DNV

Energy consultancy DNV has published a data validation and methodology review of solar irradiance data provider Solcast, a company it acquired early last year. The review found that the forecasting specialist’s figures are “at or above industry standards.”

Reports of broken module glass with no obvious cause have begun to crop up at large PV projects. Module design, glass manufacturing, and interactions in the field between modules and trackers are at play and a clear solution has yet to emerge. Early signs suggest an update to certification standards may be needed.

Italian researchers have compared the performance of hydrogen and electric buses in northern Italy, while DNV has released its guidelines to validate claims related to low-carbon renewable hydrogen and ammonia attributes.

Hydrogen and battery technologies are expected to play an increasingly vital role in the UK’s transition to net zero by 2050, but the varying time scales of their rollouts are driving uncertainty in predicted market share profiles over time, according to a new report.

Norway’s DNV has acquired Australia-based solar data specialist Solcast for an unspecified sum.

The expected lifetime of PV inverters is significantly shorter than that of modules. In many projects, inverter replacement is included in financial calculations from the start, despite the high costs. Research is being conducted into the causes of faults to develop more durable inverters and components. But plant design can already improve the lifespan of inverters in use today, reports pv magazine Germany’s Marian Willuhn.

While near neighbors, the electricity generation of the countries of Southeast Asia couldn’t be further apart. Indonesia burns locally mined coal; Malaysia has reserves of oil and gas; and populous Singapore, Vietnam, and the Philippines depend on fossil fuel imports. They could all benefit from increased solar electricity but higher grid capacities and interconnection are key for an opportunity to unlock the power of the sun.

Germany made efforts this week to expand hydrogen ties with the Gulf states, and Japan announced plans to team up with several nations to ramp up hydrogen production. ICIS, meanwhile, has started offering Europe’s first market-linked renewable hydrogen assessments.

DNV recently evaluated 19 battery cells through its testing program and found that lithium iron phosphate (LFP) cells from Chinese battery makers CATL and Narada offer the best performance in stationary energy storage applications.

A Norwegian startup has patented a floating solar system made of panels laminated on top of double-aluminum sheets. The pre-stringed floats are rolled out on site and towed into place.
