Hydrogen Powertrain Key Concepts
On Hydrogen Power
Hydrogen power is a new power technology today. It uses hydrogen as the source, energy transformation as the action, and travels in water, land and air vehicles, which is completely different from the usual fuel power. When covering hydrogen combustion, only raw water and no filth are used, which is great for environmental protection, so it is of great importance to the world today.
Key Concepts of Hydrogen Power
Hydrogen Source Acquisition
Although hydrogen exists widely in the world, it is mostly combined with other substances and rarely exists as a single substance. Therefore, if you want to obtain usable hydrogen, you must apply the method of separation. The first is electrolysis of water, which is converted into hydrogen and oxygen by electrosplitting water. If the electricity is taken from clean energy such as wind and light, the hydrogen production in this way is pure and pure; the second is the reforming of fossil fuels, such as natural gas reforming. Although hydrogen is produced a lot, there is a worry about carbon emissions. It must be supplemented by the technique of carbon capture to meet the purpose of clean energy.
Storage and transportation
Hydrogen is light and scattered, and storage and transportation are not easy. The way to store hydrogen is to have high-pressure gaseous hydrogen storage, which uses strong pressure to concentrate hydrogen in the tank, but requires thick-walled devices, which are heavy and wide; there is low-temperature liquid hydrogen storage, which forms a liquid from cold hydrogen to below the boiling point, and the storage density is greatly increased, but the cooling energy consumption is huge; there is also solid hydrogen storage, which absorbs hydrogen through special materials, which is safe and has a considerable storage density. However, the research and development of materials still needs to be refined. Transportation, pipeline transportation, or vehicle transportation, each has its own advantages and disadvantages, and must be selected according to the situation.
Power conversion
Hydrogen conversion power depends on fuel cells and hydrogen internal combustion engines. For fuel cells, hydrogen and oxygen are passed through the electrodes, and electricity is generated by electrochemical reaction to drive the device, which is highly efficient and quiet; for hydrogen internal combustion engines, it is similar to traditional internal combustion engines. It uses hydrogen instead of oil to burn in the cylinder, which has strong power, but the efficiency is slightly inferior, and the engine needs to be modified. The two have their own strengths and are suitable for different domains.
The rise of hydrogen power is the key to the future power revolution. Although the way forward, the technology needs to be advanced, the cost needs to be reduced, and the supporting equipment needs to be completed, its prospects are broad, and it must be the mainstream of clean energy power and lead the new chapter of power in the world.
