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

Researchers in Sweden have made advancements in developing sustainable solar fuels using iron-based systems, which are cheaper and more environmentally friendly compared to systems using rare earth metals. The study showed how iron-based molecules can transfer charge more efficiently, reducing energy losses and improving their effectiveness for solar fuel production. This breakthrough could contribute to the global energy transition by providing a viable alternative to fossil fuels using common metals. Although promising, further steps are required to finalize the process for producing solar fuels.
