Which way the wind blows

On March 20th this year, just as this issue was going to print, the UN Intergovernmental Panel on Climate Change (IPCC) issued its Synthesis Report, one of its 5-7 yearly comprehensive assessments of how the world’s climate is changing and what needs to be done to ameliorate it. In spite of all of the progress that has been made since the 5th Synthesis Report in 2017, the IPCC notes that: “the pace and scale of what has been done so far, and current plans, are insufficient to tackle climate change.” While the body believes that keeping warming to 1.5°C above pre-industrial levels is still possible, it is not likely unless work to decarbonise proceeds more rapidly. In particular, the IPCC suggests that CO2 and equivalent emissions need to fall by 43% by 2030 compared with 2019 values, and 60% by 2035 to achieve this goal.

Sizing hydrogen storage for green ammonia

Due to the inherent nature of the renewable power, sizing eSyngas plants powered with renewable energy brings complexity normally not faced by natural gas-based facilities. In this article, Dr Raimon Marin and Dr Solomos Georgiou of AFRY discuss the application of AFRY’s state-of-the-art modelling tool to optimise the size and production of a green hydrogen system and a green ammonia plant based on given renewable power profiles and their associated variability (e.g., hourly, daily, seasonally, and annually).

Decentralised small scale methanol plants

Air Liquide presents the results of an internal study to identify preferred natural gas-based plant configurations at a methanol capacity of 250 t/d. Delivering small capacity plants requires a focus on the total cost of ownership (TCO) for the economics to be successful, in addition to the CO 2 footprint of the operation. As found by this study, SMR concepts are naturally power balanced for standalone greenfield operations and show no particular advantage for power import in a brownfield setting. POX and ATR cases are greatly improved and even advantaged in a brownfield setting compared to SMR when shifting from power balance to power import cases.
