New Product
Development of “N3 N-CUBE,” Container Type Transportable Independent Power Supply
June 4, 2019New Products

Realize high mobility and quick installation, Generate and store electricity by natural energy of wind, water, and solar light

NTN Corporation (hereafter, NTN) has developed the “N3 N-CUBE,” a next-generation Container Type Transportable Independent Power Supply that can generate and supply electricity from three types of natural energy (wind, water, and solar light) in a short time by mounting power generators and storage batteries in a container. In the event of disasters, it is possible to deliver the product by multiple means (trucks, cargo ships, helicopters, etc.) to disaster areas where it has become difficult to supply electric power, and to install it quickly with a small number of people.

In recent years, large-scale disasters have occurred frequently, and it is very important to establish the system to supply electricity in an emergency and this is one of the social issues. As people are increasingly conscious of disaster prevention and mitigation, each prefecture in Japan is trying to install disaster prevention stockpile containers. However, only three containers per 10,000 people are currently installed.

The newly developed “N3 N-CUBE” not only combines natural energy products that NTN has developed*1, but also adds “transportability” to them, enabling it to be delivered, installed, and supplied easily to disaster areas where a power outage occurs. By installing the “N3 N-CUBE” in each region on a daily basis, it can quickly generate electricity in the event of disaster and recharge smartphones using USB ports and other devices, and people can use small home appliances (e.g., AC100V). As many emergency generators use cassette cylinders, gasoline, etc., they require refueling for use in a long time. However, “N3 N-CUBE” is an independent power source that utilizes natural energies and does not need fueling.

The space inside the container can be used for multiple purpose such as changing clothing room, nursing room, and break room by installing benches and desks for resting as well as shelves for storing stockpiles.

NTN promotes energy-saving through its main product of bearings, and measures to achieve sustainable growth for the next generation. The natural energy business is one the measures that NTN is taking on newly to achieve the sustainable growth. Through the natural energy business, NTN will contribute to the achievement of targets for energy and the environment of the “SDGs” (Sustainable Development Goals).
