Two solar firms have helped launch an industry group promoting green hydrogen, which is produced using solar or wind power. The group backs a Utah project that would use 30% green hydrogen in 2025 and 100% green hydrogen by 2045.
Florida led the region for small-scale installations, while Maryland kept the lead on a per-capita basis. Solar advocates look to improve opportunities for distributed solar throughout the region in 2020.
To help safeguard residents’ health and comfort during an extended power outage, a new program will provide loan guarantees for solar+storage installations that could keep cooling systems, medical equipment and refrigerators running.
To integrate an increasing percentage of renewables, Hawaiian Electric has turned to a standard solar+storage framework, matching all new solar capacity with an equal capacity of storage with four-hour duration.
With tortoise-sized openings at the bottom of the fence, and improved growth of plants vital to tortoise survival, a solar farm in Nevada can provide better habitat than the surrounding desert. First Solar found similar habitat gains in California.
Stanford researchers have a plan that would balance 2,000 GW of solar capacity and 2,300 GW of wind power with 3,300 GW of battery capacity and a large amount of flexible load. Consumers would save 64% on total energy bills, partly from electrification of transportation and heating.
To get long-duration storage costs down to 5 cents per kilowatt-hour, research teams funded by ARPA-E are pursuing breakthroughs in flow batteries, hydrogen storage and other technologies—even thermovoltaics.
At least seven utilities chose to bias their resource modeling against solar in 2019. The good news is that transparent utility modeling could fix the problem.
Boulder sees a public utility as a way to reach 100% renewables, while San Francisco aims for 100% clean energy, and Pueblo expects 10% to 14% savings.
Deer fence installed upside down lets foxes and other small wildlife through to forage and pursue prey. Solar developers in Tennessee and North Carolina have the photos to prove it.
