HEAT PUMPS FOR INDUSTRIAL AND COMMERCIAL APPLICATIONS
Decarbonising process heating and cooling is a critical challenge as we work towards net zero targets. Australian industry accounts for 44% of the nation’s end-use energy and 52% of that is for supplying process heat with natural gas as the leading source of energy.
Already there are commercial, proven industrial heat pump and thermal battery technologies that can supply required process heating and cooling, as well as the energy reliability and flexible to maximise renewable and demand response benefits.
Heat pumps can be used for a range of industrial, commercial and residential applications, for providing both heating and cooling. ​Until recently, heat pumps were only considered viable for lower (less than 120 °C) temperatures, however, that temperature range is increasing with high temperature heat pumps now being developed and tested for high-heat applications such as drying of building products.
How heat pumps work
Heat pumps are a class of active heat-recovery equipment that allows the temperature of a waste-heat stream to be increased to a higher, more useful temperature. Many heat pumps also operate in the opposite direction to provide cooling. Refrigerators and reverse-cycle air conditioners are examples of heat pumps that we use in our every day lives.
​
As well as already being very efficient, heat pumps are electrically powered, enabling them to be powered by on-site (and off-site) renewable generation, such as solar PV. Combined with thermal batteries, heat pumps can supply heating and cooling efficiently and economically when it is needed enable participation in demand management arrangements to take advantage of incentives.
Tools for planning industrial and commercial heat pump systems
Heat pump refrigerant guide
As part of the RACE for 2030 Decarbonising Heat with Heat Pumps project, A2EP has developed a guide for installers which explains the limitations of certain refrigerants due to issues such as flammability and global warming potential (GWP) and a refrigeration choice decision tree to simplify the selection process. ​Download the Heat pump refrigerant guide.

Access A2EP's online Heat Pump Estimator
Our Heat Pump Estimator tool has been designed to aid Australian businesses in sizing heat pumps to replace gas boilers in a bid to reduce energy costs and decarbonise operations to meet net zero targets. ​This simple-to-use online tool gives business decision-makers the basic information they need to understand if a heat pump system is technically and economically viable for their business, and to start a conversation with an energy consultant or heat pump provider and get the ball rolling. ​Access the Heat Pump Estimator
A2EP's work assessing and promoting the potential for heat pumps
Our research and demonstration projects looking at the potential of heat pumps to decarbonise industrial process heating and cooling extends back more than. We have produced a number of respected reports and worked on several key government projects looking at heat pumps. See below for more information and links to the reports and project outcomes and watch our recent webinar update on our renewable heat work with governments and industry.
Australian Heat Pump Roundtable
​
In 2023, A2EP established the Australian Heat Pump Roundtable to bring industry leaders and government representatives together to identify and discuss ideas for accelerating the transition to heat pumps in Australia's commercial and industrial sectors - as well as the obstacles that need to be overcome. The first meeting of the Roundtable was held in Sydney on 26 July and featured representatives from five different government agencies, industry associations for commercial and industrial sectors, four different research organisations, energy suppliers, finance, OEMs, consultants, contractors and finally end users across a broad spectrum of commercial and industrial sectors.

Renewable Energy for Process Heat Opportunity Study
In early 2019 with funding from the Australian Renewable Energy Agency (ARENA), A2EP initiated a project to determine the technical and commercial feasibility of replacing fossil-fuelled process heating technologies in manufacturing settings with renewables-powered alternatives, and to detail pathways to implementation including technical specification and a business case for investment.
​
A report delivered at the end of the study drew on the findings of 20 pre-feasibility studies and seven feasibility studies to demonstrate the economic and technical feasibility of heat pumps for low temperature heating applications. It identifies challenges to heat pump implementation and measures to address these challenges. ​Read the final report.
Futureheat.info web resource
As part of the Renewable Energy for Process Heat Opportunity Study project, A2EP developed the FutureHeat.info website to help build awareness of the benefits of industrial heat pumps, thermal batteries and other technologies to deliver renewable process heat and to build industry capacity for implementing these solutions across the country. The website includes technical information, case studies, tools and industry reports. ​Visit the FutureHeat website.
Harnessing heat pumps for net zero report
​
A2EP and the Energy Efficiency Council (EEC) joined forces to release a report – Harnessing heat pumps for net zero: The role of heat pumps in saving energy and cutting emissions. ​The research spotlights the critical role of heat pumps in the energy transition. The opportunity for heat pumps to help decarbonise key industrial subsectors is substantial; the report finds that emissions reductions of 391 Mt CO2-e in industrial processes are possible to 2050. Read the report.

Heat pump feasibility study for the NSW Government
As part of our ongoing work supporting state governments to deliver business decarbonisation and net zero programs, A2EP is delivering a heat pump feasibility study funded by the NSW Government. We visited the a2 Milk Company processing facility in Smeaton Grange, with several clean technology leaders including pitt&sherry, gTET (green Thermal Energy Technologies) and Minus40 Consulting Engineers.

Technical guidelines for air source heat pump water heaters
In 2022 A2EP was engaged by the Victorian Department of Environment, Land, Water and Planning (DELWP) to develop technical guidelines for commercial and industrial air source heat pump water heaters. The guidelines feature sector-specific advice and case studies for heat pumps in agriculture (dairy farms), aquatic centres and multi-unit commercial buildings. Along with the guidelines, A2EP delivered two webinars in support of heat pump activity under the Victorian Energy Upgrades.
Download the Technical Guidelines (PDF).

Heat pumps for aquatic centres
​
With gas prices rising rapidly, aquatic centres are a source of high costs and emissions for councils, swim schools and private schools. More and more are looking at heat pumps as an alternative efficient source of water heating which can enable the electrification of these facilities, utilisation of on-site renewable generation and as a way to use waste heat from other processes. While converting is not simple, it is not as costly as some may think.
A2EP has delivered a number of webinars and materials specifically looking at how to approach switching aquatic centres to heat pumps.

2xEP High temperature heat pumps for the Australian Food Industry report
​
With its partners, A2EP developed this report in 2017 to define the likely feasibility and range of applications for heat pumps in the food industry, with a focus on high temperature (HT) heat pumps delivering useful heat at 66 °C - 150 °C. This work was a continuation of the 2xEP project investigating the opportunities for innovation in technology/business models that could transform energy productivity in the food value chain. Heat pumps were identified as a key technology to enable the electrification of the food processing with their ability to recover heat from waste streams to boost temperatures, displace steam, and in some cases simultaneously provide process cooling.
