“The sectors were looking to decarbonize with kind of green molecules, so-called green molecules. If you measure them in terms of electrolysis or generating capacity, we're talking multiple terawatts of needed new energy supply, new power supply to cross into those sectors.”

The claim, plainly

Decarbonizing industrial sectors with green molecules requires multiple terawatts of new power supply and electrolysis generating capacity.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

Major global energy transition models unanimously confirm that decarbonizing hard-to-abate industrial sectors with electrolytic green molecules requires multiple terawatts of both electrolyser capacity and dedicated clean power supply. The International Energy Agency (IEA) Net Zero by 2050 Roadmap projects 3.0 to 3.6 TW of global electrolyser capacity by 2050. The International Renewable Energy Agency (IRENA) 1.5°C Pathway projects 5.0 TW of electrolysers requiring 4.5 to 10+ TW of dedicated renewable power capacity. BloombergNEF (BNEF) models 3.0 to 4.0 TW of electrolysis capacity supported by 4.5 to 6.5 TW of dedicated clean power capacity.

IEA Net Zero by 2050 Roadmap projects global installed electrolyser capacity reaching 3.0 to 3.6 TW by 2050, demanding ~14,500 to 15,000 TWh of clean electricity.
IRENA World Energy Transitions Outlook projects 5.0 TW of electrolyser capacity by 2050, requiring 4.5 to 10+ TW of dedicated renewable generation capacity.
BloombergNEF Hydrogen Economy Outlook models 3.0 to 4.0 TW of electrolysis capacity paired with 4.5 to 6.5 TW of dedicated renewable power capacity.

Garabedian: Global electrolytic hydrogen has entered disillusionment mode

“It's not a seller's market in electrolytic hydrogen anymore. At least not for the time being. We've definitely come out of hype mode, and we're in hydrogen disillusionment mode right now, I think, globally.”
