Industry - Industry transformations 6 Items
The shift from steel to carbon fiber in the transportation sector reduces steel production. With the rapid adoption of lightweight vehicles, RMI estimates that, in 2050, the auto industry will require one-fifth the steel used in 2010.
Projected reduction in U.S. steel demand will reduce the energy required by the industrial sector by 111 trillion BTU/y in 2050.
Energy to manufacture the required carbon fiber reinforced plastic (CFRP) used in the transportation sector is 45–120 TBTU/y by 2050. Future reductions in energy intensity and the use of recycled materials could further reduce this.
Carbon fiber production is more energy intensive than steel production (by mass). However, because revolutionary autos will require less body mass, there are significant opportunities for energy reduction in the auto manufacturing industry.
Transformations in the transportation sector will have the net effect of saving half of refining energy, cutting 2050 industrial energy use by 3.5 quads/y.
There are different types of biofuels as well as processes to create them. RMI analysis uses the National Renewable Energy Laboratory’s cellulosic ethanol process from corn stover as the basis for processing biofuels for the transportation sector.
