Gas Hydrates – Theory, Production, Applications, Reference & Resources
Gas Hydrate: What is it?: A gas hydrate is a crystalline solid; its building blocks consist of a gas molecule surrounded by a cage of water molecules. Thus it is similar to ice, except that the crystalline structure is stabilized by the guest gas molecule within the cage of water molecules. Many gases have molecular sizes suitable to form hydrate, including such naturally occurring gases as carbon dioxide, hydrogen sulfide, and several low-carbon-number hydrocarbons, but most marine gas hydrates that have been analyzed are methane hydrates.
Gas Hydrate Studies - A Part Of The Geophysics Group: Gas Hydrate can be studied in the laboratory, where a machine is used to create the proper pressure and temperature conditions for hydrate formation, or it can be studied in situ using seismic data collected aboard ships and geophysical models.

Gas Hydrates – Fuel of the Future: Description of Gas hydrates. what they are, why research about them is important.
An Introduction to Gas Hydrates: The purpose of this page is to introduce hydrates and to stimulate the visitor's interest in the subject.
Gas Hydrates: Under the enormous pressures and cold temperatures at the bottom of the ocean, methane gas dissolves. The molecules of methane become locked in a cage of water molecules to form crystals. These crystals look like ice, and they cement together the ocean sediments. In some places a solid layer of crystals—called methane hydrate—extends from the sea floor down hundreds of meters.
Gas Hydrate Studies at UTIG: The enormous potential of gas hydrates as a fuel source and their role as a "greenhouse" agent if freed into the atmosphere have generated huge interests among the scientific community and industry.
Gas Hydrates Concepts
Control of Gas Hydrate Formation Using Surfactant Systems: Underlying Concepts and New Applications: Some new approaches to the rapid formation of gas hydrates using surfactant systems that form reverse micelles.
How Gas Hydrates are Produced
Method of producing gas hydrate in two or more hydrate forming regions: A process for producing natural gas hydrate comprises three states (i), (ii), and (iii). State (i) comprises three pressure vessels (A1, A2, and A3), stage (ii) two pressure vessels (A4 and A5), and stage (iii) the pressure vessel (A6). The conditions of temperature and pressure in the pressure vessels are such that the gas hydrate is formed in the vessels.
Natural Gas May Be Extractable From Ocean Gas Hydrates: For the first time, an international research program involving the Department of the Interior's U.S. Geological Survey has proven that it is technically feasible to produce gas from gas hydrates. Gas hydrates are a naturally occurring "ice-like" combination of natural gas and water that have the potential to be a significant new source of energy from the world's oceans and polar regions.
Gas Hydrates latest
Methane hydrates: Methane hydrate isn’t a familiar term to most, but it is gaining popularity in the energy sector. In the realm of energy R&D, methane hydrates are being evaluated as a potential fuel for the future. Some believe there is enough methane in the form of hydrates—methane locked in ice—to supply energy for hundreds, maybe thousands, of years.
Gas (Methane) Hydrates -- A New Frontier: Hydrates store immense amounts of methane, with major implications for energy resources and climate, but the natural controls on hydrates and their impacts on the environment are very poorly understood.
Natural Gas Hydrates May Help Fuel the Future: Gas hydrates – natural gas and water frozen together into a solid substance – are common in arctic permafrost regions and in sediments in the ocean's deep waters. Research is now underway to better understand this vast, untapped resource: how natural gas hydrates form, where they are located and how they could be used as a future source of natural gas.
Gas Hydrates as a Future Energy Resource: Research coring and seismic programs carried out by the Ocean Drilling Program, government agencies and several industry consortia have significantly improved our understanding of how gas hydrates occur in nature and have verified the existence of highly concentrated gas hydrate accumulations at several locations. Hydrates are found widely dispersed in permafrost regions and beneath the sea in sediments of outer continental margins
Gas Hydrates: Challenges for the Future : This volume helps to answer the dual questions of how gas and oil production is affected by hydrate formation and prevention (of immediate and critical interest to current energy suppliers) and how hydrates might serve as a clean future energy supply.

Gas Hydrates Invention
Gas Hydrate Inhibitors: The invention relates to methods and compositions for inhibiting the formation of hydrocarbon hydrates, and most particularly relates, in one non-limiting embodiment, to methods and compositions for inhibiting the formation of hydrocarbon hydrates during the production of oil and gas.

Alaska Science Forum: In addition to the petroleum and free natural gas found on Alaska's North Slope, there is the possibility there of another large and, as yet, untapped energy source. This resource is the substance called natural gas hydrates.
FBPs, soils, gas hydrates and geothermal reservoir modeling: This site is about gas hydrates dissociation and formation in gas fields (a short version of the paper was published in Annals of the New York Academy of Sciences, 2000, V. 912, p.428-436.

About Oilgae - Oilgae - Oil & Biodiesel from Algae
has a focus on biodiesel production from algae while also discussing
alternative energy in general. Algae present an exciting possibility as a
feedstock for biodiesel, and when you realise that oil was originally
formed from algae - among others - you think "Hey! Why not oil
again from algae!"
