New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

The new battery design could help ease integration of renewable energy into the electrical grid at lower cost, using Earth-abundant metals, according to a study just published in Energy Storage Materials. In comparison, the energy density for lithium-ion batteries used in commercial electronics and electric vehicles is around 170–250 Wh/kg.

Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%. It took us a long time to get the data needed to let us connect to the grid.

Profiteering Hampers U.S. Grid Expansion

Cars That Think

The deficit is driving up electricity prices, reducing grid reliability, and hobbling renewable energy deployment. grids demands public scrutiny and accountability. Proposed new transmission lines in the upper Midwest could connect at least 28 gigawatts of wind and solar to regional networks. Their grip over the backbone of U.S.

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

Green Car Congress

For comparison, the US DOE’s 2020 target for the levelized cost of hydrogen (production only) is $2.30/kg. The joint research team designed an integrated system capable of adjusting the amount of battery charge/discharge and the amount of electrolysis hydrogen production in relation to the amount of solar power generated. to US$3.00/kg

California agencies release report charting path to 100% clean electricity; need to triple grid capacity by 2045

Green Car Congress

Highlights from the report include the following: To reach the 2045 target while electrifying other sectors to meet the state’s economy-wide climate goals, California will need to roughly triple its current electricity grid capacity. A clean electricity grid is necessary to achieve economywide carbon neutrality.

The EV Transition Explained: Can the Grid Cope?

Cars That Think

There have been vigorous debates pro and con in the United States and elsewhere over whether electric grids can support EVs at scale. In comparison, the state’s goal is to achieve this amount by 2050. As energy expert Chris Nelder noted at a National Academy EV workshop , “vehicle-to-grid is not really a thing, at least not yet.

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.
