Volvo Buses in project researching use of second-life electric bus batteries to store solar energy

Green Car Congress

Batteries from electric bus route 55 in Gothenburg, Sweden are being used for solar energy storage in a second-life application. The reuse and recycling of batteries is a key issue as increasing numbers of cities plan transition to electrically powered transport. What we are examining here is exactly how good that potential is.

Vattenfall, BMW and Bosch test second-life EV battery electricity storage in Hamburg for grid stabilization

Green Car Congress

Vattenfall, BMW and Bosch are testing the use of second-life EV batteries in a 2 MW, 2,800 kWh energy storage system in Hamburg, Germany, to keep the electricity grid stable. The electricity storage facility comprises 2,600 battery modules from more than 100 electric vehicles.

KAUST uses laser pulses to boost performance of MXene electrode

Green Car Congress

Graphite contains flat layers of carbon atoms, and during battery charging, lithium atoms are stored between these layers in a process called intercalation. With the nanodots in place, the material had a four-fold higher electrical storage capacity than the original MXene and almost reached the theoretical maximum capacity of graphite.

Hybrid biomass flow battery stores electricity and produces valuable chemicals at the same time

Green Car Congress

Rechargeable batteries store electricity in their electrode materials, while redox flow batteries use chemicals stored in tanks attached to the electrodes. Researchers have now developed a battery system based on a hybrid cell, which not only stores and provides electricity but also produces valuable chemicals in a flow system.

California Hydrogen Business Council says a robust P2G RD&D program should be a priority for the state

Green Car Congress

The case for using Power-to-Gas solutions to store renewable energy is compelling for a number of important use cases, according to a new white paper released by the California Hydrogen Business Council (CHBC). Constraining storage solutions to “electricity-in, electricity-out” only will increase the cost of intermittency.

Swedish researchers explore use of carbon fiber as active electrode in structural battery for electric vehicles

Green Car Congress

Researchers in Sweden are exploring the use of carbon fiber as an active electrode in a multifunctional structural Li-ion battery in an electric car; i.e., electrical storage is incorporated into the body of the car. This can result in a weight reduction for electric vehicles. (Photo: Peter Larsson) Click to enlarge.

U of Illinois team models capabilities of hybrid-electric propulsion systems for general aviation aircraft

Green Car Congress

Jet fuel and aviation gasoline are easy to store on an airplane. We’re harnessing only a small fraction of that energy but we currently don’t have electrical storage systems that can compete with that. They are compact and lightweight when compared to the amount of energy they provide. This project was supported by NASA Neil A.
