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.

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.

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.

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.

Israel-based Augwind has built its first 250 kW/1 MWh compressed air storage system for the collective community of Yahel, in the southern, desert part of the country. The commercial scale facility will be connected to a PV system and will be used for behind-the-meter services.

Fotowatio Renewable Ventures’ (FRV) Australian platform includes 637 MW (DC) in projects already operational or under construction, and a pipeline comprising 7 GW of solar projects and 1.3 GWh of battery storage.

Scientists have demonstrated a zinc-ion battery that overcomes many of the challenges for this technology. By working with a highly-concentrated salt solution as the electrolyte, the group was able to achieve stability over more than 2,000 cycles combined with a strong electric performance. The group says that its work opens up “a viable route to developing aqueous batteries for emerging electrochemical energy storage applications.”

The new headquarters planned by DEWA is intended to consume no more annual electricity than it generates, from a large volume of rooftop and building-integrated PV.
