Adaptive energy ecosystems - improved operability, efficiency and economics for electricity and gas infrastructure

电网与天然气分配/储存基础设施的融合增加了管理间歇性可再生能源供应的灵活性。可再生天然气、电力到天然气（PtG）和其他基于天然气的能源存储解决方案提供了改善剩余非高峰电力和间歇性可再生能源的经济和技术管理的能力。新的适应性基础设施，如电解槽，可以同时稳定电网、季节性储存大量电力、地理传输能源和分布式可再生能源的可调度再生。这是通过连接电力和天然气管道基础设施来实现的。这在短期内是有潜力的，因为许多现有的能源基础设施已经存在。可再生气体，如PtG将可再生能源转化为氢气，只是优化现有的天然气分配和电力网络能力，以限制浪费和出口，为安大略省收获更多的可再生能源。在这个项目中，将探索各种模型，以确定关键气体生成组件的大小和位置，并评估对天然气分配系统的影响，例如系统中不同时间点（即一天中的时间和一年中的时间）产生的氢气浓度。将开发“能源中心”模型，其中能源中心是以各种形式转换和储存能源的技术中心。除了经济和环境效益外，优化现有基础设施还会增加公众对能源问题的接受度，因为新建能源基础设施的压力会减少。改进的可再生能源整合规模可能在太瓦时范围内，提供非常引人注目的环境收益。除了经济和环境效益外，优化现有基础设施将减少公众对能源问题的反对，因为新建能源基础设施的压力减少了。

The convergence of the electrical grids with the natural gas distribution/storage infrastructure increases the flexibility for managing intermittent renewable supplies. Renewable Natural Gas, Power-to-Gas (PtG) and other gas-based energy storage solutions offer the ability to improve the economic and technical management of surplus off-peak power, and intermittent renewable energy. New, adaptive infrastructure like electrolyzers allows simultaneous grid stabilization, seasonal storage of bulk power, geographic transmission of energy and dispatchable regeneration of distributed renewable energy. This is achieved by bridging the electricity and gas-pipeline infrastructure together. This has near-term potential because much of the existing energy infrastructure exists. Renewable gases, like PtG conversion of renewable power to hydrogen, is just optimizing the existing gas distribution and electricity network capabilities to limit waste and exports to harvest more renewable energy for Ontario. In this program various models will be explored to size and site the key gas generation components, and assess the implications to the natural gas distribution system such as the resulting concentration of hydrogen a various points and times (i.e. time of day and time of year) in the system. Models for 'energy hubs' will be developed, wherein an energy hub is a center of technologies that transform and store energy in various forms. In addition to the economic and environmental benefits, optimizing existing infrastructure will result increased public acceptance on energy issues as pressure for new-build energy infrastructure is reduced. The scale of improved renewable energy integration is potentially in the TWh range offering very compelling environmental gains. In addition to the economic and environmental benefits, optimizing existing infrastructure will result in less public push-back on energy issues as pressure for new-build energy infrastructure is reduced.
