Description
Technical field
The present invention relates to a kind of extensive energy storage method based on electricity-aluminium-hydrogen circulatory system, described method is that the form that the excrescent electric power with the power station converts to electrolytic aluminium stores, and stable method to mains supply belongs to power station and power transmission and transformation applied technical field.
Background technology
Because the fast development of China's economic construction and the raising of living standards of the people are growing to the demand of electric power,, but still do not satisfy the active demand that electric load increases although country greatly develops distributed energy resource system.
At present, distributed power generation remains at two big technology barriers: the one, and distributed power generation is connected with electrical network; The 2nd, the energy storage problem.Distributed energy, for example there are randomness in solar energy and wind energy, can not need equipment such as supporting batteries, inverter to electrical network and regional user's stable power-supplying, thereby increase the system cost of distributed power generation.In addition, in the low power consumption period at night, most of electric power of wind power generation can waste.Therefore, based on the consideration of the stability of a system and economy, it is important that the power station energy storage especially seems.
But existing energy storage technology all has corresponding shortcoming: the storage battery charge storage ability is little, and traditional batteries to store energy life-span is short, and energy density is low, causes it to realize that the large-scale power station energy storage is limited to; The energy storage shortcoming of drawing water is that transformation efficiency is not high, and is subjected to the restriction of region, landform; Electrolytic seawater comes the mode of storage of electrical energy to be subjected to hydrogen storage, limitation that transport difficulty is big again with hydrogen.Therefore, press for a kind of novel energy-storing method that can alleviate power shortage at present.
Metallic aluminium has characteristics such as aboundresources, energy density are big, cheap, easy preservation, is a kind of very promising energy carrier.The reaction of aluminium water discharges a large amount of heats and hydrogen.But common metal aluminium is difficult to realize above-mentioned application, and reason is the active medium of metallic aluminium, and the surface easily generates fine and close oxide-film Al
2O
3,, cause the reaction of aluminium water to be difficult to continue securely attached on the aluminium surface.In engineering practice, confirm, high-calcium fly ass provides alkaline environment, active principle in the pulverized coal ash has also played the effect of catalysis to course of reaction on the other hand, the dense oxidation film that aluminium forms in empty G﹠W is dissolved destruction under the synergy of fly ash grain, and with directly reaction and produce a large amount of hydrogen of water, can realize on-the-spot hydrogen manufacturing and instant hydrogen supply fully, the high-purity hydrogen of generation can be by hydrogen fuel cell to mains supply, aluminium water product Al
2O
3Can under the heavy current effect, produce metallic aluminium by the electrolytic aluminium device, thereby reach the purpose of power station energy storage.
Summary of the invention
The objective of the invention is at above-mentioned the deficiencies in the prior art, and provide a kind of indirect energy storage method of large-scale power station, use this method the excrescent electric power at low power consumption and the night form with electrolytic aluminium can be stored, when regional peak of power consumption, can be with aluminium powder and water reaction, at once produce a large amount of, high-purity hydrogen, stable by hydrogen fuel cell to mains supply, to reach the purpose of peak regulation and raising power consumption efficiency.
The object of the present invention is achieved like this: a kind of extensive energy storage method based on electricity-aluminium-hydrogen circulatory system, this method is that the electrolytic aluminium device is inserted outlet line in the power station, convert unnecessary electric energy to aluminium powder by described electrolytic aluminium device, utilize the pulverized coal ash of described aluminium powder and proportioning mass ratio 70% to make raw mineral materials and the water reaction makes hydrogen, the alkaline environment of pulverized coal ash in the raw material in order to provide aluminium water to react, and play the catalytic reaction effect.Convert described hydrogen to electric energy by hydrogen fuel cell, the aluminium oxide that aluminium powder and water reaction obtain is as the raw material of described electrolytic aluminium device.
The present invention compares with existing energy storage technology has following beneficial effect: 1. energy storage method of the present invention can make full use of low power consumption, and such as the excrescent electric power resource at night, electric energy stores with the form of electrolytic aluminium the most at last, and charge storage ability is big; 2. utilize electrolytic aluminium energy storage mode flexible, water consumption seldom is not subjected to the restriction of region; 3. the aluminium oxide that obtains of aluminium water reaction can be as the raw material of aluminum electrolysis technology, thereby recycling, is not subjected to the limitation of resource; 4. discharge type is convenient flexibly, avoids the difficult problem of hydrogen storage, transportation; 5. utilize power plant's waste material-pulverized coal ash, realize changing waste into resources.
