PNNL team develops electrolyte for high-voltage sodium-ion battery with extended longevity

Green Car Congress

Cheap and abundant, sodium is a promising candidate for new battery technology. However, the limited performance of sodium-ion batteries has hindered large-scale application. Sodium-ion batteries (NIBs) have attracted worldwide attention for next-generation energy storage systems. A paper on the work appears in Nature Energy.

Expanded graphite as a superior anode for sodium-ion batteries

Green Car Congress

Researchers at the University of Maryland, with colleagues at the University of Illinois at Chicago, report on a new method for expanding graphite for use as a superior anode for sodium-ion batteries in a paper in Nature Communications. Sodium (Na) is an earth-abundant and inexpensive element, and shares many properties with lithium.

Ceramatec licensing molten sodium technology for heavy oil upgrading; removing the need for diluent for bitumen

Green Car Congress

Flowchart of Molten Sodium Upgrading process. A new company, Field Upgrading (Calgary, Alberta), has been formed dedicated to developing and commercializing the Molten Sodium Upgrading (MSU) technology. When electricity is applied to the ceramic membrane, elemental sodium is extracted through the membrane and recycled to the process.

Polymer microcapsules with liquid carbonate cores and silicone shells offer a new approach to carbon capture

Green Car Congress

A multi-institution team of researchers has developed a novel class of materials that enable a safer, cheaper, and more energy-efficient process for removing greenhouse gas from power plant emissions. They have significant performance advantages over the carbon-absorbing materials used in current CCS technology. —Vericella et al.

EPA opens door to consider Carbon Capture and Utilization as part of new Clean Power Plan; algae industry locks on

Green Car Congress

EPA’s newly released voluminous final Clean Power Plan rule ( earlier post ) has established the first national standards to limit CO 2 emissions from fossil-fuel-fired power plants (Electric Generating Units, EGUs), with a target of a 32% reduction against a 2005 baseline by 2030. The actual text of the CPP rule is, however, more reserved.
