The pilot in port of Livorno:
Adaptation of a Reach Stacker vehicle to a different motorization for reducing
environmental impact and energy consumption.
PILOT PHASES:
Design of a Reach Stacker that adopts
alternative environmental compatible
fuelling (i.e. LNG or hydrogen cells)
Integration and realization of a
prototype according to the design
Functional testing of the prototype
Pilot of the prototype and analysis of
performance in a real PCT

Activity 3. Pilot and Demonstration: adaptation of a diesel Reach Stacker to a dual fuel engine.
Dual-fuel solution has many advantages: • Installation is not invasive and the system is reversible. • Reach Stacker can operate at 100% diesel fuel, so is not “LNG refueling station
dependent”. • It does not reduce the original performances of the reach stacker. • Compared to the CNG solutions it requires a smaller LNG tank volume:
• Reduces the GHG and other pollutants emissions. • Good results under cost-benefits aspect point of view (operating fuel costs
saving). • Safety of LNG compared to CNG and H2. • Possible easy conversion of reach stacker fleet to dual fuel systems. • The payback period will be 7 years and IRR will be 11.89%.

Dual Fuel
• the dual fuel powered engine does not show any decrease of power compared to diesel, even at maximum load;
• Diesel substitution rate varies from 60% at low rpm to 35% at high rpm (at the maximum load).
• the oil temperature, the exhaust temperature, the intake manifold pressure and LAMDA don’t show significant differences between the dual fuel powered engine and the diesel powered engine;
Activity 3. Pilot and Demonstration: Compared tests covering the whole operating cycle.
