Cost comparison between lithium batteries, fuel cells, reversible solid oxide cells as storage for off-grid rooftop PV

Scientists in the United Arab Emirates have looked at how off-grid rooftop PV could be combined with batteries, fuel cells or reversible solid oxide cells for energy storage. The modelling assumed a typical commercial building in Los Angeles.

Australians come on board for 25GW green hydrogen project

Australian engineering company Worley will help develop a $39 billion green hydrogen project in Oman.

Fully PV-driven system to produce water, electricity, crops

Researchers in Saudi Arabia have fabricated an integrated fully PV-powered system to extract fresh water from the atmosphere. The system uses excess heat from the solar modules to evaporate and condense water that can then be used to grow crops. Part of the water is also used to cool down the solar modules through an active cooling technique.

Singapore secures stake in Australian green hydrogen projects

Singapore’s trillion-dollar sovereign wealth fund GIC has made a “strategic” investment in renewables developer InterContinental Energy, one of the major players behind mega solar and wind-powered green hydrogen projects planned for Western Australia’s Pilbara and southeast regions.

Green hydrogen could disrupt global trade, bilateral energy relations

While there are still many uncertainties as to the way in which hydrogen trade might evolve and change economic ties and political dynamics between countries, experts agree that green hydrogen can bring winds of change to the global energy arena. According to the International Renewable Energy Agency, significant geoeconomic and geopolitical shifts are just around the corner.

Solar for hydroponics

An international research team has examined combining solar power generation with energy-intensive hydroponic horticulture and has found that this may be a viable solution depending on project size and available incentive policies. Their approach considered various factors impacting PV system efficiency, including environmental factors, the type of solar array, and the electricity demand from the hydroponic farm.

Ever heard of synchroinverters? Grid-stabilising devices connecting renewables to distributed energy resources

A U.S.-Israeli consortium is developing synchroinverters – inverters that mimic a synchronous generator and are able to actively respond to the grid’s frequency changes while stabilising the voltage. The new devices are expected to do this simultaneously and provide grid stability services in less than 16.67 milliseconds.

Photovoltaic rotary energy system for domestic applications, high-rise buildings

Developed by scientists in Turkey, a system prototype has operated at lower PV module temperatures and removed most of the dust accumulation. The researchers are now planning to improve the device by applying maximum power point tracking (MPPT) converter topologies.

‘World’s biggest TOPCon solar plant’ begins generating

Solar manufacturer Jolywood, which supplied almost 500 MW of its bifacial tunnel oxide passivated contact panels for Oman’s Ibri II facility, has claimed the power plant is the biggest to date to deploy the high-efficiency technology.

SolarEdge posts more record numbers, says good times are set to continue rolling

The inverter and battery manufacturer said it has been sitting on a record order backlog for the current three month window and the opening quarter of the new year, which may in part be down to a long Covid shutdown at its Vietnamese production base.
