Batteries are quickly becoming cheap, and may soon provide an inexpensive short-term solution to store energy to meet daily needs. However, the long-term storage capacity of batteries (for example, annual cycles) will not be economically feasible.
Although pumped storage (PHS) technology is an economically viable option for large-capacity long-term energy storage greater than 50 megawatts (MW)-it is too expensive for areas where energy storage needs are typically less than 20MW , They need to meet monthly or seasonal needs, such as small islands and remote areas.
In a study published in the journal Energy, IIASA researcher Julian Hunt and colleagues proposed MGES to bridge the gap between existing short-term and long-term energy storage technologies. MGES envisions a crane that utilizes the edge of a steep mountain with a range sufficient to transfer sand (or gravel) from the storage location at the bottom to the storage location at the top.
The motor / generator moves the storage container filled with sand from the bottom to the top, similar to a ski lift. During this process, potential energy is stored. In turn, electricity is generated by putting sand back from the upper storage location to the bottom.
If there are rivers in the mountains, the MGES system can be used in conjunction with hydroelectric power generation. During high-availability periods of hydropower generation, water will be used to fill storage containers to replace sand or gravel to generate energy. The advantage of the MGES system is that water can be added at any height of the system, thereby increasing the possibility of collecting water from different heights in the mountain area, which is impossible in conventional hydropower generation.
Hunter said: "One of the advantages of this system is that sand is very cheap and unlike water, it does not evaporate-so you never lose potential energy and can reuse it countless times. This is especially useful for dry areas. In addition, due to the high hydraulic pressure, the height difference of the pumped storage (PHS) equipment is limited to 1200 meters. "
" The height difference of the MGES energy storage plant may exceed 5,000 meters. Therefore, high mountain areas such as the Himalayas, the Alps and the Rocky Mountains may become important long-term energy storage centers. Other interesting locations of MGES are islands such as Hawaii and Cape Verde , Madeira and some Pacific islands with steep mountains. "
In the article, the author proposes the future energy matrix of Molokai Island, Hawaii, using only wind energy, solar energy, batteries and MGES to meet the energy needs of the island. Hunter emphasized that MGES technology should not be used for peak power generation or storing energy in daily cycles-on the contrary, it can fill the market gap for long-term energy storage. For example, the MGES system can store energy for several months in a row, and then generate power continuously for several months or when water is available for hydropower generation, and the battery is responsible for the daily energy storage cycle.
Hunter concluded: "The important thing is that MGES technology will not replace any existing energy storage solutions, but will open up new energy storage methods and take advantage of the untapped hydropower potential in high mountains.
