HVDC transmission serves mostly wind and hydro power, not solar

A report from The Brattle Group and DNV recommends clearing barriers in the U.S. to high-voltage direct current (HVDC) transmission. HVDC transmission projects show many cost-saving use cases, but so far, transmitting solar power is rarely among them.

Hydrogen stations could avoid unplanned shut-downs with predictive models, research finds

The NREL study focuses on a specific model that uses data to reduce the frequency of unscheduled maintenance, and increase the frequency of preventive maintenance.

What causes batteries to degrade?

Having discussed battery chemistry in a previous article, Volytica diagnostics here examines the causes of battery degradation and how to extend device lifetimes, ahead of a pv magazine webinar tomorrow.

Sunrise brief: Unraveling the IRA’s domestic content rules

Also on the rise: How long do residential solar batteries last? Sharp unveils all-black 420 W TOPCon solar panel with 21.51% efficiency. And more.

Heat pump design to reduce footprint of solar thermal installations

A U.S.-Mexican research team has investigated how linking heat pumps with solar thermal collectors may help reduce the surface needed to deploy the collectors themselves.


Solar for water deionization

Scientists in Canada have combined PV power generation with water purification based on capacitive deionization (CDI), which is claimed to have low operational cost, enhanced energy efficiency, and less water rejection than conventional purification techniques. The solar-powered system prototype is able to produce more water than a conventional CDI system on a sunny day.

IEA-PVPS releases guide for applying innovation system approach to BIPV

IEA-PVPS has published a new handbook that provides support for Technological Innovation System (TIS) analysis for building-integrated photovoltaics (BIPV).

U.S. utility testing 5 MW, 10-hour organic solid flow battery

German battery manufacturer CMBlu is supplying its 5 MW, 10-hour-duration organic solid flow long-duration battery technology to a US utility project, featuring high-performance organic energy storage molecules.

A terawatt of solar module capacity expected within 16 months

Clean Energy Associates projects that major Chinese manufacturers will achieve a global solar module manufacturing capacity of 1 terawatt by the end of 2024. Furthermore, this capacity is projected to hit that same mark within China’s borders by 2025.

Anode-less redox flow batteries capable of fast cycling

Researchers in the US have demonstrated that replacing the planar lithium anode in a redox mediated lithium-sulfur redox flow battery with a high surface area scaffold enables 10 times faster cycling, up to 10 mA cm−2, without short circuit or voltage instability.
