Urban air mobility seems to have taken a backseat, after a flurry of promises a few years ago. There are several reasons for this, including noise and gas pollution, and keeping urban airspace safe. Electric propulsion seems an ideal approach under these constraints. However, this form of transport would need more powerful batteries for the idea to take off.
Why Urban Air Mobility Needs More Powerful Batteries
Demanding bigger batteries for electric road vehicles aims to improve the product. However, even short electric flights have difficulty taking off without more powerful energy storage. This battery storage also needs to be lightweight, cool, and able to prevent individual cells from overheating.
Electric road vehicle manufacturers have a product that consumes energy relatively steadily. While electric aircraft require a large amount of energy to take off, and far less to keep on flying. They also need a reserve supply to be able to land safely. This implies having more powerful batteries on board.
Aerospace Global News adds a third requirement for urban air mobility to take off. This boils down to quick battery turnarounds at passenger collection and drop-off points. Battery swaps and recharges will have to accommodate this requirement quickly, and cost-effectively too.
Where To From Here With Urban Air Mobility?
Batteries for flying taxis add a set of additional requirements over and above electric travel on the ground. They need to pack more energy. That much is obvious. But more powerful batteries also need be lighter. Every ounce of weight an aircraft carries increases its struggle to overcome gravity.
Going green with urban air mobility presents additional challenges, that most conventional batteries can’t accommodate. This form of transport needs to overcome these issues with lighter, more efficient, and more powerful batteries. Until we satisfy these criteria, electric aircraft will remain a dream for now.
