Rewire. — Morning Briefing

Signal
Europe is shifting from voluntary hydrogen targets to enforcement mechanisms, with Romania legislating fines for missing its 42% RFNBO goal and Spain simultaneously exhausting its refinery compliance route and tightening additionality rules for data centres via hourly matching. The regulatory hardening contrasts sharply with market softening on the supply side—lithium down 10% in a month on Chinese oversupply—suggesting policy, not economics, is now the binding constraint on the clean-energy transition.

Romanian parliament passes bill fining companies that miss 42% RFNBO hydrogen target by 2030
The Romanian parliament has adopted legislation that would penalise companies failing to source 42% of their hydrogen from renewable fuels of non-biological origin (RFNBO) by 2030, transposing the RED III industry sub-target. The bill sets a financial sanction mechanism for non-compliance. It still requires promulgation before entering into force.

Spain proposes 80% additional-renewables requirement for data centres with hourly matching
The Spanish government has proposed rules requiring data centres of at least 1 MW to source a minimum of 80% of their electricity from additional renewable generation, with hourly matching of consumption and supply. The draft framework also introduces grid access conditions, water-efficiency requirements and EU data-sovereignty provisions. The measure is at the proposal stage.

Siemens Energy to spin off clean-energy unit including electrolysers into new company
Siemens Energy has announced plans to spin off its clean-energy division, which includes its electrolyser business, into a separate company. The move restructures how the group's hydrogen-related activities are organised. Details of the timeline and structure remain to be confirmed.

EU carbon market review: analysts assess implications for climate action
A Carbon Brief Q&A featuring E3G analysts examines what the EU's Emissions Trading System review means for the bloc's climate trajectory. The analysis covers price dynamics, scope questions and the interaction with ETS2 for buildings and road transport. It reflects analyst assessment rather than a formal Commission decision.

Spain nears exhaustion of refinery route for green hydrogen transport quota
An analysis reports that Spain is close to exhausting the refinery-based compliance route for meeting its renewable hydrogen transport quota under RED. The finding implies that additional RFNBO demand will need to come from other sectors or new projects to meet obligations. The assessment is analytical, based on current project pipelines.

Lithium price falls 10% in a month as Chinese supply rises
The cost of lithium for batteries has dropped roughly 10% over the past month, attributed to increasing supply from China. The decline affects input economics for cell manufacturing and storage projects. The figure reflects recent spot-market movement.

Australian researchers report zinc-iodine battery prototype achieving 60,000 cycles in lab
Flinders University researchers, working with industry partners, report a zinc-iodine battery prototype that sustained charge-discharge over 60,000 cycles in laboratory testing. The claim comes from a research announcement and highlights cycle life as the headline metric. Energy density, C-rate, round-trip efficiency, cost and scale-up pathway are not stated.
