Design takeaway

When designing for heavy-duty transport and aviation, prioritize energy carriers with high energy density, such as liquid fuels, to overcome the limitations of current battery technology.

How to apply

When specifying powertrains for trucks, ships, or aircraft, evaluate the energy density of available low-carbon fuels against the required operational range and payload capacity.

Project actions

  • +Analysis across three major transport sectors.

Limitations

The cost and availability of new fuels and the infrastructure to support them are not always predictable.

Reliability & validity

The study's validity relies on the accuracy and comprehensiveness of the reviewed literature. Reliability is supported by the systematic assessment criteria used for each energy carrier.

Think critically

While liquid fuels offer advantages in energy density, what are the potential environmental and safety trade-offs compared to electrification, and how might these be mitigated in future designs?

05

Design Principles

"Energy density is a critical design parameter for sustainable heavy transport and aviation solutions."

Designers and engineers in the transport sector must consider the physical constraints of energy storage when developing sustainable solutions. Prioritizing energy-dense fuels allows for greater payload and range, crucial for heavy-duty applications and long-haul flights, thereby accelerating the transition away from fossil fuels.

06

What This Means for Your Design

For big vehicles like ships and planes, batteries are too heavy and don't last long enough. Liquid fuels like methanol or special 'power-to-liquid' fuels are better because they pack more energy into a smaller, lighter package.

How to use in your project

  • 1.Use this research to justify your choice of energy source for a vehicle design, especially if you are designing for heavy transport or aviation.
