Spiral Foods – RockStore Project
In Shepparton, Victoria, Heliac is deploying its RockStore thermal energy storage system for Spiral Foods, delivering reliable, low-carbon steam for food production.
Spiral Foods is an Australian food manufacturer specialising in organic and natural products, with a focus on high-quality Asian ingredients. The company is committed to sustainable production and requires a stable supply of steam for its manufacturing processes.
Technical Highlights
| Charging Capacity | Storage Capacity | Discharging Capacity | Steam Temperature | Steam Output |
|---|---|---|---|---|
| 0.4 MW | up to 5 MWh | 0.8 MW | 170 °C at 7 bars | up to 1,150 kg/h |
Overview
The system is powered primarily by a 175 kWp solar PV installation, supported by the site’s existing system and grid electricity as backup. A 400-kW electric heater converts electricity into heat, which is stored and will be used to generate steam on demand, ensuring a stable and continuous supply for production — independent of solar availability.
At Spiral Foods, the steam will be used in key manufacturing processes such as cooking, heating, and sterilisation. As steam is a critical part of food production, the solution will ensure reliability while reducing dependence on fossil fuels and exposure to energy price volatility.
Benefits
- Cuts CO₂ emissions by replacing natural gas
- Stabilises energy costs through direct use of solar power
- Ensures a dependable steam supply with built-in thermal storage
- Scales and adapts to meet future production needs
