Renewables

In all ages, humankind decided to spend considerable amounts of the available productivity on special monumental projects. Managing climate change and rebalancing within the planetary boundaries is such an activity. The enormous energetic productivity of solar PV may evolve as the central pillar to create a sustainable civilization.

Conceived for stationary energy storage, the proposed sodium-ion battery configuration relies on an P2-type cathode material and an hard carbon anode material that reportedly ensure full-cell performance. Electrochemical testing revealed initial capacities of 200 mAh/g for the cathode and 360 mAh/g for the anode with capacity retentions of 42% and 67.4% after 100 cycles.

With silver prices rising, more large solar manufacturers are expected to switch to copper for cell metallization. Radovan Kopecek of ISC Konstanz tells pv magazine that he expects the entire industry to follow. Ning Song of the University of New South Wales says a small efficiency tradeoff may be acceptable if the cost savings are significant and do not introduce new reliability risks.

Austrian engineering group Andritz has signed a deal to supply the pump turbine units for a 500 MW pumped storage plant in South Korea, the country’s first new pumped storage project in over a decade.

Spanish tracker manufacturer Solar Steel has introduced an upgraded 2P single-row tracker designed to simplify assembly, improve standardization, and support deployment on complex terrain, including agrivoltaic projects.

Chinese manufacturer Sungrow has introduced a new utility string inverter, a three-phase hybrid inverter for commercial and industrial (C&I) applications, and a liquid-cooled energy storage system.

The twelfth edition of the International Renewable Energy Agency’s Renewable Energy and Jobs report, in collaboration with the International Labour Organization (ILO), provides the latest data and estimates of renewable energy employment globally. It finds global renewable energy jobs reached 16.6 million in 2024, but growth slowed. The solar photovoltaic sector is by far the largest employer in the renewable energy industry, accounting for over 7.2 million jobs worldwide. The report calls for stronger public action to build domestic supply chains and ensure a more inclusive workforce.

Spain’s electricity grid has lost nearly 2.8 GW of available capacity in two months, lifting substation saturation to 85.7% and leaving more than 5,200 facilities without spare capacity, according to new analysis.

Scientists have conducted a six-sphere literature analysis of agrivoltaics, considering sustainability, soil–crop productivity, socioeconomic resilience, solar power generation, spatial efficiency, and species. They found that, under optimal terms, agrivoltaics may generate over $1 trillion in added global agricultural income.

Output from Estuary Power’s recently-completed Escape Solar and Storage project more than doubles MGM’s share of solar energy.
