Solar power in Scotland start-ups will use the new type of gravity system to store wind energy and solar energy

Scottish start-ups gravity ricity developed a gravitational energy storage system, it claims the system is very suitable for storage of solar energy and wind power.

16 meters high rig using clean energy - in 150 Improve quality, in the 1500 - meter shaft and rotate through the release of quality generators, thus & other Storage & throughout; Electric power.

gravity ricity company said that the matter can be used from 500 tons to 5000 tons, the release of power can provide near 30000 households with two hours of electricity.

the start-up that advanced winch and the control system can reduce the quality very quickly, to make it flexible enough, solar panels, can be stable in 50 hz power network, and ensure that can set up in less than a second time response all electricity demand. The company said: & other; Our technology has fast response time of lithium ion batteries. ”

the company is headquartered in Edinburgh, said the system provides 25 years of service, there will be no performance loss or cyclic degradation, can be installed in any place, including the town center. However, solar energy, developers said abandoned mine is the ideal place.

in October this year, the company will close in Scotland's largest deep water port, port ( 港利思) An industrial base to start building a cost 1 million pounds ( 1. 14 million euros) The pilot projects.

as the plan completed in December, China solar energy network, 250 kw prototype will be connected to the ports of the power grid, and to evaluate the response speed of the power grid stability. The company said: & other; Port, the demo will allow the test technology on a smaller scale, using a ground structure. ”

pilot system will use two 25 tons of wire suspension. “ This two-month test project will confirm our model, and we will start in 2021 the first full size 4 mw project provides valuable data, & throughout; The company's chief engineer & myers middot; Franklin ( 迈尔斯•富兰克林) Said.

, port facilities, lattice tower will be provided by the British engineer kelvin electric power company, winch and the control system will be provided by the Dutch huisman wyman company, the company production of heavy lifting, drilling, pipelines and mooring system.

a year ago, the U. S. Energy company Vault introduced based on the gravity of the Energy storage technology, the technology relies on a crane and 35 tons of concrete block. According to the developers of the system, the system is said to be considering the energy supply and demand fluctuations and inertia factors such as, weather conditions, and gets the Japanese lenders softbank in August ( SoftBank) 1. 100 million dollars ( 1. 0. 2 billion euros) Support the investment. The Japanese enterprise group announced at that time, & other; Energy Vault will be shown in northern Italy in 2019, the first 35 mw Energy storage tower. ”

the Austrian research institute, the international institute for applied systems analysis ( IIASA) Last year suggested that attractive energy storage in low energy demand area. In this case, the gateway to solar power, solar power network, put forward the technology including the double crane on the edge of a cliff, energy storage point of connection to the bottom of the drop, plus on top of energy-storage motor, used to transport a large number of solid sand or gravel. IIASA scientists say that such a system can be combined with other forms of energy storage and renewable energy, 50 - per mw The stored energy and 1-100 dollars $2 million per megawatt of installed capacity development.
