3.3 GW renewables pipeline provides cover for coal-fired power plant closures in Australia

Record investment in solar and wind farms across the National Electricity Market has helped to quell concerns that Victoria and South Australia will face increased risk of blackouts later this decade following the impending closure of the Yallourn coal-fired power plant.

Indian state tenders 500 MW of solar capacity under farming support scheme

With the national KUSUM program offering farmers the chance to develop projects or lease their land, developers in Odisha will have until June 22 to bid for projects. The state utility will buy the power generated under a 25-year PPA for a maximum INR3.08/kWh ($0.04).

Best membrane for non-aqueous redox flow batteries

A Chinese-Finnish research team has identified composite membranes as the best future option for non-aqueous redox flow batteries.

Another 2 GW of solar under review in Chile

The Chilean environmental authorities are currently scrutinizing the projects Solar La Pampina (160 MW), Gabriela (220 MW), Ghungnam Kcs (709 MW of PV and 300 MW of CSP), Pelequén (175 MWp), and Planta Solar Sol del Loa (640 MW).

Air-assisted water spray for PV module cooling

Turkish researchers have developed a cooling technique in which water is sprayed via an air-assisted external mixing flat fan nozzle. The system can produce smaller droplet sizes to ensure the even distribution of water on panels.

Future of cadmium telluride PV tech

In the third interview of a series, pv magazine spoke to Prof. Arvind Shah of École polytechnique fédérale de Lausanne and Associate Prof. Alessandro Romeo from the University of Verona about the challenges and opportunities of cadmium telluride (CdTe) PV tech. They said there is still potential to ramp up efficiency and cut costs, and claimed that the toxicity of cadmium should not be seen as a serious concern.

Micro III-V solar cell with 33.8% efficiency

Developed by a French-Canadian research group, the triple-junction cell is based on indium gallium phosphide (InGaP), indium gallium arsenide (InGaAs) and germanium (Ge) and has an active area of only 0.089 mm2. It can be used for applications in micro-concentrator photovoltaics (CPV).


Enapter develops MW-sized AEM electrolyzer

The new electrolyser with anion exchange membrane technology is expected to produce 450 kilograms per day and will be available on the market in 2022.

Rooftop CPV-thermal tech to produce electricity and freshwater

It’s claimed the decentralized desalination system can deliver a levelized cost for desalinated water of US$0.7-4.3/m3, depending on PV costs and electricity prices. It was built with several concentrated photovoltaic/thermal (CPV-T) collectors, a hot water tank, a V-MEMD module, a seawater feed tank, and a distillate tank.

Dealing with solar park visibility

Dutch researchers have studied how solar parks can be blended into the landscape across 11 “frontrunner” sites in Europe. They considered visual impact, land availability, and end-of-life issues.
