Decarbonising Logistics with HAVI

The eCool Partnership - HAVI Portugal’s Journey in Decarbonising Transport Refrigeration

HAVI Portugal's commitment to innovation and sustainability is at the heart of its operations. In partnership with Addvolt, Carrier Transicold Portugal, and Grupo Ferramacho, HAVI tested a fully electric refrigerated semi-trailer equipped with the Vector eCool system. This project aims to transform inter-centre transportation, ensuring the best possible quality for the distribution of thermo-sensitive goods between the last-mile distribution hub in Algarve, Portugal and the distribution centre in Azambuja, Portugal.

Challenges with the Traditional System

Traditional refrigerated goods transportation relies on a secondary diesel engine exclusively dedicated to the refrigeration process. These engines, often classified as EURO 2, are responsible for significant emissions of carbon dioxide (CO2) and harmful particles (NOx), as well as generating high noise levels. All these factors are detrimental to public health and the environment in communities affected by the transport and distribution of goods.

The Solution: Electrification of Refrigerated Transport

Saying goodbye to the diesel engine was a natural step in HAVI’s journey towards sustainability. To tackle these challenges, a solution was tested to eliminate this extra diesel engine and electrify the refrigeration process during goods transportation – with the Vector eCool system, the first fully electric refrigeration system for semi-trailers. This system comprises a fully electric, engine-less refrigeration unit powered by an Addvolt Powerpack (energy storage system with integrated power electronics for energy management) and a generator axle (energy recovery system).

This innovative solution converts the kinetic energy generated by the axle with the trailer's movement into electricity, storing it in the Powerpack batteries that power the refrigeration unit. Thus, we eliminate the need for fossil fuels and consequently the emissions of CO2 and NOx.

Autonomous Energy Operations Between Centers

The electric semi-trailer was used on the route between HAVI's last-mile distribution hub in the Algarve and their distribution centre in Azambuja. During this journey, the generator axle of the Vector eCool system ensured the regeneration of the necessary energy to maintain the constant refrigeration of the thermo-sensitive goods without compromising their quality.

The generator axle converts the kinetic energy generated during the trailer’s driving into electricity, which is then stored in the Powerpack (battery pack) to power the refrigeration unit. This energy cycle provides autonomy for logistics operations, with zero CO2 emissions and no NOx particles. Also, this system can be connected to the electrical grid when the semi-trailer is parked at the logistic centre, making the operation even more flexible and efficient.

Promising Results

The performance of the electric semi-trailer was monitored in real-time through My Addvolt. This to digital platform allows HAVI to obtain real-time data on their fleet, monitoring energy consumption, battery levels, and vehicle performance. With this, they can make more informed decisions, reduce operational costs, and optimize energy use (powerpack, grid, and regenerated energy), ensuring compliance with environmental regulations.

The test results were extremely positive, as highlighted by the following points:

Daily energy usage via MyAddvolt, from sources: grid, solar and regenerated energy

  • Energy Consumption: Almost all the energy used for refrigeration came from axle regeneration, demonstrating the efficiency of the solution Vector eCool (Electric refrigeration unit, Powerpack system, Axle generator).

  • Battery Level: At the end of each trip, HAVI arrived with 80-90% of the battery charge still available, proving this system's autonomy.

  • Diesel Savings: They avoided the consumption of 410 litres of diesel, over a month of operation.

  • Emissions Avoided: They prevented the emission of 1081 kg of CO2, significantly contributing to environmental sustainability and allowing them access to zero-emission zones, known as LEZ (low emission zones) or ULEZ (ultra-low emission zones).

  • Silent Operations: The system is PIEK certified, allowing access to urban centres at any time, especially during nighttime periods.

  • Reduced Maintenance: The absence of a diesel engine reduces the need for traditional oil and filter changes and engine-related problems, increasing vehicle operability, efficiency and availability (less stop times).

Solution Confirmation

"This is the way! Our experience with the Vector eCool system confirmed that the combination of the generator axle and powerpack works efficiently and autonomously. The energy regeneration during driving allowed us to maintain operations without relying on the electrical grid or fossil fuels, creating a significant competitive advantage for HAVI Portugal's logistics."

Sérgio Aderneira, Transport Manager, HAVI Portugal

"The solution works! Implementing innovative and sustainable solutions is essential. HAVI has extensive experience in the process of decarbonizing goods distribution, and we remain committed to innovation and logistical efficiency. The future of logistics necessarily involves environmental and social sustainability, and we are committed to working together for a responsible future."

A Sustainable Future

HAVI started decarbonising its refrigerated fleet in 2016, and this test with Addvolt, Carrier Transicold Portugal, and Grupo Ferramacho was crucial to continue extending the results to other operations. The electrification of heavy-duty transportation has already begun and continues with HAVI Portugal.
