A new battery mix to prevent dendrites

Scientists at the United States Pacific Northwest National Laboratory have discovered a root cause of dendrite formation, which can cause battery failure and even fires in lithium-ion technology. With this new knowledge, the group is now working on electrolyte recipes that eliminate dendrite growth entirely.

Proposals invited for transnational projects on energy storage solutions

The aim is development of sustainable, integrated solutions for both short- and long-term storage. November 12 is the last date for submitting expressions of interest. Projects are expected to start before December 15, 2020.

CSIR-CMERI develops solar artifacts

The aesthetically appealing 1 KWp, 3 KWp and 5 KWp artifacts can be installed at public places like beaches and parks to provide electrical power for different loads.

Danish researchers bring some color to rooftop PV

Scientists led by the Technical University of Denmark have begun a project to design solar cells that can be produced in different colors with minimal effect on performance, making them suitable for building-integrated and other applications with aesthetic considerations.

Four off-grid clean energy projects chosen for India-US joint funding

A total of 168 expressions of interest were received by the Ministry of New and Renewable Energy in the second round of PACEsetter Fund programme. Out of these, projects by the Society for Economic and Social Studies, Customized Energy Solutions India, The Energy & Resources Institute and Raghavendra Suntech Systems were chosen for the award of grants.

Solar irrigation product converts sunlight directly into motion

The invention converts energy produced by PV cells directly into mechanical motion without batteries or power electronics. Its developers claim the solar motor can drive irrigation water pumps and ventilation turbines for more than 20 years without maintenance.
