How Inexpensive Must Energy Storage Be for Utilities to Switch to 100 Percent Renewables?

Last week, the city of Los Angeles inked a deal for a solar-plus-storage system at a record-low price. The 400-MW Eland solar power project will be capable of storing 1,200 megawatt-hours of energy in lithium-ion batteries to meet demand at night. The project is a part of the city’s climate commitment to reach 100 percent renewable energy by 2045.

Electricity and heat production are the largest sources of greenhouse gas emissions in the world. Carbon-free electricity will be critical for keeping the average global temperature rise to within the United Nations’ target of 1.5 degrees Celsius and avoid the worst effects of climate change. As world leaders meet at the United Nations Climate Action Summit next week, boosting renewable energy and energy storage will be major priorities.

NASA builds public database on aircraft icing using 3D printing

NASA’s aeronautical researchers are using 3D printing to generate new data to deal with the aviation safety problem of icing. High-fidelity data of ice shapes generated on aircraft wings are documented through laser 3D scanning. Complex ice shapes are also 3D printed to better understand ice formation and its effects on an airplane. That data, […]
