Residential battery storage systems are an excellent tool for homeowners to increase renewable energy self-consumption. However, their role becomes truly meaningful during a grid outage. While mainstream battery storage inverters now commonly offer an Emergency Power Supply to support critical loads, a key question remains: how does maintaining this ‘backup readiness’ actually impact the long-term efficiency and day-to-day operation of the system?

Hybrid Energy Storage Systems is carrying out research on the conversion of surplus renewable energy into hydrogen. This is an increasingly important means of reducing wasted energy, as Malta invests heavily into renewables. Jonathan Firbank speaks with project investigator Prof. Ing. John Licari about this project and Malta’s changing energy landscape.

Using renewable energy, like solar photovoltaic, to generate electricity for direct use and to electrify other sectors significantly reduces greenhouse gas emissions. Yet, the intermittent nature and dependence on solar irradiation – the amount of energy the sun puts out at a time – complicate the operation of the power network. Home battery storage systems can assist in multiple ways.
