Buildings currently consume most of the world’s electricity and as much as 50% of their consumption is to cover thermal demands. Some new developments are continually increasing electricity consumption and peak demand, and their impacts will keep growing. Excessive energy demand has significant negative environmental and economic impacts. Thus, it is imperative to implement demand response strategies that shift electricity consumption from peak to off-peak periods. 

BEST-Storage aims to achieve the goal of peak load reduction and shifting, energy saving and energy cost minimization. Long and short-term high-energy density storage solutions will be developed and demonstrated in 4 demo cases around Europe. These include a thermo-chemical, compact and efficient seasonal storage technology, plus, two concepts with phase change materials and vacuum-insulated water storage for shifting peak load demands in cold and warm applications respectively.

BEST-Storage aims at having three main impacts:

  1. Develop and demonstrate novel modular, high performance, thermal energy storage solutions (TES) for H/C and domestic hot water (DHW)
  2. Integration of the solution within the energy networks of the building and its system management should allow different functions, such as peak load reduction, energy saving, and energy cost minimization
  3. Develop and demonstrate a novel thermal energy storage system much more compact than state-of-the-art technologies, enabling the storage of heat and cold for domestic applications for periods typically of 4 weeks long

Each of these impacts is interconnected with four objectives:

  1. Demonstrate high energy density short-term and long-term storage for heating and cooling building applications
  2. Development of long-term thermo-chemical high energy density storage with a capacity of 8kW heating power
  3. Development of a short-term high energy density modular storage for peak load shifting
  4. Development of a model predictive control (MPC) for short-term storage and peak load shifting
