Transport & Mobility

Topic Background

For the longest time, most of the automobiles’ technological development for reducing carbon dioxide emissions has focused on the improvement in efficiency of internal-combustion engines. Since it is possible to keep internal-combustion engines highly efficient when engine load is constant, Toyota put a hybrid system that can absorb load fluctuations into practical use. This system, including the use of regenerated energy, can be called the ultimate low-carbon technology for internal-combustion engines.
Electric vehicles use batteries as an energy source, and so they do not emit carbon dioxide. If natural energy is stored at batteries, it is zero carbon mobility. However, automobiles require high output at the time of acceleration, and high energy density for running a long distance. High-performance batteries, including fuel cells, can be called the key technology for embodying next-generation automobiles.

Where we are heading

It is forecasted that the number of owned automobiles in the world will reach 2.1 billion in 2050 and over half of the increase from 2012 is in Asia. The figure below shows the prediction for each type of private cars. Energy Technology Perspectives 2012 of IEA estimated that the development and distribution of the next-generation automobile technology (EV and PHV) would reduce total CO2 emissions by about 1.7 billion tons in 2050. The key technologies are hybrid and electric vehicles.

  • August 29, 2016

PNNL and industry-partner LanzaTech are working together to convert alcohols derived from captured carbon monoxide(CO), a by-product in the production of steel, into synthetic paraffinic kerosene, a non-fossil-based jet fuel. The team achieved a milestone, producing 5 gallons of jet fuel in the lab, which allows them to scale up the production and move to the next stage of testing. http://energye...

According to SPM of IPCC AR-5 WG1(1) cumulative (anthropogenic) emissions of CO2 and global mean surface temperature response are approximately linearly related. It indicates that stabilization of the global surface temperature requires almost zero emission of CO2. Considering that more than 85% of primary energy mankind depend upon are fossil fuels, we mankind are required to make drastic efforts...
