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.

This Clock Made Power Grids Possible

Cars That Think

As more power stations adopted the clocks, the frequency regulation allowed them to share electricity and create an interconnected power grid. But by the 1950s, clocks with improved batteries and oscillating quartz crystal resonators began to replace consumer electric clocks that synchronized with the power grid.

This article is part of our exclusive IEEE Journal Watch series in partnership with IEEE Xplore. It burns clean, generating only water as a by-product, and when it’s produced through electrolysis by splitting water into hydrogen and oxygen, the entire life cycle can be very environmentally friendly.

Gravity Batteries, Green Hydrogen, and a Thorium Reactor for China

Cars That Think

2021 was a big year for energy-related news, what with the ongoing hunt for new forms of energy storage and cleaner if not carbon-free electricity and events and research that spotlighted the weak links in our power grid. This article, by researchers at PARC and the University of Washington, is one possible answer.

Are EVs Charged Mostly By Coal Power in the US?

EV Adoption

Last year I wrote an article — Electric Vehicles Have Lower Well-to-Wheel Emissions in All 50 States and DC Than Gas-Powered Vehicles — looking at “well to wheel” from the US Department of Energy and my own analysis of EV sales and source of electricity by state. And so “EVs are bad.” of US EV sales in 2020.

Wind-to-Hydrogen Tech Goes to Sea

Chemical plants on dedicated platforms then process part of the hydrogen, combining it with nitrogen to make ammonia, or with carbon dioxide to produce substitutes for fossil fuels. The technology to produce hydrogen by electrolyzing water has been around for more than 200 years. Offshore wind parks can meet both of these criteria.
