Aligning EU energy security and climate mitigation through targeted transition strategies

Area of Science:

• Energy Systems Analysis
• Climate Change Mitigation
• Renewable Energy Policy

Background:

• The European Union faces significant energy security risks due to its dependence on fossil fuels, exacerbated by climate change and geopolitical instability.
• Decarbonization efforts are crucial for meeting climate targets, but must be balanced with the need for a secure and stable energy supply.

Purpose of the Study:

• To evaluate coordinated strategies for expanding renewable energy sources and green hydrogen production in the European Union.
• To assess the impact of these strategies on energy security, decarbonization, and economic outcomes through 2050.

Main Methods:

• Utilized a forward-looking energy systems framework to develop strategic scenarios for the European Union's energy system up to 2050.
• Analyzed the implications of integrated wind and solar power expansion, green hydrogen, and carbon offsetting on natural gas consumption and emissions.

Main Results:

• Coordinated expansion of wind and solar power can reduce gross inland natural gas consumption by up to 61.3%.
• Green hydrogen production can decrease gross inland natural gas consumption by up to 37.0%.
• These strategies align energy security objectives with climate change mitigation goals.

Conclusions:

• Targeted policies, including incentives for renewable energy deployment, are essential for reinforcing European Union energy security.
• The integration of renewable energy and green hydrogen offers a viable pathway to achieve both climate benefits and enhanced energy security amidst geopolitical challenges.
