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

• 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

Energy Hub concept

Minimal Imbalance optimization

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.

System Integration Scenarios

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?
