Get to know your peers right from the start with this informal speed networking session.

• Gas turbines, which are a key element of today’s electricity production infrastructure, are often overlooked when developing plans for future decarbonized electricity.
• These existing assets can be upgraded to reduce carbon emissions. This can be accomplished using fuels with reduced or zero carbon content. Another option is to add a post-combustion carbon capture system.
• New gas turbines are effectively future proofed (for future reductions in carbon emissions) as they can be configured to be “hydrogen ready”.
• This presentation will provide a view of these technology options, as well as highlighting GE experience with hydrogen and similar low heating value fuels

• Benefits and opportunities
• Commercial viability

An overview of the cost-savings goals and actual achievements of an aftermarket LTSA for a two-on-one combined cycle combustion turbine plant. The major successes, the minor successes and the new procedures implemented. A fiscal overview of the program clearly show that it was a success.

The use of 3D simulation via computational fluid dynamics (CFD) or finite element analysis (FEA) is now a common place occurrence in the turbomachinery market. Whether it is designing a jet fan for ventilation or an engine for a UAV or a pump for the mining industry, CFD and FEA are used extensively, across Australia, by engineers, designers, novices and experts alike.

This presentation details such a project, with the aim of educating the audience on (i) the general simulation process (ii) the benefit to design and (iii) the resources required. What was once a tool reserved for an army of Phd’s and global corporations, is now being done on laptops and designers, throughout the country.
