Speaking at a roundtable on innovation in energy storage here on Monday, Minister of Environment and Water Julian Popov said that energy storage is a highly unclear and broad term. Everyone is focused a lot on lithium-ion batteries, but storage means energy being used at a time different from that of its generation. "If we look at it in that way, we will see that we are surrounded by traditional systems for storing energy," he noted, adding that innovation lies in understanding that these systems are around us, how to use them strategically as well as how to create a market for this energy and forms to store it.
The Environment Minister went on to say that energy efficiency is practically the biggest battery. The largest amount of energy is spent on heat. The biggest energy user are buildings. When a building is isolated and renewed in energy terms, it stores energy. If well isolated, the building can be heated in one moment but be warm in another. That is very important for the national energy strategy and system, Popov argued.
