AI Customer ServiceIn the ongoing pursuit of greener energy sources, lithium-ion batteries and hydrogen fuel cells are two technologies that are in the middle of research boons and growing public interest. The li-ion batteries and hydrogen fuel cell industries are expected to reach around 117 and 260 billion USD within the next ten years, respectively.
On the surface, it can be tempting to argue that hydrogen fuel cells may be more promising in transport, one of the key applications for both technologies, owing to their greater energy storage density, lower weight, and smaller space requirements compared to lithium-ion batteries.
As such, lithium-ion batteries are now a technology opportunity for the wider energy sector, well beyond just transport. Electrolysers, devices that split water into hydrogen and oxygen using electrical energy, are a way to produce clean hydrogen from low-carbon electricity.
Hydrogen-powered vehicles can also be refuelled more quickly than vehicles powered with lithium-ion batteries.
A fuel cell generates electricity from hydrogen (H 2) and oxygen (O 2), whereas lithium-ion battery stores and supplies electricity and requires an external source for charging. As shown below, the fuel cell is always coupled with a hydrogen tank and a lithium-ion battery in an EV.
