Britain's Drax Power Station Is Closer To Coal Free After A Fourth Unit Is Converted To Biomass
- Jun 07, 2018 -

Britain's Drax power station is taking its fourth coal-fired power generation unit as part of an outage plan and is preparing to convert it into sustainable biomass fuel, further fulfilling its ambition to be coal-free.

When the upgrade is complete, two-thirds of the plant's capacity will generate renewable energy.

The Drax power station has invested about 700 million pounds to upgrade half of the power plant and related infrastructure, supply chain to use sustainable biomass replace coal, will become Europe's biggest decarburization projects.

The conversion of the fourth unit is expected to be completed this summer and will resume in use in the second half of 2018.The conversion cost is well below the previous conversion level, about 30 million pounds.

Drax engineers will upgrade the plant by reusing the redundant infrastructure left over when the company first used coal to burn biomass on a large scale eight years ago.

A test last year confirmed that by retrofitting the old co-combustion delivery system, compressed sawdust particles could meet the delivery requirements of a fully converted fourth generating unit.

Andy Koss, Drax's chief executive, said: "changing the fourth unit from coal to biomass is another milestone in the transformation of the plant.It will extend plant life, protect Drax power stations and supply chain jobs, and provide cleaner and more reliable electricity to millions of homes and businesses.

"The ongoing transformation demonstrates our engineering expertise, skills and ingenuity at Drax power stations.The team developed some very innovative solutions for this upgrade, taking advantage of all the knowledge we have gained so far from using the sustainable biomass business.

Once it's back online state, the fourth unit will help the power station is located in north Yorkshire selby provide important reliable and flexible power grid needs, in order to maintain safety supplies, because more renewable energy will be launched and the industry continue to decarburization.

Once the conversion is complete, Drax will turn its attention to the other two coal units, which it plans to replace with gas-fired ones.It is developing a closed-cycle gas turbine that can provide up to 3.6GW of capacity and up to 200MW of battery storage capacity.

Plans for a gas project at the Drax plant have been submitted to the planning watchdog, which has 28 days to decide whether to accept the application.If accepted, the recommendations will be reviewed by the planning and inspection bureau and then considered by the secretary of state for commercial energy and industrial strategy, which is expected to be decided in 2019.

Over the past five years, Britain's coal-fired capacity has fallen 84 per cent as low-carbon generation has increased.
