What is green ammonia and what role does it play in Queensland’s energy transformation?

Ammonia is a type of gas that is widely used in fertiliser and chemical industries. The storage and transport of ammonia is a mature industry and is delivered at scale through ocean tankers. 

One way of making ammonia is by using hydrogen from water electrolysis and nitrogen separated from the air. When this process uses electricity sourced from 100% renewable sources to power the electrolysis process, the end product is referred to as ‘green ammonia’.  

Ammonia has a key role to play in the green hydrogen economy because it is an efficient carrier of hydrogen over long distances. This is because, for a given transport ship size, almost twice as much gaseous hydrogen can be extracted from a liquid ammonia shipment as compared to a liquid hydrogen shipment. 

There’s a lot of exciting developments when it comes to green ammonia, including:  

  • Projects currently underway in Japan, where companies like JERA are exploring ways of co-firing ammonia in coal powered generation to cut CO2 emissions; 
  • Gas turbines also being developed to co-fire ammonia or hydrogen in gas powered generation. This will help to decarbonise and achieve emissions reductions; and 
  • New gas turbine combustor technology is being developed to reduce emissions from using ammonia as a fuel, which as a nitrogen/hydrogen compound would be a true decarbonised power source.

What is energy storage?

Put simply, energy storage is the ability to capture energy at one time of the day for use at a later time. Storage devices can save energy in many forms – the most common being battery storage – and convert them back to useful forms of energy like electricity. Energy storage involves converting energy that may be difficult to store to more conveniently or economically storable types.

It’s not just large energy companies and generators that use energy storage. For every smart phone user, it’s a part of our daily lives. We all know that our mobile phones have a rechargeable battery which stores chemical energy and is then readily convertible to electricity to operate our devices.

In fact, even the food we eat is a form of ‘energy’ stored in chemical form!

What is the TSBE hydrogen portal?

An online portal has been established for Toowoomba and Western Downs businesses so they can register for opportunities in the emerging green hydrogen supply chain.   

The aim of the portal is to get this supply chain “right” and ensure a seamless and integrated experience for people and businesses wanting to be involved in the hydrogen industry.  

Procurement officers, for example, can use the portal for services and supplies for everything from metal fabrication and heavy transport to plumbing and electrical trades, fencing and PPE. 

For local businesses, they can use it to position themselves to take advantage of upcoming projects and opportunities. 

It will also help companies such as CS Energy to uncover and best utilise local business expertise to support the construction and development of hydrogen projects.  

What benefits are there for the local community? 

The portal is a collaboration between CS Energy and the Toowoomba and Surat Basin Enterprise (TSBE) and demonstrates their commitment to link local businesses with opportunities in the hydrogen industry. 

It’s estimated billions of dollars will be invested into the green hydrogen industry across the region. This portal will help ensure local businesses understand the opportunities around hydrogen and develop their capabilities to service this growing market. 

What are the benefits to CS Energy? 

The portal’s mapping process will provide local business ‘intel’ which will be invaluable as CS Energy progresses the Kogan Renewable Hydrogen Demonstration Plant, which is the next chapter of its energy hub story in the Surat Basin.

How is the energy market changing?

The Australian energy mix is changing rapidly. Three key factors are driving this significant change – renewable generation, technology innovation, and a rise in the active and involved energy customer.

While the future energy market is uncertain, CS Energy is clear about the kind of energy business we want to be: one that’s customer focused, diversified, proactive and recognised as a leader in the Australian energy market.

This is reflected in our vision – To be a leading provider of diversified energy solutions to our customers.

How are customers driving this change?

All over the world, customers are demanding greater performance from their energy providers, whether that is cost efficiency, environmental impact, reliability of energy supply or transition to renewables. 

Australian consumers are at the forefront of this change, and energy producers must adapt and respond to these increasing expectations from our largest to our smallest customers. 

As an established energy company, what is CS Energy doing to adapt to this change? 

As a major electricity provider, it’s critical that CS Energy maintains and invests in our existing assets so they perform at their best to power homes and businesses. But we must also leverage new technology, business models and partnerships to create a long-term future for our business.  

How does CS Energy make this transition to the “energy of the future” while still delivering what customers need for today? 

CS Energy’s approach is built on our purpose: Delivering energy today, powering your tomorrow.  

This purpose captures the dual nature of what we aim to do – run a successful energy generation business that meets the needs of Queensland businesses and communities, while at the same time evolving into a truly diversified energy business. 

What does this mean in practice?

As a key driver in this transition, we are: 

  • Strengthening our foundations with a focus on safety, people, culture, community and environment
  • Optimising our assets and focusing on high availability and reliability and being flexible as energy demand changes due to renewables
  • Maximising our returns, so continue to run a commercially competitive business, with a strong cost focus and a disciplined approach to investment decisions
  • Delivering future energy and pursuing diversification opportunities that expand our customer base, leverage technology and renewables, and respond to opportunities in distributed generation.

Electric Vehicles FAQ

What’s the difference between AC and DC electric vehicle chargers?

Difference between AC and DC chargers

As part of our retail offerings for large energy users, CS Energy has partnered with industry leaders Jet Charge and EVSE to offer a suite of low-cost, simple charging products that takes the hassle out of switching to electric vehicles for your organisation.

When considering a switch to an EV it’s important to consider the type of charging requirements of your business.

CS Energy offers two EV charging technology options for customers, based on their specific business needs.

The first is a direct current (DC) charger, which is what you will find at most fast-charging public facilities. DC chargers provide the fastest charging of EVs, which is particularly important when driving longer distances.

In 2020, CS Energy commissioned a DC charger at Kogan Creek Power Station for use by employees who drive EVs to the site, which is a four-hour drive from CS Energy’s corporate office in Brisbane.

The second is an alternating current (AC) charger, which are more commonly used in residential, fleet and inner-city locations. AC chargers are perfect for topping up your vehicle when you need to drive shorter distances, or for charging overnight.

  • The Kogan Renewable Hydrogen Project will ensure CS Energy has the technical capability to enter the hydrogen market once it becomes more commercially viable. The project will be one of the first renewable hydrogen projects to come online in Queensland, with the first hydrogen expected to be produced in 2023.
Electric Vehicles FAQ

How far can you really go in an electric vehicle?


This year, CS Energy has installed 7kW and 22kW AC chargers at prime inner-city locations so Queensland Government fleet drivers can ‘top up’ their electric vehicles (EV).

In one hour, a 7kW charger adds enough power to drive a typical EV 50 kilometres, or from Brisbane’s CBD south to Yatala or north to Caboolture.  In the same period, a 22kW charger adds enough power to drive 160 kilometres dependent on the vehicle.

Queensland has had more than a thousand new electric vehicles registered in the past year as they become more popular and accessible.

EV uptake Australia wide is also gaining momentum as organisations move to upgrade fleets to position themselves for the future by reducing costs and their carbon footprint.

Who is bearing the cost of this class action?


CS Energy is a Queensland Government-owned business, so Queenslanders are already bearing the costs of defending against what will be a long and complex case.

Queenslanders would ultimately also bear the costs of any class action pay-out, including from CS Energy profits which are otherwise returned to government to pay for schools, hospitals and roads.


Who benefits from litigation-funded class actions?


The Australian Law Reform Commission reported that the median return to class action members was 51% of the settlement award when corporate backers were funding the action, and 85% of the settlement award when corporate backers were not involved.


Has the class action court process started?


The first case management hearing, which simply deals with procedural matters and the way the matter will progress, was held recently. This is the first step in what will be a long and complex legal process.
