Menti Q+A
Fire safety is a critical consideration for the BESS facility. CCQ intends to use LFP Batteries which have significantly lower risk of fires. Additionally, the supplied system will be tested against international fire safety standards (UL9540A) which are aimed at ensuring any fires do not propagate to surrounding equipment.
CleanCo is aware of odour issues in the Swanbank region, and the impact that this has to nearby residents. CleanCo’s operations do not produce odour and we actively monitor all of our operations to ensure we meet environmental requirements. We actively pass on the feedback we receive from community on odour to relevant operators in the region. You can find out more about the Odour Abatement Taskforce here and report odour here or by calling 1300 130 372 (option 3).
Hydrogen is difficult to store due to its low volumetric energy density. It is the lightest and simplest of all elements, being lighter than helium, and so is easily dispersed into the atmosphere.
Another challenge is the very low boiling point of liquid hydrogen (−252.8°C), which means that it needs to be kept cryogenically stored at low temperatures.
Storing hydrogen as a gas also has its challenges as it typically requires the use of high pressure tanks (350-700 bar or 5000-10,000 psi).
Another solution for hydrogen storage is through adsorption or absorption, although with these storage techniques, further steps are then required to release the hydrogen once again.

The main additional challenge with storage of green hydrogen is the ability to match production volumes with the demand or end use. Renewable energy supply for green hydrogen production can be intermittent requiring a variable storage capacity to ensure that the end use requirements are met.
In basic terms, FCAS provides a fast, short-term injection (or reduction) of energy to ensure the power supply and demand balance is maintained on the system. A Battery Energy Storage System (BESS) is well suited to providing FCAS and it is intended that Swanbank will play a role in providing this service to the market.
The currently planned 2-hour battery (0.5C) has capacity to provide FCAS services as well as delivering much needed energy to support evening peak demand periods. Both 1C (1 hour) and 2C (30 minute) rated battery options, dedicated to providing FCAS, will definitely be considered in the clean energy hub planning process.
One key difference between flow batteries, fuels cells, and Li-ion batteries when comparing to coal is that there is not a continuous waste stream such as ash, produced during energy production. CleanCo as part of it's supplier and technology selection processes considers the whole of life, including end of life recycling or disposal. According to some of the large-scale battery manufacturers approximately 80 percent of battery materials can be recovered and reused. It is expected that circular economy drivers will change technology and resource recovery processes in the future to improve on todays standards.
This is a challenging area for all technologies, households and sectors of the economy and there is ongoing work to continue to improve sustainability outcomes.
CleanCo has policies and procedures for managing emergency events associated with its operations. It considers its own workforce to be community members and that these processes are kept relevant to ensure that workers, visitors and all host community members are kept safe. The emergency procedures are reviewed and rehearsed with the CleanCo workforce and community organisations, like QFES, on a regular basis to support this objective.
Currently there is a signficant difference between the commercial and technical readiness of alternatives to Li-Ion battery energy storage technologies, but this gap is closing. We have assessed and are actively monitoring a wide range of alternative technologies, and our current plans for our Core Business EOI process for the Swanbank Clean Energy hub is to provide the opportunity for proponents to submit proposals for the installation of grid-scale alternative battery energy storage technologies at Swanbank. This will include assessing those technologies as commercial investments or as pilot installations.

This will include assessing those technologies as commercial investments or as pilot installations. A hybrid mix of technologies will also be considered for pilot scale deployment at the site.
Water quality will be dependant on the type of hydrogen production technology selected, but currently the technologies we have investigated require very clean ASTM type 2 water. The Demineralised water plant currently on site is expected to be able to deliver water of this quality. There is a waste stream involved in the creation of demineralised water as it involves the removal of impurities in the source water. The cleaner the water input the lesser the amount of waste produced.The demin plant wastewater is disposed of by adding it to the cooling tower blowdown system and released into A Weir / Oaky Creek, in accordance with our EA.
The CIP (Clean In Place) chemicals are collected in a tank and disposed of via a waste truck in accordance with regulated waste procedures.
The Swanbank site is a heavily disturbed site from the decades of coal-fired power generation. CleanCo has ambitions to ensure that the future energy options do not impact on the surrounding environment and that opportunities to improve the natural ecology of the site are considered within the energy development options.
The design life of a large-scale Lithium-Ion battery is notionally 20 years, however this is subject to its utilisation and may be extended by up to 10 additional years.
According to some of the large battery manufacturers approximately 80 percent of battery materials can be recovered and reused. It is expected that circular economy drivers will change technology and resource recovery processes in the future to improve on todays standards.
As a Government Owned Corporation, CleanCo is required to comply with the Queensland Procurement Policy and operate within modern slavery and ethical standards guidelines.
CleanCo engages with international supply chains and seeks to align with those providers who share the same values for human rights.
