DOE researchers investigate economic and environmental impacts of converting wet waste to renewable diesel

Green Car Congress

Meanwhile, wet waste feedstocks, such as animal manure and fats, oils, and greases (FOG), represent another important category of resources that could be utilized to produce MCCI bioblendstocks due to its abundant availability. An open-access paper on their results is published in the journal ACS Sustainable Chemistry & Engineering.

EU Innovation Fund grants €108M to RWE’s waste-to-hydrogen project FUREC

Green Car Congress

RWE's FUREC project, which aims to produce circular and green hydrogen from non-recyclable municipal solid waste in Limburg, the Netherlands, received a €108-million grant from the EU’s Innovation Fund. For comparison: This is equivalent to the output of a 700-megawatt offshore wind farm with coupled electrolyzers. textiles, paper).

A*STAR team combines fungal culture and acid hydrolyses for cost-effective production of fermentable sugars from palm oil waste

Green Car Congress

Researchers from A*STAR in Singapore have developed a fungal culture for use in a cheap and efficient method to transform waste oil palm material into biofuels and environmentally friendly plastics. The palm oil waste contains cellulose and hemicellulose that can be broken down into sugars for use in fuel and plastic production.

Electra raises $85M to advance Low-Temperature Iron process; electrochemical refining at 60?C

Green Car Congress

By comparison, 69% of steel today is made at approximately 1,600 degrees Celsius (2,912 degrees Fahrenheit) using coal, emitting about two tons of carbon dioxide for every ton of steel produced. We also have a historic opportunity to decentralize the global iron and steel supply chain and re-shore manufacturing and mining jobs.

DOE to award up to $6.7M to projects to convert captured CO2 to useful products, including fuels

Green Car Congress

Research has shown that CO 2 can be converted to a variety of commodities, but because of the low energy state of CO 2 , the production costs would be prohibitive in many cases. Mineralization concepts utilizing CO 2 with industrial wastes. Mineralization concepts utilizing CO 2 with industrial wastes. coal, metals, etc.),

Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Because so much energy is lost turning steam back into water in the Rankine cycle, at most a third of the power in the steam can be converted into electricity. In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%. The recuperator improves the overall efficiency of the system.
