Penspen, a UK-based engineering firm, has secured a contract to conduct a hydrogen gap analysis on the Trans Adriatic Pipeline (TAP) in southern Europe. The purpose of the analysis is to assess the feasibility of introducing hydrogen blends into the existing natural gas pipeline infrastructure. TAP, spanning 877km from the Greek-Turkish border to Italy, is considering hydrogen integration to support capacity expansion, sustainability, and regional decarbonisation goals. While the exact blending ratio has not been disclosed, TAP's Transmission System Operators (TSOs) conducted an Initial Hydrogen Readiness study in 2021 as part of their exploration. The Managing Director of TAP, Luca Schieppati, expressed optimism about the potential for the pipeline to significantly contribute to Europe's carbon neutrality ambitions through hydrogen blending with natural gas. Penspen will evaluate the readiness of TAP's above-ground installations, block valves, and compressor stations for hydrogen blending, aiming to support the delivery of cleaner energy to communities. Penspen's Energy Transition Director highlighted the importance of assessing existing infrastructure for hydrogen blends, emphasizing the role of strategic transportation systems in regional decarbonisation efforts. The contract with TAP follows Penspen's collaborations with other European operators, such as the Latvian Conexus Baltic Grid and a Portuguese TSO, to explore hydrogen blending feasibility and readiness assessments. The article also discusses the concept of hydrogen blending as an interim step towards reducing emissions in natural gas grids. Blending hydrogen with natural gas allows for emission reduction while utilizing existing infrastructure, presenting opportunities in various applications like boilers and industrial processes. Policy-led projects across different regions are exploring the potential of blending hydrogen as a transitional solution for lowering emissions in the short term, highlighting the growing interest in cleaner energy alternatives.
