Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

AQDSH 2 refers to the reduced form of AQDS. Quinones are naturally abundant, inexpensive, small organic molecules, and similar to molecules that store energy in plants and animals. Flow batteries store energy in chemical fluids contained in external tanks, as with fuel cells, instead of within the battery container itself.

“Project Volt Gas Volt” proposes long-term financing plan to support widespread implementation of power-to-gas systems

Green Car Congress

Project Volt Gas Volt is based on a long-term financing plan and the use of existing technologies for the large-scale conversion of surplus renewable electricity to methane, with subsequent reuse. The concept is the same embodied in Audi’s e-gas project ( earlier post ), to which the VGV proposal makes continued reference.

Study suggests energy and GHG impacts of synthetic hydrocarbon fuels from CO2 are greater than impacts of existing hydrocarbon fuels

Green Car Congress

In the study, the team called fuels produced by the conversion of CO 2 into liquid hydrocarbon fuels using proven technologies “synthetic fuels”, and fuels produced via a production route that uses solar energy “solar fuels”. R indicates reference alternatives not explicitly modeled in this study. —van der Giesen et al.

New composite reduces rare earth element usage in three-way catalytic converters

Green Car Congress

Ce is an essential element in oxygen-storage materials that reversibly stores and releases large amounts of oxygen depending upon the partial oxygen pressure in the gas phase. If the A/F value is suboptimal, the conversion of noxious pollutants (NO x , CO and hydrocarbons) over the precious metal catalysts (Pt, Rh and/or Pd) is incomplete.
