Corporate Social Responsibility (CSR) / Environmental Preservation

Companywide Environmental Targets

In fiscal year 1994, we laid out medium- to long-term initiatives with targets to be met by fiscal year 2011. In fiscal year 2007, we acquired integrated Companywide certification under ISO 14001, the International Organization for Standardization's standard for environmental management. At that time, we added a new initiative—expanding sales of environment-friendly products—to our existing basic themes, which are to prevent global warming, promote the proper management of chemical substances and advance "resource saving and recycling."

While we were essentially successful in achieving the targets we set, a number of targets were not met, including the conservation of energy at sites, a result of extraordinarily hot summer weather. We will continue to work toward these targets, guided by our environmental management system. In fiscal year 2012, we announced a number of new initiatives. In addition to reducing power consumption per unit at gas production facilities—the principal component of our environmental footprint and our most critical challenge—we will press ahead with the development of environment-friendly products and promote efforts in line with a variety of environmental themes.

New Companywide Environmental Targets

  1. Reduce power consumption per unit at gas production facilities
  2. Reduce energy consumption at gas production facilities
  3. Reduce fuel used in tanker trucks (per unit of transport)
  4. Address development themes with the potential to contribute to the environment
  5. Expand sales of environment-friendly products

Developing Environment-friendly Products

We continue to capitalize on our extensive gas control technologies to develop and market a wide range of products that contribute to environmental protection.

Innova-Jet Ultralow NOx Combustion Burner System

In 2011, we commenced sales of Innova-Jet, a revolutionary, newly developed ultralow NOx combustion burner system in which NOx exhaust is vibrated by cyclical variations in the flow of the oxidizing agent, i.e., air, and oxygen. With Innova-Jet, the production of NOx emissions during oxygen enrichment is reduced to approximately 1/20 the level of conventional NOx combustion burner systems. Thermal efficiency is also increased, reducing the amount of energy needed and minimizing CO2 emissions.

70/35MPa Hydrogen Station

The filling pressure of a hydrogen fuel tank has been increased gradually over time to extend the cruising distance* of hydrogen-fueled cars—currently the most promising environment-friendly alternative to conventional vehicles—and is today approximately 70MPa. We have responded to this trend by working to develop a hydrogen filling station that enables quick and safe refueling. The resulting mobile hydrogen station features a compact design and uses a compound vessel to reduce the weight of the accumulator. It also employs a liquefied hydrogen-type pre-cooling system. These efforts combined to facilitate a 70MPa filling.

* Cruising distance: The distance a car can travel on one tank of fuel.
