A vision of a decentralized, renewable-powered electricity grid is being brought a step closer by scientists at the U.S. National Renewable Energy Laboratory. Their project, Autonomous Energy Grids, aims to take an overarching look at the solutions that will power this grid of the future, and to fill any gaps that appear between them.

The U.S. National Renewable Energy Laboratory reports further progress in bringing down the cost of III-V solar cells. Scientists have refined their ‘brand new, 50-year-old’ D-HVPE technology to speed up the production rate for gallium arsenide solar cells by a factor of more than 20. The development is a potential step toward making incredibly efficient solar cells cost effective for everyday purposes.

As renewable energy development is ramped up to address the climate crisis, negative side-effects should be avoided, especially when technology and resources could maximize the benefits. ‘Techno-ecological’ crossovers could ensure win-win outcomes for solar development and ecosystem and biodiversity conservation.

California based Hanergy subsidiary Miasolé has broken its own internal record for thin film cell efficiency, surpassing the 20% mark. The efficiency of 20.56% on a flexible substrate has been confirmed by U.S. National Renewable Energy Laboratory.

Using an application based on resource data and country-specific techno-economic inputs, a report has analyzed the costs of developing utility scale renewables in Southeast Asia and found abundant, cost-competitive potential.

A research paper from scientists at the U.S. National Renewable Energy Laboratory outlines a new approach to the production of gallium arsenide based cells. The approach, termed ‘germanium on nothing’, could enable the cost effective, high volume production of PV cells based on III-V materials such as gallium arsenide.

The annual expansion of photovoltaics throughout the world surpassed the 100 GW mark last year. The multi-terawatt market is looming on the horizon and PV is becoming a “game changer” in the global energy system in five specific areas, according to a consortium of research institutes.

Pumped hydro storage is highly cost competitive for large-scale energy storage, according to a report published by the San Diego County Water Authority. The report models a pumped hydro project as securing better financing terms than battery storage.

The oldest solar organization in the world, the International Solar Energy Society, dates back to 1954. President David Renné tells pv magazine about India’s solar dreams, the next best thing in solar technology and what renewables hold for the world’s future.

Former NREL employee pens paper to rebut claims conventional energy can supply the essential grid services needed to return to normality after network disruption. The author says claims renewable energy cannot provide such services are erroneous.
