Scientists in Singapore have developed a cell that could be used to power vehicles and boats, among other applications. The tandem device purportedly retains 90% initial efficiency after 500 hours of maximum power point tracking under continuous one sun illumination.

A 100kW/1.5MWh zinc-air battery will be installed in Queens, New York, in combination with a combined heat and power system and a PV array. The pilot project is intended to demonstrate the long-duration energy storage capability of the zinc-air battery.

Operated by Czech utility CEZ Group, the pilot solar plant will be located at different heights during the charge and recharge cycles of a pumped-hydro plant and the difference in height may reach up to nine meters.

Scientists in China analyzed defective solar cells based on Czochralski (Cz) silicon wafers and found Swirl defects may be responsible for an efficiency drop of up to 4.7%. According to them, the presence of Swirl defects could be mitigated by applying a heat treatment at a temperature above 1,050 degrees Celsius in a clean environment before the manufacturing of the solar cells.

With five public entities having committed RMB1.25 billion into a project to produce copper, indium, gallium, selenide solar modules five years ago, the joint venture has been abandoned at an estimated impairment cost of RMB1.42 billion.

Growatt’s new AXE LV battery covers a wide range of capacities, from 5kWh to 400kWh, and can support off-grid systems with power outputs of 3kW to 30kW.

Harwell Campus will provide a testbed for energy storage technologies coming from three U.K.-based innovative businesses, bringing their solutions one step closer to the market.

Germany-based Linde Engineering has started up a full-scale pilot plant in Dormagen to showcase how hydrogen can be separated from natural gas streams using its membrane technology. Furthermore, Abu Dhabi-based renewable energy developer Masdar has teamed up with French energy giants Engie and Totalenergies on two separate hydrogen projects and Sweden’s nuclear power company OKG signed its first contract with an external buyer to enter the hydrogen market as a producer and supplier.

The Suiso Frontier cargo vessel docked at Victoria’s Port of Hastings on Friday to take on the world’s first shipment of liquid hydrogen. The ship’s arrival is a landmark for the Japanese-Australian Hydrogen Energy Supply Chain pilot project, which sees liquefied hydrogen generated from brown coal, and an engineering milestone in itself. But while the Australian government describes the product as “clean”, experts maintain that carbon capture and storage technology has proven only to be an expensive failure.

According to Asia Europe Clean Energy (Solar) Advisory (AECEA), this huge capacity may not be met by actual demand in the global market. Furthermore, the consultancy reveals that solar module prices should reach a price level of up to RMB 1.75 ($028)/W by the second half of the year, and that in 2021 new PV additions totaled 53 GW with more than half of this capacity being delivered by distributed generation.
