Natural gas, which is the main material of city gas and generates the least CO2 (carbon dioxide) when burned compared with coal and petroleum, is a fossil fuel with excellent environmental features.
Use of natural gas at factories, commercial and medical facilities, etc., which need lots of energy, contributes to environmental conservation and energy conservation.
Aiming to further energy conservation and financial efficiency in addition to environmental characteristics, we propose high-efficiency equipment and systems.

Natural gas vehicles (NGVs) do not discharge SOx (sulfur oxide), soot, and other particulate matters. In addition, they emit less NOx (nitrogen oxides) and CO2 (carbon dioxide) compared with gasoline-powered vehicles and diesel vehicles, thus presenting excellent environmental features. NGVs are also characterized by a rich variation in vehicle types, from trucks and buses to light automobiles, compared with other low-pollution vehicles.
