New Siemens electric arc furnace for steel-making cuts CO2 emissions by up to 30%; Tyasa incorporating first unit in new mill

Green Car Congress

The new system, which recovers energy from the hot exhaust gas, also reduces costs by around 20%. However, the process consumes vast amounts of electricity, produces lots of carbon dioxide, and can lead to fluctuations in the stability of the power grid. The Tyasa mill is scheduled to be completed by mid-2013. Click to enlarge.

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.

NASA awards $16.5M to four teams for additional research into reducing aircraft fuel consumption, emissions and noise

Green Car Congress

NASA refers to this time period as N+3, representing technology three generations more advanced than what is in service today. Under the new contracts, the teams will now develop concepts and models that can be tested in computer simulations, laboratories and wind tunnels. NASA is awarding $16.5 million, three years.

BMW Group plants stepping up activities in balancing-power market to contribute to grid stability

Green Car Congress

This is necessary because power generation from renewable energies depends on availability of sun and wind and can therefore only be controlled to a limited extent. For this reason, network operators utilize so-called electricity balancing to ensure that the power grid remains stable, despite increasing integration of renewable energies.
