What are the disadvantages of using gas hydrates as energy resources?
hydrates have a major disadvantage since they evaporates quickly under normal surface pressure and temperature; this is a major disadvantage to using as a source of energy.
What problems do hydrates cause?
Conversely, gas hydrates are known as a foremost problem in oil & gas pipelines, which can cause flow pressure drop due to deposits, plug the flow lines and offshore production facilities and even turn into pipeline explosions (8) .
What are the major challenges in gas hydrate exploitation?
High-pressure drawdown, hydrate dissociation induced strength loss, and sand migration are critical challenges. Deep offshore technologies developed for conventional reservoirs may be promising for NGH exploitation.
What are the benefits of gas hydrates?
Hydrate can serve as a sustainable energy resource and a means of storing and transporting natural gas from one end to the other. This will create an effective and efficient alternative for bulk gas transportation and storage for future use of the gas.
What are gas hydrates quizlet?
What are gas hydrates? crystalline solid ice-like compounds. Within these structures are small gas molecules trapped inside of a cage of water molecules.
Is gas hydrates renewable or nonrenewable?
Answer and Explanation: Methane hydrate is a non-renewable resource. This is because the methane trapped in the ice is a fossil fuel, created over millions of years of heat…
Why are hydrates bad for oil gas?
Gas hydrates are also a risk, representing a hazard to oil and gas drilling and production. If gas hydrates dissociate suddenly and release expanded gas during offshore drilling, they could disrupt marine sediments and compromise pipelines and production equipment.
What is a hazard associated with the potential mining and use of gas hydrates?
The possibility that hydrate mining could generate submarine landslides on steep continental slopes has also been discussed. Like avalanches in mountainous regions, submarine landslides are natural events. They occur on continental margins where thick layers of soft sediment have accumulated, such as near river mouths.
What is a potential drawback of mining methane hydrate and using it as an energy source?
The problem, however, is accessing the hydrates. Quite apart from reaching them at the bottom of deep ocean shelves, not to mention operating at low temperatures and extremely high pressure, there is the potentially serious issue of destabilising the seabed, which can lead to submarine landslides.
Is methane a hydrate?
Methane hydrate is a class of clathrate, composed of water and low molecular weight gases, mainly methane, which forms under low temperature, high pressure, and appropriate methane concentrations.
What is a problem with methane hydrate?
If the methane hydrates decompose, the stability of the sea floor is reduced due to the missing cement and the possible generation of excess pore pressure. In the worst case, large parts of continental margins fail. The resulting submarine landslides might cause severe tsunamis.
What is gas hydrate?
Gas hydrates are ice-like crystalline minerals that form when low molecular weight gas (such as methane, ethane, or carbon dioxide) combines with water and freezes into a solid under low temperature and moderate pressure conditions.
How does mining for natural gas affect the ocean?
Unconventional oil and gas development also poses contamination risks to surface waters through spills and leaks of chemical additives, spills and leaks of diesel or other fluids from equipment on-site, and leaks of wastewater from facilities for storage, treatment, and disposal.
What are the disadvantages of methane gas?
Disadvantages: It is a main contributor to global warming. It is very dangerous to the human body, high enough concentrations in the air can result in suffocation of air breathing creatures.
What are methane hydrates and why are they of concern?
Some believe there is enough methane in the form of hydrates—methane locked in ice—to supply energy for hundreds, maybe thousands, of years. Methane hydrates, a promising natural gas resource, are believed to reside throughout the globe in sea-floor sediments and permafrost.
Are methane hydrates difficult to extract?
According to the Department of Energy, methane hydrates are abundant on the seafloor and under permafrost, and they contain “perhaps more organic carbon that all the world's oil, gas, and coal combined.” Such vast reserves of fossil fuels are untapped because of how difficult it is to extract them.

What is a disadvantage of using natural gas?
Even though natural gas is easier to store and transport than other fossil fuels and renewables, it has one big storage disadvantage. Its volume happens to be four times as big as petrol's. Because of this, natural gas storage is much more expensive since more storage space is needed.
