Identifying and building a sustainable energy system are perhaps two of the most critical issues that today's society must address. Replacing our current energy carrier mix with a sustainable fuel is one of the key pieces in that system. Hydrogen as an energy carrier, primarily derived from water, can address issues of sustainability, environmental emissions, and energy security. Issues relating to hydrogen production pathways are addressed here. Future energy systems require money and energy to build. Given that the United States has a finite supply of both, hard decisions must be made about the path forward, and this path must be followed with a sustained and focused effort.
识别并构建一个可持续能源系统或许是当今社会必须面对的两个最为关键的问题。用可持续燃料取代我们当前的能源载体组合是该系统的关键环节之一。氢作为一种主要源自水的能源载体，能够解决可持续性、环境排放以及能源安全等问题。本文将探讨与制氢途径相关的问题。未来的能源系统建设需要资金和能源。鉴于美国在这两方面的供应都有限，必须就前进道路做出艰难抉择，并且必须持续且专注地沿着这条道路前行。
