據油價網2021年7月14日報道，美國能源部7月14日宣布了一個新的目標，在未來10年內通過將電網規模的長期能源儲存成本降低90%，以支持更多的風能和太陽能在電網中的推廣。

　　美國能源部的計劃有非常雄心勃勃的目標，要加速技術上的突破，使清潔電力的儲存能夠隨時隨地使用。 分析人士表示，2030年將鋰離子電池的成本比現在低90%的目標并不容易實現。

　　政府的目標是不遲于2035年建立無碳污染的電力行業。 這本身就是一個巨大的挑戰，因為在2020年，天然氣占美國公用事業規模發電量的40.3%，化石燃料占60.3%，而煤炭占電力結構的19.3%。

　　美國能源部長詹妮弗·格蘭霍姆7月14日宣布了這個到2030前將長期能源儲存成本降低90%的目標：

　　“在未來幾年內，我們將把數百吉瓦的清潔能源引入電網，我們需要能夠隨時隨地使用這些能源?！?/p>

　　格蘭霍姆補充說：“這就是為什么美國能源部正在積極致力于更廉價、更持久的能源儲存，以實現目標，即到2035年前實現100%的清潔電力?！?/p>

　　內斯特·塞普爾韋達日前在接受《紐約時報》采訪時表示：“這些成本目標并不容易實現，盡管它們與許多開發者的目標一致?！?塞普爾韋達是麻省理工學院的研究員，最近他領導了一項關于能源儲存成本的研究。

　　塞普爾韋達補充說：“目前的一個大障礙是，沒有政策要求公用事業公司建立長期能源儲存。 簡單地燃燒天然氣更容易、更便宜?！?/p>

　　與此同時，美國儲能市場正在蓬勃發展，據伍德麥肯茲和美國儲能協會的最新估計，今年第一季度，新儲能系統上線910兆瓦時(MWh)。 這一數字比去年第一季度增長了252%，成為美國儲能市場迄今為止最大的第一季度。

　　U.S. Looks To Slash Long-Duration Energy Storage Costs By 90% By 2030

　　The U.S. Department of Energy announced on Wednesday a new goal to support the increased rollout of more wind and solar power in the grid by reducing the cost of grid-scale, long-duration energy storage by 90 percent within the decade.

　　The DOE initiative has very ambitious goals to accelerate breakthroughs in technology that could enable the storage of clean electricity to make it available anytime, anywhere. Analysts say that the target to slash costs 90 percent below today’s lithium-ion batteries within 2030 would not be easy to achieve.

　　The Administration targets a carbon pollution-free electricity sector no later than 2035. This in itself is a huge challenge considering that natural gas accounted for the largest share of U.S. utility-scale electricity generation in 2020, at 40.3 percent, with fossil fuels at 60.3 percent share, also due to coal’s 19.3-percent share of the power mix.

　　Announcing the goal of reducing the cost of long-duration energy storage by 90 percent by 2030, U.S. Secretary of Energy Jennifer Granholm said today:

　　“We’re going to bring hundreds of gigawatts of clean energy onto the grid over the next few years, and we need to be able to use that energy wherever and whenever it’s needed.”

　　“That’s why DOE is working aggressively toward cheaper, longer duration energy storage to reach? goal of 100% clean electricity by 2035,” Secretary Granholm added.

　　“Those cost targets won’t be easy to hit, although they’re in line with what many developers are aiming for,” Nestor Sepulveda, who led a recent study about storage costs as a researcher at the Massachusetts Institute of Technology, told The New York Times.

　　“One big obstacle right now is that there’s no policy requirement for utilities to build long-duration storage. It’s easier and cheaper to simply burn natural gas,” Sepulveda added.

　　Meanwhile, the U.S. energy storage market is booming, with 910 megawatt-hours (MWh) of new energy storage systems brought online in the first quarter of 2021, according to the latest estimates from Wood Mackenzie and the U.S. Energy Storage Association. The figure was a 252-percent jump over Q1 of last year, making it the biggest Q1 so far for the U.S. storage market.
