Energy storage to meet increasing demand is vital to developing a low-carbon energy system, and can providemore flexibility and balancing to the grid, as well as providing a means of coping with increasing use ofintermittent renewable energy. Locally, it has the potential to drastically reduce energy costs for businessesand homes. Current commercial-scale storage solutions are too early in their development & storage costsoutweigh energy savings so commercial mkt uptake has been very limited. To be cost competitive, cost perkWh must be lower than off-peak electricity prices (£0.07/kWh). Helios Limited, a micro SME, are seeking totest the feasibility of developing a combined heat & power energy storage system (TESS). The device will besmart-enabled, and will utilise off-peak electricity to store heat energy at ~£0.02/kWh in a high densitymedium. The device will use a Sterling motor to generate electricity at peak hours, and heat losses will be usedto heat a water matrix for heating or hot water. The device will also have the ability to feed energy back intothe grid if needed, and store energy from renewable energy sources such as solar PV.
