Charting the Future of Methane Hydrate Research in the by National Research Council, Division on Earth and Life

By National Research Council, Division on Earth and Life Studies, Board on Earth Sciences and Resources, Ocean Studies Board, Committee to Review the Activities Authorized under the Methane Hydrate Research and Development Act of 2000

Methane hydrate is a usual kind of clathrate - a chemical substance during which one molecule varieties a lattice round a 'guest' molecule with chemical bonding. during this clathrate, the visitor molecule is methane and the lattice is shaped by way of water to shape an ice-like sturdy. Methane hydrate has develop into the point of interest of overseas realization due to the gigantic power for human use world wide. If methane may be made out of hydrate, an inexpensive assumption on condition that there are not any seen technical or engineering roadblocks to advertisement creation, the nation's traditional fuel strength offer may be prolonged for a few years to come.This record reports the dept of Energy's (DOE) Methane Hydrate examine and improvement application, the venture choice approach, and initiatives funded so far. It makes tips on how the DOE software will be enhanced. Key thoughts contain focusing DOE application emphasis and study in 7 precedence components; incorporating better clinical oversight within the choice, initiation, tracking, and overview of significant initiatives funded via the DOE; strengthening DOE's contribution to schooling and coaching via investment of fellowships, and supplying venture candidates with a suite of directions and guidance outlining specifications for well timed and whole disclosure of venture effects and results of noncompliance.

Electrochemical Water Processing

Even if many of the Earth’s floor is roofed with water, such a lot of it isn't without delay usable for human intake or purposes. because the inhabitants raises and our basic type of residing criteria raise, the significance useable water is turning into acute. This booklet addresses this factor with ways to treating water resources that require removing of undesirable or dissolved ingredients.

Industrial Gas Flaring Practices

This quantity tackles for the 1st time in many years the world's fuel flaring practices, a tricky, hot-button factor of our time, whose effects are just simply starting to be understood. The e-book examines either the technical and environmental facets of fuel flaring, highlights diversified flare designs, and provides real-world case experiences illustrating the correct use of fuel flaring and the way to prevent polluting flaring occasions.

Natural Gas Processing. Technology and Engineering Design

Traditional fuel is taken into account the dominant world wide bridge among fossil fuels of at the present time and destiny assets of the following day. due to the hot shale increase in North the USA, ordinary gasoline is in a surplus and speedy turning into a tremendous overseas commodity. remain present with traditional and now unconventional fuel criteria and techniques with normal fuel Processing: know-how and Engineering layout.

Example text

The proposals are subjected to external merit review and internal NETL review for relevance to program needs. An external expert panel with members from industry, academia, other federal agencies, and national labs subsequently reviews the proposals considered relevant. 8 million have received funding using this mechanism (DOE, 2004a). A REVIEW OF PROJECTS TO DATE 47 Other nonfederal government procurements include fixed-price contracts and small purchase orders. Fixed-price contracts are used when no other alternatives are available to perform unique tasks requiring timely action.

38 CHARTING THE FUTURE OF METHANE HYDRATE RESEARCH The baseline seismic velocity in the absence of gas hydrate, needed to calibrate models, is also generally not known. , 1999). Moreover, even when geophysical estimates of gas hydrate content have been compared to drilling results, in situ estimates have uncertainties due to limitations of the tools available to estimate the amount of gas hydrate in boreholes and recovered cores. The imperfect knowledge of the distribution of gas hydrate will be much improved with the widespread and routine use of pressure coring techniques that enable direct measurement of the concentration of hydrate in sediments.

DOE’s participation in Mallik II (2002) and ODP Leg 204 is discussed in Chapter 3. , 2004). , 2003) WHY STUDY GAS HYDRATE? , Hesse and Harrison, 1981; Ussler and Paull, 2001). For logistical reasons, these techniques sample only a small percent of the total core and provide measurements that are spaced meters to tens of meters apart. Recently, these robust but spatially incomplete measurements have been supplemented by infrared core scans, which can image all cores. , 2003, 2004). Because core recovery is often incomplete, geophysical logging methods are needed to sample the entire borehole.
