wind energy

The material was used by scientists in the U.S. in electrochemical cells which use electricity to separate steam into hydrogen and oxygen. The researchers say the oxide of perovskite used in the electrode improves cell performance and reduces operating temperatures.

Differing finance costs across the continent are likely to see wind-rich, high electricity demand nations such as Germany, France, Austria and Belgium forge ahead with renewables at the expense of countries with plenty of sun but where borrowing is expensive, according to a German study.

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 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.

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.

Tennet needs more than €4.75 billion to invest in cross-border grid infrastructure between Germany and the Netherlands, as rising volumes of solar and wind are complicating network operations, said Dutch Finance Minister Wopke Hoekstra in a recent letter to the Dutch parliament, adding that the government may need to privatize the state-owned transmission system operator or sell off a stake in it.

Analysts have scrutinized the result of the recent A-4 auction which delivered, in theory, the world’s lowest price for solar electricity from an energy procurement exercise. The two plants in question, however, will sell 70% and 50% of their output outside the power deal signed in the auction.

The Western Australian Environmental Protection Authority is seeking public input on the massive Asian Renewable Energy Hub proposed for the country’s Pilbara region.

Construction on the facility was started eight months ago. In the future, the large-scale lithium-ion storage facility may participate in weekly auctions for primary reserve capacity.
