Scientists from the Adelaide University & CSIRO have developed a catalyst that under the influence of solar energy can convert carbon dioxide (CO2) into synthetic natural gas.
When using hydrogen as a fuel maintaining safety is a challenge.
Whilst the process has its own challenges, combining hydrogen with carbon to produce methane as a gas is a safer option.
However, the major obstacle has been to try & identify an energy efficient process that facilitates the conversion of CO2 to methane.
Using nano-technology and metal organic frameworks the researchers were able to develop a catalyst which operates at lower temperatures and pressures, meaning the use of solar energy becomes viable.
