Baker Institute report: China has positioned itself as a gatekeeper to the energy transition; nickel case study

Green Car Congress

Widely ignored, although gaining attention, is China’s strategic positioning as a crucial gatekeeper to several key “green” technologies, including battery energy storage to support electric vehicles (EVs)—specifically, battery electric vehicles (BEVs)—along with stationary storage for power grids.

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.

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

However, few studies have used real-world rideshare trip data in their estimates, or included additional assessments of air pollution and traffic impacts, from the switch. The researchers collected simulated rides provided by three fleets: gasoline-powered, and electric-powered with either 40 kWh or 60 kWh battery packs.

Fraunhofer analysis finds battery-electric trucks have energy cost advantage over hydrogen trucks

Green Car Congress

In a recent analysis, Fraunhofer ISI concludes that battery-electric drives will become established in heavy-duty applications in the commercial vehicle sector and that fuel cells will remain a niche application. The decisive factor for the switch to battery-electric vehicles is the energy cost advantage compared to hydrogen and diesel.

LowCVP LCA study finds matching battery size with vehicle use is crucial for the environment

Green Car Congress

For electric and plug-in hybrid vehicles the carbon intensity of the power grid is also a key factor in terms of the vehicle’s full life cycle emissions. However, if a race for bigger and bigger batteries is left unchecked, EVs doing low mileages could undermine some of the potential benefits, the report finds.

PNNL study finds 2028 grid resource adequacy likely sufficient for high EV penetration; managed charging strategies can double adequacy

Green Car Congress

A new study of the impact of high EV adoption on the Western US power grid by a team from Pacific Northwest National Laboratory (PNNL) has found that 2028 grid resource adequacy—from generation through transmission—is likely to be sufficient for high EV penetration. Source: PNNL.

Japan team evaluates battery-assisted low-cost hydrogen production from solar energy

Green Car Congress

Researchers from Japan’s NIMS (National Institute for Materials Science), the University of Tokyo and Hiroshima University have jointly conducted a techno-economic analysis for hydrogen production from photovoltaic power generation (PV) utilizing a battery-assisted electrolyzer. This approximately converts to US$1.92 to US$3.00/kg
