Hydrogen embrittlement is a major hurdle on the path to a future decarbonised society fuelled by green hydrogen. In short, hydrogen embrittles metallic components in an unpredictable and catastrophic fashion. Our research aims to achieve a mechanistic understanding of the hydrogen embrittlement process and identify material technology solutions that will enable safe hydrogen pipeline transmission and vessel storage at scale.

Australia’s gas pipeline network is worth $300-billion. The outcomes of NZI’s research in this space will protect the existing, highly valuable infrastructure from hydrogen embrittlement, ensuring the safe delivery of hydrogen fuel across the country. This will facilitate Australia’s transition to a hydrogen economy and net zero emissions.

Research themes:

• Using advanced microscopy techniques to observe the behaviours of hydrogen atoms in metallic materials and how they initiate failures at small scales
• Determining the susceptibilities of individual microstructural features to hydrogen embrittlement
• Developing a microstructural design strategy that can lead to materials with sufficient hydrogen embrittlement resistance

We're boosting the productivity and profitability of wind farms through advanced real time digital twins.

A digital twin enables a reduction in power losses due to aerodynamics interactions, fast identification of faulty wind turbines, and mitigation of excessive unscheduled maintenance and operation costs.

Our work will allow the operators of wind farms to better forecast short and long-term power outputs and so enable them to participate more effectively in the electricity markets.

The potential annual benefits to Australian wind farms range from $250 million to $1bn.

Research themes:Data Driven Computational Engineering: how can near-real time, high fidelity, physics informed data driven models transform wind farm profitability and operations?

Our research tackles the challenges surrounding the use of Powerfuels in combustion systems and fuel cells. We aim to facilitate Powerfuel production and utilisation by developing novel, efficient, and cost-effective technologies for synthesising ammonia (NH3) and enhancing carbon sequestration from point sources and direct air capture.

We are addressing fundamental issues to expedite the implementation of green fuels in combustion systems and create efficient, durable, and stable fuel-cell technologies for various applications, ranging from household power to transport. Green fuels, essential for decarbonising heavy industries, are considered carbon-neutral or carbon-negative alternatives to fossil fuels, deriving from renewable energy sources.

Production of Powerfuels research themes:

• Plasma driven electrochemical synthesis of ammonia and green fuels
• Converting organic waste resources to Biofuels and Chemicals
• Converting CO2 to chemicals including green methane, methanol formaldehyde and associated advanced catalysis
• Alternative electrolysers architectures
• Developing advanced catalysts for water electrolysis and fuel cells
• Process Systems Engineering: Systems modelling and optimisation, process design and integration, modelling power fuels eco-industrial precincts, energy from waste, and waste heat recovery
• Efficient transition of metal/carbon water splitting electrocatalysts for hydrogen production
• Development of porous electromaterials for Hydrogen Production and Energy Storage, and Low-cost, robust, high-activity water splitting electrodes
• Sustainable production of hydrogen and fuels from solid wastes, biomass, and greenhouse gas via catalytic transformation
• Low-pressure NH3 synthesis using new catalysts to enhance the energy efficiency and to promote the green production of ammonia

Storage of Powerfuels research themes:

• Developing advanced materials to store ammonia safely
• Developing and deploying new solar thermal-driven (renewable process heat) industrial processes (heat battery, Solar reactor, concentrated solar thermal processes)
• Carbon capture and utilisation (CCU) and integration with carbon market and policy: developing low emissions technology for capturing carbon emissions to produce value-added products such as fuels and chemicals

Our research aims to relieve energy shortage and improve global sustainability through converting greenhouse gas, (CO2, CH4, and NOx etc) into valuable fuels and chemicals.

Greenhouse gases conversion and utilisation are of great ecological & economic significance. Its optimal and wide utilisation could contribute to a more sustainable future and offer an opportunity for Net-Zero Industry transition.

Research themes:

• The development of novel, high-efficient technologies for the selective conversion of carbon dioxide into value-added chemicals such as methanol, ethanol etc.
• Fabricating economic and durable material for capturing and converting both carbon dioxide and methane into hydrogen and valuable chemicals.
• Exploring low-emission, sustainable, and stable technologies to produce fertiliser from greenhouse gases.
• Maximising the carbon credits and economics for GHG reduction processes.
