Electricity storage: status quo, trends and bidirectional charging

The trend toward private home storage systems in combination with photovoltaic systems has picked up speed rapidly in recent years. Falling system prices, targeted subsidy programs and the desire for greater self-consumption are making the use of PV storage systems increasingly attractive. The event will provide an overview of the market and price development of PV storage systems in Austria as well as their diverse areas of application. These range from private home storage to the use in an energy community, from the increase of the own power consumption to the emergency power supply.

Another approach is to use the storage capacities of electric vehicles. Bi-directional charging points and smart charging strategies enable intermediate storage of renewable electricity while meeting mobility needs. In the “Car2Flex” research project, concepts, suitable technologies and business models are being developed for various electromobility user groups, with a focus on private use.

Some of the speakers’ presentations are available for download. You can also watch the entire event on our Youtube channel.
