Fossil fuels such as petroleum, coal, and natural gas are unevenly distributed in various regions of the globe, and energy trends are changing rapidly on a daily basis. In addition, greenhouse gases produced by the combustion of fossil fuels have a significant impact on climate change, and reducing emissions is a global challenge.
JSW Group is contributing to energy conservation and, ultimately, the reduction of greenhouse gas emissions by approaching each aspect of energy use from "making," "transporting," and "storing" to "using" energy wisely.
Lithium-ion batteries are being used as a new way to store electricity in electric vehicles (EVs) and smartphones.
The separator is a resin film inside the lithium-ion battery. Its main role is to prevent contact between the positive and negative electrodes and to manage the flow of ions between them. While ensuring sufficient ion conductivity, the separator also plays a major role in ensuring a stable power supply by blocking ion conductivity when the battery heats up.
JSW Group is engaged in manufacturing equipment for separator films, which are in increasing demand for use in lithium-ion batteries. JSW Group boasts a high market share both in Japan and overseas, and is involved in the further spread of lithium-ion batteries.
Hydrogen has the advantages of "not emitting carbon dioxide when burned" and "being able to be produced from a variety of resources," and is attracting significant attention as an alternative energy source.
However, the development of infrastructure for production, transportation, and storage is essential for a stable supply of hydrogen energy. Hydrogen stations, which supply hydrogen to fuel cell vehicles, are being developed, but it is said that it will take some time before they are widely used throughout Japan.
To promote the spread of hydrogen energy, JSW Group is developing and supplying hydrogen storage facilities. The steel pressure accumulator for hydrogen stations (HyST300) offers the world's highest level of durability at a low cost. The HyST300 is being installed at hydrogen stations throughout Japan.
Hydrogen Storage Alloy Tanks" are offered for a wide range of applications, from small portable tanks to large stationary tanks and operation systems, taking advantage of the features of hydrogen storage alloys (MH), which are compact and can store a large volume of hydrogen.
A flywheel energy storage system is a system that converts and stores kinetic energy as rotational energy.
Electric energy is converted and stored as kinetic energy by using electrical energy to rotate the disks in the device. When electrical energy is needed to be extracted from the storage device, the main mechanism is to obtain electrical energy from the rotational motion. This system can be charged and discharged faster than lithium-ion batteries, and has a longer service life.
Flywheel energy storage systems are used in combination with natural energy power generation systems that use wind and solar power to equalize the supply of electric power, etc. JSW Group promotes the use of renewable energy and other forms of electric power by providing components for flywheel energy storage systems.
JSW Group provides a wide range of manufacturing and processing equipment for plastics.
In particular, we were the first in the world to switch from hydraulic to electric power for injection molding machines used to mold plastic products, helping to reduce energy consumption during the manufacturing stage. We are also actively working to improve the energy efficiency, space efficiency, weight reduction, and productivity of various manufacturing and molding equipment.
All companies are now required to reduce their environmental impact and respond to climate change issues. Energy conservation in the manufacturing process is no exception.
Improving productivity and reducing losses in the manufacturing process are also linked to energy conservation and reduction of environmental impact. The IoT solution "J-WiSe®" we have developed for injection molding machines has four pillars (production management, service and maintenance, operation support, and production automation system) to make the production process smarter.By making the manufacturing process smarter, we contribute to energy conservation throughout production.
Regenerative energy is energy obtained by using the kinetic energy of an object moved by electric power to generate electricity again. For example, a train uses electric power when it runs, but when it brakes, the kinetic energy generated by the wheels is used to generate power and regenerative energy is obtained.
JSW Group has developed a mechanism to use regenerative energy in the operation of electric injection molding machines used to manufacture metal and plastic products. At the same time, the power consumption of the molding machine itself has been reduced, resulting in lower power consumption than before. We provide injection molding machine systems that use energy wisely.
Power semiconductors are semiconductors used in industrial equipment, EVs, and other situations where high voltages and large currents are involved. In the midst of efforts to reduce energy consumption, power semiconductors are also required to achieve further power savings.
Gallium nitride (GaN) is attracting attention as a material for power semiconductors that can replace conventional silicon (Si).
JSW Group is involved in the mass production of gallium nitride crystals, a new generation semiconductor material, using a technology for crystallizing synthetic quartz crystals under high temperature and high pressure.
