Rewire. — Morning Briefing
Thursday   17 Sep 2026 · Nº 260
Signal
Corporate demand and industrial policy are converging on green steel and batteries as the credible near-term decarbonization plays—Google's 91,000-tonne green steel certificate purchase and Salzgitter's solar-plus-storage PPA show buyers moving on abatement that pencils out today. Hydrogen, by contrast, faces mounting scrutiny, with Spain openly questioning the economics of the EU's 2030 refuelling build-out even as a $735m South African e-SAF FID bets on the niche where hydrogen has fewer substitutes.
AI-generated illustration: book-and-claim as a detachable shadow: two identical billets, but the single shadow is being slid from under one to under the other, so cleanliness becomes a thing you can hand over while the metal stays put.

Google buys certificates for up to 91,000 tonnes of hydrogen-based green steel from Stegra
Google has agreed to purchase environmental attribute certificates covering up to 91,000 tonnes of green steel produced via hydrogen direct reduction from Swedish producer Stegra (formerly H2 Green Steel), according to Hydrogen Insight. The arrangement is a book-and-claim style purchase of the emissions benefit rather than physical steel offtake.

Spain questions economics of EU hydrogen refuelling build-out ahead of 2030 deadline
Spain has publicly raised doubts about the economic viability of the EU-mandated roll-out of hydrogen refuelling infrastructure as the 2030 AFIR deadline approaches, according to Hydrogen Insight. The concerns centre on weak demand and the cost of stations required along the TEN-T network.

Zelestra and Salzgitter sign German solar-plus-storage PPA for steelmaking
Developer Zelestra and steelmaker Salzgitter Flachstahl have signed a power purchase agreement for a new solar-plus-storage portfolio in Germany to supply the company's steel production, according to Energy-Storage.news. The deal pairs solar generation with battery storage to firm renewable supply for an industrial offtaker.

Strategy paper argues batteries are Europe's industrial and defence backbone
A strategy paper covered by CleanTechnica argues that batteries underpin Europe's future energy system, industrial base and defence readiness, noting that the bloc is embedding storage across systems at record pace while producing almost none of the key inputs and relying heavily on public subsidy. The paper frames the input-dependency gap as a strategic vulnerability.
