CCS - ROADMAP
Roadmap developed by a 18 partners Dutch consortium
Compact Conversion and Storage technologies for heat in the
built environment. For renovation & new built.
CCS will enable the wide introduction of renewable energy in
the Built Environment.
Storage of summer heat for use in winter time
Increased self consumption of renewable energy
Reducing future strains on the electricity grid
Significant impact on CO2 production (near zero)
MJP CCO 2016
WHY SEASONABLE ENERGY STORAGE?
• Solar energy highest potential for
sustainable future
• In NL  110W/m2 (year average)
• But low intensity when most needed
(winter time)
=> long(er) term and / or seasonal
storage!

STORAGE OF SOLAR ENERGY
Solar collector, PV + Heat Pump or
Hybrid system
Store excess heat in summer for
later use in winter (long term)
E.g. 10 GJ storage  ~10m3
system  ~1GJ/m3 guideline
MJP CCO 2016
HEAT STORAGE
Possibilities for thermal energy storage:
1. Sensible
(water)
2. Latent
(PCM)
3. Thermochemical (TCM)
1st generation: Adsorption (silica gel, zeolites)
2nd generation: Absorption (salt hydrates)
