PV plants lasting longer, with lower operational costs

Solar plants are now expected to last 32.5 years and cost $17 per kW/year to operate, as shown by a Berkeley Lab survey of industry participants.

Assessing the soiling mitigation properties of anti-reflective coatings

Researchers in China have sought to understand how soiling exacerbated by anti-reflective coatings might inhibit solar panel output. In terms of effectiveness against soiling, the scientists found hollow-silica-nanoparticle coatings did better than solid silica alternatives.

Israel wants another 15 GW of solar by 2030

Energy minister Yuval Steinitz has announced the country’s 2030 renewable energy target will rise to 30%, with solar expected to account for the lion’s share. Approximately $23 billion more clean energy investment is envisaged this decade.

Chinese PV Industry Brief: Jinko’s new capacity and a 200 MW solar park

JinkoSolar has begun construction of a new 16 GW module production base in Yiwu city, Zhejiang province and Eging PV has resumed a 200 MW solar project in Qitai county in the Xinjiang Uygur Autonomous Region, after securing approval from local authorities. The China National Energy Administration has confirmed the nation can add no more than 48.45 GW of solar to the grid this year.

Siemens and Engie plan 12 MW green hydrogen and gas project in France

A €15.2 million power-to-X-to-power hydrogen storage facility is being planned in Saillat-sur-Vienne, in Nouvelle-Aquitaine. The project partners want to use renewable energy from the grid and water to produce and store electrolyzed hydrogen. It would then be mixed with natural gas to power an upgraded, 12 MW Siemens SGT-400 industrial gas turbine which previously generated steam for local manufacturing and would be able to return power to the grid to meet demand.

Electric aircraft engines could take to the skies over Australia

Zero-emission, low-cost regional flights with just eight other sanitized folk and a disinfected pilot! Yes, Covid-19 is warping our view of the future but the successful electrically-powered maiden flight of a Cessna Caravan last week offers the potential for new modes of transport to support a wider economic recovery in Australia.
