Blue hydrogen production from natural gas, plus the added expense of CCS, would cost more than 10 euros per kilogram in March with the soaring natural gas prices. Low-carbon hydrogen is part of the EU plan to diversify its energy supply.

Green hydrogen made of electrolysis from renewable energy is now the preferred choice of future hydrogen supply as governments target net-zero emissions and a reduction of reliance on Russian gas. Scalability and costs are still issues to be overcome in green hydrogen production. Yet, Europe’s dependence on natural gas supply from Russia […]
