Middle East

Saudi scientists have tested several cooling technologies for solar panels and have found that active techniques work better than passive ones under harsh climatic conditions. The most effective one consists of a system based on four heat pipes immersed in a box of liquid, as liquid bulk, integrated with the back of the solar panel.

If the three record-busting low solar price tariffs recorded in the Middle East in the past 18 months are to be believed, renewables-powered hydrogen in prime sites in the region could already compete with gas-plus-CCS production, according to IRENA. Has the Gulf discovered the new petrol?

Saudi scientists built the cell’s electrode with a hole-transporting molecule called Br-2PACz and not with the commonly used PEDOT:PSS. It helped improve the photovoltaic cell efficiency by around 0.9%.

Private sector fossil fuel spending on exploration is drying up just as modest rises in clean energy investments are being observed. With stock market investors increasingly embracing renewables, the IEA has observed positive signals in its latest energy investment report, but warned we are still doing far too little to keep global heating at bay.

Details are thin on the ground as yet, but Emirati newspaper The National has reported the port facility will be linked to an 800 MW solar field at the site.

The project is the first solar-powered green hydrogen facility in the Middle East and North Africa (MENA) region.

It’s claimed the decentralised desalination system can deliver a levelised cost for desalinated water of US$0.7-4.3/m3, depending on PV costs and electricity prices. It was built with several concentrated photovoltaic/thermal (CPV-T) collectors, a hot water tank, a V-MEMD module, a seawater feed tank, and a distillate tank.

Jordanian government officials have met with a delegation from Fortescue Metals Group to discuss investment opportunities in green hydrogen and ammonia, although details of the meeting remain scant.

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.
