Renewable Energy as the New Normal

What can technology do to help achieve a sustainable global environment? For one, it can help ensure a stable supply of electric power through the use of energy storage systems (ESS). Recent years have seen expanded use of ESS based on lithium-ion batteries, which enable more efficient charging and discharging, and allow capacity to be tailored flexibly to household equipment and other applications.

In response to the growing interest in a decarbonized society worldwide, the diffusion of renewable energy in homes is progressing, including the use of solar power generators. As a result, innovative green technology such as power storage systems are attracting attention as they enable the effective use of energy.
Residential energy storage systems (RESS) enable the storage of surplus electricity generated in homes and as an emergency energy source in times of disaster. RESS powered by TDK’s large-capacity lithium-ion batteries are characterized by a high level of safety and reliability.

To stably supply electric power, it is necessary to have equal amounts of “energy to make” and “energy to use.” However, the issue with energies of natural origin like solar and wind power is that it is difficult to control the amounts being generated. What are indispensable to overcoming this instability and making it possible to make more use of renewable energy are energy storage systems (ESS).

An ESS is system that combines large storage batteries with power controls. TDK is working to develop lithium-ion batteries for ESS use. In addition to high-capacity and high-performance lithium-ion battery packs, the unique battery management system (BMS) is distinctive to TDK’s product. This system provides for longer lifespans and better safety. In the future, by installing this ESS in a variety of locations such as the home, factories, stores, and the like, we can anticipate that they will become lifelines that supply power and support daily living even in times of disaster.

With the technology that we have cultivated to date, TDK aims to improve energy self-sufficiency and contribute to achieving carbon neutrality.


Technological development to support the effective use of energy and carbon-free society

As countries around the world aim to achieve carbon neutrality by 2050, the shift from fossil fuels to renewable energy, such as solar power, wind power, hydropower, and biomass, is a crucial challenge for the sustained development of our society. Innovative power electronics technology is being integrated into all phases of creating, storing, sending, converting, using, and sharing electricity.

Energy storage technology to supply electricity that is surplus in times of periods of high demand, such as the cutting or shifting of peak electricity demand, is vital for the diffusion of renewable energy and solution of the worldwide problem of energy demand. Research and development are progressing on large-capacity rechargeable batteries, such as lithium-ion batteries, as well as various energy storage systems using flywheels, superconductivity, and others supporting energy technologies.
