中国石化新闻网讯 据世界天然气4月19日消息：美国公用事业公司Dominion Energy表示，它将通过开发将氢气混入其气体分配系统的试点项目，迈向能源转型的下一步。 该公司在犹他州的一家工厂开始了一个试点项目，该项目设想将少量氢气混入其天然气管线中，以了解其性能，然后为其超过100万犹他州的天然气公用事业客户引入燃料选项。北卡罗来纳州也设想了类似的项目。 “我们现在正在投资氢气，希望它能在五到十年内改变清洁能源的格局。” Dominion首席创新官Mark Webb说。 Dominion称之为“清洁能源的瑞士军刀”，该公司认为，氢气可以在能源领域扮演与天然气相同的角色，但总体排放量更少。 此外，这家总部位于弗吉尼亚州的公用事业公司表示，它正在研究将氢气用于电力、运输和制造等领域的方法。 Dominion为700多万家庭提供天然气，它承诺到2050年，其发电和天然气基础设施运营将实现二氧化碳和甲烷的净零排放。 去年11月，该公司停止向伯克希尔哈撒韦的子公司伯克希尔哈撒韦能源公司出售其大部分天然气输送和储存资产。涉及的资产包括5500多英里的州际输气管道、约7750亿英尺的天然气存储以及Cove Point液化天然气终端25%的股份。 冯娟 摘译自 世界天然气 原文如下： 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. |
