Multi Source Energy Storage System Integrated in Buildings

Share this Post:
MESSIB is an EU funded project based on a new type of energy efficient buildings with thermal and electrical energy storage capacity. The overall objective of MESSIB project is the development, evaluation and demonstration of an affordable multi-source energy storage system (MESS) integrated in building, based on new materials, technologies and control systems, for significant reduction of its energy consumption and active management of the building energy demand. MESS is composed by two thermal and two electrical storage systems, integrated with the building installations and a control system to manage the building energy demand.
This new concept will reduce and smartly manage the electrical energy required from the grid favouring the wider use of renewable energy sources in any type of building and district level. It will reduce raw material use for thermal performance and improve the indoor environment, the quality and security of energy supply at building, including Cultural Heritage, and district level.

Furthermore, a significant reduction of the energy unit cost for end-users will be achieved. To install additional conventional energy generation and distribution network assets with the capacity to accommodate to the maximum (short-term) demand is economically inefficient. Also, productivity decreases when power plants cannot operate at full capacity in periods of reduced demand. The basic idea behind energy storage in buildings is to provide a buffer to balance fluctuations in supply and demand. The demand fluctuates in cycles of 24 hour periods (day and night), intermediate periods (e.g. seven days) and according to seasons (spring, summer, autumn, winter). MESSIB systems for storing energy (thermal/electrical) will cover these cycles, with short-term, medium-term or long-term (seasonal) storage capacity.
