NEC Platforms converts fuel for boiler equipment at Otsuki Plant to LNG *Aiming to achieve net zero CO2 emissions by 2040*
*
In order to realize a sustainable society, NEC Platforms has switched from kerosene to LNG (Note 2) as the fuel for the boiler equipment (Note 1), which is essential for achieving strict temperature and humidity control in the clean room at the Otsuki Plant. It started operation in August. This is expected to reduce CO2 emissions by 746 tons per year, which accounts for 11% of the entire Otsuki Plant. We will continue to decarbonize the energy used in our business activities and contribute to the NEC Group’s goal of achieving net zero CO2 emissions (Note 3) by 2040. *
Our environmental initiatives (production/office initiatives) https://www.necplatforms.co.jp/company/csr/environment/office.html
[Background]
The Otsuki Office has our largest clean room of 7,400 square meters, and is equipped with optical submarine equipment (optical submarine repeaters, optical submarine branching equipment) and optical communication equipment (optical submarine We mainly produce components. The clean room at our office is class 6 to 7.
(Note 4), and in order to meet strict temperature and humidity standards, the steam generated by the boiler equipment is used as a heat source. The steam heat source is not only used for
humidification, but also for the supply of warm air that quickly warms large floors, and for dehumidification by combining warm air and blowing air.
In addition, kerosene, which has been used as a fuel for boiler equipment, has a higher environmental impact than LNG due to its higher CO2 emissions.In addition, the boiler equipment itself uses a large furnace and smoke tube boiler, which makes operation management difficult. required a national qualification as a boiler engineer, as well as qualifications and advanced work skills as a facility management department employee.
[This initiative]
This time, in conjunction with updating the aging boiler equipment, we changed the fuel to LNG. Converting to LNG not only reduces CO2 emissions, but also reduces emissions such as NOx (nitrogen oxides), SOx (sulfur oxides), and soot and dust, which are generated during fuel combustion, and is expected to reduce environmental impact. In addition, the burden on equipment managers is reduced because handling qualifications are no longer required (for those who have completed special education), and energy costs are improved by introducing mechanisms to prevent energy loss, such as diagnosing steam leaks in steam piping. Masu.
These efforts have been evaluated by the Ministry of the Environment and selected for the SHIFT project (Note 5).
Newly installed small once-through boiler equipment
The NEC Group aims to achieve carbon neutrality by reducing CO2 emissions from business activities and the entire supply chain to virtually zero by 2040.
In addition to climate change countermeasures through our business, we provide value to a wide range of environmental issues, including contributing to a circular economy that aims to realize a prosperous society and environment through technological development, production, and the provision of products and solutions that are in harmony with the environment. We will continue to provide it.
That’s all
■Introduction of NEC Platforms Otsuki Office
Address: 747 Maki, Otsuki-cho, Otsuki City
The Otsuki Plant mainly produces optical submarine equipment (optical submarine repeaters, optical submarine branching equipment) and optical communication equipment (optical components), which are indispensable for the globalizing information network society. We support society through manufacturing in a clean manufacturing environment, making full use of high-precision optical component manufacturing technology and the equipment and know-how to manufacture highly reliable products that can withstand long-term use of 25 years on the ocean floor.
