The Aircraft Refueling
In the future, the focus will be on reducing emissions from traditional refuellers and dispensers that are based on commercially available truck chassis. To achieve this, zero-emission powertrains such as battery-electric or hydrogen-fueled systems will be adopted, driven by government policies such as the EU’s requirement to cut CO2 emissions from trucks by 30% by 2030.
In this section, we will explore various options and technologies that can be used to reduce carbon footprint in refueling operations. One of the options is the use of electrically powered pumps for fuel transfer from refuellers and electrically powered hydrant dispensers. These options are aimed at reducing greenhouse gas emissions and making refueling operations more eco-friendly.
Why Electric Fuel Dispensers?
Hydrant dispensers are vehicles that provide fuel through an underground pipe network, known as a hydrant system, at each stand or gate to refuel aircraft. These dispensers regulate the pressure and flow rate of the fuel into the aircraft tanks, typically using under-wing dry break connections.
Battery-electric powertrains are considered a promising technology for hydrant dispenser vehicles. Electric dispenser vehicles eliminate the emissions from diesel engines and offer the benefits of zero local pollutant emissions, reduced maintenance, and quieter operation.
However, the high purchase cost of electric vehicles and the need for charging infrastructure are challenges that need to be addressed.
Electric Refueling Vehicles: Technical Details & Benefits
In the aviation industry, refuellers, also known as bowsers, play a critical role in carrying aviation fuel and pumping it into aircraft. Refuellers come in various sizes, ranging from 5,000 to 80,000 liters of fuel, depending on the aircraft’s tank capacity. Refuelers usually incorporate a pump to transfer fuel from the refueller tank to the aircraft tanks. The pump can be driven either by the refueler’s engine or electric power.
To reduce emissions and achieve decarbonization in refueling operations, several options are being explored. One such option is the implementation of electrically powered pumping for fuel transfer. This option can significantly reduce greenhouse gas emissions. Another option is retrofitting existing refuellers with engine-off refueling capability, which allows the engine to be turned off during refueling, resulting in savings in fuel and a reduction in emissions.
Vehicle weight limitations are critical considerations in the design, operation, and performance of refuellers and their components. Such limitations can affect vehicle efficiency, payload capacity, and overall performance.
Apart from the environmental benefits, electric aircraft refuelers offer various technical advantages. These electric aircraft refueling vehicles have faster refueling times, which reduces aircraft turnaround times and enables more efficient operations.
Electric aircraft refueling vehicles require fewer maintenance checks and have fewer mechanical parts to replace, which results in lower maintenance costs over time.
