Stability and transformation in the electricity system 99 technologies, especially gasification of coal, and techniques to reduce the negative environmental impacts coal-fired power plants, such as desulphurization. Research efforts on coal became second in size next to nuclear research. Coal gasification technology 22 was developed by several oil companies 23 , such as Shell, Texaco and British gas, as a future alternative to oil as a source for its products and some test plants were operating in the USA and Germany. Because of the environmental problems associated with conventional coal-fired power plants the electricity sector started to explore the potential of gasification. Coal gasification in combination with steam and gas turbines (KV/STEG) was expected to give similar emissions of NOx and SO2. After two years of exploration of the technological options, SEP decided, on technical grounds, to use the technology developed by Shell (Zon, 2000). Coal gasification was implemented in the nineties at a 250 MWe demonstration plant in Buggenum, total costs of 850 million guilders were financed by the SEP. In the demonstration phase some major problems occurred, mainly in the conventional part of the plant: the gas turbine. Characteristics of the synthesis gas called for adaptations in the gas turbine. The producer of the gas turbine, Siemens, invested tens of million guilders to improve its operation. The Buggenum plant became operational in the middle of the nineties as the first and largest coal gasification plant for electricity generation in the world at that time was considered technologically unique (Böttcher, 1999). After a demonstration period until the end of 1997 the power plant became part of electricity production by the SEP. In the transition period to a liberalised market, it became clear that the plant was not competitive due to the high investment costs 24 . With the dismantling of the SEP the plant became labelled among the stranded costs, burdens that were to be distributed among power producers and 22 Gasification is the process of reacting a heated carbon source – whether biomass, coal, or even low qualitiy grades like lignite, with oxygen and steam to produce syngas. Syngas – a mixture of carbon monoxide and hydrogen – can also be produced from a range of other feedstocks including tar sand, oil and natural gas. Syngas is used for electricity generation as well as to make base chemicals for the petrochemicals industry (Source: website of Shell, http://www.shell.com/royal-en/content/0,5028,25544-51272,00.html). 23 For example, Shell had invested several hundreds of millions US $ in the technique at its laboratory in Amsterdam (KSLA), and in a test facility in Hamburg. Texaco had a facility in operation in Coolwater, USA, for the production of hydrogen, with use of around 100 tonnes of coal per day. As gas prices were expected to rise in future years because of its more acute finiteness as compared to oil and coal, oil companies saw opportunities to sell the synthesis gas produced by gasificiation. This gas could in the long term also replace oil as the basis for most of their products (Roggen, 2000; Zon, 2000). 24 According to the former director of Demkolec, KV/STEG could be competitive to conventional coal-fired power plants with a capacity above 600 MW. A plant of that size would require an investment of around 1250,- Euro per kW capacity (Zon, 2000).

Nevertheless, many in the electricity world still see coal gasification as a major future technological option with a large potential market in countries that depend largely on coal as an energy source, for example Shell has already licensed the technology to China 26 (Böttcher, 1999; Zon, 2000). An additional characteristic of gasification is that in the production of synthesis gas it is relatively easy to isolate CO2. In a new application of gasification of oil residual at a plant of Shell in Pernis, CO2 is extracted and distributed to horticulture companies 27 while the syngas is used for petrochemical purposes. Overall conclusions regarding the re-emergence of coal are: – With the closure of the nuclear energy route, coal became the most logical alternative to gas in the perspective of the electricity sector and government; – Coal clean-up technology and clean coal technology has been strongly stimulated by government funding and by the electricity sector; – Increasing environmental concerns and the second environmental wave (NEPP in 1989) steadily deteriorated the government attitude towards coal, the climate problem accelerated this due to the high CO2 contents of coal; – Coal gasification, technologically developed by oil companies, was seen by the electricity sector as a promising alternative because it could provide a cheap long-term source, has a relative good environmental profile and can approach efficiencies of the most efficient power plants; – The technological success of the Buggenum plant was also due to the strategic interests seen by a leading gas turbine producer that participated in the project; – The electricity sector, through its collective organisation SEP, was able to finance the construction of the Buggenum plant by transferring high investment costs to consumers, the breakdown of SEP due to ongoing privatisation has made the plant unprofitable due to high capital costs; – Experience with coal gasification has also led to further application of the technique, for example for oil residue (which is commercially applied), and further R&D on potential application with biomass; – While the Buggenum plant was seen as one of the most advanced examples of energy technology; it became economically labelled under 25 SEP was dissolved due to liberalisation and privatisation and the Buggenum plant has been sold to NUON who uses it as a biomass gasification plant. 26 According to Böttcher (1999: 22) also in Japan coal gasification is seen as an important medium term option in which various gaseous products can be transported (for example through co-operation with China) to be used both for energy supply and as input for chemical processes. 27 CO2 levering aan kassen bijna rond, in Nieuwsblad Stromen, August 18, 2000.

government 25 . Never<strong>the</strong>less, many in <strong>the</strong> electricity world still see coal<br />

gasification as a major future technological option with a large potential<br />

market in countries that depend largely on coal as an energy source, for<br />

example Shell has already licensed <strong>the</strong> technology <strong>to</strong> China 26 (Böttcher,<br />

1999; Zon, 2000). An additional characteristic of gasification is that in <strong>the</strong><br />

production of syn<strong>the</strong>sis gas it is relatively easy <strong>to</strong> isolate CO2. In a new<br />

application of gasification of oil residual at a plant of Shell in Pernis, CO2 is<br />

extracted <strong>and</strong> distributed <strong>to</strong> horticulture companies 27 while <strong>the</strong> syngas is used<br />

for petrochemical purposes.<br />

Overall conclusions regarding <strong>the</strong> re-emergence of coal are:<br />

– With <strong>the</strong> closure of <strong>the</strong> nuclear energy route, coal became <strong>the</strong> most<br />

logical alternative <strong>to</strong> gas in <strong>the</strong> perspective of <strong>the</strong> electricity sec<strong>to</strong>r <strong>and</strong><br />

government;<br />

– Coal clean-up technology <strong>and</strong> clean coal technology has been strongly<br />

stimulated by government funding <strong>and</strong> by <strong>the</strong> electricity sec<strong>to</strong>r;<br />

– Increasing environmental concerns <strong>and</strong> <strong>the</strong> second environmental wave<br />

(NEPP in 1989) steadily deteriorated <strong>the</strong> government attitude <strong>to</strong>wards<br />

coal, <strong>the</strong> climate problem accelerated this due <strong>to</strong> <strong>the</strong> high CO2 contents<br />

of coal;<br />

– Coal gasification, technologically developed by oil companies, was seen<br />

by <strong>the</strong> electricity sec<strong>to</strong>r as a promising alternative because it could<br />

provide a cheap long-term source, has a relative good environmental<br />

profile <strong>and</strong> can approach efficiencies of <strong>the</strong> most efficient power plants;<br />

– The technological success of <strong>the</strong> Buggenum plant was also due <strong>to</strong> <strong>the</strong><br />

strategic interests seen by a leading gas turbine producer that participated<br />

in <strong>the</strong> project;<br />

– The electricity sec<strong>to</strong>r, through its collective organisation SEP, was able <strong>to</strong><br />

finance <strong>the</strong> construction of <strong>the</strong> Buggenum plant by transferring high<br />

investment costs <strong>to</strong> consumers, <strong>the</strong> breakdown of SEP due <strong>to</strong> ongoing<br />

privatisation has made <strong>the</strong> plant unprofitable due <strong>to</strong> high capital costs;<br />

– Experience with coal gasification has also led <strong>to</strong> fur<strong>the</strong>r application of <strong>the</strong><br />

technique, for example for oil residue (which is commercially applied),<br />

<strong>and</strong> fur<strong>the</strong>r R&D on potential application with biomass;<br />

– While <strong>the</strong> Buggenum plant was seen as one of <strong>the</strong> most advanced<br />

examples of energy technology; it became economically labelled under<br />

25 SEP was dissolved due <strong>to</strong> liberalisation <strong>and</strong> privatisation <strong>and</strong> <strong>the</strong> Buggenum plant has been<br />

sold <strong>to</strong> NUON who uses it as a biomass gasification plant.<br />

26 According <strong>to</strong> Böttcher (1999: 22) also in Japan coal gasification is seen as an important<br />

medium term option in which various gaseous products can be transported (for example<br />

through co-operation with China) <strong>to</strong> be used both for energy supply <strong>and</strong> as input for<br />

chemical processes.<br />
