Optical photovoltaic converters for power transmission systems
Researchers from Spain have developed a novel model to evaluate optical photovoltaic converters used in high-power optical transmission. They have found that indium gallium nitride (InGaN) and indium aluminum nitride (InAlN) semiconductors could provide better results than gallium arsenide (GaAs).
Downsizing concentrating photovoltaics
A Spanish research team aims to bring concentrating photovoltaics closer to commercial viability by miniaturizing its components. The scientists claim that smaller CPV cells may reduce production costs and enable better CPV module assembly.
PPAs offer protection
Europe is witnessing a surge in power purchase agreements (PPAs). Over the past four years, the number of European PPA transactions has trebled. More than 180 deals were signed in 2022 alone and the trend is expected to continue, especially for solar projects.
Novel mathematical model to assess wind stability of solar trackers
Researchers from Spain have developed a method to estimate the critical speed a tracker can withstand. They found “good agreement” when comparing the model to experimental results.
The Hydrogen Stream: Masdar signs more hydrogen deals at COP28
Masdar unveiled a 10 GW Africa Growth Plan for renewable investments in six Sub-Saharan Nations at COP28 in Dubai this week, in addition to signing four additional hydrogen deals.
The Hydrogen Stream: Masdar signs hydrogen deals at COP28
At COP28, Masdar revealed a $16 billion investment deal with Iberdrola for green energy projects in Germany, the United Kingdom, and the United States. Masdar also signed a memorandum to assess the feasibility of a green hydrogen plant near the Port of Aqaba in Jordan.
The Hydrogen Stream: Rolls-Royce opts for SAF, not hydrogen in large aircraft
Rolls-Royce has told pv magazine that it prefers sustainable aviation fuels (SAF) for large commercial flights, but it continues to invest in hydrogen for mid-size aircraft in partnership with easyJet.
Hybridizing anaerobic digestion with photovoltaic-thermal energy
Scientists in Spain have proposed to combine anaerobic digestion plants with photovoltaic-thermal panels and have found that this combination may achieve an LCOE of $0.045/kWh across several locations in Europe and North America.
Spanish gas provider tests hydrogen-powered residential water heater tech
Madrileña Red de Gas is testing a heating system prototype developed by Germany company Vaillant that uses exclusively green hydrogen. The 25 kW system is equivalent in shape and size to a current natural gas heating system.
Industry pushes for ‘agricentricity’ at Agrivoltaics2023
At the Agrivoltaics2023 conference in France this week, companies such as solar developers and mounting system suppliers called for a more central role for agriculture, amid ongoing legislative and commercial developments. However, uncertainties remain over the next steps European countries might take to drive such initiatives.
