'Universal' faith in hydrogen could lock world into fossil fuel reliance: German study

Hydrogen should be reserved for focused use in decarbonising air travel and the world’s heavy-emitting industries or it could lock the world in to longer-term fossil fuel reliance and drive up greenhouse gas (GHG) emissions, according to a new German study.
Researchers at the Potsdam Institute for Climate Impact Research (PIK) concluded that hydrogen should only be used in sectors that “cannot be electrified” as production of the carrier is still “too inefficient, costly and [its] availability too uncertain, to broadly replace fossil fuels” in running cars or heating homes.
“For most sectors, directly using electricity for instance in battery electric cars or heat pumps makes more economic sense. Universally relying on hydrogen-based fuels instead and keeping combustion technologies threatens to lock in a further fossil fuel dependency and GHGs,” said PIK’s Falko Euckerdt, who lead the stud ....

Hydrogen's "false promise" could hamper climate progress, lock in fossil fuels


7 May 2021
A new study has warned that a universal reliance on hydrogen-based fuels could hamper – rather than boost – the global climate effort, by distracting from the main game of renewable electrification and locking in longer-term fossil fuel dependency.
The study from the Netherlands-based Potsdam Institute for Climate Impact Research (PIK) says that while renewable hydrogen will play an important role in a low-carbon future, producing it remains too inefficient, costly and uncertain to broadly replace fossil fuels.
The researchers argue that hydrogen-based fuels should be prioritised for use in applications for which they are “indispensable;” those that are tough to electrify, such as long-distance aviation, feedstocks in chemical production, steel production and some industrial processes. ....

German Chancellor Angela Merkel attends the 12th meeting of the Petersberg Climate Dialogue conference on May 6, 2021 in Berlin.
German Chancellor Angela Merkel’s acknowledgement of the elephant in the room at the climate summit she convened this week came so subtly the average listener could easily be forgiven for missing it. Squeezed between a welcome message and a new commitment to accelerate her country’s climate goals, Merkel mentioned Germany’s high court had ruled against her government’s 2019 climate law for not going far enough to protect future generations. ....
