New deep learning tech for PV inverter fault diagnosis
A team of scientists in the United States has combined both spatial and temporal attention mechanisms to develop a new approach for PV inverter fault detection. Training the new method on a dataset created in MATLAB/Simulink, the group has compared it to a series of other data-driven and statistical-based methods and has found accuracy reached 97.35%.
The Hydrogen Stream: NGV to install 100% hydrogen-fueled linear generator
National Grid Ventures (NGV) will test the world’s first 100% hydrogen-fueled linear generator at its Northport plant for 12 months, supported by $11 million in New York State funding.
The Hydrogen Stream: Thyssenkrupp Nucera electrolysis sales drop 20%
Thyssenkrupp Nucera reports a more than 20% drop in third-quarter electrolysis sales, with narrowing losses in green hydrogen and falling profits in the Chlor-Alkali segment.
New cooling gel could raise PV module efficiency by 12%
Researchers in Saudi Arabia have developed a hydrogel composite that absorbs moisture in solar modules overnight and facilitates evaporative cooling throughout daylight hours. The system has undergone lab tests and outdoor experiments on two continents.
Quantum-based energy management method for PV-powered buildings
Scientists from Cornell University combined quantum computing with model predictive control to manage the energy of two PV-equipped university buildings. Compared to deterministic approaches, the quantum strategy achieved a 6.8% improvement in energy efficiency and an annual reduction of 41.2% in carbon emissions.
Multi-constraint modeling for agrivoltaics
Researchers at Cornell University in the U.S. have developed a novel optimization model for agrivoltaic site design and benefits, which was demonstrated using irrigation-optimization relative to economic and environmental goals.
The impact of different cloud types on solar forecasting
A team of researchers have analyzed the impact of different cloud types on solar irradiance predictions. They found prediction models that factor in the physics of how clouds interact with sunlight are more accurate than models that do not consider cloud types.
The Hydrogen Stream: Air Products cancels three US projects
Air Products is pulling out of three US projects due to unfavorable economics and regulatory changes. The company says it remains focused on its Neom green project in Saudi Arabia and the Louisiana Clean Energy Complex
The Hydrogen Stream: MENA H2 projects surge in 2024
Dii Desert Energy says hydrogen projects in the Middle East and North Africa (MENA) surged to 117 installations in 2024, with 90% classified as green, while Plug Power has introduced the first-ever spot pricing program for liquid green hydrogen.
Agrivoltaic community solar under development in New York state
BlueWave has started working on three agrivoltaic community solar projects in Johnstown, New York, totaling 16 MW.
