Sandia innovation eliminates reliance on rare-earth magnets for large-scale wind turbines

Green Car Congress

Motivated by the need to eliminate expensive rare-earth magnets in utility-scale direct-drive wind turbines, Sandia National Laboratories researchers have developed a fundamentally new type of rotary electrical contact. I started thinking that maybe not every conceivable rotary electrical contact architecture has been thought of yet.

EIA: natural gas-fired reciprocating engines are being deployed more to balance renewables

Green Car Congress

Source: US Energy Information Administration, Preliminary Monthly Electric Generator Inventory, January 2019. Reciprocating engines tend to be smaller than other types of natural gas-fired electricity generators and account for a relatively small share of power plants fueled by natural gas.

Bloomberg NEF forecasts falling battery prices enabling surge in wind and solar to 50% of global generation by 2050

Green Car Congress

This year’s outlook is the first to highlight the significant impact that falling battery costs will have on the electricity mix over the coming decades. BNEF predicts that lithium-ion battery prices, already down by nearly 80% per megawatt-hour since 2010, will continue to tumble as electric vehicle manufacturing builds up through the 2020s.

Vattenfall contracts with BMW for up to 1,000 new 33 kWh Li-ion batteries this year for storage projects in wind farms

Green Car Congress

The first energy storage from the BMW-i3 batteries is being built at the 122 MW onshore wind farm “Princess Alexia” near Amsterdam. It is meant to maintain the security of supply with a feed-in of 100% renewable energy. Other possible applications would be electricity storage in private households. With a capacity of 3.2

MIT researchers propose subsea version of pumped hydro for renewable energy storage

Green Car Congress

Researchers at MIT are proposing using a variation on pumped hydroelectric systems for storage of electricity produced by offshore wind farms. The key to this Ocean Renewable Energy Storage (ORES) system is the placement of 30-meter-diameter hollow concrete spheres on the seafloor under the wind turbines. Earlier post.).

Norwegian startup Blastr plans €4B green steel plant in Finland

Green Car Congress

The area has excellent conditions for industrial activities: a deep-water harbor and an excellent electricity transmission network. Green steel will be a critical raw material for developing renewable energy infrastructure, such as wind turbines, as well as in segments such as construction, the automotive industry, and consumer goods.
