How world's biggest "green" power plant is actually INCREASING greenhouse gas emissions
It is touted as the flagship of Britain’s energy future: the world’s biggest green power plant burning wood pellets to generate renewable biomass electricity that will safeguard the planet for our children.
But today The Mail on Sunday can expose the hypocrisy that underpins the Drax power station in North Yorkshire – which far from curbing greenhouse emissions, is actually increasing them, while adding huge sums to the nation’s power bills.
Drax was once Britain’s biggest coal-fired power station. It now burns millions of tons of wood pellets each year, and is reputed to be the UK’s biggest single contributor towards meeting stringent EU green energy targets.
But astonishingly, a new study shows that the switch by Drax from coal to wood is actually increasing carbon emissions. It says they are four times as high as the maximum level the Government sets for plants that use biomass – which is defined as fuel made from plant material that will grow back again, therefore re-absorbing the CO2 emitted when it is burnt.
At £80 per MW/hr, Drax’s biomass energy is two-and-a-half times more expensive than coal – a cost passed on to customers. Last year Drax soaked up £340 million in ‘green’ subsidies that were added to British consumers’ power bills – a sum set to rocket still further. Without these subsidies, its biomass operation would collapse.
Perhaps most damningly of all, its hunger for wood fuel is devastating hardwood forests in America, to the fury of US environmentalists, who say that far from saving the planet, companies like Drax are destroying it. Drax denies this, saying it only uses dust and residues from sawmills, as well as wood left over when others log trees for purposes such as construction. Inquiries by The Mail on Sunday investigation suggests this claim is highly questionable.
Drax qualifies for subsidy because under EU rules, biomass is rated as ‘zero carbon’ – on the basis that trees used can be grown back.
Yesterday, the plant’s spokesman Andrew Brown refused to say how much subsidy it is being paid now, claiming this information was ‘commercially sensitive’.
But a Mail on Sunday analysis shows that in 2014, with two biomass units operational, the subsidy rose to at least £340 million – about three-quarters of Drax’s gross profit. The figure was calculated from the plant’s own public declarations of how much power it has generated from biomass, and known details of how much the subsidies are worth per MW/hr.
Now, with a third 650MW biomass furnace due to be lit in the next few weeks, the subsidy will grow again, in step with Drax’s output. By 2016, the total it has received will be well over £1 billion, with about half a billion being paid annually.
Drax is proud of its green credentials, and claims that it uses sawdust from sawmills and ‘waste wood’ or ‘leftovers’ – branches and smaller sections – discarded by commercial logging operations.
In fact, according to Drax’s own website, last year sawdust made up just 9.5 per cent of its pellets. A much bigger source is American hardwood trees – such as oak, sweetgum, cypress, maple and beech – supplied by US firm Enviva, which sells Drax a million tons of pellets a year, a quarter of the plant’s 2014 supply. Drax claims the wood it is supplied with is ‘sustainable’.
However, the Dogwood Alliance, a US environmental group, has investigated Enviva operations on the ground several times and found evidence to the contrary.
Late last month, Dogwood campaigner Adam Macon travelled with colleagues to the Enviva pellet plant at Ahoskie, North Carolina, where he saw piles of hardwood trunks 40 feet high being fed into the plant’s hopper – the start of the process where the trees are pulped and turned into pellets. These could not be described as ‘leftovers’.
Macon recorded the number plate details of an empty truck leaving the plant and followed it to a forested area 20 miles away. He waited as numerous other trucks, laden with tree trunks, left the forest for Ahoskie. Then, the truck he had been following left too, carrying its load back to the plant. The next step was to visit the area being cut. ‘To avoid detection, we trekked in from the back, through a forested swamp,’ Macon said.
‘We trudged through mud and water up to our knees. Wildlife buzzed, chirped and splashed all around as huge hardwood cypress trees towered above – a testament to the incredible biodiversity that exists in this region.’
Finally they reached the cut: ‘All that was left were the stumps of once great trees. They had destroyed an irreplaceable wetland treasure.’
MACON described how on another occasion last year, he hid closer to the actual cutting. ‘We saw the trees being cut, all the way to the bottom, then being put into a machine that cut off all the branches. The trunks were loaded into trucks, which we followed to Ahoskie.’
This operation is not illegal. Although they are home to dozens of species of animals and birds, some of them endangered, the forests are not protected. But US environmentalists claim that demand for biomass is hugely increasing the rate at which they are felled.
