Toyota is Considering Natural Gas Fuel Cells

By now most people have heard of hydrogen fuel cells being used in vehicles like the Toyota Mirai to move them around the road without utilizing fossil fuels to do the job. This technology is pretty cool, and it works surprisingly well, but so far it isn’t’ all that practical on a wide-scale. That’s because hydrogen isn’t widely available just yet, and it could be quite a while before there are enough hydrogen refueling facilities to keep cars running all over the world. That’s one of the reasons that Toyota has been toying with the idea of a natural gas fuel cell instead.

Natural Gas Fuel Cell

A Natural Gas Fuel Cell

Just like the hydrogen fuel cell, a natural gas fuel cell would be used to generate electricity to drive a vehicle down the road. The main difference is that it will use natural gas rather than pure hydrogen. The natural gas would be split into hydrogen and carbon monoxide, and both substances would be used to generate electricity for the vehicle. The fuel cell stack on its own will generate electricity at around 53 percent efficiency, but by putting a heat reclaimer in the system Toyota is able to reach efficiency levels around 65 percent, which is better than its current hydrogen fuel cell.

Not as Helpful to Climate change

One of the major criticisms of this new technology is that burning natural gas is not as good for the environment as hydrogen fuel could be if it was produced using renewable resources, and that’s absolutely true. AT the moment hydrogen isn’t being produced with renewable resources though, and it’s being created with fossil fuels. In other words, relying on a natural gas fuel cell over a hydrogen fuel cell could actually be better for the environment currently. That’s because natural gas contributes less to climate change than gas or diesel fuel does. Making the switch to another fossil fuel might not seem like the right move to help mitigate climate change, but at the moment it’s a step that actually makes quite a bit of sense.

Maybe Not for Vehicle Use

While Toyota is experimenting with this new technology, at the moment it only seems like it’s destined for businesses and residential use to generate power for local energy needs. It isn’t being tested for vehicle use just yet, and it’s possible that the tech will never be used in vehicles. Even still, it’s interesting to look at different technologies and ways of doing things.
