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.
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.’

Scaling clean energy by and for Black farmers in Florida
In one Florida town, NREL researchers worked with local stakeholders and community members to develop a guide for installing solar panels on churches and other commercial-scale buildings across the state.
To achieve net zero energy status, solar-powered buildings should not exceed 10 floors
Researchers in Canada have found that nearly zero-energy buildings (NZEBs) with on-site solar energy generation should not exceed an energy use intensity (EUI) of 50 kWh/m2a, which they said corresponds to a maximum of 10 floors. They also ascertained that the maximum permitted EUI by net-zero energy status is 17 to 28 kWh/m2a.
