The research could make viable a process that has enormous potential to replace fossil fuels and continue to use existing carbon-based fuel technologies without increasing atmospheric CO2.
Avoiding the use of metals in the electrodes is a huge advantage for dual-ion batteries and makes them much more sustainable, Ji said.
Fuel cells have long held promise as power sources, but low efficiency has created obstacles to realizing that promise.
The Swedish power supply is largely free of carbon emissions. Indeed, it is mainly based on a combination of hydroelectric and nuclear power combined with power exchange with neighbouring Scandinavian countries.
Decarbonizing global tourism represents a long-term investment, but given its tremendous growth, the relative cost is less than 0.1 per cent of the estimated global tourism economy in 2020 and increases to 3.6 per cent in 2050.
Tthe new artificial photosynthesis system offers a win/win situation for the environment: solar-powered green chemistry using sequestered carbon dioxide.
