IHS Markit has released its latest Global Renewables Markets Attractiveness Rankings, based on measures related to investment confidence and ease of development, with Australia ranking in the top ten.

The federal government will provide $131 million of soft loans for a $177 million, 100 MW solar park near the Jamuna river in Bangladesh’s Jamalpur district, where a second park of a similar size is being planned by Dhaka and a Chinese partner.

Scientists in China took a closer look at the role of defects in limiting the performance of perovskite solar cells, demonstrating a screening effect that could be tuned to make material defects “invisible” to charge carriers, greatly improving cell performance. Using this approach they demonstrate a 22% efficient inverted perovskite solar cell, and theorise several new pathways to even higher performance.

Scientists investigating the aging mechanisms affecting today’s lithium-ion batteries observed that the loss of lithium over time is one of the main causes of performance loss. With this in mind, they developed and tested a “relithiation” process that promises to eliminate much of the cost and complexity from recycling battery components and materials.

First Solar and Nel Hydrogen Electrolyser AS have announced they will collaborate to develop power plant control and other supervisory systems as part of a broader plan to build integrated photovoltaic-hydrogen power plants.

The municipal government of Barcelona is supporting the development of a 50-square-meter pilot project to test the feasibility of PV-paving tech.

Australian governments are busy designing the nation’s transition to a clean energy future. Unfortunately, in a misguided effort to ensure electricity supplies remain affordable and reliable, governments are considering a move that would effectively pay Australia’s old, polluting coal-fired power stations to stay open longer.

Owners and operators of energy storage systems, as well as investors, need transparent ways to evaluate battery performance. They need certainty that the selected batteries for their ESS projects will perform reliably, have predictable life expectancies, and meet projected revenue and contractual obligations over their lifetimes. The economic viability of entire projects depend on this confidence, writes Michael Kleinberg of DNV.

New cell and module technologies are boosting power outputs, but they often have implications for quality. A focus purely on cell cracking illustrates just this point, with some approaches proving beneficial, and others potentially problematic – cue Tristan Erion-Lorico from PV Evolution Labs (PVEL).

The National Energy Administration has ordered grid companies to supply enough network connection points for all the solar and wind projects registered in 2019 and 2020, and said variable renewables should be supplying 11% of the nation’s electricity by the end of the year.
