US based battery company Solid Power announced that it has received $130 million in new funding from investors including Ford and BMW. With this backing, the company plans to begin pilot scale production of solid-state lithium-ion batteries suitable for electric vehicles early next year.

The iron and steel sector is the ‘world’s largest industrial source of climate pollution.’ This steel mill in Pueblo, Colorado, will be the first in North America to rely on solar power.

Getting the most out of a bifacial module requires a rethink at almost every level of system design and the industry is hungry for field data generated by such systems to better inform energy yield modeling and define the best approaches to maximizing yield at minimal cost. In May, the U.S. National Renewable Energy Laboratory began a three-year study into bifacial performance which is beginning to yield results.

By tweaking the chemical composition of the material to create a ‘triple’ perovskite, scientists at the U.S. National Renewable Energy Laboratory say they have overcome one of the technology’s inherent stability issues and fabricated a perovskite cell which achieved 27% efficiency in a tandem format with a silicon device.

A report published by the Rocky Mountain Institute makes recommendations for rooftop PV in regions affected by high winds. The study draws on the knowledge of structural engineers asked to analyze 25 solar systems across five Caribbean islands after they were hit by major hurricanes in 2017 and last year.

Black Hills Energy is seeking 200 MW of solar power or wind plus energy storage capacity as part of a request for proposal, driven by summer 2019 bids for solar+storage of $0.024/kWh and $0.036/kWh and looming cuts to the 30% investment tax credit.

Researchers in the U.S. claim to have developed a manufacturing process based on the use of a latex balloon that could lead to the production of more efficient curved electronic devices, including hemispherical solar cells.

An International Energy Agency report estimates the share of nuclear power in advanced economies could fall by two-thirds by 2040, as aging plants retire. The report claims without support for nuclear, the transition to a low carbon energy system would be far more complex and threaten global emissions targets.

While U.S. senators Ed Markey and Alexandria Ocasio-Cortez introduce a resolution for a clean energy package, legislation has been tabled in six states aiming to implement 80-100% clean energy by 2050 or earlier.

Xcel Energy’s 120-day report to Colorado regulators includes an additional 1.1 GW of wind at 1.1-1.8¢/kWh. Solar power bids have come in at 2.2-2.7¢/kWh, and solar+storage at 3.0-3.2¢/kWh.
