Electric vehicles are gaining in popularity around the world, especially with the high cost of fuel. But some of the current EV models aren’t a good fit for owners who can’t wait around for hours for their batteries to charge, such as taxi drivers, delivery people, and ride-hailing services.

One startup trying to solve this problem is ARC Ride, in Nairobi, Kenya.

Among the technological visions that seem perpetually futuristic (think commercial nuclear fusion and maglev trains), the hydrogen economy has always been tantalizing. Hydrogen produced from renewable energy or nuclear power, with minimal greenhouse-gas emissions, could be piped or transported pretty much anywhere, using mostly existing infrastructure. It could power trucks, cars, planes, and ships and generate electricity, either in fuel cells or combustion turbines. In short, it could do anything fossil fuels do now, but with substantially reduced climate impact.

Now, after decades of false starts and overly optimistic projections, several factors are giving an unprecedented lift to clean hydrogen. In the United States, sweeping legislation capped a series of moves by the country’s Department of Energy (DOE) over the past year to drive down the cost of low-carbon hydrogen and stimulate demand for the fuel. And in Europe, a looming fossil-fuel crisis has sent officials scrambling to find alternatives to the 155 billion cubic meters of Russian natural gas that EU countries imported in 2021.

Fuel cell electric vehicles (FCEVs) often reach higher energy density and exhibit greater efficiency than battery EVs; however, they also have high manufacturing costs, limited service life, and relatively low power density.

Modeling and simulation can improve fuel cell design and optimize EV performance. Learn more in this white paper.
