Sunrise brief: FERC reforms interconnection, speeding critical renewables delays 


People on the move: ConnectDER, American Clean Power and more  Job moves in solar, storage, cleantech, utilities and energy transition finance.

SolarEdge stock trades down despite record revenue in Q2  The company had strong performance in European residential and commercial markets, whereas the U.S. residential solar market wavered in Q2.

FERC reforms interconnection, speeding critical renewables delays  Over 2,000 GW of generation and storage were trapped in interconnection queues. Wait times averaged five years. FERC introduced numerous reforms that will help mend this problem.

Sunnova to participate in battery emergency program in Puerto Rico  Distributed solar and storage customers sign up with Sunnova to participate in the Flex Power Program. By compensating customers for the power supplied by their batteries, they are incentivized to participate in the program designed to provide energy that reduces strain on the grid and minimizes blackouts at critical times.

New technique to recover lead in end-of-life solar panels  A research group at Arizona State has developed a process to recover lead in its metallic form so that it can be reused in the PV industry. The process relies on a leaching solution based on a combination of acetic acid (CH3COOH) and hydrogen peroxide (H2O2), which the researchers said leaches the lead ‘in a matter of minutes.’

Carbon-cement supercapacitors for bulk energy storage  The Massachusetts Institute of Technology (MIT) has developed a scalable bulk energy storage solution with chemical with inexpensive, abundant precursors: cement, water, and carbon black. Their supercapacitors have high storage capacity, high-rate charge-discharge capabilities, and structural strength.

Cracked cathodes not all bad, battery scientists find  Scientists developed an innovative method to observe the inner workings of lithium-ion batteries and found that cracks which form in the electrode, something manufacturers do their best to minimize, may actually have benefits in allowing for faster charging.

First commercial gravity-based energy storage tower begins commissioning  Energy Vault has begun commissioning a 25 MW / 100 MWh energy storage tower adjacent to a wind power facility outside of Shanghai.
