目前也正在生产使用可再生能源生产的绿色氢，但与灰色氢相比，其成本仍然极高。但许多可再生能源项目多年来一直在努力使绿色氢具有竞争力，今年早些时候，由于石油巨头荷兰皇家壳牌(Royal Dutch Shell)参与了这一倡议，建立了一个海上风力发电场，这一领域获得了重大提升。绿色氢革命即将来临。 现在，它已成为关于能源未来的激烈辩论的中心。

Energy Giants Race For 'Green Hydrogen' Market Share
Green hydrogen is red hot. While hydrogen has long been touted as a virtually inexhaustible source of clean energy, with zero carbon emissions since this first element on the periodic table burns clean, leaving behind only water vapor. This makes hydrogen highly marketable as a promising fuel source option for a decarbonized economy of the future. The idea of a new energy order has gained a ton of attention in the wake of the novel coronavirus’ unprecedented interruption to the energy sector status quo, with such influential organizations as the World Economic Forum calling for a “great reset”. Not all hydrogen is created equal, however. Hydrogen power is not a novelty; it is already widely used in commonplace industrial processes such as ammonia production, in refineries and as a feedstock for chemicals. The standard hydrogen used in these production processes, however, is not as “green” as you may think. It’s created through the use of fossil fuels, primarily coal and natural gas. This form of hydrogen is known as “grey hydrogen,” and is essentially useless in terms of reducing greenhouse gas emissions.
Green hydrogen, which is produced using renewable energy, is also currently in production, but it is still extremely cost prohibitive compared to gray hydrogen. But plenty of renewable energy projects have been trying to make green hydrogen competitive for years, and the sector got a major bump earlier this year as oil supermajor Royal Dutch Shell got involved in the initiative with an offshore wind farm. The green hydrogen revolution is upon us. And now it's found itself at the center of the raging debate about the future of energy.
“Within the span of a week, major utilities Iberdrola, Uniper and NextEra all made moves into the hydrogen market, in a reminder that the miracle molecule is not the sole domain of the oil and gas sector,” Greentech Media reported just this week. “But whether utilities will have the ability — or need — to compete with oil companies in the emerging hydrogen market remains an open question.”
While supermajor oil companies like Shell, BP and Equinor have dominated the hydrogen sector in terms of gigawatt scale, utilities are giving them a run for their money, particularly in Europe, the U.S., and Canada.
