Summary:

Australian Government and international policies are continuously emerging to support a green hydrogen industry. A global target of low-cost hydrogen (below $2/kg) is currently in place to help industries achieve decarbonisation goals by adopting hydrogen at scale.

CSIRO, Australia’s national science agency, and RFC Ambrian have co-founded Hadean Energy, a new company aiming to commercialise tubular solid oxide electrolysis (SOE) technology.

CSIRO’s SOE technology can produce hydrogen with 30% less electricity than traditional methods, and it has the potential to significantly reduce hydrogen production costs and industry emissions.

CSIRO will trial the technology at BlueScope’s Port Kembla Steelworks to demonstrate the equipment at pilot scale in an industrial environment.

The trial will commence in April 2024 and will help to demonstrate the technology at a higher scale and confirm the technical robustness of the equipment.

Hadean Energy will have exclusive rights over CSIRO’s SOE technology.

RFC Ambrian manages a decarbonisation technology fund targeting early-stage investments in emerging technologies with the potential to decarbonise high emissions industries.
Stefan Skorut, RFC Ambrian’s CIO, said the technology is well placed to address the existing industrial hydrogen market, which is currently almost 100% derived from fossil fuels.

Here are some additional key points from the article:

The SOE technology can be used to produce hydrogen for a variety of applications, including low-emission steelmaking and heavy transport.

The technology is free of platinum group metals and nickel, which reduces reliance on international supply chains.

The trial with BlueScope is expected to help to accelerate the commercialisation of the SOE technology.

Overall, the development of the SOE technology is a significant step forward in the decarbonisation of heavy industry. The technology has the potential to significantly reduce hydrogen production costs and industry emissions, and it is well-placed to address the existing industrial hydrogen market.

Solid oxide electrolysis (SOE) is a technology that uses electricity to split water into hydrogen and oxygen. The process takes place in a solid oxide electrolyzer, which is a device that contains a solid oxide electrolyte, such as yttria-stabilized zirconia (YSZ). The electrolyte is a material that allows ions to flow through it, but not electrons.

When an electric current is applied to the electrolyzer, the ions in the electrolyte move from one side of the device to the other. This movement of ions creates a voltage difference, which causes water molecules to split into hydrogen and oxygen molecules.

SOE is a promising technology for producing hydrogen because it is highly efficient. The efficiency of SOE can be as high as 80%, which means that 80% of the electricity used to power the electrolyzer is converted into hydrogen.

SOE is also a versatile technology. It can be used to produce hydrogen for a variety of applications, including fuel cells, ammonia production, and steelmaking.

However, SOE is also a relatively expensive technology. The cost of the electrolyzer and the operating costs are still high. As a result, SOE is not yet widely used for hydrogen production.

However, the development of new materials and manufacturing processes is expected to reduce the cost of SOE, making it more competitive with other methods of hydrogen production.

Here are some of the advantages of solid oxide electrolysis technology:

High efficiency: SOE can be as efficient as 80%, which means that 80% of the electricity used to power the electrolyzer is converted into hydrogen.

Versatile: SOE can be used to produce hydrogen for a variety of applications, including fuel cells, ammonia production, and steelmaking.

Environmentally friendly: SOE does not produce any emissions, making it a sustainable way to produce hydrogen.

Here are some of the challenges of solid oxide electrolysis technology:

Expensive: The cost of the electrolyzer and the operating costs are still high.
Not yet widely used: SOE is not yet widely used for hydrogen production due to its high cost.
Research and development: More research and development is needed to improve the efficiency and reduce the cost of SOE.

Some Hydrogen powered cars can go up to 100 miles or more on a single kilogram.

The Toyota Mirai, for example, has a range of 650 kilometers (404 miles) on a full tank of hydrogen, which is about 5.6 kilograms. This means that the Mirai can go about 115 miles per kilogram of hydrogen.

The Hyundai Nexo has a similar range, at 609 kilometers (378 miles) on a full tank of hydrogen. This is about 109 miles per kilogram of hydrogen.

The actual range of a hydrogen-powered car will also depend on the driving conditions. For example, driving at high speeds or in cold weather will reduce the range.

Overall, hydrogen-powered cars have a range that is comparable to gasoline-powered cars. However, the infrastructure for hydrogen refueling is not as widespread as gasoline refueling, so hydrogen-powered cars are not yet as widely available.

Here are some additional factors that can affect the range of a hydrogen-powered car:

The weight of the car
The aerodynamics of the car
The efficiency of the fuel cell
The temperature of the fuel cell
The pressure of the hydrogen gas

As the technology continues to develop, the range of hydrogen-powered cars is expected to improve.
