Transcript of Environmental Science Project
WAIT! Natural Gas is a fossil fuel...and the very process creates carbon monoxide. Doesn't that miss the point entirely?
Pretty much, yeah. So we need to come up with another way to produce H2... So what is the alternative? Well we could use electrolysis, but this method is net energy negative, so that is not viable.
In the late 90's it was discovered that C. reinhardtii algae produce hydrogen gas produce hydrogen when deprived of sulfur. It is believed that this process has the potential to create hydrogen gas while maintaining an overall net energy gain, thereby making hydrogen a viable fuel. Nate Hoxie + NET ENERGY = Energy consumed __________________ Energy produced The Big Picture Hydrogen Fuel Cells have great potential to be a staple energy source of the future, but it will not be the future of tomorrow, or even next year. An energy network based on hydrogen fuel cells will not be viable for at least a decade and will require an immense investment. However, the potential pay off of such an investment is extraordinary. Hydrogen fuel cells may very well ultimately be the form of renewable energy used in the next century and beyond. Positives
A long term solution for renewable energy
Produces no pollutants
Can be created just about anywhere on the globe, all countries could be energy independent Negatives
Currently has a low net energy.
Infrastructure is not there
Will take a lot of investment before any gain is seen
