The ongoing European trepidation towards shale gas is putting Europe at an increasing economic disadvantage. The lack of energy competitiveness vis-à-vis the United States has also become the biggest concern of Europe’s industrialists, mentioned Leif Johansson, chairman of AstraZeneca and Ericsson and head of the European Round Table of Industrialists in a recent interview with the FT.
It is well known that the shale gas revolution in the U.S. has led to a massive drop in natural gas prices. From the peak in 2008, gas prices fell by over 70 percent by January 2010 and have roughly remained at that level since. This has led U.S. electricity producers to increasingly use gas-fired power rather than coal-fired power plants to supply electricity, with dramatic effects on the U.S. supply curves of electricity, as the two curves below show. One is from prior to the shale gas revolution (2005); the other from after the massive arrival of shale gas (2012).
This has been positive for the U.S. on two fronts. Firstly, natural gas is a cleaner fuel which is better for the environment. Secondly, with more competition in the market for electricity generation following the availability of shale gas, electricity prices are falling for consumers, a massive saving for the U.S. economy.
On the other hand, the preference for shale gas has left coal producers out in the cold.
In with shale, out with coal
U.S. coal producers have seen a declining demand in steam coal from the U.S. electricity sector. At the same time, they have maintained their annual production volumes. While coal imports into the U.S. have dropped dramatically, the excess coal production has needed to be stockpiled, exported or both. Currently, U.S. coal producers are banking on export markets to rid the stockpiles. A recent report from the U.S. Congress framed this issue very clearly: “One of the big questions for the [U.S. domestic coal] industry is how to penetrate the overseas market, particularly in steam coal, to compensate for declining domestic demand.”
U.S. coal producers have been successful at increasing exports and reducing imports. From 2007 to 2012, coal exports more than doubled with Europe taking about 58 percent of total exports in 2012, up from 32 percent in 2007.
This was driven by cheaper coal. The shale gas boom in the U.S. made coal less interesting to local electricity generators and it was to be expected that European electricity generators would capitalise on this “coal price revolution”. This revolution is the opposite to what is happening in the U.S. Coal had dropped from 25 percent of the total power mix in Europe in 2007 to 21 percent in 2010, but the trend reversed, starting in 2011, reaching 22 percent. In 2012, coal fired electricity output in Europe even rose by 6 percent, a greater increase than Portugal’s total electricity generation. The share of natural gas in the total power mix in Europe increased from 12 percent in 2000 to 19 percent in 2008 but had already dropped to 17 percent by 2011.
A vicious economic – and ecological – energy cycle for Europe?
In the absence of a European supply of inexpensive shale gas, the shift to coal is a rational economic decision for European power generators. The consequences of the shift, however, are detrimental on several fronts. Firstly, in spite of lower coal prices, Europe’s energy cost position relative to the U.S. will only further deteriorate. Secondly, the negative knock-on effect of relatively higher energy costs on Europe’s energy intensive industries creates further disadvantage for Europe, already handicapped by very high structural costs. Thirdly, greenhouse gas emissions, which are roughly twice as high for coal fired plants than for gas fired plants, are saddling Europe with an ecological predicament. Losing on both economic and ecological grounds is the worst outcome.
Leaving the arbitration of Europe’s energy feedstock to “market forces” is poor policy, especially if the market mechanisms are leaving Europe dangling between U.S. coal and Russian gas. Policy makers and corporate leaders should urgently rethink Europe’s energy situation before it becomes a quagmire. Developing local energy sources such as shale gas should remain on the agenda.

Towards a virtuous energy cycle in the US and a vicious cycle in the EU?
Quentin Philippe and Karel Cool
“In Europe we have the most expensive energy and we are not prepared to exploit the energy resources we have, such as shale gas. We have relatively high wage costs and we have a stagnating market,” M. Kurt Bock, CEO BASF[iii]
Shale gas remains very controversial in many European countries and the associated ecological concerns merit discussion. However, Europe’s trepidation towards shale gas is putting Europe at an increasing energy disadvantage, significantly handicapping energy intensive sectors such as petrochemicals, but it is also saddling households with higher electricity costs. A key reason is the switch of US electricity producers from coal to gas as a power source, and the increasing reliance on imported coal by European electricity producers. Beyond the ecological concerns of that choice,[iv]
Europe seems set for a vicious energy cycle while US industry is enjoying a virtuous energy cycle. This article sketches some of the key dynamics of the growing energy cost gap between the US and Europe.
Lower US natural gas prices led to a coal-to-gas switch in electricity generation
It is now very well known that the shale gas revolution in the US has led to a massive drop in natural gas prices. Figure 1 shows that from the peak in 2008, gas prices fell by over 70% by January 2010 and have roughly remained at the very low level since, driven by the abundant shale gas supply. Meanwhile, the price of steam coal used for electricity generation has remained relatively stable, as shown in Figure 2.
As coal became relatively more expensive than gas as a feedstock for making electricity, one could expect that electricity companies would increasingly use gas-fired power rather than coal fired plants to supply electricity. Figure 3 shows the power plants in the US in 2005 in increasing order of electricity production cost. This so-called “merit order” or supply curve shows the marginal cost of electricity production in $/MWh for the power plants in the US. The fuel that each plant used is color-coded and includes coal, natural gas, petroleum, nuclear and hydro & renewable fuels. Our calculations are based on data from SNL Energy and cover about 90% of total US electricity generating capacity.[vii],[viii]
Figure 3 shows that before the massive arrival of shale gas in the US, coal was by far the cheapest and preferred fuel to generate electricity: the average coal fired power plant had half the marginal cost of the natural gas plant, making the use of coal in the US an easy choice for electricity companies.
Figure 4 shows the merit order curve for electricity generation in 2012, after shale gas became abundant. It shows the dramatic shift in the choice of gas over coal. Most gas-fired capacity is now as cost efficient as coal-fired capacity, and in several instances is more cost efficient. A second effect of the abundance of shale gas is the drop in electricity costs. Whereas in 2005, only 55% of capacity had a marginal cost below $50/MWh, this increased by 2012 to about 82%, potentially creating lower electricity costs for a large share of the US economy.
Short-term margins from coal-based electricity have dropped substantially
The increase in the supply of natural gas to produce electricity may be expected to lead to a drop in electricity prices (assuming the supply of other low cost sources of power remain available). With more competition in the market for electricity generation following the massive increase of shale gas, one would also expect lower margins for electricity generators.
The evolution of margins for electricity producers is also remarkable. The difference between the market clearing power price and the power cost of production for a coal-fired plant is called the dark spread; the same for a gas-fired plant is called the spark spread. Figure 5 shows that the gross margins for coal-fired plants more than halved in the 2005-2009 period.[x]
Clearly, electricity users were the big winners from the increasing cost efficiency of the US electricity sector.[xi]
US coal manufacturers maintain production and look to export more coal
US coal producers thus have seen a declining demand in steam coal from the US electricity sector, certainly until 2013 as can be seen on Figure 7. While coal imports into the US dropped dramatically, the excess coal production needed to be stockpiled, exported or both. Figure shows that US coal producers decided to maintain annual production volumes, banking on export markets to idle the stockpiles. A recent report of US Congress framed the issue very clearly: “One of the big questions for the [US domestic coal] industry is how to penetrate the overseas market, particularly in steam coal, to compensate for declining domestic demand".[xv]
Figure 9 shows how successful US coal producers have been in increasing exports and reducing imports. From 2007 to 2012, coal exports more than doubled with Europe taking about 58% of total exports in 2012, up from 32% in 2007. Meanwhile imports into the US crumbled from about 35 Mt in 2007 to about 8 Mt in 2012. Of that, Europe represented 1-2%.
A shale gas revolution in the US and a steam coal revolution in Europe?
The shale gas boom in the US may have generated a more efficient US gas sector and lower electricity prices for the US economy; it also contributed to a drop in coal prices in Europe. Figure 10 shows the precipitous fall in coal prices in Europe– as represented by the McCloskey North West Europe steam coal marker price - from over $120/ton in 2011 to about 85$/ton early 2014. It is to be expected that European electricity generators would capitalize on this “coal price revolution.” Indeed, after seeing a drop in coal as fuel for electricity generation in Europe[xvii] from 25% of the total power mix in 2007 to 21% in 2010, the trend inversed, starting in 2011. In 2012, coal-fired electricity output in Europe even rose by 6%, an increase greater than Portugal’s total electricity generation. In contrast, the share of natural gas in the total power mix in Europe increased from 12% in 2000 to over 19% in 2008 but had already dropped to 17% by 2011.
A vicious economic – and ecological -- energy cycle for Europe?
In the absence of a European supply of inexpensive shale gas -- or another competitive energy source --, the shift to coal is a rational economic decision for the power generators. The consequences of the shift, however, are detrimental on several fronts. In spite of the lower coal prices, Europe’s energy cost position relative the US will only further deteriorate. The negative knock-on effect of relatively higher energy costs on Europe’s energy intensive industries creates further disadvantage for Europe, already handicapped by very high structural costs [see Why Europe needs shale gas]. Also, greenhouse gas emissions which are roughly twice as high for coal-fired plants than for gas-fired plants, are saddling Europe with an ecological predicament.[xx]
Losing on both economic and ecological grounds is the worst of all worlds. Leaving the arbitration of Europe’s energy feedstock to “market forces” is poor policy, especially if the market mechanisms are leaving Europe dangling between US coal and Russian gas. Policy makers and corporate leaders should urgently rethink Europe’s energy situation before it becomes a quagmire. Developing local energy sources such as shale gas should remain on the agenda.

The CAPP price – as shown on Figure 2 – is the price for coal with an energy content of 12,500 Btu/lb (British Thermal Unit per pound). We use the conversion factor: 1 kilocalorie/kilogram = 1.79879622 Btu/pound. Hence, the energy content of the McCloskey NWE steam coal is around 10,800 Btu/lb.

So you want Europe to switch to an energy source that according to your own company will only be able to provide 6% of our gas consumption sometime after 2025 (Russia provides 30%, now) for a much higher price per cubic meter? If we want to get rid of coal and lower our energybill shalegas clearly will not work.

The solution to CO2 emissions and the dependence of EU countries on the 30% need for imported fossil-fuels may be solved by implementation of newly proven technology at Regensburg University in Bavaria which converts all CO2 emissions into methane CH4. I invented the tech after 6 hard years’ work. The hurdle is bringing this tech to the attention of those who have the resources and power to implement it.
For about 100 years scientists battled with electrochemical pathways which are just too energy intensive to be viable (electrolysis). My system uses metabolic energy from methanogens with minimal electricity input.
The economic benefits for the western world would also follow.
