Description
Technical Field
The invention relates to a wind power generation method for exploiting a seabed surface exposed combustible ice mineral methane generation device.
Background
With the huge consumption of resources, people face the huge crisis of resources in particular in the beginning of the 21 st century, the crude oil import in China is more than one hundred million tons as the energy consumption of the large country, the yield of the domestic onshore oil and gas field is reluctantly stable, and experts estimate that the large country hardly has major breakthrough in a short term. Natural gas hydrates, which are readily combustible ice, are gaining favor as an alternative energy source in countries throughout the world, particularly in developed countries.
Taking gas hydrates formed at the sea floor as an example: at the ambient temperature of 1-20 ℃, as long as the water depth is 300 meters, namely 30 atmospheric pressures are reached, natural gas hydrate, namely a combustible ice mineral deposit, can be formed; and the environment being above the temperature or/and the environment being below the pressure, the natural gas hydrate is encouraged to decompose into methane and water.
The storage amount of combustible ice minerals in the world is 2 times of the storage amount of combustible minerals such as petroleum, and the combustible ice minerals can be used by the global population for 1000 years; theoretical calculation, 1m 3 Can release 164m under standard conditions 3 Methane gas, while natural gas hydrate combustion produces only CO 2 And H 2 O, which is an inexhaustible green clean energy.
The south China sea contains abundant combustible ice deposits on the sea bottom, however, the combustible ice deposits are not mined out like other sea areas in the world, and the main reason is that the mining cost of the combustible ice is high, about $ 200/m 3 。
Many "laboratory" methods have been developed, but these methods are in the exploration phase and are difficult to enter into practical, scalable commercial exploitation phases.
Disclosure of Invention
The purpose of the invention is: the power generation method solves the problem that when a methane generation generating device of the exposed combustible ice mineral deposit on the surface of the seabed is exploited, wind power can be directly applied to needed power equipment nearby.
The key point of the invention is that:
mainly provides a method for getting enough electricity from wind power resources which never stop within a certain height range above the water surface nearby when the underwater equipment needs the electricity,
the invention has the characteristics that:
the problem of insufficient power supply in an area far from the continents is not worried about.
