LNG, solar collectors improve round-trip efficiency of LAES systems
Scientists simulated several liquid air energy storage systems, comparing round-trip efficiency across configurations that include liquefied natural gas (LNG), solar, and Stirling engines, and further optimized performance using particle swarm methods.
Uzbekistan certifies first solar plant under I-REC system
Uzbekistan’s Ministry of Economy and Finance has approved an 823 kW solar plant to begin trading International Renewable Energy Certificates (I-REC), marking the country’s fifth renewable energy project to join the scheme.
Italy deploys 2.33 GW of solar in H1
Italy added around 1,092 MW of new PV systems in the second quarter of this year, with the rooftop segment driving demand.
The Hydrogen Stream: Trina sends first containerized hydrogen unit to Europe
Trina Green Hydrogen has shipped a containerized megawatt-class electrolyzer to Europe, while Fotowatio Renewable Ventures has selected Envision to support a green ammonia project in Brazil.
Croatia’s solar capacity reaches 1.1 GW
Croatia’s solar market continues to grow steadily, led by the self-supply and commercial and industrial (C&I) segments, while regulatory barriers stall utility-scale development.
From factory to field: How energy storage innovations are responding to Europe’s C&I segment
EUPD Research says the growth of the C&I segment in Europe’s energy storage market is driving new investment opportunities. The Bonn-based research group has explored what this growth means for both manufacturers and investors, as well as how manufacturers are addressing the needs of C&I installers and customers.
RWE secures environmental nod for 1,277 MWh solar-storage project in Chile
German utility RWE has secured environmental approval for its Los Durmientes project in Chile’s Antofagasta region, which combines a 243.6 MW solar plant with a 255.4 MW/1,277 MWh battery energy storage system (BESS).
Impact of hydrogen on silicon solar cell degradation
German researchers have reviewed recent studies on hydrogen-related degradation in silicon solar cells. They said the work is timely, with n-type silicon dominating production and antimony-doping emerging.
‘Soft-connected’ floating PV for offshore scenarios
An international research team has tested a floating PV system with a “soft-connected” configuration under offshore conditions, using six modular pontoons linked by elastic bar elements to simulate mooring lines and connection ropes.
European electricity prices fall despite drop in solar energy production
Weekly average electricity prices fell last week in France, Italy, Portugal and Spain, even as solar energy output also declined, according to AleaSoft Energy Forecasting.
