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.

Renault makes public its lifecycle study of Fluence ICE vs Fluence EV

Green Car Congress

Emission standard. water, and non-renewable energies (crude oil, coal.) Quantifies the quantity of energy (crude oil, coal.) Further, due to the variation in the power grid mix from one country to another, the benefits of the EV varies significantly based on that grid mix. Renault Fluence Models.

Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

Then, as now, wind farms are operating off the world’s coasts—but not all of these offshore sites are connected to the mainland via underwater power cables. Almost all hydrogen produced today is designated as brown, black, or gray, meaning it was generated by burning natural gas or coal. This is called black-start capability.

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

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. To compensate for the increased amounts of these inherently–variable sources of electricity, the power grid requires additional flexibility to manage fluctuations in generation.

Lean Software, Power Electronics, and the Return of Optical Storage

Cars That Think

But some of these things are going to have to be mandated through standards and regulations, and specifically through the lens of these cybersecurity requirements and knowing what’s going into your software. I think maybe because the cover was a car perched at the top of a giant mountain of coal. I speak good. You hire wise.—But
