Experiments, both in the field and laboratory, are very expensive. Models of methane production from hydrate can save substantial expense of time, effort, and capital. This section of Chapter 7 gives guidelines from the models for hydrate dissociation. 

In the mid-term, sequestration pilot testing will develop options for direct and indirect sequestration. The direct options involve the capture of C02 at the power plant before it enters the atmosphere coupled with "value-added" sequestration, such as using COz in enhanced oil recovery (EOR) operation and in methane production from deep unmineable coal seams. "Indirect" sequestration involves research on means of integrating fossil fuel production and use with terrestrial sequestration and enhanced ocean storage of carbon.

Methanol and methane production from C02 was observed when aqueous suspension of ZnO was irradiated with visible light [89], Experiments with ZnS carried out by Yoneyama et al. [90,91] or recently by Martin et al. [92] showed high efficiencies in carbon dioxide reduction to formate.

Figure 4 The and 8 H isotopic values for methane gas found dissolved in saline groundwaters from several sites on the Canadian and Fennoscandian Shields (samples for each area are circled). These are compared to the bacterial and thermogenic ranges of Schoell (1988). and Bp are the ranges as outlined by the boxes of bacterial methane production from CO2 reduction and acetate fermentation, respectively (Collar et al. 1993b) (reproduced by permission of Elsevier from Geochim. Cosmochim. Acta, 1993, 57, 5087-5097).

Bechamp (15) in 1867 was the first to describe methane production from a simple fermentation product, ethanol, and to attribute it to a microbial fermentation. The second product he found to be formed from ethanol was caproate, now known to be produced by Clostridium kluyveri (4). Thus, carbon-carbon bonds are not only destroyed early in the fermentation chain, they can also be reductively synthesized if the reaction is paired with the energy yielding oxidation of another substrate (c/. initial fermentations of acetate and ethanol and also of H2, Figure 1). Several successive fermentations may then be required to convert these products to methane and CO2.
