Hawaii study finds vehicle-to-grid discharge detrimental to EV batteries

Green Car Congress

Results of a study by a team at the Hawaii Natural Energy Institute, SOEST, University of Hawaii at Manoa, suggest that the additional cycling to discharge vehicle batteries to the power grid in a vehicle-to-grid (V2G) scenario, even at constant power, is detrimental to EV battery cell performance. —Dubarry et al.

US DOE Awards $37 Million for Marine and Hydrokinetic Energy Technology Development

Green Car Congress

Ocean waves, tides, currents, thermal gradients, and free-flowing rivers represent a promising energy source located close to centers of electricity demand. The numerical model will greatly reduce deployment risk and add to design surety for floating ocean thermal conversion platforms. DOE Funding: $600,000. Total Project Value: $1,000,000.
