A recent study conducted by Aurora Energy Research on behalf of energy company EnBW in Germany has revealed insights into the potential cost savings of achieving climate-neutral electricity by 2045. The study suggests that by realigning expansion targets for renewable energies and shifting focus to blue hydrogen, Germany could save up to 700 billion euros. The emphasis on blue hydrogen over green hydrogen is highlighted as a cost-effective strategy, with blue hydrogen being significantly cheaper due to its production from natural gas. While green hydrogen is produced from renewable sources, blue hydrogen is generated from natural gas with captured and permanently stored CO2. The study recommends a reduction in offshore wind power targets, halving battery capacities, and significantly decreasing the planned output of electrolysers. Additionally, there is a proposal to increase the use of imported blue hydrogen to operate gas-fired power plants, potentially compensating for reduced offshore wind capacity. The overall sentiment of the article is positive, emphasizing the potential for cost reductions, acceleration of electrification, and decreased burden on the economy through strategic energy system realignments.
