A German-Israeli research group has gathered to discuss which storage technologies may outperform lithium-ion batteries in the future. They concluded that there is no such a thing as a “post Li‐ion” era in sight. They recommended a “side‐by‐side” approach for multiple technologies in different applications, as well as the hybridization of technologies.
The tariff is around $0.0021 lower than the $0.0156/kWh French oil giant Total and Japanese conglomerate Marubeni Corp offered in Qatar’s 800 MW tender in late January. French energy company EDF and Chinese solar company JinkoPower reportedly submitted the record bid in the UAE exercise.
A U.S. research group is developing inverters and cybersecurity standards to protect solar installations from cyberattacks. The researchers said that inverters can shut down if they are hacked, or contribute to grid instability and result in the overcharging of batteries, while potentially creating problems that we still don’t know how to address.
A 120 MW solar plant located in a fishery near Cixi, in the Chinese province of Zhejiang, was recently completed. The plant, which secured a rate of $0.12/kWh, is the second phase of a 320 MW project owned by Chinese developer Hangzhou Fengling.
A U.S. research group has developed a new solar cell, based on six active photoactive layers, to capture light from a specific part of the solar spectrum. The scientists claim that they could potentially reach a 50% efficiency rate with the new cell.
GE Research plans to test new controls with its PV LV5 inverter platform — aiming to develop “grid-forming” controls to allow wind and solar inverters to form voltage and frequency levels like traditional generators. The company wants to improve coordination and synchronization among multiple grid-forming resources, and is working to improve the transient stability of systems with high renewables penetration.
Global grid-connected solar capacity reached 580.1 GW at the end of 2019, according to the International Renewable Energy Agency. Total installed renewables capacity hit a remarkable 2,563.8 GW, with hydropower remaining the dominant source at 1,310.9 GW, followed by wind at 622.7 GW.
The product costs around $28 to $30 per square-foot although prices will vary depending on project complexity. Swiss manufacturer Freesuns says its tiles can be used on historic buildings and can cover 100% of rooftops.
France’s Sunbooster has developed a technology to cool down solar modules when the ambient temperature exceeds 25 C. The solution features a set of pipes that spread a thin film of water onto the glass surface of the panels in rooftop PV systems and ground-mounted plants. The cooling systems collect the water from rainwater tanks and then recycle, filter and store it again. The company claims the technology can facilitate an annual increase in power generation of between 8% and 12%.
