Corporate Social Responsibility (CSR) / Environmental and Social Report 2014

Companywide Environmental Targets

In fiscal year 2012, we established new medium- to long-term targets and identified the prevention of global warming as our single most important basic theme. We will also continue taking decisive steps to address our other basic themes.

Hydro Shuttle® Package-Type Hydrogen Refueling Station

The Hydro Shuttle® package-type hydrogen refueling station integrates the four major components of a hydrogen refueling station-dispenser, pre-cooler, hydrogen compressor and storage-into a single unit. These compact (7 m × 2 m × 2.6 m) units can be used not only as permanent stations, but also as truck-mounted mobile stations. The package format significantly reduces cost of installation, while the simplification of components means the cost of fabrication is only half that of conventional permanent stations.

Because it can be used as a mobile station, a single Hydro Shuttle® offers promise for multiple applications, including on-site stations equipped with hydrogen production facilities, offsite stations that supply hydrogen produced at facilities elsewhere and travelling stations that transport hydrogen from one location to another.

Ultralarge-Scale Air Separation Unit

Our most advanced ultralarge-scale air separation unit delivers outstanding energy efficiency, consuming 15% less energy per unit of production than its predecessor. This accomplishment reflected the following key improvements:

  • An increase in the size of the unit and of the air compressor therein, which bolstered operating efficiency;
  • A reduction in air compressor power requirements achieved through the use of a low pressure-loss packed column; and
  • A reduction in air compressor power requirements attributable to the use of a downflow condenser reboiler.

Low-Cost Biogas Refining Unit

Our biogas refining units, which employ ordinary-pressure regenerative pressure swing adsorption (PSA), are capable of increasing the purity of methane gas to 98% or higher. We recently developed a low-cost compact unit suitable for the small- and medium-scale decentralized biogas plants used by dairy farmers and food processing factories. Because high-purity methane gas separated and refined from biogas is suitable for applications that conventionally depend on city gas, it offers promise as carbon-neutral energy that can be produced locally for local consumption. In Japan, tests are currently under way to determine the feasibility of supplying methane produced from biogas and city gas using the same distribution networks, underscoring the potential of biogas-derived methane to contribute to environmental preservation.

Environmental Accounting

We commenced the full-scale application of environmental accounting in fiscal year 2002. In fiscal year 2003, we began measuring investments in and costs for environmental initiatives with the aim of ensuring the efficiency thereof. Our environmental accounting system is based on Environmental Accounting Guidelines 2005, published by Japan’s Ministry of the Environment.

Scope of Environmental Accounting

Periods covered:
Fiscal year 2013 (April 1, 2012-March 31, 2013)
Fiscal year 2014 (April 1, 2013-March 31, 2014)

Scope of calculations:

All Taiyo Nippon Sanso sites in Japan, four domestic affiliates (Japan Fine Products Co., Ltd.; Taiyo Nippon Sanso Engineering Corporation; Nissan Transport Corporation and Thermos K.K.) and gas production companies whose operations are managed by Taiyo Nippon Sanso.

Calculation of economic benefits of environmental conservation initiatives:

  • “Profit” is profit from the sale of recycled waste from business activities with monetary value.
  • “Reduction in expenses” is calculated by comparing the reduction in payments for electric power achieved through energy-saving initiatives, adjusted for production volume as an indicator of business activities, with that of the previous fiscal year.
