ENERGY

Energy

Carbon capture & storage

A technology to collect, compress and store liquid carbon dioxide, generated from most industrial processes of the electricity generation, petrochemical and steel manufature plants, before emitting into the air.

Wet capture techniques 

The wet capture process is to collect carbon dioxide from the general exhaust gas by absorbing it with wet-type absorbents.


Dry capture techniques 

The dry capture process is to collect carbon dioxide by absorbing it with dry-type absorbents instead of wet-type ones.

Fuel cell power generation

A fuel cell is used to convert the chemical energy which is generated by chemical reactions of hydrogen and oxygen into electricity.

Phosphoric Acid Fuel Cell (PAFC)

uses phosphoric acid (H3PO4) as electrolytesand is operated at a low temperature of about 150-200℃. It enables water cooling and  can be manufactured to be compact in size. And, it uses distributed power sources from hospitals, hotels and buildings.


Molten Carbonate Fuel Cell (MCFC)

uses molten carbonate (Li2CO3,K2CO3) as electrolytes and is operated at a high temperature of about 600-700℃. No electro catalyst is required, and it is high in power generation efficiency. And, it uses distributed power sources from apartments and large buildings.
