Wind Power

The Danish government has agreed to provide $19 million in funds for two large-scale hydrogen projects under development on the Jutland peninsula. The two projects will produce green hydrogen for the transport sector from renewables sources. Denmark’s largest energy company, Ørsted, has also announced plans for an ambitious 2 MW electrolysis plant with appurtenant hydrogen storage.

With the move, the Italian infrastructure fund has raised its operational renewable energy portfolio to 1 GW and secured access to the Spanish market for its EF Solare unit.

Spanish energy company Endesa is planning to build a 1,725 MW renewable energy complex in the Spanish town of Andorra, in the province of Teruel. The €1.48 billion project is set to comprise 1,585 MW of solar generation capacity, 139 MW of wind turbines and a large scale storage system, and will replace coal power plants Endesa wants to close in Andorra (Teruel) and Compostilla (León).

According to a new study by Finland’s LUT University, solar PV consumes between 2% and 15% of the water that coal and nuclear power plants use to produce just 1 MWh of output; for wind, this percentage ranges from 0.1% to 14%. Under the researchers’ best policy scenario, water consumption could be reduced by 75.1% by 2030, compared to 2015 levels.

The Danish Energy Agency allocated 252 MW of clean energy generation capacity, of which 83 MW was solar and 93 MW solar-wind hybrid facilities which included 34.1 MW of PV capacity. The average price premium to be paid on top of wholesale electricity rates to the successful bidders has fallen 30% in a year, prompting the authorities to muse they may be allocating too much public money to support such projects.

The mature renewable energies are the most efficient power resources to slow down global warming and reduce human health impacts, according to a new study published in Nature Communications. The authors claim renewable energy generation capacity is also the best way to reduce land use, toxicity and drinking water depletion.

The energy provider concluded its second renewables auction on November 13, and has contracted 121.6 MW of wind and solar. Selected projects will be granted a 15-year PPA and will have to begin commercial operations in 2023.

A researcher has proposed a new approach to apply maximum power point tracking techniques to optimize electricity production in wind-solar power projects. The permanent magnetic synchronous generator hybrid model used in the study is based on a multi-input rectifier stage which is said to be able to eradicate current harmonics and eliminate the need for extra input filters.

The International Renewable Energy Association says the integration of hydrogen into the energy transition will not happen overnight and electrolysis costs will not be halved until the 2040s. That hydrogen and related products could revolutionize the world energy landscape, however, is not in doubt.

A new report in Sweden suggests that renewables are an ideal source of power for marine vessels, based on a case study in which solar PV and proton-exchange membrane fuel cells, combined with a diesel generator, were used to reduce the greenhouse gas and particulate emissions of cruise ships by almost 10%.
