Not a 'panacea': UK lawmakers play down hydrogen's role in net-zero shift

Hydrogen has a portion to play successful the U.K.'s displacement to a net-zero system but its relation volition apt beryllium restricted to definite sectors, according to a report from an influential committee of U.K. lawmakers.

The House of Commons Science and Technology Committee concluded that though hydrogen possessed "several charismatic features, astir of the grounds we person received was wide that with existent technologies, it does not correspond a panacea."

"As the UK looks to modulation to a Net Zero economy, hydrogen volition apt person circumstantial but constricted roles to play crossed a assortment of sectors to decarbonise wherever different technologies — specified arsenic electrification and vigor pumps — are not possible, practical, oregon economic," the report, which was published Monday, said.

Described by the International Energy Agency arsenic a "versatile vigor carrier," hydrogen has a divers scope of applications and tin beryllium deployed successful a wide scope of industries.

One method of producing hydrogen uses electrolysis, a process done which an electrical existent splits h2o into oxygen and hydrogen.

Some telephone the resulting hydrogen "green" oregon "renewable" if the energy utilized successful the electrolysis process comes from a renewable root specified arsenic upwind oregon solar. The immense bulk of hydrogen procreation contiguous is based connected fossil fuels.

Monday's study sought to temper expectations astir the relation hydrogen could play successful slashing emissions and the modulation to a net-zero economy.

"To marque a ample publication to reducing greenhouse state emissions successful the UK, the accumulation of hydrogen requires important advances successful the economical deployment of CCUS [carbon capture, utilization and storage] and/or the improvement of a renewable-to-hydrogen capacity," it said.

"The timing of these is uncertain, and it would beryllium unwise to presume that hydrogen tin marque a precise ample publication to reducing UK greenhouse state emissions successful the short- to medium-term."

Committee seat Greg Clark said that determination were "significant infrastructure challenges associated with converting our vigor networks to usage hydrogen and uncertainty astir erstwhile low-carbon hydrogen tin beryllium produced astatine standard astatine an economical cost."

"But determination are important applications for hydrogen successful peculiar industries truthful it tin be, successful the words of 1 witnesser to our inquiry, 'a large niche'," Clark added.

Industry radical Hydrogen Europe did not instantly respond to a CNBC petition for comment.

Big plans, large challenges

Over the past fewer years, large economies and businesses person looked to the emerging greenish hydrogen assemblage to decarbonize industries integral to modern life.

During a roundtable treatment astatine the COP27 clime alteration acme past month, German Chancellor Olaf Scholz described greenish hydrogen arsenic "one of the astir important technologies for a climate-neutral world."

"Green hydrogen is the cardinal to decarbonizing our economies, particularly for hard-to-electrify sectors specified arsenic alloy production, the chemic industry, dense shipping and aviation," Scholz added, earlier acknowledging that a important magnitude of enactment was needed for the assemblage to mature.

"Of course, greenish hydrogen is inactive an babe industry, its accumulation is presently excessively cost-intensive compared to fossil fuels," helium said. "There's besides a 'chicken and egg' dilemma of proviso and request wherever marketplace actors artifact each other, waiting for the different to move."

Also appearing connected the sheet was Christian Bruch, CEO of Siemens Energy. "Hydrogen volition beryllium indispensable for the decarbonization of ... industry," helium said.

"The question is, for america now, however bash we get determination successful a satellite which is inactive driven, successful presumption of business, by hydrocarbons," helium added. "So it requires an other effort to marque greenish hydrogen projects ... work."
