“…The produced SNG is likely to find broad application in industrial infrastructure as well as for natural gas grid injection. [40][41][42] Moreover, it could be shown that methanation in two pressure levels has significant advantages compared to methanation in a single pressure level scenario. The benefit of significantly less necessary compression power by changing the process flow arrangement (thesis no.…”

The objective of this article is to demonstrate significant efficiency and performance improvements by simple process modifications of a power to gas plant consisting of high‐temperature coelectrolysis and catalytic methanation. For the advanced process design dual step methanation with two different pressure levels including intermediate compression is proposed, leading to several advantages. By experimental investigations on a lab‐scale methanation test plant higher turnovers (increase of up to 7.1 percentage points) and lower temperature peaks (decrease by up to 130 K) can be proven. Basic energy balance calculations reveal furthermore a reduction in compressor power by 42% for this proposed system.

“… Phase I: The initial scenarios plan hydrogen blending within the gas infrastructure until the theoretical limit of hydrogen concentration of the gas appliances (up to 15%) (Zhao, McDonell, and Samuelsen 2019);  Phase II: In parallel, in order to satisfy major hydrogen consumptions of particular customers, fully hydrogen networks can be developed, also with the capability of connecting with existing gas infrastructures, allowing blending of hydrogen and natural gas;  Phase III: A final phase where the majority of the networks will distribute hydrogen and fewer branches have natural gas in order to satisfy specific customer requirements (high process heat). Adequate planning, construction and operational management of dedicated networks could be the cost-effective solution to assure the hydrogen technical requirements for the predicted end usage scenarios, monitoring and controlling injection in different points of the natural gas existing networks (Gondal 2019).…”

Portugal has developed a national roadmap for hydrogen deployment as a key element of the Portuguese energy transition towards carbon neutrality, with a major contribution towards the electrification of society, generating synergies between the electric and gas systems. Considering the government goals for hydrogen injection within natural gas infrastructures for 2025 and 2030, as long as the indicative trajectories for 2040 and 2050, the authors used the natural gas forecast of the security of supply official report in order to obtain the hydrogen demand and power plant capacity, evaluating the system effort to meet public policy goals. Several alternative scenarios were developed for sensitive analysis, in order to assess the different strategies of hydrogen deployment, considering production from an electrolyzer. Regarding the current Portuguese situation and every scenario outcome, the authors stated that major efforts must be undertaken in order to develop full-scale hydrogen projects in order to meet the national goals.
