Construction of Nord Stream 2 is now 83%complete but progress has been halted after the U.S. government threatened to impose sanctions on the Swiss pipe laying firm Allseas. Gazprom, the majority owner of the pipeline, vowed to complete the remaining 100-mile stretch with a Russian pipe laying vessel.
Once completed, the Uniper CEO could accept a quota that prescribes that a certain amount of Nord Stream’s throughput should be hydrogen. This measure would help transform wider northern European gas network towards mixing natural gas with hydrogen of any kind.
Green vs. blue hydrogen
The German government aims for global leadership in hydrogen technologies, considered crucial to make the economy carbon-neutral by 2050. However, the national hydrogen strategy has been delayed due to disagreements on targets for making ‘green hydrogen’, and on the extent to which ‘blue hydrogen’ made from natural gas using carbon capture storage (CCS) should be used as a transitional technology.
Advocating the use of ‘blue hydrogen’, Eurogas Secretary General, James Watson, noted that the fuel is likely to replace natural gas in some parts of EU pipeline system. “Instead of transporting only natural gas, Nord Stream 2 could transport 80% of the hydrogen,” he noted, pointing at the EU’s ambitious decarbonization program.
The industry association BDI opposes ruling out the use of ‘blue hydrogen’, arguing that insisting on green hydrogen would delay technology development given that sufficient volumes will not be available by 2030. The economy ministry's February draft of the German hydrogen strategy, seen by the Clean Energy Wire, said that while green hydrogen “is sustainable in the long term,” blue hydrogen “will have to play a role for economic reasons to quickly establish the technology in the market and to decarbonise various areas of application.”
Schierenbeck also said the strategy should include support for specific projects and some kind of national hydrogen market. "We will need both. For example, there is nothing to be said against prescribing that a certain amount of hydrogen is needed in the gas network, i.e. a quota."
