Energy giant AGL has also come onboard and will assess whether the technology would be suitable for its soon-to-retire Liddell facility.
Global Energy Ventures, the firm currently working on a 2,000t hydrogen cargo ship, has announced the commencement of construction on a 430t pilot-scale version to service the emerging market for economies wanting begin blending small amounts of green hydrogen into existing gas networks by mid-2020s.
Spanish mounting system provider Alusín Solar has developed a solution to enable the transit of installers on roofs. It has recently commissioned a production line for this product, which it dubbed Carex.
State-owned electricity generator Stanwell has secured land in Aldoga, west of Gladstone, to build a large-scale 3 GW hydrogen electrolysis plant as part of its partnership with Japan’s Iwatani Corporation, well established in the hydrogen production industry.
A U.S. scientist has developed a computational framework that assesses how well a hypothetical agrivoltaic project would perform in achieving desired outcomes such as the volume of PV electricity produced, and energy-to-agriculture. The method considers the high-frequency decomposition of solar irradiance into multiple rays and analyzes how these rays are propagated forward in time, to assess multiple reflections and absorption for various system configurations. It also takes into account panel inclination, panel refractive indices, sizes, shapes, heights, and albedo.
The new product has an efficiency of 98.8% and a European efficiency of up to 98.5%. It features 10 independent maximum power point tracking (MPPT) inputs, with MPPT voltage ranging from 180-1000 V.
It’s one thing to set a target for net zero, another to chart a course that will get you there in competitive form. Services are emerging to bridge the gap.
Commodity trader Trafigura and Oslo-based ammonia leader Yara International ASA have signed a Memorandum of Understanding that will see supply of clean ammonia as well as joint R&D projects as the two companies look to promote clean ammonia as a shipping fuel and develop its value chain and infrastructure.
NASA scientists have partially cleaned up the solar modules of the Insight lander operating on Mars, by using grain sands collected nearby and trickling them on the panels during the windiest time of the day. This handmade technique has made it possible, according to them, to increase the PV array’s yield of about 30 watt-hours of energy per ‘sol,’ or Martian day.
A review of existing research on any particular topic “should provide some novel insights”, says UNSW solar researcher Dr Matthew Wright. UNSW’s new paper shows defect engineering of SHJ solar cells has come a long way, but what if these proven efficiency gains could be better applied?
Dubbed Gismo Power, the appliance is entirely mobile, can be grid-connected, and may be folded for storage.
An international team of scientists fabricated perovskite solar cells which retained almost all of their initial 21% efficiency after 1,000 hours under continuous operation at their maximum power point. The researchers credit this performance to their discovery of an additive that served to ‘block’ ions that cause device degradation, and also hope their work will contribute to an improved understanding of the relationship between efficiency and stability in perovskite PV.
As PV manufacturing lines continue to get larger, keeping track of the measurement data that’s vital for quality and process control becomes an ever more herculean task. Flashing equipment supplier h.a.l.m. has developed a software solution that keeps all of this data in one place and provides operators with a real-time view of production line performance and quality. pv magazine caught up with Managing Director Michael Meixner to discuss the latest on big data in PV manufacturing.
The proposed technique is based on radiative cooling and consists of a glass coating made with a two-dimensional subwavelength nanostructured grating, which is imprinted in soda-lime glass and has enhanced mid-infrared emissivity, and a micro-structured grating. The temperature decrease provided by the nano-micro-grating coating was found to be approximately up to 5.8 degrees Celsius.
