Prometheus Energy Co. revealed it has begun construction on its liquid natural gas (LNG) production plant in Lisbon, Utah and expects commercial production of 12,000 gallons of LNG per day to start in the second quarter of 2008.

The company also said it has obtained its building permit for the 10,000 gallon per day facility at the Krupinski Coal Mine in Poland and expects to break ground on that project by the end of March or earlier as weather permits.

The alternative and renewable energy company said the project's second phase will begin later this year and will increase plant output to 22,000 gallons per day.
