Scientists are constantly working on a non-fossil fuel transportation option. With America’s high dependence on traveling by car, there is a reason to believe they will find successful options within the next few years. The demand is certainly there so science is such to catch up eventually.

One of the newest methods involves recycling all the carbon dioxide wasted in the production of biofuels. This would make the process more efficient and scientists believe it would offer enough fuel to power cars all over America.

The hybrid hydrogen-carbon process could essentially make diesel fuel from coal or biomass, without putting carbon dioxide into the atmosphere. Because biofuels can lose CO2 into the atmosphere during the conversion process of making them, it can be an inefficient process. The new process allows for the wasted carbon dioxide to create more fuel. The hydrogen used is gleaned from water using non-fossil fuel energy (like solar energy).

It’s hopeful that while cars would still be generating CO2 emissions, the CO2 would be reabsorbed and used in the process once again, balancing the cycle of CO2. The process is a much cleaner version than the other coal options. In addition, it offers things electricity and hydrogen alone cannot provide.

The only drawback to this plan is storage. For large trains, planes and cars it would be difficult to store. The driving distances would be limited as well and the energy costs associated with this process could be very expensive.

Overall, there is hope in science finding a viable solution for the environment and for the needs and demands of driving Americans.
