Chemitek Solar launches cleaning solutions for agrivoltaics
Portugal-based Chemitek Solar is developing biodegradable cleaning and anti-soiling products for PV panels that share land use with agricultural production.
The Hydrogen Stream: Japanese researchers develop green rust catalyst
Japanese researchers have developed a green rust–based catalyst for sodium borohydride, while South Korean scientists have created a framework to assess liquid hydrogen storage tanks for unmanned aerial vehicles (UAV).
Saharan dust events can reduce PV power output in Mediterranean area by up to 50%
New research from Hungary shows that Sarahan dust events can reduce PV power output in five Mediterranean countries by an average of 25-40%. The scientists stressed the need for including real-time dust monitoring and cloud interactions in solar forecasting.
The Hydrogen Stream: France, Germany back nuclear H2, Southwestern Corridor
France and Germany have pledged support for the Southwestern Hydrogen Corridor and have agreed to collaborate on nuclear-based hydrogen support and joint research.
Portugal surpasses 6.1 GW of solar capacity
Portugal’s solar capacity reached 6.17 GW in May, according to the country’s renewable energy association. While distributed generation is steadily expanding, a quicker rate of deployment across all market segments will be needed to meet 2030 targets.
Portugal to hold energy storage auction before January 2026
Portugal plans to hold an energy storage auction before January 2026 as part of a €400 million ($462.2 million) initiative to enhance grid resilience following an April blackout.
Assessing PV cell, module reliability via Arrhenius equation
Researchers in Portugal have used the so-called Arrhenius aging model to measure the temperature behaviour and reliability of different solar modules. Their analysis showed that long-term module performance can diverge significantly depending on the manufacturing processes.
Italy, Portugal, Spain break daily solar production records
AleaSoft Energy Forecasting’s latest analysis finds weekly average electricity prices dropped across most major European markets last week, driven by lower gas and CO2 emissions prices and in some cases, an increase in solar energy production.
Optimizing Carnot batteries for renewables storage
Based on the the heat pump-organic rankine cycle, scientists in Portugal have created six different models of Carnot batteries for stationary storage. They investigated 16 different combinations of working fluids and created a multi-objective optimization for the best candidate.
European electricity prices rise despite negative weekend values
AleaSoft Energy Forecasting’s says weekly average electricity prices increased across most major European markets last week, despite an influx of negative prices over the weekend. Portugal, meanwhile, broke its all-time record for solar energy production.
