Outdoor Energy Storage (Portable Power) Recently, outdoor energy storage, a branch of new energy storage, has suddenly exploded in the global market. According to public information, in the past 4 years, the size of the portable energy storage market has increased by 23 times. From the perspective of sales distribution, the US and Japanese markets account for more than 75%. Chinese companies have become the biggest beneficiaries of this wave of market boom. According to data, China's output of portable energy storage products accounted for 91.9% of the world's total in 2020. The portable energy storage market is growing rapidly. In addition to the increase in demand for outdoor products brought about by the unblocking of overseas markets, technological changes on the supply side are also factors that cannot be ignored. The development of the new energy automobile industry has greatly improved the energy storage efficiency of lithium batteries, but the cost has been rapidly reduced. The data shows that the average unit cost of lithium battery packs has fallen by nearly 80% over the past decade. Research institutions predict that the energy storage market will grow at a compound annual growth rate of 48% in the next five years and reach 80 billion yuan in 2026. Unicorns with annual sales of tens of billions will be born in China in the not-too-distant future.   Introduction: In recent years, the demand for portable power supply solutions has increased significantly due to the growing popularity of outdoor activities and the need for reliable energy sources in remote locations. As a result, outdoor energy storage, also known as portable power, has emerged as a convenient and efficient solution for powering devices on the go. This article explores the concept of outdoor energy storage and its applications in various outdoor settings.   1. Definition and Components of Outdoor Energy Storage: Outdoor energy storage refers to the use of portable power systems to store and supply electricity for outdoor activities. These systems typically consist of a rechargeable battery, an inverter, and various input/output ports for connecting different devices. The battery stores the energy, while the inverter converts it into usable AC or DC power. The input/output ports allow for the connection of devices such as smartphones, cameras, camping lights, and even small appliances.   2. Advantages of Outdoor Energy Storage: a. Portability: The main advantage of outdoor energy storage is its portability. These systems are designed to be lightweight and compact, allowing users to easily carry them in backpacks or travel bags. b. Versatility: Portable power supplies can be used in a wide range of outdoor activities, including camping, hiking, fishing, and boating. They provide a reliable source of power for charging devices or running small appliances, ensuring convenience and comfort in outdoor settings. c. Renewable Energy Integration: Many portable power systems can be charged using renewable energy sources such as solar panels or wind turbines. This enables users to harness clean and sustainable energy while enjoying the outdoors.   3. Applications of Outdoor Energy Storage: a. Camping: Portable power supplies are essential for camping trips, providing electricity for lighting, charging phones, powering portable refrigerators, and running small cooking appliances. b. Hiking and Backpacking: Outdoor enthusiasts can rely on portable power supplies to charge their GPS devices, smartphones, and other electronic gadgets during long hikes or backpacking trips. c. Emergency Preparedness: During emergencies or power outages, portable power supplies can be used to power essential devices like radios, medical equipment, and emergency lights. d. Outdoor Events: Portable power supplies are commonly used in outdoor events such as festivals, concerts, and sports competitions. They provide a convenient and reliable power source for lighting, sound systems, and other equipment.   Conclusion: Outdoor energy storage, or portable power, has revolutionized the way we access electricity in outdoor settings. Its portability, versatility, and ability to integrate with renewable energy sources make it an ideal solution for powering devices on the go. Whether for camping, hiking, emergencies, or outdoor events, portable power supplies offer convenience, reliability, and peace of mind.  

China's first 10,000-ton-level photovoltaic hydrogen production project was put into operation, with a hydrogen production capacity of 20,000 tons/year by electrolysis of water, and zero carbon emissions in the whole process. On June 30, my country's first 10,000-ton photovoltaic green hydrogen demonstration project - Sinopec Xinjiang Kuqa Green Demonstration Project will be put into operation to produce hydrogen. This marks the first time that my country has realized the industrial application of large-scale photovoltaic power generation direct hydrogen production process and engineering complete set of technology, providing a replicable and scalable demonstration case for the development of domestic photovoltaic power generation hydrogen production industry. Green hydrogen is directly produced by renewable energy such as solar energy and wind energy, and basically does not produce greenhouse gases during the production process. The project utilizes abundant solar energy resources in Xinjiang to directly produce green hydrogen. The hydrogen production capacity of electrolyzed water is 20,000 tons/year, the hydrogen storage capacity is 210,000 standard cubic meters, and the hydrogen transmission capacity is 28,000 standard cubic meters per hour. The green hydrogen produced will be supplied to the nearby Sinopec Tahe River Industry to completely replace the existing natural gas fossil energy hydrogen production, which can reduce carbon dioxide emissions by 485,000 tons per year.

Photovoltaic industry, referred to as PV, is a power generation system that uses solar energy to generate electricity, and is characterized by the application and development of silicon materials to form a photoelectric conversion into an industrial chain. Photovoltaic industry is increasingly becoming a fast-growing industry after T and microelectronics industry in the world. The development of the photovoltaic industry is of great significance to China's adjustment of energy structure, promotion of changes in energy production and consumption patterns, and promotion of ecological civilization.
