Heat Recovery "as a system" - new to industry case study

AMPC’s Decarbonisation Pathway has estimated that Industrial Heat pumps will need to carry a significant portion of the electrification task for red meat processor decarbonisation. Electrification makes up 16.4% of our sectoral decarbonisation strategy, and so far only one Industrial Heat Pump has been adopted by the processor sector. This single adoption case comprised a significant cost solution, and it needed the support of two substantial “one off” government grants. Most processor members will continue to experience grid gas price increases, some have experienced 100% increases since 2020. Increasing gas costs are exacerbated by Australia's expensive and trade exposed domestic gas production network, with an ineffectual domestic gas policy mechanism. It's very likely that domestic gas prices will continue to rise in a volatile manner over the medium term. For the electrification task to help contain this volatility, evidence of a more affordable, and more efficient Heat Recovery system is urgently required. This project involves implementing two heat lifts in Stage 1. The project has potential for a further Stage 2 (i.e. a novel three step heat recovery system across both stages). Stage 1 (this project) focuses on recovering low-grade heat using a best practice, two-step, closed loop, temperature lift from 15°C to 55°C , without the need for a heat pump. It is a first case study for industry, and it is more cost-effectiveness, quicker to implement, and more efficient on performance than any industry case study to date. Stage 2 (future project, not yet approved) may build on the work done in Stage 1, by adding a unique third temperature lift to elevate the water temperature up to 88°C. This is achieved through the installation of a heat pump system that will take the pre-heated water from the second temperature lift. A triple-lift heat recovery system would further improve the overall system Co-efficient of Performance (CoP) for a final temperature of 88°C. It's expected that this non-rendering small-stock case study plant will be able to offset 70% of natural gas use in Stage 1 (and a combined 95% of natural gas if Stage 2 proceeds), it will appeal to the sectors 90 small-medium sized plants without rendering, and 25 large plants that have low-temp rendering. It will have a Measurement & Verification Reporting period to illustrate the results.
