Nuclear power is key to Ghana’s transition to greener energy but the switch is facing delays, a top official has told the BBC’s Climate Question podcast.

The West African nation wants one or two nuclear power plants to be up and running by 2030.

But Stephen Yamoah, executive director of state-run Nuclear Power Ghana, says the country is behind schedule.

“We should probably have been starting construction now, but we’re still engaging to identify the [right] vendor,” the nuclear power chief said.

The delays were caused by “financial” rather than “technical" issues, Mr Yamoah said.

The Ghanaian government had been in talks with China, France, Russia, South Korea and the US about building the nuclear plants, he added.
