In Feicheng in spring, the salt cavern in the depth of 1,000 meters underground is experiencing a profound “value rebirth”. Recently, at the site of the 350MW salt cavern compressed air energy storage project built in China, giant spherical tanks and crisscross pipe networks form a picture of modern energy industry. As the energy storage project with the largest power of grid-connected power generation units in the world, it will inject strong power into regional energy supply.
At the same time, the construction of the 2 × 300MW salt cavern energy storage project of CLP is accelerating simultaneously, and it is planned to realize full-capacity grid-connected power generation this year. From the abandoned salt cave in the past to today’s “power bank”, Feicheng is writing a legend of the transformation of a resource-based city on its unique resource endowment and hard-core technological innovation as its wings on the future industrial track.
The sustainable development of resource-based cities has always been faced with the strategic choice of “eating the old capital” and “opening a new bureau. As one of the largest well and mineral salt production bases in Shandong, Feicheng has a proven rock salt reserve of 5.02 billion tons, which was once a “solid foundation” for the city’s survival “. However, Feicheng did not indulge in short-term resource dividends, but had a keen insight into the urgency and inevitability of the transformation of the traditional resource mining industry, and laid out the road of industrial upgrading early.
When many areas are still wandering in the contradiction between resource consumption and ecological protection, Feicheng has taken the lead in breaking the situation and embarked on a unique road of green transformation. This transformation is by no means a simple reuse of resources, but a leap in industrial upgrading through technological empowerment, successfully opening up a new type of energy storage, a high value-added industrial track, and achieving a win-win situation of ecological and economic benefits.
Technological innovation is the core competitiveness of the future industry, and it is also the key password for the breakthrough of the energy storage industry in Feicheng. The 350MW project of China Energy Construction adopts non-supplementary combustion technology to realize zero fossil energy consumption and zero carbon emission in the whole process. The 2 × 300MW project of China Power Construction takes the high-quality salt cave with a depth of 1300 meters as the energy storage carrier, and has been awarded the national green and low-carbon advanced technology demonstration project with its strong adjustment ability of “cutting peaks and filling valleys. Up to now, eight national firsts have been created here, such as “completed power station capacity” and “single unit capacity under construction”. The core technology is constantly upgraded in practice.
the development of the energy storage industry in Feicheng is not an isolated pile of projects, but a complete industrial chain ecology of “front-end salt production and expansion, middle-end salt cave energy storage, and back-end network extension. At present, 22 new energy storage projects have taken root in Feicheng, and a number of key enterprises such as China Power Construction and PetroChina have rushed to settle in, forming a significant industrial cluster effect and scale advantage. Taian new energy storage industry demonstration base with a total installed capacity of 3480MW has accelerated its formation, laying a solid foundation for Taian to build a “energy storage capital” of 10 million kilowatts.
Resource-based cities are not destined to fall into the fate of “mine exhaustion and city decline”. As long as they find the right transformation track and uphold the tenacity of long-term success, they can transform resource advantages into industrial advantages and upgrade traditional industries into future industries. From a single resource exploitation to the coordinated development of the entire industry chain, from relying on traditional resources to embracing green energy, Feicheng’s transformation road provides a vivid model for the future industrial development of resource-based cities.
now, the underground salt cave extends in depth, green power sources converge, Feicheng is based on unique resource endowments, takes scientific and technological innovation as the engine, actively explores new energy utilization modes such as salt cave energy storage, boldly breaks the problem and makes accurate efforts on the road of energy transformation, builds a solid foundation for development with solid work, activates transformation momentum with innovative practices, and strives to write a new chapter of high-quality development.
