EU green hydrogen rules will drive up emissions, new report suggests

illuminem summarises for you the essential news of the day. Read the full piece on Euractiv or enjoy below:

🗞️ Driving the news: A recent report cautions that EU rules meant to certify “green hydrogen”— specifically the mandates on additionality, timing, and location — could inadvertently raise overall greenhouse gas emissions
• These regulations may force power grids to rely on fossil-based backup generation or create perverse incentives, undermining the climate benefits of hydrogen production

🔭 The context: The EU's Renewable Energy Directive requires hydrogen electrolyzers to run on newly built renewable sources that are temporally and geographically grid-matched — a set of criteria meant to guarantee true decarbonization
• But studies now show these constraints could delay scale-up, raise system costs, and trigger higher emissions elsewhere.

🌍 Why it matters for the planet: If enforcing strict “green hydrogen” rules leads to grid instability or defers renewable deployment, the net result could be higher emissions sector‑wide
• Scaling clean hydrogen is central to decarbonizing hard‑to‑abate sectors; missteps in policy risk diluting its climate impact and slowing down the transitio

⏭️ What's next: Policymakers must weigh tightening “additionality” rules against risks of slower deployment and unintended emissions
• The European Commission plans further reviews and consultations — possibly revising criteria to balance environmental integrity with scalability ahead of the 2030 climate targets

💬 One quote: “Additionality is the most expensive to comply with but also the most effective in accelerating the transition to renewable power”

📈 One stat: Stricter criteria are projected to increase system costs by €82 billion across Europe between 2024 and 2048
