Fossil fuel replacement: Sustainable solar fuels could be developed using common metals

Swedish researchers have overcome a major obstacle in solar fuel production by revealing how iron-based molecules can transfer charge more efficiently to acceptor molecules. They discovered that neighboring molecules can help complete charge transfer, reducing energy losses in iron-based systems. This breakthrough could lead to cheaper, sustainable alternatives to fossil fuels using common metals instead of expensive rare Earth elements, potentially transforming energy systems for transportation, heating, and industry.
