US CBAM backer defeated - Senator Bill Cassidy (R-LA), the most vocal Republican proponent of a US carbon tariff, was defeated in his party's primary process in his effort to win re-election, Axios reported. Cassidy had been accused of "disloyalty" by President Donald Trump, who backed one of Cassidy's challengers, Representative Julia Letlow, who has advanced to the two-candidate runoff. In a client note, analysts at Washington DC-based research firm ClearView Energy said Cassidy's defeat could mean a proposal for a federal carbon tariff under a Republican-controlled Congress is much less likely to succeed, or it could mean the Trump administration may be willing to give such a policy another look now that the issue is not necessarily associated with Cassidy.

Hydrogen alliance - The Zero Emissions Ship Technology Association (ZESTAs) has launched a new platform - the Global Liquid Hydrogen Alliance - designed to advance pure green hydrogen and liquid hydrogen as a scalable and commercially viable zero-emission shipping fuel. Its aim is to convene organisations ready to build the liquid hydrogen value chain, in order to support the more than 600 hydrogen projects announced globally, backed by over €175 bln in committed investment. The alliance is open to companies across the value chain, and aims to position liquid hydrogen as a primary energy carrier for shipping - to accelerate creation of the $45 bln liquid hydrogen market and turn policy into deployment, said the press release Monday. This is in line with ongoing plans to develop a global carbon price for shipping under the IMO's Net Zero Framework that remains intact following recent negotiations.
