ROLE OF LNG IN AN OPTIMIZED HYBRID ENERGY NETWORK
PART I. Increased operational flexibility for the future energy system
by integration of decentralized LNG regasification with a CHP
Introduction
• Future energy system needs operational flexibility to support
intermittent renewable energy sources.
• HEN, integration of the independent infrastructures with high
exergy efficiency possible increase of operational flexibility.
• Increase applications of integrated energy systems with LNG,
which has a high exergy value due to the low temperature
Could the integration of decentralized LNG regasification
with a CHP offer additional operational flexibility for the
future energy network with increased intermittent
renewable energy sources, under exergy efficient
conditions?

Conclusion
1. An independent system can guarantee high operational flexibility, meeting
both electricity and Heat demand, but with low exergy efficiency.
2. An integrated system such CHP, offers high exergy efficiency, but the
operation flexibility is compromised, only one commodity can be met.
3. The integrated system with LNG offers and increase of exergy efficiency and
additional operational flexibility, depending on its availability to produce
additional energy carriers and on the means of integration.
