New Form of Ice to Store Energy
Marex
BY MarEx 2014-12-14 16:08:30
The discovery of a new form of ice could lead to an improved understanding of our planet’s geology, potentially helping to unlock new solutions in the production, transportation and storage of energy. Ice XVI, the least dense of all known forms of ice, has a highly symmetric cage-like structure that can trap gaseous molecules to form compounds known as clathrates or gas hydrates.
Such clathrates are now known to store enormous quantities of methane and other gases in the permafrost as well as in vast sediment layers hundreds of metres deep at the bottom of the ocean floor. Their potential decomposition could therefore have significant consequences for our planet, making anSeguir leyendo

Jones Act renaissance
IHS Maritime’s Greg Miller explains why US yards see stronger order levels in the tanker, container, and offshore sectors
Three external drivers have converged, pushing production of ships for the United States’ protected Jones Act trades to unusually high levels.
The first factor is surging domestic oil production, which creates a greater need to transport petroleum products and crude in coastwise trades. Such cargoes must be carried aboard US-built tankers and barges.
Second, the daunting requirement that 0.1% sulphur bunker fuel be used within the North American Emission Control Area (ECA), which extends 370km off US and Canadian , comes into effect 1 January 2015. For operators of Jones Act container ships and product tankers, andSeguir leyendo
