Summary from Effstock 2009
This year, the 11th international Conference on thermal energy storages took place in Stockholm – the Effstock 2009 – Thermal Energy Storage for Energy Efficiency and Sustainability.

The Effstock 2009 was held under the patronage of H.M. King Carl XVI Gustaf, the official host organisation was Swedvac, the Swedish Society of HVAC Engineers, celebrating its centenary in 2009 with a Gala Dinner in the magnificent Blue Hall of the Stockholm City Hall as an incredible highlight.
The main financial supporter was the Swedish Energy Agency. As usual, the conference had been organised in collaboration with the Storage-Program from the International Energy Agency (IEA), Energy Conservation through Energy Storage Implementing Agreement (ECES).

170 scientific papers from 31 countries have been presented, covering both, theoretical investigations and experimental research on latent, sensible and thermo-chemical Thermal Energy Storage (TES).
More than 350 participants attended the conference, which also offered a business exhibition with 29 exhibitors.
Thereby, the success story of the Stock-Conferences has been continued once more. Results from theoretical investigations as well as best-practice-examples have been presented and discussed within the community of scientists and users.

As already become visible from former conferences, the meaning of latent storages like PCM or thermochemical storages, has increased dramatically: High storage densities have a promising future, even if prices have to be reduced to be comparable to conventional water-based systems.
Success stories have also been reported about sensible underground systems and other large water tanks: Furthermore there were impressive results achieved with solar-assisted and geothermal systems. Thus it is not surprising that their markets are rising all over the world.

The different examples demonstrated, that energy storages are the key component for the energy-efficient systems of the future in the building, industrial and transport sector. However, the research on energy storage is a cross-cutting issue: Scientists from different disciplines have to cooperate with the practising experts. Basic research and development on storage material and concepts are still necessary in future, but not without having a strong focus on the economical boundary conditions.
Beyond this, research and development on energy storage cut across national borders. Within the frame of ECES experts from all over the world are working together very successfully – as the presentations from the actual seven ongoing Annexes demonstrated impressively.

To make the energy systems of the future as efficient and sustainable as possible, ECES decided to deal in future with both, thermal and electrical energy storage.
Consequently, the next Stock-Conference will be about energy storage in general.
Spain is going to host the next Stock-Conference InnoStock 2012 in Lleida.
