Did COVID change our energy use patterns?

COVID has changed how many people's lives in profound ways. One aspect is how we work, study and use energy.This research project aims to answer two questions:Did energy use change for CBD, urban, suburbs and rural areas when we were experiencing lockdowns?If there were changes, how much has been changed and when the change happened, e.g time of a day, or day of a week?

Safe and non-flammable electrolytes for batteries

Electrolytes play a significant role in determining the performance of energy storage devices. In general, different types of liquid electrolytes have been investigated so far including organic liquids, ionic liquids, and aqueous. Among them, organic liquid electrolytes are highly flammable and volatile, while aqueous electrolytes suffer from a narrow working voltage window. IL liquid showed a promise to circumvent these challenges, however, their practical applications are plagued by the high cost, difficulty in preparation, and toxicity.This project will develop low-cost …

Development composite electrode for next generation Li-ion batteries

Australia is rich in lithium battery materials and is poised to be the world leader in sustainable energy storage. The rapid growth in the automobile and energy sector created greater demand for high-performance Li-ion batteries with high energy density. Conventional Li-ion batteries utilise a graphite anode with a limited theoretical capacity. Therefore, we need to develop alternative electrode materials with high energy density and a longer lifespan.Silicon (Si) has received attention owing to its high specific capacity at ambient temperature. …

Climate cooling or warming - study into Australian cities' long term temperature records

40% of global CO2 emission is related to buildings. Temperature is often a highly correlated factor for commercial/educational/healthcare building energy use and electricity peak demand.To forecast how temperature may change in the case of "business as usual" for the coming decades, we can study major Australian cities' long term temperature records.The two research questions for this project are:how did temperature change for Australian cities over the past 30 or more years?, e.g. for all capital cities and major regional centres.if …

High performance energy storage materials and devices

Energy storage devices, such as supercapacitors, play an increasingly important role in our daily life as a reliable energy supplier. Supercapacitors are a type of energy storage system that possess merits of rapid energy storage and release (high power density) with a cycling lifetime of ten thousand or more. Nevertheless the energy density of conventional electrochemical capacitor is quite low.This project aims to enhance the energy density of supercapacitors without compromising their power density through innovative designing and synthesising electrode …

Low cost, long life metal-ion capacitors and supercapacitors for renewable energy storage

Australia boasts rich wind and solar energy resources. To avoid fluctuations placing severe burden on the power grids, a reliable and efficient battery storage is required.The present technology based on lithium-ion batteries suffers from high manufacturing cost, poor safety and short life-span.A new kind of storage devices, metal-ion capacitors (MICs), are expected to overcome the storage and the charging speed of the traditional batteries in the near future, opening new avenues for renewable energy resources. The basic structure of MICs …

Modelling and simulation of Li Ion Capacitors

Climate driven global efforts has led to the exponential growth of renewable technologies which has spurred further research into energy storage technologies such as batteries, supercapacitors, and fuel cells alike. Of particular interest are hybrid technologies such as Lithium-ion capacitors (LiCs) which bridge the technological gaps between batteries and supercapacitors, paving the way to a best of both world solution. Within LiC research, predictive physics models based on constituent material properties are lacking.

Energy-efficient blockchain using a variant of Python

Studies find that BitCoin will soon consume more power than the entirety of Australia. BitCoin’s energy consumption is nearing 200 terrawatt hours (TWh), while Australians consumed 192 TWh in 2020.Blockchain platforms such as BitCoin and Ethereum employ a Proof-of-Work (PoW) consensus and blockchain management algorithm, which relies on a computationally expensive cryptographic puzzle. While PoW provides a strong security guarantee in a truly decentralised and public network, it comes at the cost of significant computation. This, unfortunately, does not provide …

Implementing research into clinical care: does our Tertiary Obesity Multidisciplinary Service improve outcomes beyond weight loss?

Obesity may be a barrier to accessing non-emergent surgery for conditions including hip and knee replacements, some early cancers, and kidney transplantation. Weight loss treatment is a complex intervention, with multiple components contributing to induce a weight loss response in individuals. Best practice weight loss interventions are delivered by a multidisciplinary team (MDT) - including dietitian, physiotherapist or exercise physiologist, pharmacist, psychologist, and physician.We are using an implementation science framework to evaluate the enablers and barriers to implementing best evidence …

Decision modelling in blockchain adoption and environmental implications

Due to the decentralised and immutable nature of distributed ledger systems, blockchain has become a critical priority for organisations across the world. The global blockchain market is expected to grow from $1.57 billion in 2018 to $162.84 billion by 2027.From an ecological perspective, blockchain has raised environmental concerns due to increasing computational power that is required to operate energy-intensive consensus mechanisms. However, it also has the potential to help promote renewable energy through a variety of blockchain-based use cases such …

Quantifying hydrogen hazards in QUT's H2Xport Pilot Plant using an open source deterministic and probabilistic model

QUT is constructing a new hydrogen pilot plant with several hydrogen technologies and various pipework, valves, welded joints, compression joints, storage vessel and instruments. The hazards and operability study (HAZOP) has been done and hydrogen leaks need to be quantified.A Hydrogen Risk Assessment Model toolkit will be used that integrates deterministic and probabilistic models for quantifying accident scenarios, predicting physical effects, and characterising hydrogen hazards’ impact on people and structures.

Internet of Mobile Energy

The emergence of the two-way communication model and Distributed Energy Sources (DES) is transforming traditional power systems from largely centralised energy production to more decentralised and connected management systems. This is called the 'smart grid'.As the smart grid evolves, electric vehicles (EVs) are emerging as unconventional and highly-disruptive participants in the grid that can add significant benefit and flexibility. Notably, EVs are equipped with a relatively high capacity battery that stores energy to power the vehicle.EV batteries, coupled with the …
