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. The technology could fundamentally transform the way electricity is stored on the grid, making power from renewable energy sources such as wind and sun far more economical and reliable. You could theoretically put this on any node on the grid. Cell schematic. Huskinson et al.

U of I study: synthetic fuels via CO2 conversion and FT not currently economically & environmentally competitive

Green Car Congress

However, they noted, that with the right combination of high FT fuel yield and low electricity and hydrogen price, the synthetic fuel system could produce fuels at a cost range similar to the reference year 2014 petroleum-based fuel prices.

WEC report: EVs need 16% market share by 2020 for fuel economy standards to be met

Green Car Congress

The World Energy Perspective 2016: E-mobility: closing the emissions gap report, published by the Council in collaboration with Accenture Strategy, examines the growth in sales of EVs as the latest technologies to increase average fuel efficiency and meet these stringent economy standards, set in all three markets, referred to as the “EV gap”.

CMU researchers find controlled charging of PHEVs can cut cost of integration into electricity system by 54-73%; higher benefits with wind power

Green Car Congress

To compensate for the increased amounts of these inherently–variable sources of electricity, the power grid requires additional flexibility to manage fluctuations in generation. But allowing grid operators to control electric vehicle charging speed could reduce these costs further. —Allison Weis. 2013.10.017.

How to Prevent Blackouts by Packetizing the Power Grid

Cars That Think

That need for balance is true of electric power grids, too. Second, conventional coal and nuclear plants are being retired for economic and policy reasons, removing stable sources from the grid. Packetized energy management (PEM) allows the power grid to flexibly handle a varying supply of renewable energy. Here’s how.

Berkeley Lab researchers develop Bchain protocol to make blockchain more robust

Green Car Congress

A paper describing the basics of BChain was published in 2014 the Proceedings of the 18 th International Conference on Principles of Distributed Systems. Because all servers running the protocol must agree on the order of commands, this protocol is often referred to as a “consensus protocol,” and it generally comes in two forms.
