In recent years there has been a global push to develop a viable means of storing large amounts of energy, primarily to overcome the intermittent nature of renewable energy generation, especially wind and solar. There are a wide variety of technologies being developed from large scale Lithium-Ion battery installations to storing compressed air in underground caverns (CAES). Energy storage is often described as the ‘holy grail’ of renewable energy.

1414 Degrees Ltd has entered the market with a patented system originally developed by the CSIRO. This system is a thermal energy storage system, and utilizes the latent heat of fusion of the storage material. It runs at a significantly higher temperature than other thermal storage medium, and has a very large energy density. The stored thermal energy is recovered and converted back to electricity via a turbine or heat engine.

    On initial inspection it was clear that it was far from complete. At this point ammjohn was commissioned to take over its development, from securing funding to high temperature materials testing, with a view to building a demonstration prototype model.
  • pic-370x270-latent-heat-storage-helpedammjohn have been involved with every aspect of the development and management of this project over the last 2-3 years including:
    • Developing the Business Case, assessing commercial viability
    • Marketing
    • Initiating and managing collaboration with Adelaide University
    • Identifying possible investor opportunities
    • Government Grant Applications
    • Research and Development
    • Materials Testing
    • Conceptual through to detailed design
  • pic-370x270-latent-heat-storage-outcomeHaving encountered numerous challenges ranging (both technical and commercial), ammjohn have now successfully developed and tested a small-scale prototype, providing sufficient investor confidence to finalise the design and begin construction on a full-scale prototype.

    Research into the design and materials is ongoing, leveraging the technical partnership with the University of Adelaide to maximise the potential of the project.
