氢的创新

西班牙&E is exploring how clean hydrogen can support energy reliability, 可负担性和公平性 as we help California reach Net Zero by 2045.

氢——实现我们的低碳未来

Clean hydrogen is poised to become an integral component of the global low carbon economy of the future through the reduction of greenhouse gas (GHG) emissions on both the electric and gas grids. Our region and state are well-suited to pioneer clean hydrogen due to the abundance of solar energy that can be leveraged to produce this carbon-free, 气体能量载体.

特别是在可持续发展目标方面&E, we are exploring the potential of clean hydrogen to help California achieve net zero GHG emissions by 2045. 作为我们可持续发展战略, we are developing pilot projects that will test hydrogen for long-duration energy storage, 发电, 车辆加油, and blending into an existing natural gas system.

可持续发展目标下的氢&E

在西班牙&E, we are committed to studying how clean hydrogen can help us meet California's climate action goals while addressing energy reliability, 可负担性和公平性. 通过多个项目, we will develop and implement real-world demonstrations that expand industry knowledge and advance hydrogen innovation.

加州大学圣地亚哥分校-氢混合

2022年9月，可持续发展目标&E submitted a proposal to the California Public Utilities Commission (CPUC) to demonstrate hydrogen blending on the UC San Diego campus. 如果CPUC批准, the project will study the impact of hydrogen blended natural gas (up to 20%) in infrastructure materials common to the natural gas distribution system — addressing the need to fill knowledge gaps to inform a hydrogen blending injection standard.

Palomar Energy Center — 电 Generation and Fleet Fueling

在埃斯孔迪多的帕洛玛能源中心, an onsite electrolyzer and solar panels will be installed to produce hydrogen that will be blended with natural gas for 发电. This hydrogen will also be used to fuel the first hydrogen vehicles in our fleet, and as a cooling gas in the combined cycle process.

氢101

氢 is the simplest and most abundant element in the universe. Many stars, including the sun, are primarily hydrogen combined with other gases like helium. 究竟, hydrogen is rarely found in its pure form; instead, it’s typically found in compounds such as water (H或化石燃料，如甲烷(CH4).

几十年来,, hydrogen has been used as a feedstock in industrial, 制造业, 以及技术运营, including the production of ammonia for agriculture, 炼油, 电子制造业. But hydrogen is also a carbon-free energy carrier, 这意味着它可以用来存储, move and deliver energy produced from other sources, 当被用作燃料时, it produces water vapor instead of GHG emissions.

由于其独特的特点, experts and policymakers across the globe acknowledge that clean hydrogen will play a major role in achieving carbon neutrality goals.

氢是如何产生的?

Currently, most of the hydrogen produced in the U.S. is made from natural gas, through a chemical process called Steam Methane Reforming (SMR). 这个过程释放二氧化碳作为副产品.

But hydrogen can also be produced through other “clean” pathways. One of those pathways is called electrolysis, the process of using electricity to separate oxygen and hydrogen atoms in water. If renewable (such as solar or wind) electricity is used, the process is completely carbon free.

氢是如何储存的?

因为氢是气体, it is typically stored in pressurized containers, 比如小圆柱体, 大型储罐或地下储罐. It can also be stored as a liquid at very cold temperatures. 比如天然气, hydrogen can be stored for long periods of time and transported to different locations. Large-scale hydrogen storage can be especially useful because it provides a steady energy source even if production is irregular.

如何使用氢?

氢 is described by some as the “building block of the clean energy economy” in that it has many uses to help build a more sustainable future. Because it can be efficiently stored and transported in different forms, hydrogen can be produced where and when clean energy is abundant and help decarbonize hard-to-electrify sectors such as steel or aluminum production or long-haul transportation.

Some of the many uses currently being explored include longer-duration storage that could be used to power regions or buildings, 零排放燃料电池汽车, and blending with natural gas to help decarbonize our existing energy system.
