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.

Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

US $5 PER KILOGRAM Cost of green hydrogen today. And the Norwegian company H2Carrier recently received approval in principle for its concept for an industrial-scale floating production unit to make green ammonia at sea. The chemical processes are generally most efficient when there’s a constant supply of power and reactants.

OSU team develops new aqueous lithium-iodine solar flow battery; 20% energy savings over Li-I batteries

Green Car Congress

This concept, the researchers notes in their paper in the Journal of the American Chemical Society , also serves as a guiding design that can be extended to other metal-redox flow battery systems. However, challenges with hydrogen storage and the cost of fuel cells make those systems complicated and difficult for implementation.

Despite this, a 2003 EPRI study , assuming only $2/gallon gas , zero buying incentives, and a PHEV premium of $3-$5,000 more than standard hybrids, shows that the total lifetime cost of ownership for a PHEV will be lower than that of any other vehicle type -- so the payback will be there. Whats Vehicle-to-Grid and why would I like it?

Sven Thesen, the communication and technology director for Better Place , a start-up that is gaining traction (see this recent New York Times article ) in its effort to create a network for electric cars in various countries, likened the concept of electric cars to cellphones. Fifteen years ago, how many people had a cellphone?”
