Shale gas remains a costly, polluting option to source energy for the UK with doubtful long-term benefits – and it won't cut bills
The message from Downing Street could not be clearer: David Cameron announced on Sunday the government would be going "all out" for fracking, in an effort to bring to the UK the shale gas revolution that has sent gas prices plummeting in the US, and transformed huge swathes of its landscape.
Cameron's plans involve a giveaway of millions to communities that allow fracking, through a scheme whereby councils will retain all of the business rates liable on the sites, and payments to local communities from fracking companies of £100,000 upfront and 1% of revenues thereafter. These measures are supposed to unleash a wave of investment in hydraulic fracturing, the controversial method of extracting gas from dense rocks by blasting them with high-pressure water and chemicals.
The timing could not have been better, as the French company Total confirmed plans for the first big investment by a major oil company in fracking in the UK.
If the prime minister's plan is to win over opponents of fracking, he has plenty of work to do. The first major poll on fracking, carried out by the Guardian last year, found public opinion evenly split, with 40% in favour of fracking near their homes, 40% against and the rest undecided. Protests around the country have resulted in arrests, gathered angry meetings in town halls, and given rise to warnings from environmental campaigners of the dangers of water stress, pollution and climate change.
Cameron's enthusiasm for fracking – in stark contrast to the Conservatives' increasing rhetoric against renewables and "green" energy – highlights the number of unanswered questions on fracking in the UK.
First are the economics of investment. Total's initial pledge of £30m is far from the biggest slug of cash to be sunk into the UK's fledgling fracking industry. By early last year, the UK's fracking pioneer Cuadrilla – the only company to have fracked in the UK since modern techniques became available – had already spent more than £100m on its explorations, which comprised a single fracked well and three further exploratory sites in Lancashire. That was before last summer's drilling operations began at the site in Balcombe, in Sussex, where protestors gathered for several weeks last year. The company has yet to produce any gas or oil in the UK.
In an interview with the Guardian last year, Lord Browne vowed to spend "whatever it takes" to make fracking a commercial reality in the UK, but it is still unclear how much that is likely to be.
The size of the boost to the UK's broader economy is also the subject of debate. In announcing the business rates bonanza, Downing Street chose to quote a single estimate, of a £3.7bn a year benefit to the UK economy – taken from a report which was commissioned by the Institute of Directors and paid for by Cuadrilla. Its estimate of benefits and of 74,000 jobs includes such intangibles as people being employed in local shops to sell sweets to the site's security guards. Fracking sites require workers during the initial drilling phase, but once they are in production they are essentially empty.
What seems certain is that shale gas production will not bring down UK gas prices. The industry and independent experts are in agreement on this, and tellingly Cameron did not mention it in his statement, despite having claimed last year that shale would cut energy bills.
Energy company chiefs have repeatedly insisted that shale gas will not be a "game-changer" in the UK as it was in the US, in part because the quantities of the fuel available here are likely to be smaller and much more expensive to extract. In terms of price impacts, the US has operated as what the International Energy Agency terms a "gas island" - with exports all but impossible, the fuel has been used domestically, resulting in a drastic reduction in prices to as little as $2 a unit, compared with $10 to $12 in Europe and Japan.
Gas produced in the UK can easily be exported, however, and so will continue to fetch the same price as in Europe, and experts say those are highly unlikely to come down in the next decade. That could mean a boost to shale companies from a lucrative export market, but will do nothing for hard-pressed consumers.
Then there is the question of how many wells will be needed. Fracking companies like to point out that, after the initial drilling operations, the visual impact of each well is relatively small. A tall hedge can hide a wellhead, according to Francis Egan, chief executive of Cuadrilla, who calculates hundreds of wells will be required, with a density of as many as 18 to an area the size of a football pitch.
But going "all out" for fracking, to release the trillions of cubic feet of gas that are estimated to be trapped within dense shale formations under the UK, could require a massive expansion of drilling. Tony Bosworth, at Friends of the Earth, has calculated that many tens of thousands of wells may be needed all over the UK countryside.
That is because, although a fracking well can remain in operation for more than a decade after it is drilled, the amount of gas produced from one tails off rapidly after the first few years. Then the well needs to be refracked to squeeze out more gas, or – more usually – new wells need to be drilled nearby to get at the untapped fuel.
That means – as seen in the US – a continuous process of more and more wells needing to be drilled in an ever-increasing density and over a wider area to keep up production levels. While that has been possible over the wide and sparsely populated spaces of north America, it is a very different prospect in the UK, where many more people will be affected.
While fracking has the clear support of the prime minister, the UK's renewable power industry faces more flak than support from the Tory half of the coalition. Owen Paterson, the environment secretary, is a strong opponent of wind farms. Michael Fallon, the energy minister, crusades for a strengthening in the rules to let local people block them (while allowing fracking companies to drill under people's properties without their knowledge). The prime minister allegedly rages against "green crap" on energy bills – that is, subsidies to renewables – and the UK is opposing a renewables target at the EU level.
Before coming to power, and in the early days of the coalition, the Conservatives promised that residents near wind farms would also share in the economic benefits. But no such schemes have materialised – in stark contrast to the millions now on offer to communities near fracking wells.
The UK needs energy. It can come from imports, as most does today, or from indigenous sources: either below the ground, in the form of gas or coal, or above the surface in the form of wind and sun. All of these options carry costs and implications for the landscape, jobs and climate change. To go "all out" on one option is a gamble, and one on which voters have not yet been consulted.
