Wind

Researchers in China have conducted a numerical study on the wind sensitivity of offshore floating solar plants. They have tested six row-arrangements of panels and have found an optimal system configuration that is reportedly less sensitive to wind direction.

A Spanish research group says air flux variations over different parts of solar plants could also lead to mismatch losses. Past. studies have only looked at the benefits of high wind speed on PV arrays, which enhances module cooling.

If the industry has sufficient knowledge and experience to deal with the effects of strong wind, why do trackers still get damaged and destroyed? pv magazine’s Pilar Sanchez Molina looks at a recent example in Spain with PI Berlin’s Asier Ukar.

The heat storage tank is 45 m high and has a capacity of 56 million liters. It will store district heating water at a temperature of 98 C and, according to Vattenfall, will use heat produced with renewable electricity coming from the grid.

Hurricane-force wind gusts hit New England during a late-October storm, damaging at least one rooftop solar array and leading Commercial Solar Guy to offer a few pointers.

Through the procurement exercise, the Danish authorities want to allocate 429 MW of renewable energy capacity. The tender will be open to PV, wind, hydro and wave power projects.

The Danish Energy Agency has granted permission, to two power-to-X specialists, for the development of innovative projects without having to comply with the country’s energy legislation. This exemption is part of an upcoming pilot scheme to support new clean energy technologies, including green hydrogen.

BP, Iberdrola and Enagás will power a 20 MW electrolyzer with 40 MW of solar in Spain. Automotive manufacturers Hyundai, Stellantis, Toyota and BMW sent a letter to European Commission Vice-President Frans Timmermans asking to support the continued expansion of a 700 bar hydrogen refuelling network in Europe.

Furthermore, Michelin said it wants to become a world leader in hydrogen fuel cell systems and ScottishPower aims to build a green hydrogen plant at a wind power complex. Moreover, a study led by scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory suggested new strategies to design perovskite materials to speed up the oxygen evolution reaction (OER), a process that frees up molecular oxygen from water and is key for hydrogen production.

The Institute for Solar Energy Research Hamelin (ISFH) is testing if renewables can cover 80% of electricity and heating demand combined in some town districts in southern Germany.
