Ambient Electrochemical C-N Coupling via Co-electrolysis of N2 and CO2. To overcome the hurdles in N2 fixation (massive energy consumption and CO2 emission), investigators creatively hypothesize that the simultaneous electrocatalytic coupling of N2 and CO2 would enable the selective formation of N-products and thus realize their conversion into N--fertilizers and acetamides. Based on the CI's recent discoveries, this project will develop an innovative / sustainable system, which could promote th ....Ambient Electrochemical C-N Coupling via Co-electrolysis of N2 and CO2. To overcome the hurdles in N2 fixation (massive energy consumption and CO2 emission), investigators creatively hypothesize that the simultaneous electrocatalytic coupling of N2 and CO2 would enable the selective formation of N-products and thus realize their conversion into N--fertilizers and acetamides. Based on the CI's recent discoveries, this project will develop an innovative / sustainable system, which could promote the N2 fixation along with CO2 conversion process, a significant alternative approach to simplify the pathways of C-N bond formation. It will thereby contribute to mitigation of greenhouse emissions and create an ecofriendly protocol/technology for distributed production of C-N products under ambient conditions. Read moreRead less

Managing Hydrate Formation for Viable CO2 and Energy Transport. Increasing the allowable water content during the pipeline transportation of carbon dioxide (CO2) would greatly increase the viability of carbon capture and storage but would also increase the risk of CO2-hydrate blockages. Subsea methane (CH4) hydrate sediments represent a tremendous new energy resource if blockages in production pipelines can be avoided. Conventional oil industry approaches to hydrate avoidance are of limited rele ....Managing Hydrate Formation for Viable CO2 and Energy Transport. Increasing the allowable water content during the pipeline transportation of carbon dioxide (CO2) would greatly increase the viability of carbon capture and storage but would also increase the risk of CO2-hydrate blockages. Subsea methane (CH4) hydrate sediments represent a tremendous new energy resource if blockages in production pipelines can be avoided. Conventional oil industry approaches to hydrate avoidance are of limited relevance and too expensive for these new applications. Formation probability distributions, cohesive forces and agglomeration tendencies of CO2 and CH4 hydrates are intended to be measured and integrated into predictive multi-phase flow models, enabling quantitative risk assessments of blockages in CO2 transport or hydrate production pipelines.Read moreRead less
Improved models of nanoporous carbons for greater fundamental insight and better sustainable technology. Storage of hydrogen and energy from intermittent sources like solar and wind, and 'carbon capture' from coal-fired power stations are essential requirements for a sustainable future. A state-of-the-art computer model will be developed and demonstrated to help deliver these and other technologies for a safe and sustainable future.
Controlling nickel-base alloy high temperature corrosion in CO2-rich gases. Coal provides cheap energy for Australia but emits carbon dioxide (CO2) in large quantities. The solution is to improve the efficiency of coal fired power plants and use CO2 capture technology. This is feasible by raising steam temperatures and using oxyfuel process where coal is burnt in oxygen rather than in air. Thus the hot combustion gas is very rich in CO2 plus water vapour, which is however very corrosive at high ....Controlling nickel-base alloy high temperature corrosion in CO2-rich gases. Coal provides cheap energy for Australia but emits carbon dioxide (CO2) in large quantities. The solution is to improve the efficiency of coal fired power plants and use CO2 capture technology. This is feasible by raising steam temperatures and using oxyfuel process where coal is burnt in oxygen rather than in air. Thus the hot combustion gas is very rich in CO2 plus water vapour, which is however very corrosive at high temperatures. Traditional steels are inadequate. Instead, nickel-base alloys are needed. This project aims to investigate the corrosion behaviour of nickel base alloys in carbon dioxide - water atmospheres, and ways of preventing this corrosion by controlling gas composition and appropriate alloying, which is essential for next generation power plant design.Read moreRead less
