When coupled to gigawatt-scale solar and wind generation, green hydrogen could be the clean fuel to unlock hard-to-electrify sectors of the economy. But first it must be transported cost-effectively to where it’s needed.

A global research group has developed a perovskite PV cell with titanium dioxide nanotubes doped with cesium. It purportedly offers better short-circuit current and power conversion efficiency than cells without cesium nanoparticles. They say it has optimal thermal stability under temperatures up to 800 C.

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.

The Sumitomo Corporation has simultaneously signed a contract with an EPC for a solar-powered green hydrogen production plant in Gladstone, Queensland, while also commencing a feasibility study for a grey-green hybrid hydrogen project in Oman. Considering the relative similarities in distance between the two countries and export markets in East Asia, the Japanese conglomerate looks to be setting the stage for competition in the hydrogen economy.

The latest edition of the World Nuclear Industry Status Report indicates the stagnation of the sector continues. Just 2.4 GW of new nuclear generation capacity came online last year, compared to 98 GW of solar. The world’s operational nuclear power capacity had declined by 2.1%, to 362 GW, at the end of June.

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 The research, which ousts outdated and cherry-picked data while showing the economically salutary effects of renewables, comes as 500 UNSW staff face the axe due to the impact of Covid-19.

The spherical 3D cells can reportedly generate around 101% more power than conventional flat solar cells. Measurements have also shown that the spherical cells provide a 10% lower maximum temperature compared to flat cells, while accumulating less dust.

The International Energy Agency has acknowledged dramatic falls in energy investment caused by the Covid-19 crisis but said renewables, including PV, offered an attractive proposition to investors as the dust settled, given their enticing economics and short turnaround times.

Scientists from Saudi Arabia have proposed a new PV panel cooling technique which employs an atmospheric water harvester. The device uses waste heat from the PV panel to collect atmospheric water at night and then releases it during the day to cool down the module. The researchers claim the device may also be improved to produce liquid water, which could be used for the cleaning of the modules.

German production equipment provider Schmid and Saudi chemical group Sabic are planning to begin activities at a new factory in Saudi Arabia, with production being expected to begin in 2021.
