Decarbonization through Energy Supply

Reducing the Transportation Carbon Footprint

Reducing the Transportation Carbon Footprint

Tokyo Gas has been working on popularizing the use of natural gas vehicles (NGVs), which are clean and feature low CO2 emissions. Along with this effort, we are now laying the foundation for hydrogen supply, including technology development, in the hope of also popularizing fuel cell vehicles. Natural gas refueling stations will withstand earthquakes of a magnitude equivalent to that of the Great East Japan Earthquake and thereby strengthen national resilience.

Environmental Friendliness of NGVs

NGVs, fueled by natural gas instead of diesel or gasoline, emit only small amounts of nitrogen oxides (NOX) and release virtually no black smoke, particulate matter (PM) or sulfur oxides (SOX), which are known to cause respiratory diseases such as asthma. They release about 10% to 20% less CO2 emissions than gasoline vehicles and are recognized as environmental friendly vehicles.

New Long-Range, Heavy-Duty CNG Truck Launched (Isuzu Motors Limited)

The environmental friendliness and superior energy security of NGVs make them a highly viable alternative to gasoline vehicles, and freight trucks, buses, garbage trucks, vans and other NGVs are already in widespread use on urban roads. With fuel diversification required for long-distance, inter-city trucking, Isuzu Motors Limited released a new heavy-duty compressed natural gas (CNG) truck in December 2015. Efforts are going on throughout the logistics sector to reduce CO2 emissions and diversify fuels.

 

Contribution to National Resilience

The transportation sector is highly dependent on oil, which accounts for as much as 98% of the fuel it uses, and so the use of natural gas has been expected to expand in order to improve energy security by diversifying fuel sources. Almost all the gas supplied to natural gas refueling stations is medium-pressure gas, and the pipelines that carry it are built to withstand earthquakes of a magnitude equivalent to that of the Great East Japan Earthquake. The gas stations are capable of continuously supplying natural gas to fuel vehicles even in the aftermath of a major disaster and thus contribute significantly to maintaining the resilience of transport and logistics.
