How about this little tid-bit-----
Could coal replace oil?
At current oil prices, one answer to the evolving shortage of liquid fuels is coal liquefaction, HSBC bank suggests.
The CTL (coal-to-liquids) technology is well-established. It was originally invented in Germany in the 1920s and developed there and in the US in the 1930s. In the Third Reich it was used to make up to 600,000 barrels a day of petrol and avgas during the Second World War.
The technology was improved greatly in South Africa in the apartheid years to reduce dependence on imported oil. I have fond memories of researching and writing about the giant Sasol enterprise in 1964 when making my reputation as a young financial journalist. I still have a copy of my Earth, Air, Fire and Water study, which for the first time explained the complex processes to the public in laymans terms.
Today there are three CTL plants in what is now democratic South Africa, converting coal into 150,000 barrels a day (equal to the output of a medium-sized oilfield). In addition to petrol, diesel and avgas, the process produces a wide range of by-products such as petrochemicals, waxes, feedstocks for plastics manufacture, and fuel gas.
While its forecast that the world will run short of conventional oil within a century, with most of the remaining large deposits in politically unstable regions, there is little recognition that coal is an abundant substitute. Enough for more than a thousand years.
The US has the worlds largest coal deposits, with 268 billion tons of recoverable reserves. HSBC says that at a standard conversion rate of two barrels of synthetic fuels from one ton of coal, those reserves are equivalent to the 20 times the nations current crude oil reserves.
At capital costs of $700 million for capacity of 10,000 barrels/day and a 30-year life, operating costs of $15/barrel and current coal costs, breakeven for a coal-to-liquids plant in the US would be in the range $39-44 a barrel, assuming no tax incentives.
However, the new Highway Act provides a subsidy of $21 a barrel for commercial-scale CTL projects. Taking that into account, with oil at $50 a barrel (that is, well below current prices around $70), the internal rate of return on such a project would be in the mouth-watering range 22-25 per cent.
It would also be environmentally friendly, as the technology converts dirty coal into ultra-clean synthetic diesel and jet fuel that can be used in current engines without adaptation. And the fuels are easily transportable and marketable, as they are compatible with existing petro-fuel distribution infrastructure (unlike ethanol-blended petrol, bio-diesel and more radical alternative fuels).
HSBC suggests that beneficiaries of CTL development in the US could include mining companies such as Peabody Energy and Arch Coal, and providers of proprietary technologies such as GEA Group (Lurgi), GE Energy, Royal Dutch Shell, ConocoPhillips, Rentech, Syntroleum and South Africas Sasol. The latter, now listed in New York as well as Johannesburg, is becoming a global giant in synthetic fuel projects (see later article about gas-to-liquids).
China, which like the US has huge coal reserves but increasing dependence on imported oil, is adopting the CTL solution. Its first plant will start production next year.
State-owned Shenhua, the biggest coal mining company, in association with Sasol and Shell, wants to build additional plants to make liquid fuels equivalent to 10 million tons of crude oil a year by 2010, at a cost of about $10 billion, and 30 million tons by 2020.
HSBC says the typical final product mix from Fischer-Tropsch synthesis contains between 70 and 80 per cent diesel fuel and 10 to 20 per cent jet fuel, with chemical and burning qualities superior to
their counterparts derived from petroleum through refining.
The world isnt going to run out of oil while theres all that coal that can be turned into liquid fuels.
