Technology helps green development, and Denso takes multiple measures to promote"environment"strategy


In the face of global environmental challenges, Denso Co., Ltd. (hereinafter referred to as “Denso”) put forward the slogan “Create a future with smiles for the earth, society and people all over the world” in the long-term policy for 2030. Environmental protection measures promote sustainable development, and strive to achieve higher value research and development in the fields of “environment” and “safety”.

In the field of environment, with the goal of “realizing carbon neutrality by 2035”, Denso has carried out work in three areas: “creation”, “mobility products” and “energy utilization”. By reducing carbon emissions in the production process, utilizing Sustainable production technology and equipment, energy efficiency and other ways to promote the realization. For example, in order to achieve zero carbon dioxide (CO?) emissions from the factory, the Electric Development Center of Denso Anjo Works has built a verification device “CO? Recycling Facility” to recover CO? and recycle it. The verification test will be officially launched in April 2021. . In addition to recovering and reusing carbon dioxide (CO?) emitted from factories, Denso is also engaged in technology and product development in the fields of “creation” and “energy utilization”.

As a manufacturing company, environmental protection and efficiency are of great significance to the field of “creation” that carries the foundation of production. Denso has developed and used clean energy manufacturing basic products, human-machine collaborative robots that contribute to improving factory productivity, and visualized power consumption. Data software contributes to carbon reduction in the field of creation.

  DX-CELL utilizing clean energy

DX-CELL is an automation platform that can flexibly visualize data according to daily changes in the manufacturing field such as product iterations and production volumes. It has scalability and mobility to adapt to different manufacturing sites, and utilizes general-purpose robots to simplify the establishment of production lines, while flexibly changing the form of production lines when production volumes change, and also enables fuel cell production due to its specifications that can be installed with mobile batteries Direct current can be used without conversion to alternating current, which will contribute to zero-waste electricity utilization.

  COBOTTA PRO to improve productivity

COBOTTA PRO can be linked with a variety of peripheral equipment to realize the automation of difficult tasks such as assembly engineering. Efficient TCP speed*1 will also help facilitate carbon-neutral manufacturing through increased productivity, shorter runtimes and reduced power consumption.

  IoT Data share for visualization of power consumption data

IoT Data Share is a software that can connect to various devices and visualize the collected data. It supports multiple communication standards and can centrally collect factory facility data, including equipment operation information and power usage data. In addition, it can work with a variety of general-purpose data analysis applications.

exist“Energy use”In the field, Denso always pays attention to the development and application of energy efficiency and environment-friendly technologies to reduce energy waste and environmental pollution. In addition to recycling carbon dioxide (CO?), Denso has also developed SOEC (Solid Oxide Electrolysis Cell) that produces hydrogen by electrolysis of water vapor, and SOFC (Solid Oxide Fuel Cell) that extracts hydrogen from city gas as fuel for power generation.

  Carbon dioxide (CO?) recovery system

Denso’s carbon dioxide (CO?) recovery system is a small and efficient carbon dioxide (CO?) recovery device. It can also recover low-concentration carbon dioxide discharged from industrial furnaces and offices, realizing “recovery at any time where necessary.” carbon dioxide”.

  SOEC (Solid Oxide Electrolysis Cell)

SOEC is a device that produces hydrogen by electrolyzing high-temperature water vapor with ceramic electrodes. Since water electrolysis at high temperature requires less power, the power consumption is reduced by about 15% compared to electrolysis at low temperature. Denso aims to realize energy-saving design devices based on the mass production technology and knowledge of ceramic products accumulated in the manufacture of automotive parts. In addition, it is designed to connect the necessary number of units according to the amount of hydrogen used. This design is not limited by the high-pressure gas method, and it can be installed near buildings and equipment that use hydrogen, saving space.

  SOFC (Solid Oxide Fuel Cell)

SOFC is a device that uses hydrogen extracted from city gas as fuel to generate electricity. Through Denso’s unique fuel recovery technology, efficient power generation is achieved, which reduces carbon dioxide emissions by about 30% compared to using electricity provided by power companies, and reduces water and electricity costs. In addition, even in the event of a power outage, power generation can continue if the supply of fuel gas continues, so not only can the flexibility of the plant be enhanced, but it can also contribute to the local community as an electric refuge.

SOFC (Solid Oxide Fuel Cell)

DENSO is not limited to the automotive industry, but will contribute to the promotion of environmental activities in the supply chain and the promotion of global environmental protection by providing general-purpose solutions that can be expanded to other manufacturing industries and society*2.
