- Until now, they explained, an external source of electricity was required in order to power the process.
- However, the team added, the current cost of operating the new technology is too high to be used commercially.
- Prof Logan said that the technology to utilise this process to produce hydrogen was called microbial electrolysis cell (MEC).
- “The breakthrough here is that we do not need to use an electrical power source anymore to provide a little energy into the system.
- “All we need to do is add some fresh water and some salt water and some membranes, and the electrical potential that is there can provide that power.”
