Do you think that GTL has a significant part to play in energy production or pollution reduction?

Gas-to-Liquids (GTL)

GTL developed from the Fischer-Tropsch (F-T) technology created in Germany in the 1920's. Germany and Japan both used F-T during the Second World War. After the war South Africa used coal based F-T technology. GTL can create liquid hydrocarbon fuels from gas, biomass, coal and other feedstocks. There are high (which produces petrol (gasoline) and gasoil) and low temperature versions. The low temperature version uses cobalt. Shell has had a plant in Malaysia since 1993. It is this plant that will be scaled up for Qatar. BP has a GTL test facility in Alaska. Other major oil companies have plants or plans for plants.

Gas-to-Liquids (GTL) can be used to convert natural gas to diesel, resulting in a diesel that produces virtually no sulphur (or aromatics using the low temperature version) during production, and reduced carbon monoxide, particulates, NOx and hydrocarbons when used as a fuel. As well as fuel for transport, GTL can produce naphtha for chemical feedstocks, paraffin and lubricant base oils.

For countries with substantial natural gas reserves, GTL affords an alternative or supplement to Liquefied Natural Gas (LNG) and pipelines (natural gas is four times more expensive to transport than oil). As GTL needs low cost natural gas to be economical, it is ideally suited to remote sources of gas which might not otherwise be worth extracting.

Diesel From Natural Gas Could Cut Smog

Qatar plans to use gas-to-liquids (GTL) reactors to convert natural gas into clean diesel fuel next year. The fuel should have far less pollutants. It still produces carbon dioxide though, so it won't help countries using the technology to meet their Kyoto Protocol targets. Do you think your country should use GTL?
