Clean Energy Management in Ports
EFFORTS results
Le Havre – March 10th, 2010
A few definitions
• Energy source = primary energy– Fossil fuels, nuclear, solar, wind, tidal, geothermal etc.
• Energy chain– Primary energy secondary energy final energy useful energy– Transformation technologies in between each energy step
• Energy scenario examples: – Oil barrel at 70 $/bbl, no carbon tax, high public acceptance for wind energy– Oil barrel at 130 $/bbl and €50 carbon tax and low public acceptance for
wind energy– Carbon free port

Context
Ports challenges: now and in the future
• Increase in environmental obligations (gas emissions, waste management, etc.)
• Increase of constraints when facing port activities with human environment
• Energy price increase
To face these challenges, the following options must be considered in this order:
1. Save energy2. Increase energy chain efficiency3. Switch to cleaner energy sources4. Consume energy when it is available cheaply and / or from a carbon-
free source (i.e. real-time management)
Attitude change facing the actual situation
Environmental protection is at the core of the project
There are multiple solutions
Organizational System Technological
What are the best energy choices in 5 and 20 years ?
Increasing environmental constraints
Implies modifications
- Societal
- Regulatory
- Market
- Security of supply
More complex needs:
What are the characteristics of my consumption (expressed in useful energy) ?
Should the energy be bought, transformed on site, co-generated, temporarily stored … ?
How to reduce my carbon footprint ?
Objective of Clean Energy Management
To study and establish energy choices on the medium and long term using a decision support tool
It will:
• Increase awareness concerning the energy issue
• Help establish an energy procurement and investment policy
• Valuate local renewable energy sources and waste energy potential
• Check the adequacy of an energy chain (Supply Demand)
• Create a greenhouse gas reporting tool
• Assess energy scenarios breaking with current practices and provide arguments to support the choice of scenario

Methodology of Clean Energy Management
Energy Supply
Primary energy
Global / national supply:Grid powerFossil fuels (diesel, LPG…)
Regional supply:Renewable energies (wind farms, sea energies, biomass…)And other sources
Local supply: Waste incineration or methanisationRenewable energies (solar, individual wind turbines …)

Conclusion
Current and future projects dealing on energy and environment issues
• Energy management– Sustainable port application:
EFFORTS continuity: Focus on storage policy and non-electric energy
– Sustainable city application: Extension of EFFORTS project methodology to sustainable cities focusing on
urban area development and mobility
• Real-time management, focus on:– Hybrid equipment development– Data input from a terminal operating system (TOS)– …
