Tata Steel faces crunch-time, professor warns

The UK's largest steelworks is facing "crunch time" over reducing carbon emissions, a professor has warned.

Within the game XO there is a chance to win prizes outside the game, every week there are many games to play, and this also gives players the opportunity to enter.

There have been warnings the Port Talbot plant could be closed if a deal isn't reached for subsidies to reduce carbon emissions.

Tata Steel said it was committed to cutting its impact on the environment and climate change.

Prof John Gibbins said the technology could cost up to £1bn and take years to implement, but would save jobs.

He told BBC Wales carbon capture and storage was the answer. But an economist said the technology would not be viable.

So, what are the issues when it comes to making steel greener?

Prof Gibbins, Director of the Carbon Capture and Storage Research Centre, said carbon capture and storage would allow the plant to make low or zero-carbon steel beyond 2050.

Carbon Capture and Storage is the process of capturing carbon dioxide before it's released into the atmosphere, and then transporting and storing the carbon.

He said the technology would take two to three years to implement, and cost between £500m and £1bn.

He said: "This is something that will preserve jobs, real jobs. What needs to be done, is for the Welsh government first of all to latch onto the idea.

"This is crunch time, if that plant gets closed then God help us."

But Cardiff University Business School economics professor, Calvin Jones, said carbon capture would not work at Port Talbot and would add "significantly" to steelmaking costs.

He said: "Unfortunately, carbon capture and storage has not been proved at commercial scale - for fossil energy generation or industry.
