May 2023: GS Yuasa Corporation has developed a technology that addresses several practical issues and improves energy density and extended service life. We achieved a high energy density of 400 Wh/kg with this technique, which is higher than typical lithium-ion batteries. With an energy density retention rate of over 90% after 200 cycles and a retention rate of over 85% after 300 cycles, we also confirmed that this technique could manufacture batteries with excellent charge-discharge cycle life performance.
March 2023: Johnson Controls, a world leader in smart, healthy, and sustainable buildings, has launched the new IQ Pro Hybrid Security Panel, which is specifically made for intrusion prevention in commercial buildings, large residential complexes, campuses, and K-12 sectors. The IQ Pro includes an extensive range of devices for life safety and security, supports PowerG's advanced sensor technology, and has an unmatched wireless range in the industry.
April 2023: Bosch engineering and Ligier Automotive have joined to forge a strategic cooperation to develop high-performance hydrogen engine vehicles. A demonstration vehicle based on the Ligier JS2 R is being built as part of the collaboration efforts. The hydrogen-powered Ligier JS2 RH2 will be equipped with a novel type of carbon monocoque that features three integrated hydrogen tanks, in contrast to the production model.

The Üstra power storage system, which is powered by discarded eCitaro batteries, has been put into action.
Used batteries from the Mercedes-Benz eCitaro city bus, which is an all-electric vehicle, are being given a "second life" for the very first time via this initiative. As part of the GUW+ pilot project, a stationary power storage unit that was constructed from used eCitaro batteries has been put into service at the rectifier substation of the Üstra Hannoversche Verkehrsbetriebe.
In turn, mobility is now ensured by the storage system that is located in the rectifier substation of Üstra. This system makes it possible for the electric buses offered by eCitaro and the light rail vehicles operated by the public transportation business to receive energy in simultaneously. There are 28 second-life battery systems from the Mercedes-Benz eCitaro that make up the storage system, which has a total capacity of more than 500 kWh and is known as the storage system.
The project is being pursued by the partners as a component of a pilot project entitled GUW+, which was announced in the year 2021. TU Dresden and the Fraunhofer IVI in Dresden were also members of the partnership, in addition to Alstom Transport Deutschland, which was the head of the project. Other members of the consortium were Elpro and Motion Control and Power Electronics. The company Üstra AG participated in the project as a demonstration partner, while Daimler Buses was engaged as an affiliated partner.
The second-life application was developed and implemented by Mercedes-Benz Energy GmbH, a subsidiary of Mercedes-Benz AG that specializes in the development of power storage systems.
Now, the energy storage system is being used by Üstra as a buffer for the purpose of using the recuperation energy that is created during the operation of the light rail. The stored energy makes it possible to balance load peaks and guarantee smooth ongoing operation in the event that the grid fails, as stated in a press statement that accompanies the announcement.
