Portuguese solar plants – tendered and merchant – remain in limbo

One of the first items in the in-tray of the country’s new Socialist Party government must be to unblock Portugal’s seemingly huge appetite for PPA-backed merchant solar sites and to deliver the PV projects which were tendered by the authorities, to global acclaim, in 2019 and 2020.

Vanadium redox flow battery to control extreme power ramps in rooftop PV

Researchers in Portugal have tested how vanadium redox flow batteries can be integrated with rooftop PV to balance the system load to ensure firm power output. They proposed a 5 kW/60 kWh battery configuration for a 6.7 kW building-integrated PV microgrid. According to their findings, the battery can be used in different energy management strategy scenarios to better complement solar photovoltaic generation.

Solar the fastest growing European clean power source

The latest numbers released by EU data body Eurostat indicate renewables, including hydropower, contributed 37% of Europe’s gross electricity consumption in 2020, up from 34% a year earlier.

Solar redox flow cell for residential energy storage

The device was designed by scientists in Portugal to optimize light absorption by the semiconductor and ensure an effective diffusion of redox species while offering minimal electronic and ionic transport resistance. The cell has a 25cm2 photoactive area and relies on ferrocyanide/anthraquinone redox flow chemistry and a nanostructured hematite photoelectrode.

Detergent for solar module cleaning and protection

Developed and distributed by Portuguese start-up ChemiTek, the detergent is claimed to reduce water consumption by about 50% and increase energy production by up to 5%. The product was recently certified by the German laboratory TÜV Sud, according to the EN 61215 standard.

EDP becomes largest shareholder of Sunseap

The operation is part of the Portuguese utility’s plan to deploy another 13 GW of renewable energy capacity by 2025.
