Battery Electric Refueling Vehicles
In recent years, the aviation industry has been focusing on reducing its carbon footprint and adopting more sustainable practices. One of the areas of innovation is the development of battery electric refueling vehicles, which are designed to deliver sustainable energy during the refueling process. This adoption of more sustainable technologies is aimed at decarbonizing the aviation industry, meeting future decarbonization targets, and providing more efficient and environmentally friendly alternatives while reducing GHG emissions.
BEVs can be used for a variety of tasks, including refueling aircraft, transporting baggage, and assisting with ground handling operations. One of the primary advantages of battery electric refueling vehicles is their ability to significantly reduce the carbon emissions footprint associated with ground operations at airports.
As the aviation industry seeks to align with global climate goals, finding greener solutions for refueling is of utmost importance. There is a clear interest in using EVs for refueling operations. Aircraft Refueling Decarbonization Options are:
Refueller Technologies: During refueling operations, a significant amount of energy is required for a refueller to transfer fuel from its tank into the aircraft. To improve efficiency and reduce greenhouse gas (GHG) emissions, the use of electrically powered pumping for fuel transfer has been identified as a key solution. Since such batteries would take some time to recharge, One manufacturer has been able to offer a retrofit solution for battery electric refueling equipment that can be installed on existing refuellers, independent of the chassis used. This technology offers valuable GHG emissions savings to existing fleets with the same flow rate as engine-driven pumps, without having to wait for the replacement of vehicles.
Hydrant Dispenser Technologies: A hydrant dispenser is an important equipment that regulates the pressure and flow rate of fuel into an aircraft. Traditionally, the diesel engines of dispenser trucks are kept idling during the refueling process because the dispensing equipment is powered by the engine. However, it is crucial to reduce emissions by enabling fuel dispensing without vehicle engines running. A promising technology for hydrant dispenser vehicles is the use of battery-electric chassis, which eliminates the diesel engine and its associated emissions.
Hydrant Cart Technologies: An alternative approach to refueling that has gained traction is the use of hydrant carts located at each hydrant stand, as opposed to driving hydrant dispenser vehicles. Typically, the electronic control and metering equipment on the cart is powered by a battery charged by a solar panel or, in some cases, a turbine in the fuel flow. It is worth noting that hydrant carts without diesel engines servicing narrow-body aircraft are known to have the lowest overall emissions. However, they are unsuitable for wide-body aircraft that use diesel engines to facilitate their easy movement to the refueling location.
By utilizing electric vehicles for refueling, the dependency on fossil fuels is reduced, leading to a substantial decrease in greenhouse gas emissions.
The benefits of battery electric vehicles (BEV) may include:
- Reducing the total cost of vehicle ownership
- No noise or vibration
- No pollutant emissions from the engine during refueling
- Reduce maintenance
- There may be no need to limit the age of zero-emission vehicles
While there are challenges to overcome, continuous innovation, advancements in battery technology, and the expansion of charging infrastructure hold promise for the future. As the aviation industry strives to reduce its carbon footprint, battery electric refueling vehicles are poised to play a significant role in shaping a greener and more efficient aviation ecosystem.
Disadvantages of Electric Refueling Vehicles (BEV)
While battery electric refueling vehicles offer numerous advantages, they do come with their fair share of challenges. It is crucial to acknowledge and address these limitations to ensure effective integration into the aviation industry.
One of the primary challenges faced by battery electric refueling vehicles is their limited range. Electric vehicles have a finite amount of battery capacity, which, depending on the vehicle and its usage, may not be sufficient for long-distance refueling operations. Furthermore, the availability of charging infrastructure in airports is still limited, making it difficult to recharge vehicles on the go.
Some other disadvantages may include:
- Limited range & charging infrastructure
- Charging time compared to traditional refueling methods
- Expansion of the charging infrastructure and related investments
- Further advancement in battery technologies is needed
One area of ongoing research is the development of advanced battery technologies. Scientists and engineers are working towards the creation of batteries with higher energy density, allowing for longer ranges and reduced charging times. This will be a game-changer for battery electric refueling vehicles and pave the way for their widespread adoption.
The aviation industry is known for its collaborative approach to innovation, and the adoption of battery electric refueling vehicles is no exception. Airlines, airports, and manufacturers are joining forces to develop standards and regulations for the effective deployment of these vehicles. By working together, they can overcome challenges, share best practices, and accelerate the transition toward sustainable refueling practices.
The Power Source for Battery Electric Vehicles (BEVs)
The main power source for BEVs is lithium-ion batteries. These advanced rechargeable batteries store electrical energy chemically, which can then be used to power the electric motor that drives the vehicle. Lithium-ion batteries have become the preferred choice for BEVs due to their high energy density, long cycle life, and fast charging capabilities.
Lithium-ion batteries are made up of several components, including an anode, cathode, and electrolyte. The anode is typically made of graphite, while the cathode is composed of lithium compounds, such as lithium cobalt oxide or lithium iron phosphate. The electrolyte is a conductive solution that allows lithium ions to move between the anode and cathode during charging and discharging.
When a BEV is plugged in to charge, electric current flows into the battery, causing lithium ions to move from the cathode to the anode through the electrolyte. This process is called charging. When the BEV is in use, the lithium ions flow back from the anode to the cathode, releasing electrical energy to power the vehicle. This discharge process propels the electric motor and moves the vehicle forward.
While lithium-ion batteries currently dominate the BEV market, researchers and manufacturers are continuously exploring alternative power sources to further improve the efficiency and sustainability of BEVs. These include solid state batteries and hydrogen fuel cells.
Sustainable Airport Ground Operations
The adoption of Battery Electric Vehicles (BEVs) in airport ground operations offers a multitude of benefits towards achieving sustainable practices. Firstly, the reduction in emissions from these vehicles contributes to cleaner air and helps combat climate change. This is particularly important in airport environments, where air quality can be compromised by the operation of traditional fossil fuel-powered vehicles.
Moreover, BEVs have the potential to improve efficiency in ground operations. With advancements in battery technology, BEVs can now provide longer operating ranges and faster charging times, reducing downtime and increasing productivity. Additionally, the lower maintenance requirements of electric vehicles result in cost savings for airport operators.
Another significant advantage of BEVs in ground operations is the enhanced safety they offer. Traditional fuel-powered vehicles present a higher risk of fire hazards, especially in areas where fuel spills can occur. By eliminating the need for traditional fuels, BEVs reduce the risk of accidents and provide a safer working environment for airport staff.
