PNNL biocrude-to-diesel demo passes 2,000-hour catalyst stability milestone

Green Car Congress

The biocrude oil came from many different sources, including wastewater sludge from Detroit, and food waste collected from prison and an army base. The research showed that essentially any biocrude, regardless of wet-waste sources, could be used in the process and the catalyst remained robust during the entire run.

Panasonic develops highly efficient artificial photosynthesis system with gallium nitride semiconductor for conversion of CO2 to formic acid

Green Car Congress

This will make it possible to realize a simple and compact system for capturing and converting wasted carbon dioxide from incinerators and electric generation plants, according to Panasonic. The conversion efficiency of solar energy to chemical energy was 0.03-0.04%. Applied Physics Letters , Volume 100, Issue 24, id.

LanzaTech collaborating with Swayana to convert waste gases from ferroalloy production to ethanol

Green Car Congress

South African engineering company Swayana has signed a Memorandum of Understanding (MoU) with LanzaTech to collaborate on developing projects for the production of ethanol and higher value products from waste gases in the ferroalloy and titania smelting sectors. during steel manufacturing.

MISC, Samsung Heavy, Lloyd’s Register and MAN partner to develop ammonia-fueled tanker

Green Car Congress

Ammonia is just one of the pathways towards zero-carbon emitting vessels. Ammonia is a carbon-free fuel and can be produced from renewable electricity. The energy conversion rate of this system is higher than that of biomaterial-based systems, but the production pathway cannot tap into potential energy sources such as waste biomass.

Study suggests that decarbonizing US transport sector by converting waste CO2 to fuels would require economical air-capture of CO2

Green Car Congress

Kreutz used two examples of CCTF systems in his analysis: biodiesel from microalgae and Sandia National Laboratory’s S2P process (an effort to utilize concentrated solar energy to convert waste CO 2 into synthetic fuels, earlier post ). 90%) or to “repower” using lower carbon feedstocks or generation technologies (e.g.

LanzaTech exploring lipids production as part of its CO2 to acetic acid plans; pathways to renewable fuels

Green Car Congress

In a presentation at the 1 st Conference on CO 2 as Feedstock , held last week in Essen, Germany, LanzaTech CSO Dr. Sean Simpson described the company’s progress on developing a CO 2 pathway. Part of the challenge is locating sufficient quantities of hydrogen to enable large scale use of the CO 2 in waste gases. Earlier post.).

Taiwan team engineers E. coli to produce n-butanol from glycerol

Green Car Congress

The conversion yield and the productivity reached 87% of the theoretical yield and 0.18 The situation is even worsened by the additional cost for disposal of glycerol waste. Used as a feedstock, glycerol is attractive because it has the highly reduced carbon atoms and enables generation of more reducing equivalents than glucose.
