Taiwanese and Japanese companies (3): Application of renewable energies

Kyoto-based Rohm Semiconductor and Taipei-based Delta Electronics are both leaders in the application of renewable energy. It is a common goal of the world to achieve net emissions by 2050, and Kazuhide Ino, Rohm’s chief executive officer, calls for upstream and downstream cooperation to address these issues.

Generally speaking, before 2030, quality enterprises will actively deploy existing technologies to save energy and reduce carbon emissions, while between 2030 and 2050, they will have to demonstrate sufficient conditions and achievements in technologies. innovation and international cooperation. We must understand that saving energy and reducing carbon emissions today only creates “pressure”, but after 2030 the pressure will become the cost of business, even the risk.

Rohm has a SiC plant in Fukuoka to meet market demand. This plant is currently a 6-inch manufacturing facility, but is expected to move into 8-inch production. GaN components will also be available from 2022. Rohm of course understands that manufacturing semiconductors consumes a lot of electricity. For the factory, she also built her own photovoltaic power plant and purchased renewable energy to support her needs.

The electricity used in the Fukuoka plant could come from 100% renewable energy. The entire Rohm Group used 100,000 MWh of renewable energy in 2021, which was less than Delta’s 310,000 MWh. But Rohm already uses 100% green energy in its building near Kyoto Station and in its new building in Yokohama, and will join the International Climate Initiative as an RE 100 member in 2022.

According to IEA estimates, new wind and solar energy installations amount to approximately 1,020 GW per year. The energy storage system with high efficiency and good response speed will definitely be one of the important solutions. With such developments, energy structures and grid systems will change. Unidirectional electric transmission will be replaced by multidirectional and diversified systems. Energy will be the main challenge and high-efficiency storage systems will be one of the main solutions.

Delta has long made the development of solar and wind inverters a priority. There are energy management solutions such as high efficiency conversion solutions and high efficiency energy control solutions. Delta is committed to improving energy use, working with upstream semiconductor companies.
