  • I still can't believe how great this worked. My drill battery, several AA and AAA batteries, and my camera battery work great again! This is super fun to do too. ▲▲▲ https://tinyurl.com/rtswhls

  27. 27. 27Dr. Luisa F. Cabeza – October 2019 Contents • The role of TES in the energy system • TES in microgrids • Outlook
  28. 28. 28Dr. Luisa F. Cabeza – October 2019 Outlook • TES can be implemented with several technologies in many applications • It is usually a custom made designed system, which it makes market deployment more difficult • TES has a clear role in the energy system • The use of TES in micro-grids confirms this statement • Some TES technologies are mature and in the market • More research is needed to develop other TES technologies
  29. 29. 29Dr. Luisa F. Cabeza – October 2019 Outlook Crosscutting Strategic Research Priorities – RHC Platform • Improving the properties of TES materials is important, in particular concerning their stability and the number of charging and discharging cycles they can withstand • The durability of new systems and their constituent parts must also be accurately quantified in order to estimate their long-term performance • Realising the great potential of TES will require research focused on the integration and optimisation of heat/cold stores with renewable energy technologies • A “system-level perspective” is needed, taking into account the heat demand patterns of all consumers connected to the system, as well as the interaction with the building envelope and the energy networks
