I will report Energy flow management and utilization of waste heat on behalf of civil study group of AAA.
AAA means Advanced Accelerator Association Promoting Science & Technology.
My name is Junji Sawai. I am working for Sumitomo Mitsui construction. １

2. 1. Introduction
The method of utilization of waste heat from ILC depends on the temperature and magnitude of waste heat from each sub-system of ILC.
We have investigated heat supply service and the related engineering by studying various facilities whose conditions are similar with ILC in regional characteristics.
Based on the investigation and its result, we propose:
A heat energy management service,
Supplying attractive environment to agriculture corporation,
A preceding model of utilization of waste heat for facility agriculture. 2

6. 3. Possibility of heat supply service (continued)
3.1 Agricultural complex
Study of utilization of waste heat energy for agriculture based on interview with experts
Since agricultural land area per farmer of Japan is very small, large scale facility agriculture using waste heat from ILC must be operated with a corporation.
One possible business model is to complete the facility by the corporation and lease with full turn key contract.
Government model project:
Policy of the Japanese government is also facing the large scale facility agriculture (same as above).
The unit area of the government model project is 4 ha.
Consider agricultural production and sales together
Fuel fee accounts for 30% of selling price
Therefore, the stable and low cost heat energy is very efficient. 6

8. 3. Possibility of heat supply service (continued)
3.2 Forestry: Drying timbers using waste heat from the ILC
Drying of building wood  ~Moisture contents < 10%
Woody biomass for fuel (power generation, drying, etc.)  < 30%
3.3　Inland aquaculture fishery: Example by Yumesouzou Co., Ltd.
Aquaculture of Tiger Fugues is possible
by hot water using waste heat from ILC 8

9. 4.1 Transportation of heat energy by heat insulating pipe
Morioka station
We are standing here
Pump station for sewerage
District heating and cooling plant
Heat energy is transported with pipe in this area
Long distance heat transportation is not possible (<500 m) with pipe
We need new technology for the long distance heat transportation
for ILC, because of its length (>30 km) 9

10. 4. Transportation of heat energy(continued)
4.2 Transportation of heat energy using “HAS-Clay” by container truck
Principle of “HAS-Clay”
Sintered nano-scale compound of
Hydroxy Aluminum Silicate + Amorphous Aluminum Silicate
Phase transition of H2O (Vaper ⇔ Water) + Chemisorption
HAS-Clay: “Adsorbent” developed by the National Institute of Advanced Industrial Science and Technology (AIST)
Specific gravity 1.2
Adsorbed moisture content 0.37kg/kg
Volume filling rate 50%
Heat storage density 542 MJ/m3
 12 times of energy of natural gas (45 MJ/ m3 ) 10

11. 4. Transportation of heat energy(continued)11

12. 4. Transportation of heat energy(continued)
Amount of moisture adsorption of HAS-Clay
increases monotonically as a function of
relative humidity in wide humidity range.
This means that HAS-Clay can be used
to recover
both low temperature (~65 C)
and high temperature waste heat.
