Planes, trains, and automobiles. Transportation accounted for 27% of global GHG emissions in 2013.
Incorporating large amounts of magnesium in vehicle bodies could significantly reduce the global GHG emissions from the transportation sector. A 10% reduction in vehicle weight can result in 6-8% improved fuel economy while maintaining structural integrity and safety.
So what’s holding us back?
Magnesium production is expensive! Magnesium production needs to be cheap and reliable before we will see any large scale changes take place in the transportation industry. Big Blue Technologies hopes to provide the technology that can catalyze this change.
Additionally, current production methods for magnesium are dirty, resulting in high energy requirements and carbon emissions. Replacing steel parts for magnesium parts in vehicles may result in higher fuel efficiency, but if those magnesium parts were produced using a polluting process, then there is no net energy benefit.
