Why the Next Microgrids Will Be Well Connected

Cars That Think

The winds had barely died down when electric-power specialists and others began calling for a radical overhaul of Puerto Rico’s electricity networks, one that would emphasize renewable energy, distributed generation, and, critically, microgrids. A microgrid is like a miniaturized, tightly controlled version of a power grid.

How to Prevent Blackouts by Packetizing the Power Grid

Cars That Think

That need for balance is true of electric power grids, too. Spiking demand for electric heat collided with supply problems created by frozen natural-gas equipment and below-average wind-power production. Packetized energy management (PEM) allows the power grid to flexibly handle a varying supply of renewable energy.

Geely invests in Carbon Recycling Intl.; vehicles fueled by methanol from CO2, water and renewable energy

Green Car Congress

Its first commercial-scale production plant obtains carbon dioxide from gas emissions from a geothermal power plant and hydrogen via electrolysis of water using renewable sources of energy from the Icelandic power grid (from hydro, geothermal and wind sources). Methanol in China. Delving into the emissions side, Chen et al.

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. As one of the fastest growing electricity sources in the United States, wind can be expected to meet a large proportion of the renewable portfolio standards.

How Carmakers Are Responding to the Plug-In Hybrid Opportunity

Tony Karrer Delicious EVdriven

Expects production around 2014. The utility.will get a Ford plug-in hybrid vehicle by the end of this year and as many as 20 by some time in 2009 to test their durability, range and impact on the power grid, said Susan M. Toyota is also concerned that plug-in owners might tire of connecting their cars every day.
