No Longer a Pipe Dream: Achieving Net-Zero Emissions with Hydrogen

Setting up a hub of hydrogen activity in South Australia’s Tonsley Innovation District
Hydrogen Park South Australia is Australia’s first milestone in its renewable gas journey, and will set the wheels in motion towards our ambition of achieving net-zero carbon emissions.

Power-to-Gas project in South Australia

Hydrogen has been dubbed the fuel of the future, an answer to the world’s escalating energy. And rightly so, with it being one of the most abundant element found in the universe, the ability to produce electricity without any harmful by-products, and the unlimited applications across industries.


South Australia is working towards net zero carbon emissions by 2050 and this vision foresees various low carbon project and initiatives. Australian Gas Network (AGN), part of the Australian Gas Infrastructure Group (AGIG), has taken the first step towards low carbon gas supply through an innovative project called Hydrogen Park South Australia (HyPSA).


Located within Tonsley Innovation District, HyPSA is an $11.4 million demonstration project with a $4.9 million grant from the South Australian Government.


Australia’s largest hydrogen electrolyser today

Siemens Energy is one of the industry partners of HyPSA by virtue of its 1.25 MW Sylizer proton exchange membrane (PEM) electrolyser, the largest of its kind installed in Australia today. With the electrolyser, renewable hydrogen is produced using water and renewable electricity. The highly dynamic PEM technology is ideally suited to harvest volatile energy generated from wind and solar power, which makes the process entirely renewable.


With this innovative solution, the facility is able to produce an estimated of 20-kilograms of clean hydrogen per hour and is projected to produce 175 tonnes of green hydrogen each year. The hydrogen that is produced can then be stored for later use or sent directly to the hydrogen and gas blending equipment or compressed into hydrogen tube trailers for transporting.


Up to 5% of renewable hydrogen is then blended with natural gas and, since May 2021, has been supplied to around 700 nearby homes via the existing gas network. Residents still receive the same quality of gas and service with the same price.

At Siemens Energy, we are on a quest to reshape the energy landscape of tomorrow. Our commitment to promoting and developing projects and technologies to produce green hydrogen has led us to developing and refining our Silyzer portfolio of solutions, and this will support both private and public sectors’ efforts in meeting the growing global demand for energy while transitioning to a more sustainable world.

Power-to-X: The crucial business on the way to a carbon-free world

Green e-Hydrogen gained via electrolysis from renewable energy sources is the key to a CO2-free future. Find all you need to know in the new Siemens white paper on Power-to-X: an overview of use cases and solution packages for industries, utilities and project developer – with prime examples on how it all works. 

Hydrogen for a sustainable and secure energy transition

Combating climate change requires the decarbonization of economic systems worldwide including all carbon-emitting sectors. More and more countries, regions and companies are committing themselves to climate neutrality and see hydrogen as key energy carrier to reach net zero CO₂ emissions in the future for those sectors in industry, mobility and energy that cannot be decarbonized by electrification.
