IoD Member Survey
In April 2012, the IoD polled 1,095 IoD members for their views on the potential of UK shale gas. While there were some mixed views, and a degree of uncertainty, members were positive overall:
58% said that extensive development of the UK’s shale gas resources would have a positive or very positive impact on British businesses. By contrast, just 7% thought it would have a negative or very negative impact on business, while 22% said it would be neither positive nor negative.
Views were mixed on the possible safety and environmental risks of hydraulic fracturing. 36% thought that the risks were significant, compared with 17% who thought they were insignificant and 27% who felt they were neither significant nor insignificant.
Overall, almost half (48%) of IoD members agreed that the benefits outweighed the risks, compared to 18% who thought that the risks outweighed the benefits, and 15% who neither agreed nor disagreed with the question.
Regionally, IoD member views are very similar. In all regions of the UK:
More than 50% of members think that shale gas will have a positive impact on business.
Less than 40% of members think that the risks of fracking are significant.
At least 45% of members think that the benefits outweigh the risks.
General Comments
On 21 September 2012, the IoD published a report, Britain’s shale gas potential, which can be found here http://www.iod.com/Influencing/Press-Office/Press-releases/British-shale-gas-could-create-35000-jobs-reduce-carbon-emissions-and-lower-energy-prices
The IoD’s overall view can be summarised as follows:
The UK has a major opportunity to develop a cheap and reliable domestic source of energy, creating jobs, reducing the need for gas imports and improving the environment by replacing coal in electricity generation. Shale gas will not solve all our problems, but it can be an important part of the energy mix.
Cheap gas-fired turbines powered by UK shale resources could also prove to be the perfect complement to renewable generation, providing power when the wind isn’t blowing and the sun isn’t shining.
The risks of hydraulic fracturing should be viewed alongside those of conventional oil and gas extraction. Provided industry best practice is followed, and strong regulation and monitoring are in place to enforce this, fracking should be permitted to proceed.
Overall, we should be enthusiastic about developing a new domestic source of energy.
Answers to Specific Questions
1. What are the estimates for the amount of shale gas in place in the UK, Europe, and the rest of the world, and what proportion is recoverable?
The International Energy Agency has published the following table of global technically-recoverable reserves of natural gas (see Table 1), which is the most recent global estimate that we know of. I have highlighted the column for shale gas. Note that global production is currently 3.3 trillion cubic metres a year.1
Shale accounts for 28% of global natural gas reserves—a significant portion—and is very well distributed, with large resources in all parts of the world, apart from the Middle East (Note that the IEA divides Europe in two).
In the US, shale accounts for nearly a quarter of natural gas production. If shale were to account for 25% of the current level of global natural gas production, assuming a recovery rate of just 10%, current shale gas resources would be sufficient to meet 25 years of global production.
In the US, shale gas recovery rates have averaged 18%.2 If this was replicated globally, then shale resources would meet 25% of current global natural gas production for 40 years.

In the UK, in 2010 the British Geological Survey (BGS) estimated onshore shale reserves at 5.3 trillion cubic feet.4 The BGS is set to revise its onshore data substantially upwards later this year, possibly to as high as 200 trillion cubic feet.
Meanwhile the exploration companies have identified far higher resources:
Cuadrilla—200 trillion cubic feet.
Eden Energy—12.8 trillion cubic feet.
IGas—10 trillion cubic feet.
Dart Energy International—66 trillion cubic feet.5
These resources add up to nearly 300 trillion cubic feet in total, compared to UK natural gas consumption in 2011 of less than 3 trillion cubic feet.
Assuming that recovery rates averaged 10%, then the resources identified by the exploration companies would meet 25% of the UK’s gas needs for around 40 years. If recovery rates averaged 18%, as in the US, then 25% of the UK’s gas needs could be met for around 75 years.
Assuming a lower penetration of shale gas, with shale gas meeting 10% of the UK’s gas consumption, the resources identified by the exploration companies would be enough for 100 years if recovery rates averaged 10%.
The main point is that, whichever way you look at it, there is a lot of shale gas around the world, and a lot in the UK, even if we assume a relatively low recovery rate. Shale does have the potential to meet a significant portion of our natural gas consumption, both in the UK and globally. As a new report, published today, has stated, shale gas could account for a quarter of UK gas consumption in 20 years.6
2. Why are the estimates for shale gas so changeable?
It is completely true that the estimates of shale gas resources are frequently being revised upwards and, sometimes, downwards. This is not really surprising. Globally, the shale industry is still in its infancy. In the UK, for example, only a small number of exploration wells have been drilled. The more exploration drilling that is permitted, the better our picture of shale resources will be.
In the US, production is far more advanced, but estimates are still subject to change. For example, in 2011, the US Energy Information Administration estimated that the US had 827 trillion cubic feet of technically recoverable shale reserves, but has now revised that figure downwards to 482 trillion cubic feet (still a very significant figure).7 At the same time, the most recent data shows that proved reserves of natural gas have increased from 284 trillion cubic feet at the end of 2009 to 318 trillion cubic feet at the end of 2010—this increase is entirely accounted for by increases to proved reserves of shale gas, which have risen from 61 to 97 trillion cubic feet over a single year.8
It is also worth pointing out that conventional hydrocarbon resource estimates are also subject to change. As price rises incentivise companies to invest more in exploration, estimates of reserves tend to increase. It is worth remembering the many predictions over recent decades that the world would soon run out of, for example, oil—invariably, these predictions have proved to be too pessimistic.
Over the long run, as exploration increases and the hydraulic fracturing technology improves, we would expect the quantity of shale gas reserves that are economic to extract to increase.
3. What are the prospects for offshore shale gas in the UK Continental Shelf?
It is difficult to say with any certainty at the moment. The British Geological Survey has said that offshore shale gas reserves could be five–10 times higher than onshore reserves9—in other words, a big number. But it is far more difficult and expensive to extract, and at current oil and gas prices and current levels of technology, it seems to us unlikely that significant offshore shale gas development will take place. Technological development could, however, change our view of offshore shale gas prospects.
4. Should the UK consider setting up a wealth fund with the tax revenue from shale gas?
The immediate temptation would be to use any tax revenue from shale gas development to offset falling North Sea revenue to help reduce the deficit. Given the size of the deficit, that may be the best thing to do.
Long-term, though, a wealth fund earmarked to help fund pay-as-you-go pension schemes would be a better option. The UK’s long run public spending liabilities, particularly on pensions, health and other age-related spending, are very large. Meeting these commitments in an affordable way is dependent on a long run GDP growth projection that may fail to materialise. Moving from pay-as-you-go to funded provision is clearly the long-term solution, but raises the problem of one generation effectively paying twice. A wealth fund could ease this transition.
Alternatively, a wealth fund could be used to pay for much-needed infrastructure improvements, which would tend to raise the UK’s rate of growth, so making the age-related spending commitments easier to meet in the long-term.
It’s worth noting that Norway’s management of its North Sea revenues has been far superior to the UK’s, although Norway does have a far smaller population. The UK made short-term choices when North Sea production took off more than three decades ago. Now may be the time for the government to take wiser decisions.
5. What have been the effects of shale gas on the LNG industry?
And
6. Could shale gas lead to the emergence of a single, global gas market?
The simple answer to these two questions is that time will tell. If shale production is carried out at scale outside of North America, the impacts could be huge, releasing a massive amount of new supply onto global markets, leading to large price reductions. If not, the impacts will be smaller.
In the US, the biggest impact of shale on the LNG market has been to make redundant vast investments in LNG import infrastructure. LNG import terminals are now being refitted for export.
Forecasts for future exports are enormous. Cheniere alone has agreements with four global buyers to export 2 billion cubic feet a day for 20 years—equivalent to over 0.7 trillion cubic feet a year. Meanwhile nine other companies, including Freeport LNG, Gulf Coast LNG and Cameron LNG, are seeking approval to export gas. According to the US Energy Information Administration, the capacity sum of potential exports from these nine companies and Cheniere amounts to 14 billion cubic feet a day or over 5 trillion cubic feet a year10—about 1.5 times total UK annual gas consumption. The US is expected to become an LNG net exporter in 2016.11
There are a number of potential benefits from these developments, some of which we are already starting to see:
De-linking of natural gas prices from oil prices. In the US, as oil prices have risen, natural gas prices have fallen. This will start to happen elsewhere.
Reductions in Asia-Pacific natural gas prices. Pacific Basin gas prices can be as high as $16 per Million British Thermal Units, compared with around $9 in the UK and around $3 in the US. US LNG exports are likely to go to Asia, reducing prices there. Indeed, Japan is already looking to reduce the price it pays for LNG supplies.
Reduction in the pricing power of Russia, Qatar and other major gas suppliers. This year, Russia has reduced the prices it charges for natural gas to German utilities,12 and Qatar has reduced the price it charges to a major Italian utility.13 More price reductions will inevitably follow, as oil-linked gas contracts are superseded. European gas prices could start to fall.
Nevertheless, a single, global gas market may be some way off. It costs around $4–5 per Million British Thermal Units to liquefy, transport and re-gasify LNG. So, for instance, if US Henry Hub prices increase to, say, $5 per MMBTU, then US LNG would have no price advantage over the UK’s National Balancing Point.
Regional production will therefore be important. The best way for the UK (and Europe) to reduce natural gas prices is to increase its own production of shale.
7. What are the effects on investment in lower-carbon energy technologies?
The biggest driver of low-carbon energy investment is policy designed to meet carbon reduction and renewables objectives—the Renewables Obligation and the forthcoming EMR, together with the Carbon Price Floor and the EU ETS. Shale development does not in itself change these policies, so there is no reason to believe that it will affect the level of low-carbon investment.
In the US, it is noticeable that renewables development has proceeded at a rapid pace, at the same time as increasing quantities of shale gas have reached the market. Between 2006 and 2011, the share of US electricity generation from natural gas rose from 22% to 25%, and the share from renewables rose from 9% to 13%.14 The big threat to renewables investment in the US is the forthcoming expiry of the Production Tax Credit—in the US, it is also policy that has driven renewables investment.
There is no reason to see a conflict between natural gas and renewables, especially since natural gas will be an important provider of back-up power when the wind isn’t blowing. Globally, natural gas and renewables are set to be the biggest energy growth stories.
According to the International Energy Agency, provided shale development does proceed at scale outside the US, gas is projected to meet 31% of global primary energy demand growth by 2035, with renewables (including hydro and biomass) accounting for 34%.15
According to BP, natural gas will account for 31% of global energy growth by 2030, while renewables and nuclear will together account for 34% of demand growth.16
Of course, it is possible that a glut of cheap gas will spur calls to reduce the level of subsidy provided to renewables and nuclear. In that sense, shale gas could have a negative impact on low-carbon development. But again, that’s a matter for policy.
DECC’s energy and emissions projections see natural gas without CCS contributing 128 TWh of electricity generation in 2030, a fall from its 2011 level of 149 TWh, but still significant.17 At the same time, gas import dependency is expected to rise to 74% by 2030.18 Unless policy towards low-carbon energy investment changes, the biggest impact of shale gas (apart from on price) will be to slow, halt, or reverse the rise of gas imports as a proportion of the UK’s gas consumption.
8. What is the potential impact on climate change objectives of greater use of shale gas?
The question states “climate change objectives” rather than “the UK’s decarbonisation objectives”. The difference is important. Climate change is a global rather than a local problem—if China was to reduce its greenhouse gas emissions by 20%, climate change objectives would be closer to being met than if the UK was to reduce its greenhouse gas emissions by 80%. The problem is that the UK has taken too parochial a view of the climate change problem—the UK certainly needs to play its part, but the biggest impact will come from changes made in other parts of the world.
We believe that shale gas has the potential to help countries to reduce carbon emissions (and improve air quality) by complementing renewables and nuclear in replacing coal. Coal accounts for 27% of the world’s primary energy supply, but is responsible for 43% of global CO2 emissions. Natural gas, by contrast, accounts for 21% of global primary energy supply and 20% of global CO2 emissions.19 At today’s level of energy consumption, replacing coal entirely with natural gas would save around 17% of global CO2 emissions.
The potential is much higher than this. Emissions from oil used in road transport can be reduced by using natural gas vehicles (and electric cars). And in practice, coal is likely to be gradually replaced by a combination of gas, renewables and nuclear. Cheap gas will help heavy coal-using countries, such as China, to reduce their dependence on coal more quickly.
In the US, CO2 emissions have fallen by 450 million tonnes over the last five years, more than any other country. There have been a number of reasons for this, including the recession, more efficient technology, and the displacement of coal by gas and renewables in electricity generation. Over this period, as a share of US electricity, coal generation fell from 49% to 42%, while natural gas generation rose from 22% to 25% and renewable generation rose from 9% to 13%.20
Other countries can follow suit, with shale gas complementing renewables in reducing the quantity of coal used. Other challenges remain, including the need to moderate energy demand growth, but shale gas can play a part in helping the world to move to a lower-carbon energy mix.
Concluding Thoughts
It is not possibly to predict precisely the quantity of UK shale gas resources that will prove economic to extract, nor the impacts on price that shale gas development will have in the UK and globally. But if we allow development to go ahead, we will start to find out.
The big picture is that shale gas could release a large quantity of new supply onto gas markets, leading to a reduction in price. That has to be a beneficial development that, in the UK, we should be excited about. Shale will not solve all our energy problems—it is unlikely to account for even a majority of our gas usage—but it can make a major positive difference. Shale has helped to transform the US’s energy prospects—it could do the same in the UK, if we allow a properly regulated shale gas industry to develop.
