation.
According to Siemens, PEM Electrolysers have a very fast start-up time and can quickly absorb excess renewable energy from a power system, converting water into hydrogen and oxygen.
“These utility scale electrolysers can, with surgical precision, be energized and de-energized in less than 10 secs, capturing excess energy from the grid when energised,” Siemens said.
Essentially, it added, they play a demand side management role within the energy system, and may be used as a tool to keep the grid in balance.
“This is about using inexpensive or free energy, which would otherwise be spilled to produce a clean form of stored energy that has many value streams – 100% pure H2, with the only by-product being 100% pure oxygen.”
