GILLETTE — The future of a demonstration coal gasification project in the Powder River Basin is uncertain because it hasn't gotten approval from Wyoming regulators yet.
Australia-based Linc Energy began working with the state to develop the underground project near Wright in 2012. It would use technology from its Queensland gasifier to ignite coal underground and produce a synthetic gas.
However, Linc is also pursuing similar proposals in South Africa, Poland and Russia. Spokesman Paul Ludwig said which one will be developed next depends on which one advances first as well as its economics.
Linc expected Wyoming permitting to be done by the first half of this year. Regulators say the permit should be issued for public review in the next three months.
