Rewire. — Morning Briefing
Wednesday   23 Sep 2026 · Nº 266
Signal
Europe's decarbonisation capital is flowing decisively toward proven demand-side and storage plays—Germany's Carbon Contracts for Difference auction blew past its €5bn budget, CATL began cell production in Hungary, and RWE and Giga Storage pushed gigawatt-hour battery projects—while hydrogen faces a credibility crisis over a contested leaked Commission document. The contrast is stark: batteries and industrial CfDs are attracting oversubscribed money and physical buildout, whereas the hydrogen sector is still fighting over regulatory definitions and public messaging.
AI-generated illustration: a cloakroom that keeps issuing tickets long after its hooks are full — the counter welcomes everyone, the capacity behind it is three pegs, so the queue's coats become a heap.

Germany's latest Carbon Contracts for Difference auction oversubscribed past €5bn budget
According to Hydrogen Insight, Germany's most recent Klimaschutzverträge (Carbon Contracts for Difference) auction attracted bids exceeding the roughly €5bn allocated for the round. The scheme pays industrial operators the difference between conventional and low-carbon production costs to support decarbonisation of processes including hydrogen use.

Ørsted CEO enters German dispute over returning unwanted offshore wind sites
Recharge News reports that Ørsted's chief executive has intervened in a German debate, arguing that around 16GW of offshore wind sites developers no longer want should be re-tendered to unblock the project pipeline. The comments come amid wider controversy over Germany's offshore auction design.
