Scientists discover how essential methane catalyst is made

New ways to convert carbon dioxide (CO2) into methane gas for energy use are a step closer after scientists discovered how bacteria make a component that facilitates the process. Recycling CO2 into energy has immense potential for making these emissions useful rather than a major factor in global warming. However, because the bacteria that can convert CO2 into methane, methanogens, are notoriously difficult to grow, their use in gas production remains limited.
