Two Demonstration Projects for Energy Efficiency in Thailand

As a result of rapid economic development, energy demand continues to increase in developing countries such as Thailand. However, delays in introducing energy efficiency technologies have led to excessive energy consumption and environmental issues. In order to resolve these issues, NEDO carries out demonstration projects in cooperation with host governments to introduce Japanese energy efficiency and renewable energy technologies in Southeast Asian countries. The demonstration of the effectiveness of such technologies will contribute to the resolution of energy and environmental issues as well as broad international dissemination of the technologies. (Please refer to Annex 3) Facilities for two demonstration projects in Thailand have been recently completed with completion ceremonies scheduled to be held on January 16 and 17, 2013, marking NEDO’s new activities move into full swing in Thailand.

Completion Ceremony for The Model Project for Reducing Energy Consumption in a Commercial Building in Thailand

―Introduction of Japanese Advanced BEMS Technology into Commercial Sector― The New Energy and Industrial Technology Development Organization (NEDO) is carrying out The Model Project for Reducing Energy Consumption in a Commercial Building in Thailand at the Amari Watergate Bangkok, a hotel situated in Bangkok. NEDO has entrusted implementation of the project to The Chugoku Electric Power Co., Inc. The project facilities have been recently completed and a completion ceremony will be held on January 16, 2013. The project is expected to improve the building’s energy efficiency by about 15% by replacing existing equipment, such as air-conditioning systems, with technologically advanced Japanese equipment. Using this project to establish a foothold, NEDO aims to promote the dissemination of commercial building energy efficiency technologies throughout Southeast Asia.

1. Project Overview

A memorandum of understanding for the project was concluded between NEDO and Ministry of Energy of Thailand. The Chugoku Electric Power Co., Inc. and the Amari Watergate Bangkok have been entrusted to implement the project. Thailand’s energy consumption increased about 20% during the five year period from 2003 to 2008. In particular, energy consumption in the commercial sector increased about 29%. Dues to increasing energy demand, Thailand now depends on imports for 60% of its commercial energy supply. In order to contribute to energy efficiency in the commercial sector, NEDO is carrying out the demonstration project at a commercial building, by installing Japanese advanced energy efficiency equipment and technologies. The project also aims at the dissemination of energy conservation services such as energy service companies (ESCO) in Thailand in the future. The Amari Watergate Bangkok, a hotel situated in Thailand’s capital city, Bangkok, has been selected as the project implementation site. The project aims to improve energy efficiency and reduce greenhouse gas emissions in a commercial building through the introduction of high-efficiency equipment, inverters to reduce transportation power, renewable energy technologies such as heat pumps, and building energy management system (BEMS) to optimize energy control and management.

2. Attendees The completion ceremony will be held from 10 a.m. on Wednesday January 16, 2013 (local time) at the Amari Watergate Bangkok.

Completion Ceremony for Thailand’s First Clathrate Hydrate Slurry Thermal Energy Storage Air-conditioning System

-Introduction of New Energy Efficiency Technology for Air-conditioning- The New Energy and Industrial Technology Development Organization (NEDO) is carrying out The Model Project for a Clathrate Hydrate Slurry Thermal Energy Storage Air-conditioning System at the headquarters of the Electricity Generating Authority of Thailand (EGAT). NEDO has entrusted implementation of the project to JFE Engineering Corporation. The project facilities have been recently completed and a completion ceremony will be held on January 17, 2013. The project aims to introduce a thermal energy storage system for air-conditioning using clathrate hydrate slurry developed as a new refrigerant. The refrigerant utilizes TBAB*1, which stores more energy than existing thermal technologies such as chilled water storage and ice storage. This is the first thermal energy storage air-conditioning system to be introduced in Thailand. Using this project to establish a foothold, NEDO aims to promote the dissemination of energy efficiency air-conditioning technologies throughout Southeast Asia.

1. Project Overview

A memorandum of understanding for the project was concluded between NEDO and the Ministry of Energy of Thailand. JFE Engineering Corporation and the Electricity Generating Authority of Thailand have been entrusted to implement the project.

The project uses the result of a collaborative project carried out between NEDO and JFE Engineering Corporation from FY2001 to FY2003. In FY2006, technology developed through the project was awarded the Prime Minister’s Prize at the Japan Industrial Technology Grand Prix. The technology was independently developed in Japan and has advanced energy efficiency capabilities.

The project utilizes this technology to introduce a thermal storage system for air-conditioning using clathrate hydrate slurry developed as a new refrigerant. The refrigerant utilizes TBAB, which can store more energy than existing thermal technology such as chilled water storage and ice storage. TBAB is an advanced thermal storage material that combines the attributes of water and ice. As it stores more than double the amount of cold energy compared to water, TBAB reduces thermal storage tank space in half. TBAB’s melting point is higher than ice storage and its energy efficiency is higher than ice storage. TBAB enables a refrigerator to operate at temperatures higher than ice during night-time heat storage and improves its coefficient of performance (COP*2).

Benefits of the technology introduced in the project include the following:

⁃ Latent heat storage of around 7%, which is near the temperature range of air-conditioning

⁃ Refrigerators can operate most efficiently during night-time heat storage ⁃ Improved efficiency as refrigerator operates at night when outside temperatures are low ⁃ Reduced size compared to non-thermal storage refrigerators ⁃ Reduced size of power receiving equipment ⁃ Reduced heat storage tank size as the refrigerator has two to three times higher heat

density than cold water
