Heat is used in food manufacturing, such as greenhouses.Why is heat as important as electricity to our storage solution?

It is easy to underestimate the sheer volume of energy used globally to produce heat. From district heating to industrial food processing; greenhouses to manufacturing paper; beer brewing to textile production; every process uses energy to make heat. Generation of heat can account for up to 92% of the total energy requirements for industry, services and households.

In industrial processes alone Australia uses over 53 GWh of natural gas per annum, much of which is used to produce heat.

Unlike other energy storage solutions, 1414 Degrees’ Thermal Energy Storage Solution/s (TESS) can supply useful clean heat or steam for these processes without the need to convert back to electricity.

This form of energy will replace the need for gas and other electricity sources to be converted to heat or steam. Clean, cheap heat for industry, process heating, district heating, agribusiness and more.

This is why our efficiencies are measured on combined heat and power (CHP) – the efficiency of both outputs, not just electricity. In fact, many of our customers will require more energy in the form of heat than electricity. Our devices are designed to have flexibility in what energy output ratios are desired by the customer.  The prototype testing has achieved over 80% CHP efficiency and the aim for the larger systems is up to 90% CHP.

Heat production in industry will be revolutionised.
