Methane hydrates \u2014 gas molecules trapped within a lattice of ice<\/a>
\u2014 could contain more energy than all other known fossil fuels
combined. That is, if folks figure out how to produce volumes of
methane from hydrate beyond a few small-scale field experiments.<\/p>\n<\/p>\n

Until then, the testing will continue. ConocoPhillips<\/strong>, the Energy Department<\/strong> and Japan Oil, Gas and Metals National Corp<\/strong>. are conducting the latest round of field experiments<\/a>, which will focus on a production method that could create an innovative way of storing carbon dioxide.<\/p>\n
<\/p>\n
During the initial field trial set to begin in January 2012, carbon
dioxide will be injected into the methane hydrate-bearing sandstone
formations, which can be located more than 1,500 feet beneath the ocean
floor. Carbon dioxide molecules will be swapped for methane molecules,
and aims to achieve two goals: release the methane gas and permanently
store the carbon dioxide in the formation. This field experiment will be
an extension of earlier successful tests of the technology conducted by
ConocoPhillips and its partners in a laboratory setting, the DOE said.<\/p>\n<\/p>\n
The tests will use the \u201cI\u0121<\/span>nik Sikumi\u201d (I\u00f1upiaq for
\u201cfire in the ice\u201d) gas hydrate field trial well that was installed in
Alaska\u2019s Prudhoe Bay region by ConocoPhillips and the Office of Fossil
Energy\u2019s National Energy Technology Laboratory earlier this year.<\/span>
The team will spend another month evaluating an alternative method of
methane production called depressurization, which was successfully
demonstrated during a one-week test in a different location by Japan and
Canada back in 2008.<\/p>\nPhoto: Wikicommons; DOE<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"
