Kyoto-based Rohm Semiconductor and Taipei-based Delta Electronics are both benchmarks in the application of renewable energy. It is a common goal of the world that net-zero emissions will be achieved by 2050, and Kazuhide Ino, managing executive director of Rohm, calls for upstream and downstream cooperation to address such issues.
Generally speaking, before 2030, quality companies 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 innovative technologies and international cooperation. We must understand that today's energy saving and carbon reduction are creating only "pressure," but after 2030, the pressure will become the cost of enterprises, and even risk.
Rohm has a SiC plant in Fukuoka to meet the market demand. This plant is currently a 6-inch fab, but is expected to be moving toward 8-inch production. GaN components will also be available from 2022. Rohm of course understands that semiconductor manufacturing consumes a lot of electicity. For the plant, it has als build its own PV power facility, and purchase renewable energy to support its needs.
The power used in the Fukuoka fab could be 100% from renewable energy. The entire Rohm Group used 100,000MWh of renewable energy in 2021, which was lower than Delta's 310,000 MWh. But Rohm is already using 100% green energy at its building near the Kyoto Station and at its new Yokohama building, and will join the International Climate Initiative as a member of the RE 100 in 2022.
According to IEA estimates, new installations for wind and solar energy amount to about 1,020GW per year. The energy storage system with high efficiency and good response speed will definitely be one of the important solutions. With such developments, the energy structures and grid systems will change. One-way electricity transmission will be replaced by multiple-way and diversed systems. Energy will be the major challenge, and high-efficiency storga systems will be one of the major soultions.
Delta has long made the development of solar and wind energy inverters a priority. There are energy management solutions such as high-efficiency conversion and high-efficiency energy control solutions. Delta is committed to improving energy use, with collaboration with upstream semiconductor companies.
