Japanese researchers have developed a new way to improve water splitting, while South Korea has completed its largest hydrogen production complex. Scotland and England have announced new hydrogen investments, and Uzbekistan and Saudi Arabia’s ACWA Power have agreed to collaborate on hydrogen projects.
Israeli researchers have developed a device that combines a reversible Si anode with halide cathodes and uses hybrid electrolytes to enable cell recharging. In the proposed system configuration, silicon is dissolved during the battery discharge process, and upon charging, elemental silicon is deposited.
The inverter and battery manufacturer says its new Sella 2 factory will produce cells for its residential solar-plus-battery products as well as for other applications.
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.
Australian engineering company Worley will help develop a $39 billion green hydrogen project in Oman.
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’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.
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.
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.
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.
