Decarbonisation of transport – the real costs and implications Electrification of transport is a methodology that can reduce carbon emissions and is within reach of NZ now, both in terms of supply and technology.However, it does require planning and preparation to meet the power demand, both in terms of energy and maximum demand. The upstream infrastructure required to meet this power demand is dependent on geographic-specific requirements and local lines utilities requirements. So an eBus depot in an industrial area may have little upstream reinforcing required, but a depot in an urban area may require upgrades right through to the Zone substation. This presentation looks at An very brief overview of the amount of generation required to replace imported fuels. Detail on a few case studies to show the power demand for large charging installations and the trends NZ is experiencing with respect to electrification of public transport (eBuses) and the recent progress in heavy goods vehicles. Very brief overview of eFerry development in NZ, including the shoreside infrastructure demands. Discussion on hydrogen technology developments and costing.

A new lens on vision based analysis Image processing algorithms for 2D applications have been in use in industry for almost fifty years. The release of open source libraries (e.g. OpenCV) nearly two decades ago have done much to improve the accessibility of vision based analysis in standard industrial applications. Nevertheless, the problem still persist that vision based solutions are perceived to be complex and difficult, both in implementation and subsequent maintenance. This is an unfortunate situation, because in many industrial applications where precise monitoring of product and machine are required, vision based solutions give an unparalleled advantage. Therefore the practical problem at hand is facilitating the accessibility and implementation of powerful existing algorithms to standard industrial applications. This presentation aims to demonstrate how this is currently being achieved in numerous practical applications throughout New Zealand by automation engineers who are primarily concerned with solving everyday problems in a robust and reliable manner. Mervin de Lancea received the B.Eng. degree in mechatronics engineering from Monash University in 2009, and PhD degree from University of Canterbury in 2012. His research interests at that time include Bio-robotics, human-assist robots, rehabilitation robots, and application of robotics in medicine. He was an Electrical and Controls Engineer with Scott Technology Ltd, Christchurch, from 2013 to 2021. He is currently with IFM as a Technical Engineer.
Decarbonisation Roadmap for Small and Medium Enterprises (SMEs): An Energy and Carbon Efficiency Perspective’ NZ has experienced a raft of changes both at a societal, legislative, infrastructural, and environmental level when it comes to its response to climate change and its energy and carbon footprint. However, these changes and contexts are not easily understood and comprehended by SMEs. SMEs make up 97% of NZ businesses and account for approximately 30% of the country’s business carbon emissions. Unfortunately, SMEs lack the required level of support and resources to transition to low-carbon energy sources, and unless significant steps are taken to address this gap, NZ will fall short of its net-zero goal. Haris has completed an EECA-sponsored Energy Management Graduate program at Alsco and has now transitioned into a full-time Energy Management role for Alsco NZ and Australia. Haris holds a Bachelor of Engineering (Honours) degree in Electrical and Electronics Engineering and a Master of Engineering Management from the University of Auckland.
Storage: the elephant in the room To achieve "carbon zero" by 2050 it seems that we will need 12,000 MW of wind power and solar power to provide the energy needed for the extra 4000 MW of load created by converting to electric heating and getting rid of fossil fuel generation. When the wind is blowing and the sun is shining there will be more than 3000 MW of surplus power available that must be stored so that we can keep the lights on when the wind is not blowing and the sun is not shining. It seems that providing this backup power is not in the terms of reference for the 1000 MW Onslow project. It is conceived as a dry year reserve only. But even if it was capable of providing backup for wind and solar (and this is not presently conceived) then 1000 MW is not nearly enough. The presentation will explore whether or not there are any technologies available now or likely to appear in the near future that will provide provide sufficient storage for days weeks and months that is necessary for backup because, for instance, solar power is least during winter when peak demand occurs. Alternatives to bulk storage such as nuclear power or more hydropower with storage or the imperfect option of stored gas (which European countries have now declared to be "Green") will be discussed. Bryan Leyland MSc, DistFEngNZ, FIMechE, FIEE(rtd), Is an electrical and mechanical engineer with 60 years experience in the power industry worldwide. He has specialised in power systems and the mechanical and electrical aspects of hydropower and he also has experience in virtually every renewable energy technology, thermal power generation and nuclear power. He has had an active interest in climate change for many years and has attended several overseas conferences on the subject. He is majority owner of a 1 MW hydropower scheme that he largely designed and now operates remotely. He believes that all engineers involved in power supply have a duty to ensure that, as far as possible, the public get an affordable and reliable supply of electricity. Without it, New Zealand cannot prosper.
Best Foot Forward - An engineer’s perspective on how to develop successful products. Throughout my career of mechanical engineering and product design I have had the opportunity to work in a variety of projects including the roles of designer and company co-founder. Every project I have worked on has been unique - the stakeholders and technical expertise has varied greatly along with the projects themselves. There are however common elements in projects that have succeeded and those that have not. As an engineer it is intuitive to tackle the novel and technical problems first and to let the other elements fall into place. Whilst not guaranteeing success there are activities and strategies that can improve the chances of success - this relies on a holistic approach including understanding your customer and stakeholder expectations and communicating the right aspects to make a product shine. I am happy to share my experiences and understanding of the role of technical development with my peers.

Efficiency and global warming potential – how refrigerant choices impact our environment and the heatpump systems we design. Electric heatpumps are the most energy efficient way of heating and cooling buildings in New Zealand and are key to reducing carbon emissions of building services. However, the refrigerants in these systems pose a serious environmental threat themselves, as many of them have Global Warming Potential (GWP) exceeding that of CO2 thousandfold. How does NZ regulate high GWP refrigerants and how much of them is leaked into our atmosphere? How can heatpump systems best replace fossil fuel heating applications? Bernhard is a Senior Mechanical Engineer for WSP based in Christchurch, designing and analysing mechanical building services and ventilation systems. He has studied mechanical engineering in Germany, before moving to New Zealand in 2014. He has since worked in the energy and construction industries and is involved in WSP’s decarbonisation initiatives.
Optimised condition-based lubrication of rotating equipment using IOT linked structure borne ultrasound and automated remote lubricators. Predictive maintenance (PdM) is an attempt to evaluate the condition of equipment by performing periodic or continuous (online) equipment monitoring. The ultimate goal of PdM is to perform maintenance at a scheduled point in time when the maintenance activity is most cost-effective, while maintaining the desired equipment performance threshold, and ultimately preventing specific modes of failure. The condition monitoring of rotating bearings is a well know application of structure borne ultrasound, with the ability to actively monitor friction levels and thus detect a need to address lubrication defects that if corrected in a timely fashion can prevent failure inducing defects in the bearings themselves. New IOT based solutions incorporating this ultrasound technology make this achievable today, with proven off-the shelf solutions, including the autonomous and remote lubrication of bearings based on real time friction (ultrasound) measurement.
Smart Distribution With ever increasing focus on energy saving and optimizing energy usage, it is necessary to monitor energy consumption for cutting energy bills and reducing pollution.

Generator Fuel Storage for Critical Infrastructure in NZ Demand for permanent back-up generators is trending upwards as data centres, Govt & corporates, landlords & tenants, look to have more resilient and futureproof buildings. Diesel powered gensets are still the most common, cost effective, and simplest way to achieve back up power for critical installations, and of course this raises the question of size, location, and safety around the fuel system. The WorkSafe NZ Health and Safety at Work Hazardous Substances Regulations 2017 is a very large document – all 580 pages - and can be very confusing to navigate regarding diesel storage. In this presentation Fuelchief will unpack several critical points of the regulations and discuss some of the intent and methods of best-practice, and some fool-proof ways to exceed compliance and make your design process simpler. We will also bring up the very interesting topic of future fuels, and how we see it relating to the current back up power industry. Join us for a chat to share ideas, and to learn something you may not have heard before…
