Startup licenses ORNL technology for converting organic waste to hydrogen

Green Car Congress

The technologies work as a system that converts organic waste into renewable hydrogen gas for use as a biofuel. The system combines biology and electrochemistry to degrade organic waste—such as plant biomass or food waste—to produce hydrogen. —Alex Lewis, CEO.

Sandia-led team demonstrates two efficient hybrid biochemical routes for lignin conversion to value-added chemicals

Green Car Congress

A Sandia National Laboratories-led team has demonstrated two new routes to lignin conversion that combine the advantages of earlier methods while minimizing their drawbacks. Conversely, harsh chemicals can deconstruct lignin in hours or even minutes. You want the organisms to make kilogram amounts in less than an hour, ideally.

KIST team develops rapid benchmarking platform for LOHCs

Green Car Congress

To overcome these limitations, research efforts to store hydrogen chemically in liquid carriers, such as liquid organic hydrogen carriers (LOHCs) or ammonia, have been conducted. Various organic compounds have been suggested for LOHCs. Credit: Korea Institute of Science and Technology(KIST). 2021.114124.

Japan team reports pathway to green ammonia: photocatalytic conversion of nitrogen with water

Green Car Congress

The solar-to-chemical energy conversion efficiency is 0.02%, which is the highest efficiency among the early reported photocatalytic systems. A number of inorganic or organic semiconductors have been tried for NH 3 production, but these suffer from low activity or stability. 7b06634.

New efficient biphasic catalytic process for conversion of biomass to dense jet-range fuels

Green Car Congress

In the proposed biTCP for cylcoalkane production, both hydrophilic and hydrophobic catalysts are added into two immiscible solven—an organic phase and an aqueous phase—creating a biphasic environment for a “cascade” of chemical reactions in both phases. —Yang et al. —Yang et al. —Yang et al.

Conversely, an increase in nitrate (NO 3 - ) from 1% to 71% resulted in a reduced RR, from 1.0100 (95%CI: 1.0067-1.0133) to 1.0037 (95%CI: 0.9998- 1.0077). and 5 million deaths worldwide in 2017. were found not to depend on the black carbon and organic carbon proportion and there was uncertainty about the role of sulfate.
