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.

CESifo: EVs not the best option for reduction in on-road CO2 in Germany given power mix

Green Car Congress

They report that even with today’s technology, total emissions from a combustion engine powered by natural gas are already almost one-third lower than those of a diesel engine. —Professor Buchal. This being the case, the German federal government should treat all technologies equally and promote hydrogen and methane solutions as well.

New lithium polysulfide flow battery for large-scale energy storage

Green Car Congress

The work is some of the earliest supported by the DOE’s new Joint Center for Energy Storage Research battery hub (JCESR). For solar and wind power to be used in a significant way, we need a battery made of economical materials that are easy to scale and still efficient. Batteries Power Generation Smart Grid'

Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

Using a new metric—“Energy Stored on Invested, ESOI”—they concluded that batteries were the worst performers, while compressed air energy storage (CAES) performed the best, followed by pumped hydro storage (PHS). Their results are published in the RSC journal Energy & Environmental Science. —Charles Barnhart. Energy Environ.

Australia Goes All-in on Green Hydrogen

Cars That Think

The carbon-free rigs will pack 50 kilos of hydrogen zapped from water using electricity from the refinery’s dedicated solar power plant. Resource-poor Asian neighbors such as Japan and Korea are also counting on Aussie green hydrogen to help get them off fossil fuels in the decades ahead. Why a hydrogen truck?

New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Short-term transients, including those related to wind and solar sources, present challenges to the electrical grid. Stationary energy storage systems that can operate for many cycles, at high power, with high round-trip energy efficiency, and at low cost are required. C, two-thirds of its maximum discharge capacity is observed.
