據(jù)能源世界網(wǎng)7月15日倫敦報(bào)道，英國公用事業(yè)公司(SSE)子公司英國SSE熱力公司和挪威油氣巨頭Equinor表示，他們正在制定計(jì)劃，在東約克郡海岸現(xiàn)有的天然氣存儲站點(diǎn)存儲氫氣。
這個被稱為阿爾德伯勒(Aldbrough)的地方，由9個地下鹽穴組成，這些鹽穴將被轉(zhuǎn)換成儲存氫。
兩家公司稱，該項(xiàng)目將于2028年完成，預(yù)計(jì)產(chǎn)能至少為320吉瓦時，可能需要建造更多的洞穴。
從化石燃料中產(chǎn)生的氣態(tài)氫已在地下洞穴中儲存多年。
該站點(diǎn)將用于存儲來自亨伯地區(qū)的氫氣，該地區(qū)正在開發(fā)低碳?xì)錁屑~中心。從本世紀(jì) 20年代末起，氫氣將用于供熱、工業(yè)和運(yùn)輸市場。
使用可再生能源生產(chǎn)的氫，是一種低碳燃料，并被一些國家吹捧為大幅減少溫室氣體排放的一種方式。
但成本仍然很高，基礎(chǔ)設(shè)施匱乏，而且由于氫氣的密度低于天然氣，必須在工業(yè)場所或汽車燃料補(bǔ)給站安全壓縮、儲存和分配。
兩家公司表示，雖然阿爾德伯勒(Aldbrough )工廠最初將儲存為Keadby氫電站提供燃料而生產(chǎn)的氫，但其將使越來越大的氫野心成為可能，包括從本世紀(jì)20年代末開始，供應(yīng)包括供熱、工業(yè)和運(yùn)輸在內(nèi)的不斷擴(kuò)大的承購市場。
儲氫將對在英國建立一個大規(guī)模的氫經(jīng)濟(jì)，并通過為大部分能源來自可再生能源的地區(qū)提供備用能源提供后備能源來平衡整個能源系統(tǒng)至關(guān)重要。
使用可再生能源生產(chǎn)的氫氣是通過電解實(shí)現(xiàn)的，電解將水分解成氫氣和氧氣。
SSE Thermal董事總經(jīng)理斯蒂芬·惠勒(Stephen Wheeler)表示，通過提供大規(guī)模的氫儲存能力，我們可以利用氫來實(shí)現(xiàn)重要發(fā)電、重工業(yè)、熱能、運(yùn)輸和其他難以實(shí)現(xiàn)的行業(yè)的脫碳，保護(hù)和創(chuàng)造該地區(qū)關(guān)鍵的就業(yè)和投資。

SSE, Equinor plan to store hydrogen at UK gas storage site
Britain's SSE Thermal, part of SSE and Norwegian oil and gas company Equinor said they are developing plans to store hydrogen at their existing gas storage site on the East Yorkshire coast.
The site, called Aldbrough, consists of nine underground salt caverns which would be converted to store hydrogen.
The project, due to be completed by 2028 with an expected capacity of at least 320 gigawatt hours, might require additional caverns to be built, the firms said.
Gaseous hydrogen produced from fossil fuels has been stored underground in caverns for many years.
The site would be used to store hydrogen from the Humber region, where a low-carbon, hydrogen hub is being developed. The hydrogen would be used for the heat, industry and transport markets from the late 2020s onwards.
Hydrogen, if produced using renewable energy, is a low-carbon fuel and is being touted by several countries as a way to dramatically cut greenhouse gas emissions.
But costs are still high, infrastructure is lacking and as hydrogen is less dense than natural gas and must be safely compressed, stored and dispensed at industrial sites or refuelling stations for vehicles.
The companies said that while the Aldbrough facility would initially store hydrogen produced to fuel the Keadby Hydrogen Power Station, it would enable growing hydrogen ambitions, including supplying an expanding offtaker market including heat, industry and transport from the late 2020s.
Hydrogen storage will be vital in creating a large-scale hydrogen economy in Britain and balancing the overall energy system by providing backup where large proportions of energy are produced from renewable power.
Hydrogen produced using renewable power is done by electrolysis, which splits water into hydrogen and oxygen.
"By delivering large-scale hydrogen storage capacity, we can utilise hydrogen to decarbonise vital power generation, as well as heavy industry, heat, transport, and other hard-to-reach sectors, safeguarding and creating crucial jobs and investment across the region," said Stephen Wheeler, managing director of SSE Thermal.
