Time to decarbonise heating and cooling processes

Welcome to ARENA Insights - a newsletter dedicated to sharing knowledge and insights directly with industry.

A2EP raise awareness of renewable energy opportunities for process heating

Industrial process heat accounts for over 40% of fossil fuel use in industry. The Australian Alliance for Energy Productivity (A2EP) has conducted 27 studies to investigate renewable process heating technologies across a range of food, beverage and industrial processes. The studies show that industrial heat pumps are suited for low temperature heating applications and are economically and technically feasible for processes operating at temperatures lower than 90˚C.


A2EP’s Final Knowledge Sharing Report, as well as their new website called Future Heat, helps reduce barriers to the adoption of heat pumps and raises awareness of process heat alternatives for decarbonisation. Two sites are already planning the transition to renewable process heat following A2EP-led studies: Hardwick Meatworks in Victoria’s Macedon Ranges and the 3 Ravens Brewery in Melbourne’s inner-north.

Innovation in HVAC&R: AIRAH updates and spotlight interview

The Australian HVAC&R sector consumes around 22% of all electricity produced and is responsible for around 50% of peak demand on the electricity grid. ARENA has co-funded the Affordable Heating and Cooling Innovation Hub (i-Hub), coordinated by the Australian Institute for Refrigeration, Air-conditioning and Heating (AIRAH), to work on a number of projects to demonstrate how renewable energy technology can be optimally integrated with HVAC&R equipment.


Read our spotlight interview with Vincent Aherne, Project Lead at i-Hub, to learn about enhanced demand response, load flexibility, renewable energy uptake and integration of various technologies

ARENA Insights Webinar

Awards and lessons learnt from Glaciem’s PCM Thermal Energy Storage project

The lack of economically-viable energy storage is a significant hurdle for many HVAC&R end users, preventing industry transformation from the existing heavy reliance on grid energy consumption for the sector. The Advancing Renewables with Phase Change Material (PCM) Thermal Energy Storage (TES) project integrates innovative Glaciem PCM technologies with solar PV and low-cost TES batteries.


The innovation has been recently recognised by AIRAH’s 2021 awards for: Excellence in refrigeration; Innovative use of renewable energy in HVAC&R, and Excellence in Innovation.


The first Lessons Learnt Report provides insights on the development, installation, and commissioning of TES and advanced control and forecasting algorithms integrated with solar PV, existing refrigeration infrastructure and system control integration.

Australia’s first zero emissions aquatic centre

Municipal aquatic centres are the highest energy consuming and greenhouse gas emitting facilities managed by councils. As part of a net zero emissions commitment, Brimbank City Council is looking to adopt an ‘all-electric’ equipment model for its aquatic centre by installing a high tech heat pump paired with a heat recovery system, above ground thermal storage “battery” and digital control system.


The project’s first Lessons Learnt Report discusses the heat pump and thermal energy storage options considered as part of the design process and identifies opportunities to improve energy performance and environmental outcomes on future projects.

  • The Distributed Energy Integration Program (DEIP) hosted the DEIP CEO Forum, a virtual meeting of the CEOs and senior representatives in DEIP. The CEO Forum discussed progress in the previous year and the upcoming priorities. View the presentation
  • The DEIP Dynamic Operating Envelopes (DOE) workstream has consulted on the role of DOEs in Australia’s future power system.  Read the latest outcomes summary report about the use of DOEs for export management and the actions needed to implement a nationally consistent model for DOEs that will work in consumers’ interests.
  • Monash University is partnering with global technology and consulting company Indra for the Smart Energy City project to develop a grid interactive microgrid at Monash University’s Clayton campus. This will maximise the use of DER and loads in a coordinated way through Indra’s OneSait AGM technology platform and development of a Transactive Energy Market. Read the project’s Introductory Report.
  • United Energy is investigating the technical and commercial feasibility of using pole-mounted batteries connected to the low voltage network to manage constraints and increase the hosting capacity of renewables. Read United Energy’s second lessons learnt report.
