The majority penetration of Variable Renewable Energy (VRE) will challenge the stability of electrical transmission grids due to unpredictable peaks and troughs of VRE generation. With renewable generation located further from high demand urban cores, there will be a need to develop new transmission pathways to deliver the power. This paper compares the transport and storage of VRE through a hydrogen pipeline to the transport of VRE through a High Voltage Direct Current (HVDC) transmission line. The analysis found a hydrogen pipeline can offer a cost-competitive method for VRE transmission compared to a HVDC transmission line on a life-cycle cost basis normalized by energy flows for distances at 1000 miles with 2030 technology. This finding has implications for policy makers, project developers, and system operators for the future development of transmission infrastructure projects given the additionality which hydrogen pipelines can provide in terms of energy storage.

由于VRE产生的不可预测的波峰和波谷，可变可再生能源（VRE）的大部分渗透将挑战输电电网的稳定性。随着可再生能源发电远离高需求城市核心，将需要开发新的传输路径来输送电力。本文将VRE通过氢气管道的运输和存储与VRE通过高压直流（HVDC）传输线的运输进行了比较。分析发现，在2030年技术中，以生命周期成本为基础，氢气管道可以为VRE传输提供具有成本竞争力的方法，而HVDC输电线路的寿命周期成本是通过能量流对1000英里的距离进行标准化的。这一发现对政策制定者，项目开发者，
