據(jù)世界天然氣4月19日消息：美國公用事業(yè)公司Dominion Energy表示，它將通過開發(fā)將氫氣混入其氣體分配系統(tǒng)的試點(diǎn)項(xiàng)目，邁向能源轉(zhuǎn)型的下一步。
該公司在猶他州的一家工廠開始了一個(gè)試點(diǎn)項(xiàng)目，該項(xiàng)目設(shè)想將少量氫氣混入其天然氣管線中，以了解其性能，然后為其超過100萬猶他州的天然氣公用事業(yè)客戶引入燃料選項(xiàng)。北卡羅來納州也設(shè)想了類似的項(xiàng)目。
“我們現(xiàn)在正在投資氫氣，希望它能在五到十年內(nèi)改變清潔能源的格局。” Dominion首席創(chuàng)新官M(fèi)ark Webb說。
Dominion稱之為“清潔能源的瑞士軍刀”，該公司認(rèn)為，氫氣可以在能源領(lǐng)域扮演與天然氣相同的角色，但總體排放量更少。
此外，這家總部位于弗吉尼亞州的公用事業(yè)公司表示，它正在研究將氫氣用于電力、運(yùn)輸和制造等領(lǐng)域的方法。
Dominion為700多萬家庭提供天然氣，它承諾到2050年，其發(fā)電和天然氣基礎(chǔ)設(shè)施運(yùn)營將實(shí)現(xiàn)二氧化碳和甲烷的凈零排放。
去年11月，該公司停止向伯克希爾哈撒韋的子公司伯克希爾哈撒韋能源公司出售其大部分天然氣輸送和儲存資產(chǎn)。涉及的資產(chǎn)包括5500多英里的州際輸氣管道、約7750億英尺的天然氣存儲以及Cove Point液化天然氣終端25%的股份。

US UTILITY DOMINION TRIES HYDROGEN ON FOR SIZE
US utility Dominion Energy said April 19 it was taking its next steps in the energy transition by developing pilot projects to blend hydrogen into its gas distribution systems.
At a facility in Utah, the company said it started a pilot project that envisions blending small amounts of hydrogen into its gas lines to see how it behaves before introducing the fuel option for its more than 1mn Utah gas utility customers. A similar project is envisioned for North Carolina.
“We're investing in hydrogen today so it can hopefully transform the clean energy landscape in five or 10 years,” Mark Webb, the chief innovation officer at Dominion, said.
Calling it the “Swiss Army knife of clean energy,” Dominion said hydrogen can fill the same role as natural gas in the energy sector, but with fewer overall emissions. Dominion did not reveal the origin of the hydrogen for its pilot projects.
Elsewhere, the Virginia-based utility said it was looking at ways to utilise hydrogen for electricity, transportation and manufacturing, among other things.
Dominion, which supplies gas to over 7mn households, is committed to net zero CO2 and methane emissions from its power generation and gas infrastructure operations by 2050.
In November, it closed on the sale of the majority of its gas transmission and storage assets to Berkshire Hathaway Energy, an affiliate of Berkshire Hathaway. The assets involved included more than 5,500 miles of interstate gas transmission pipelines, about 775bn ft3 of operated gas storage and an operating 25% stake in the Cove Point LNG terminal.
