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.

Floating PV plant operators may achieve additional revenue through non-evaporated water

A group of researchers from Italy investigated the economic competitiveness of various ground mounted and floating PV systems with regard to cost and performance, taking into consideration revenues due to reduced water evaporations. They found that the use of non-evaporated water at photovoltaic system sites can achieve revenues greater than $3/kW if used for irrigation and higher than $4/kW if sold to generate hydroelectricity.
