Do lead batteries have a role in the clean energy transition?

The Consortium for Battery Innovation has outlined research goals for advanced lead-based battery concepts, claiming the potential of the technology is “nowhere near fully exploited”. The group, comprised of lead-battery industry stakeholders, says such devices can play an important role alongside lithium-ion and other storage technologies in electric vehicles, renewable energy storage and other applications.

Siemens backs 5 GW green hydrogen plan for Australia

A massive green hydrogen production project has been unveiled in Western Australia with Siemens on board as technology partner. The location has been touted as Australia’s best for solar and wind power generation potential.

Questioning the quantum behavior of perovskites

Scientists at the University of Texas at Dallas have made a discovery they say has “altered the understanding of the fundamental properties of perovskite crystals”. Their findings could improve understanding of defect formation in perovskites, leading to devices with enhanced performance and stability.

Germanium use reduced in GaAs solar cells by new two-step process

Researchers from Canada have unveiled a new germanium deposition process which is said to eliminate threading dislocations and be significantly cheaper than previous approaches. The scientists say their technique creates nanovoids on the surface of the germanium layer which can attract and annihilate undesirable dislocations.

An oasis of PV

A new study shows solar may help reduce water pumping costs in a desert oasis of Mauritania significantly while reducing water losses. Researchers claim PV water pumping may also help prevent desertification.

New antenna for a better photon harvest

An Italian research team has developed a device that it says can easily be integrated into a PV cell, and can boost its efficiency by converting more light particles into a high energy state before they are absorbed by the cell. The scientists claim that their innovation could offer a green‐to‐blue photon upconversion yield as high as 15%.

Ireland allocates 110 MW in large scale storage auction

Originally intended to commission 140 MW of storage, the tender drew three winning projects: a 50 MW system and two 30 MW facilities. Eirgrid has estimated the total value of the contracts at around €6 million per year.

Australia’s Horizon to replace overhead network with solar and batteries

A recent project milestone saw the disconnection of properties from overhead lines and will enable 64km of poles and wires to be replaced by off-grid solar-plus-battery solutions.
