Using air conditioning to cool down PV modules, dry dishes

An international research team has investigated how air conditioning may be used to reduce the operating temperature of PV panels. The researchers not only found that the proposed approach is technically viable, but they also tested the use of excess heat from the panels for drying dishes.

California to use flexible appliances for renewable energy integration

California plans to shift 3 GW of load from dirtier, more expensive times of day to cleaner, less expensive times by setting flexible demand standards for many types of electric appliances. Global interest in California’s work is high, according to a state agency commissioner.

Photovoltaics for biomethanation

Researchers in Denmark have studied the technical and economic feasibility of biomethanation through large-scale PV power generation. They said that the intermittent PV-driven biomethanation process matches the efficiency of continuous processes after several days.

The Hydrogen Stream: H2EX’s Australia ‘natural hydrogen’ survey set for Q4

The International Energy Agency has warned that lagging policy support, rising costs, and supply chain disruptions threaten the profitability of low-emission hydrogen, while the Commonwealth Scientific and Industrial Research Organisation (CSIRO) has identified hydrogen seeps in South Australia.

Staubli invests in US developer of solar inspection robots

Switzerland’s Staubli Electrical Connectors says it has invested in California-based PV robot developer OnSight Technology to fund the advancement of its algorithms and artificial intelligence technology.

New control strategy for PV-powered water pumps operating under variable atmospheric conditions

Scientists in Turkey have developed a new algorithm to optimize the efficiency of PV-powered water pumps. The novel technique is based on the Extended Kalman–Bucy filter, which is a predictor-corrector algorithm used extensively in control systems engineering for estimating unmeasured states of a process.
