What are the technical barriers to blending hydrogen into the natural gas network? How well will the pipelines cope? How will the blend affect equipment and appliances? What are the costs and environmental impacts? The answers to these key questions are being sought by a collaboration of laboratories, industry and academia led by NREL, called HyBlend. The long-term impact of hydrogen on materials and equipment is still not understood. The effect on the lifetime of pipeline materials, emissions, costs, as well as alternative pathways (such as synthetic natural gas) all need to be known before operators can commit to using hydrogen-gas blends at scale.
