An international research team has investigated how solar could be combined with thermoelectric coolers (TECs), which are small solid-state heat pumps used either for heating or for cooling. A system was built with six solar panels, an air duct system, four batteries, a charge controller, TECs, an inverter, heat sinks, a test chamber, and condenser fans.

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.

A British-Egyptian research group has tested the use of hydrogels beads for PV module cooling. The micro-sized particles were saturated with aluminium oxide (Al2O3) water-based nanofluids and placed below the simulated PV panels. The experiment showed, according to the scientists, that the hydrogels beads were able to significantly reduce the temperature by between 17.9 and 16.3 degrees Celsius.

Large swaths of low-cost land: check. Lots of sun and wind: check. The ability to transport green hydrogen cost-effectively to energy importing economies: check. Then you’re in the race to become one of the “renewable energy superpowers” of the low-carbon economy. A growing number of countries are assessing their renewable resources and natural attributes and positioning themselves to become green hydrogen exporters. However, not all are created equal.

University of New South Wales researchers have published research disproving claims that the energy transition to large-scale wind and solar would hinder the global economy. The research, which ousts outdated and cherry-picked data while showing the economically salutary effects of renewables, comes as 500 UNSW staff face the axe due to the impact of Covid-19.

Scientists in Morocco have designed a new bifacial module with a cooling system, based on bifacial parabolic solar cells that are connected to each other via tubes for panel cooling. They are now patenting the tech, but have yet to manufacture an initial prototype.

As pv magazine has learnt, the Saudi energy giant lowered its offer to $0.02752/kWh at the last minute, beating the bid lodged by Spain’s Fotowatio, which offered $0.02791 per kWh.

The lowest bid was submitted by Spanish developer Fotowatio, which offered US$0.02791 per kWh. Slightly higher, at $0.02799 per kWh, was the offer of Saudi power company, ACWA.
