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 United States is not building enough transmission lines to connect regional power networks. The deficit is driving up electricity prices, reducing grid reliability, and hobbling renewable energy deployment. grids demands public scrutiny and accountability. Their grip over the backbone of U.S.

EU Innovation Fund grants €108M to RWE’s waste-to-hydrogen project FUREC

Green Car Congress

As part of the FUREC project, RWE plans to build a pre-treatment plant in Zevenellen, Limburg, to convert non-recyclable municipal solid waste (MSW) into solid recovered fuel pellets. For comparison: This is equivalent to the output of a 700-megawatt offshore wind farm with coupled electrolyzers. textiles, paper).

New PNNL zinc-polyiodide redox flow battery offers 2x energy density of next-best system; potential for mobile applications

Green Car Congress

Researchers at Pacific Northwest National Laboratory (PNNL) have developed a new zinc-polyiodide redox flow battery offering more than two times the energy density of the next-best flow battery used to store renewable energy and support the power grid. Hoses were connected between the vials, a pump and a small stack. Source: Li et al.

Ram Promaster EV brings Detroit’s third maker into electric vans

Charged EVs

After an abortive effort to offer a third-party electric conversion of the first-generation Transit Connect, Ford hasn’t done another compact EV delivery van. Ram is importing its ProMaster EVs from Saltillo, Mexico, while Ford builds E-Transit vans at its Kansas City Assembly plant in Missouri.

Researchers call for integration of materials sustainability into battery research; the need for in situ monitoring

Green Car Congress

We need new storage technologies if more renewables are to be used on the electrical grid; similarly, the electrification of transport requires much cheaper and longer-lasting batteries. The size of these batteries (in comparison to those used for portable electronics) places severe pressure on materials resources. Resources.
