Under the agreement, Hygen Power will be responsible for installing and operating a fuel-cell power generator unit at PTT's Research and Technology Institute in Amphoe Wang Noi, Ayutthaya, as well as supplying the generator and the power meter, connection to the power grid, power-generating operation, along with system maintenance. PTT is to secure a location for the generator, supply natural gas, lay gas distribution lines equipped with the required meters and apparatus, and maintain the gas distribution system together with associated apparatus.

The two firms will collaborate in further investigating and developing the project, which contributes to Thailand's energy security amid rapidly-rising power consumption that accompanies an expanding economy. They will also set up a joint task force to review evolving results from the project and consider suitable future actions.

This gas-fired fuel-cell power generator is the most advanced and Thailand is the second country after Japan to investigate and develop the project in the region of Asia. With a capacity of 250 kilowatts and a 48% power-generating efficiency, the project is designed to generate 1.8 million units a year of electricity for use in PTT's engine-testing facility at the Institute. Its consumption of natural gas will amount to 50,000 cubic feet per day. This collaboration spans 10 years.

As the fuel-cell system relies on chemical reactions without any combustion, it creates no environmental impacts. The reaction water and heat can be used in absorption chiller units for air conditioning, thereby saving expense needed for that purpose. In Europe, the US, and Japan, such a system is classified as power generation using alternative energy along with solar and wind energy, against both of which the fuel-cell system provides a more uniform flow of electricity generation.
