Unknown! Chinese scientists reveal the "magic magic" of solar photocatalytic hydrogen production Solar photocatalytic reactions can split water to produce hydrogen and reduce carbon dioxide to produce "solar fuel". How the magical "magic" of sunlight is realized has always been a difficult problem in the field of science. Recently, good news came from the Chinese Academy of Sciences: the research ...
What does "green hydrogen" energy mean and what can we use it for? Generally speaking, hydrogen often appears in those topics about clean energy. It is habitually described as a completely colorless chemical that burns cleanly and can be used as a substitute for coal, oil or natural gas. But for the use of hydrogen to have environmental benefits, it must be produced in a clean way, not from fossil...
Overview of Hydrogen Fuel Cell Growth During the reaction process of the fuel cell stack, the proton exchange membrane needs to maintain a certain humidity to ensure a high reaction efficiency. Therefore, the reaction medium is required to carry a certain amount of water vapor into the stack. This step is usually realized by a humidifier. . This article analyzes the fuel cell humidifier from six a...
One article to know in detail: knowledge popularization of photovoltaic industry 1. The principle of photovoltaic power generation When a photon irradiates a metal photovoltaic module, its energy can be completely absorbed by an electron in the metal module. The energy absorbed by the electron is large enough to overcome the internal gravitational force of the metal and escape from the metal surfa...
Lay out a new track for the energy storage industry and accelerate the demonstration and application of energy storage technology in power systems (1) Energy storage is an important technology and basic equipment to support the new power system. It is of great significance to promote the green transformation of energy, respond to extreme events, ensure energy security, promote high-quality energy ...
Questions and Answers on Energy Storage | How does the energy storage system cope with weather challenges when the "quick freezing" mode is activated across the country? The China Meteorological Administration mentioned at a press conference in early November that in the face of extreme weather, it is necessary to prevent the adverse impact of cold air on energy supply. It is recommended to prepar...
Mingming from the automobile culture market has his own small circle in the field of automobile consumption. What they care most about the hydrogen energy industry is whether fuel cell vehicles have any advantages? When will it be as popular as lithium-ion battery cars? This is a consumer facing article. Since I have served the automobile culture industry for many years, after switching to the hyd...
With the substantial increase in the proportion of wind and new energy connected to the grid, energy storage has ushered in rapid development under the joint action of policies and markets. In 2021, the cumulative installed power of China's electrochemical energy storage market will reach 5.1GW. According to the forecast of China Chemical (601117) and the Physical Power Industry Association, the i...
The N-type era has begun, what characteristics should the best N-type photovoltaic modules have? As the main theme of the photovoltaic industry, cost reduction and efficiency increase have long promoted the development and upgrading of battery technology. After long-term iterative development of technology, the mass production efficiency of PERC cells in the industry has generally exceeded 23%, an...
Photovoltaic "islanding effect" can be interpreted as when the inverter is connected to the grid, the mains cannot supply power to the local load due to various reasons. At this time, if there is no islanding judgment technology, the inverter will continue to supply the local load and local Grid load power supply. Generally speaking, the photovoltaic island effect may have adverse effects on the e...
