Gas Hydrate Data

Gas hydrates, especially methane hydrates, are one of the major carbon reservoirs available on earth. Gas hydrate reservoirs have come into the focus of scientific and technological developments because they are, optionally, a major source for a future energy supply and a key element of the global carbon balance and have had great influence on the climate during the history of geology.

The amount of gases stored in naturally occurring gas hydrates is estimated to be larger than the currently known gas, oil and coal resources. These hydrates could be extracted to solve the energy problems of the industrialized world for centuries.

Gas hydrate exploration is done today in a significant amount but there are severe problems and risks with extracting and transporting the gas hydrates.

The Dortmund Data Bank now provides a strongly growing collection of thermophysical data published in recent years which could help solving the major safety and process development issues.
