A few middlemen and all is well.
That or when enough time has passed after the war.
We don't have a problem with Saudi Arabian oil, no matter what happened with Kashoggi, Yemen or Raif Badawi.
That pipeline ends on the north coast of Germany. Its customers will have to be in 10-20 countries surrounding Germany, and energy sources are long-term decisions made by boards of directors rather than mid-level managers. Consider the next five years. Which energy company board in those countries is going to discuss two suggested investment plans, one that involves Gazprom and one that involves anything else, and pick Gazprom over an alternative?
Too many resources come from non democratic countries with a lack of human rights.
Which is the case.
> What's the value of a pipeline if the only product it carries is that unpopular?
The value is in having options.
Reducing gas usage is entirely different topic, it would require to either: invest heavily in nuclear or: reopening of coal-powered plants.
LNG is that masses will be expensive and environmental harmful because of the transportation by ship.
This pipeline has an expected lifetime of around 50 years. The availability or non-availability of other power sources this year doesn't matter very much for the valuation of the pipeline. My assumption is that the current political situation will lead to a stronger push towards other energy sources, chiefly renewables but also LNG. And as a consequence, that this will depress the use of the pipeline for at least 45 of its expected 50-year lifetime. With obvious implications for its present valuation.
