The process of creating synthetic graphite from specialty petroleum coke is energy intensive and complicated, Georgiev noted, adding that in the last five decades no new synthetic graphite producers have emerged.

“It is a very difficult process, it is very difficult to produce,” he said. “So it's very difficult to add new capacity.”

He went on to explain that some of the market’s production capacity relies on operations that are very old and tend to require long periods of maintenance, making their supply status precarious.

“For example, last year the (Humber) refinery Phillips 66 operates in England went (offline) for four months for maintenance, which took supply out of the market,” he said.

The other point is that burning fossil fuels to make the petroleum coke isn't very green ... which is exactly why we are going away from coal fired power stations
