Forget batteries, what if surplus renewable energy could be stored as information?
A pair of researchers from UC San Diego has proposed to precompute certain data when the grid is flooded with solar or wind power, and then store it on servers for later use.
Reversible photovoltaic shade under the Madrid sky
The 8 kW photovoltaic shade was deployed on the outdoor rest area of a commercial building located in the northern part of Madrid. It was built with conventional solar modules provided by JA Solar and a structure made with light galvanized steel profiles for plasterboard partitions.
Adani Green Energy raises INR 612 crore for debt refinancing
The developer’s three arms, which collectively have 930 MW of operational solar power projects, have raised INR 612.30 crore (US$81.96 million) through their maiden domestic bond issuance. The proceeds will be utilized to part-refinance existing rupee term loan bearing higher interest cost.
India’s annual lithium battery market will reach 116 GWh in eight years
The annual demand for lithium-ion batteries in India will reach 116 GWh in FY 2029-30, with electric vehicles (EVs) accounting for 90%.
Cobalt-free, solid-state, lithium-ion battery plant opens in Silicon Valley
U.S-based solid-state battery start-up Sparks has opened a pilot plant for its patented lithium battery technology based on zero cobalt cathodes. The company wants to challenge China’s dominance in next-gen battery development.
Multi-level fin heat sinks for solar module cooling
Developed by Malaysian scientists, the proposed multi-level aluminum fin heat sinks (MLFHS) were found able to reduce the module operating temperature by up to 8.45 degrees Celsius and increase power yield by up to 10.75%. The system cost was estimated at $0.60/W.
Scatec and Acme put their 900 MW Rajasthan solar project on hold
Norway’s Scatec, which has a 50% stake in Acme’s 900 MW solar project in Rajasthan, cited a lack of domestic solar panel supply and the 40% import duty on solar panels effective from April as the reasons for putting the PV project on hold.
Rajasthan to create geo mapping-based data bank for renewable energy projects
The move is aimed at identifying chunks of land for solar plants and solar parks as the State government looks into the possibility of developing more capacity in the state and further increasing its ‘37.5 GW by 2024-25’ renewable energy generation target.
Tata Power to deploy electric vehicle charging stations at Apollo Tyres retail outlets
Tata Power has signed the deal to set up electric vehicle (EV) charging stations at Apollo Tyres’ 150 branded retail outlets. In addition to the customers visiting these tyre retail outlets, the charging stations would be open for use by the general public as well.
Perovskite solar cell with record-breaking fill factor of 86.6%
An international group of researchers has achieved the highest fill factor reported for perovskite cells of any size to date. The device was fabricated with a nitrogen-doped titanium oxide (TiOxNy) electron transport layer aimed at improving charge transport between the cell’s perovskite absorber and the electrodes.
