Improving PV-powered water electrolysis with external fields

Australian researchers have analyzed different ways to improve the efficiency of PV-powered water electrolysis for hydrogen generation. They include the use of magnetic fields, light energy, ultrasonic fields, and pulsating electric fields. Energy costs remain prohibitive, but molecular movement and the redistribution of molecules in water during electrolysis could open a path to viability.

Norway’s residential PV market saw small contraction in 2020

Around 31.7 MW was installed and 1,613 rooftop PV systems were deployed under the Plusskundeordningen solar rebate program last year. This compares to 31.9 MW and 1,666 projects a year earlier. Low power prices and policy confusion are the main causes of this slight market contraction.

Ireland outlines net metering scheme for solar and renewables

The scheme is now under public consultation and is aimed at enabling citizens, farmers, business owners, and community organizations to sell excess solar power to the grid.

Netherlands deployed 2.93 GW of solar in 2020

At the end of December, the country’s cumulative installed solar capacity surpassed 10 GW. PV was able to cover around 6.6% of Dutch electricity demand last year, according to a new report from Dutch New Energy.

The best redox flow battery tech

Batteries based on vanadium or zinc bromide represent the cutting edge of redox flow storage tech, an international research team has claimed. They have identified challenges and opportunities for about a dozen redox flow storage technologies, while providing estimates of their current and projected levelized costs of storage.


Solar offers multiple options to manganese mine in Botswana

Canada-based Giyani Metals is planning to build a solar plant for its manganese mining site in Botswana. Three kinds of projects, with capacities ranging from 14 to 60 MW, are being considered. The power generated by the facility may be either consumed entirely by the mine or also sold to the grid under different scenarios.


Tidal flats in eastern China to host 300 MW of solar

Developers have already connected 3 MW of capacity in what is purportedly destined to be the world’s largest PV array on a coastal tidal flat. The project, which is particularly challenging due to tidal fluctuations, will feature PV components designed to cope with salt and water damage.

Is China really opening its energy market to EU enterprises?

In an interview with pv magazine, Frank Haugwitz – the director of the Asia Europe Clean Energy (Solar) Advisory (AECEA) – explained how the recent China-EU investment deal could offer more opportunities to European companies in China’s renewable energy market. He said the agreement shall provide transparency over policies, regulations, financing, and subsidies. And competition shall grow, especially in the C&I solar segment, he added.

Smart meters disrupt residential PV segment in Belgium’s Flanders region

A recent ruling of the Belgian constitutional court has canceled the 15-year grace period granted to residential PV system owners to keep operating under net metering despite the arrival of smart meters. The Flemish government said it will provide some compensation for the financial losses that this decision will cause.


Eastern Indonesia may become hub for large scale PV deployment

The Indonesian government has announced the construction of a big PV plant in the eastern part of the country, explaining that the region is particularly suitable for solar development due to its dry climate and high solar radiation levels. The region is indeed the most suitable area for solar parks, due to land availability and high electricity generation costs.
