The Case for Nuclear Cargo Ships

Cars That Think

Nearly all of the world’s ship fleet still runs on diesel fuel, with about a quarter of new ships on order being built to run on somewhat lower-carbon alternatives like liquefied natural gas, methanol, or hybrid propulsion. Another plus for nuclear-propelled ships is easy access to an endless supply of cooling water.

Researchers propose CO2 recycling to improve Fischer-Tropsch GTL efficiency and reduce total CO2 emissions

Green Car Congress

Researchers in South Korea are suggesting two new carbon-dioxide-utilized Gas-to-Liquids processes (CUGP) to increase the overall efficiency of conventional Fischer-Tropsch GTL. T synthesis catalysts are beneficial for CO 2 conversion. Overview of the CUGP processes. Credit: ACS, Zhang et al. Click to enlarge.

S. Korean researchers develop new catalytic pathway for direct conversion of CO2 to liquid hydrocarbon fuels

Green Car Congress

A team led by Professor Jae Sung Lee at Ulsan National Institute of Science and Technology (UNIST), with colleagues at Pohang University of Science and Technology (POSTECH), have developed a new pathway for the direct conversion of CO 2 to liquid transportation fuels by reaction with renewable hydrogen produced by solar water splitting.

Naysayer Alert – the hydrogen red herring

My Electric Car

The only by products are water and a fair degree of heat, the latter indicating a degree of inefficiency and wasted energy. Second, while hydrogen can be otherwise produced through the electrolysis of water, this process requires huge amounts of clean and fresh water – a vital and highly valuable commodity of life that can’t be wasted.
