![]() ![]() Hydrogen injection using coupled grid and gas network modeling tools. Known as HyBlend, this Department of Energy-funded effort will include techno-economic modeling of Labs to study the impacts of blending hydrogen into natural gas pipeline networks. NREL is collaborating with other national Used to develop fuels-such as synthetic methane or hydrogen-that are then injectedĪnd transported in the gas pipeline network. The links between gas and grid are likely to increase as excess power generation is Hydrogen Blending in Natural Gas Networks Tool (SAInt), with the goal of enabling co-simulation of gas network operations across Interface for the gas network modeling capability in its Scenario Analysis modeling NREL is partnering with encoord to develop an open-source HELICS The Hierarchical Engine for Large-scale Infrastructure Co-Simulation (HELICS) is a co-simulation platform being developed by NREL and other national labs Co-simulation is a means of buildingĬommunication and interaction between these modeling tools while taking advantages Models at a range of operational scales-from power flow analysis to production costĪnd capacity expansion modeling-with gas network models that model transient flowĭynamics and can track gas mixture and quality.Ĭo-Simulation Using the Hierarchical Engine for Large-scale Infrastructure Co-SimulationĪlthough there are many commercial and open-source tools for modeling electric gridĪnd gas network operations independently, there is a need to link these tools to enableīroader analyses of the coupling of these systems. This includes consideration of power sector To that end, NREL is building new modeling tools that represent theĬonnection points between the grid and gas networks with the goal of offering insights Such points of coupling demonstrate the need for modeling that captures the operations Gas infrastructure that was not designed for flexible operation. These ramping requirements may, in turn, increase strain on natural National Grid is focused on building a path to a more affordable, reliable clean energy future through our fossil-free vision. Of variable renewable generation sources is also likely to drive more ramping from National Grid (NYSE: NGG) is an electricity, natural gas, and clean energy delivery company serving more than 20 million people through our networks in New York and Massachusetts. To operate, which creates a feedback loop during times of stress. Underground gas storage, and extraction facilities may rely on electricity supply East CoastĪnd the 2021 Texas freeze, illustrate how constraints in natural gas delivery systemsĬan propagate into power disruptions and outages. Winter storms, such as the 2014 polar vortex on the U.S. Although these linkages can bring operational benefits, they also pose Electric grids and natural gas networks have become increasingly interdependent in ![]()
