Only5mins! – ‘Additionality’ must be adhered to in Africa’s green hydrogen development

Chigozie Nweke-Eze is an economist, geographer and founder of Integrated Africa Power. He sat down with pv magazine to discuss green hydrogen development in Africa, from the project pipeline to the necessity of “additionality” when it comes to ensuring hydrogen doesn’t become yet another exploited African resource.

Passive solar module cooling tech based on paraffin wax

Egyptian researchers have used paraffin wax as a phase-change material (PCM) to reduce the operating temperatures of PV modules. They have found that the material improves power yield by more than 15%, compared to a reference module without cooling.

Africa closing in on gigawatt-level solar

Solar installations across Africa hit 949 MW in 2022, bringing cumulative capacity past the 10 GW mark, according to the African Solar Industry Association (AFSIA). While that may seem underwhelming for such a huge region, it shows that countries are taking big steps toward realizing the entire continent’s PV potential.

Hydrophobic nanocoating to reduce soiling in solar panels

Scientists in Egypt have created a self-cleaning, hydrophobic coating for solar panels that reportedly increases their efficiency by more than 30%. They used a coating solution based on polydimethylsiloxane (PDMS) and silicon dioxide (SiO2) nanocomposites, mixed with ethanol and isopropanol.

COP27 was a crucial step forward for hydrogen – here’s why

Three import deals signed by the EU at Sharm El Sheikh during this month’s COP27 summit show the European Union is serious about harnessing green hydrogen for its heavy industry, and about distributing the fruits of the energy transition on an equitable basis.

The Hydrogen Stream: Egypt to host 3.6 GW of electrolyzers at Suez Canal

Globeleq has revealed plans to build a green hydrogen facility in the Suez Canal Economic Zone, and Air Liquide has agreed to run a hydrogen production unit for TotalEnergies in France. Doosan Fuel Cell, meanwhile, has said it will export 105 MW of hydrogen fuel cells to China by 2026.

The Hydrogen Stream: Germany to import green ammonia from Saudi Arabia from 2026

Germany has decided to build its first green ammonia import terminal in Hamburg, in collaboration with Air Products. Egypt, meanwhile, has signed $85 billion of hydrogen framework agreements.

The Hydrogen Stream: Hydrogen production from industrial byproducts

US scientists have reported efficient plasmonic photocatalysis for the production of hydrogen from hydrogen sulfide, with no external heat source. Egypt, meanwhile, has started commissioning Africa’s first integrated green hydrogen plant.

Subsea cable to bring wind, solar power from Egypt to Europe

Copelouzos Group plans to lay a submarine cable to link 9.5 GW of wind and solar power in Egypt to Greece’s Attica region. The project was recently included in the Entso-E 10-year development plan.

Ultra-fast synthesis of nanocomposites for sodium ion batteries, supercapacitors

Researchers in Egypt have developed a synthesis method that uses the high microwave absorbance of silicon carbide content in rice straw ash and takes just 60 seconds to produce sodium iron phosphates-carbon nanocomposites (NaFePO4-C), which can be used as sodium ion battery cathodes and as symmetric supercapacitors.
