Ice Energy Thermal Storage
Electrical/thermal energy stored in form of heat & cold in Ice. Heat used for rural pasteurisation or hot water. Cold storage for dairy.

Problem: What problem is this initiative trying to address?
Rural farmers have storage challenges of hot and cold. They can not do pasteurisation effectively. They tend to have refridgeration and cold storage challenges especially dairy farmers. The have electricity challenges or no electricity. They cannot compete with an industrialised farmer. They cannot thus create jobs and growth in the rural farms other than subsistance growth.
Solution Summary: What is the proposed solution? What do you see as its most promising aspects for creating shared value?
Rural farmers storage challenges. System uses water to convert to ice. This saves electrical energy in the form of heat and cold. The heat is used for pasteurisation or hot water needs. The cold is used for rural refridgeration and cold storage of dairy or food products. If the electricity falls short the system acts as a backup allowing the farmer to compete with an industrialised farmer. The system creates jobs and growth in the rural farm areas. The health of the community increases.
Impact: What is the impact of the work to date? Specify both the social and the environmental impact of your work
We have started with a pilot plant in the rural areas of KwazuluNatal in South Africa. This is a new farmer with a new herd of milk producing cows. He does not have traditional cold storage and freezers or hot water pasterurisers. The installation will allow us to gauge the effect on his setup, his growth and his progress. The health aspects of his product will be inspected by the farmers Co-Operative to ensure the quality of his product. If the quality of his product is reasonable then he will go on to produce cheese and yoghurt products
Financial sustainability plan: How is this initiative financially supported? How will you ensure its financial sustainability long-term?
The project has been aimed at a replicable and repeatable business process. It needs to be viable and beneficial for the rural farmer as well as the supplier of the system.

Unique value proposition: What makes your initiative innovative? How does your project differ from other organizations working in the same field?
We use Ice to store electrical energy - making both heat and cold. KWhs storage better than Leadacid
Founding story: Share a story about the "Aha!" moment that sparked the beginning of this initiative.
The solar PV costs for the farmers we approached was too expensive. Even with the low cost of PV Panels it was too costly due to the balance of plant costs of Inverter and MPPT charger for the batteries. The batteries have challenges with the fact that you can only get about 5000 discharge cycles before they have to be replaced. Thus the cost of storage was too high. We are using the latent heat of fusion and sensible heat to store energy when water at 0 Degrees C changes to ice - RELEASING heat to our compressor. The water can change phase without ever needing to be replaced. Water is also a lot cheaper than any chemical battery. We can run the electrical side from solar PV, generator or the local rural electricity supply
