PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

Researchers at the Department of Energy’s Pacific Northwest National Laboratory have developed a new method to convert captured CO 2 into methane, the primary component of natural gas. Different methods for converting CO 2 into methane have long been known. A paper on the work is published in ChemSusChem. —Heldebrant et al.

UCLA team proposes non-photosynthetic biological conversion of CO2

Green Car Congress

Most of us naturally associate biological CO 2 conversion with photosynthesis in plants and algae. While engineering photosynthetic hosts to convert CO 2 into high-value products is sensible, dependence on sunlight limits its tractability and scalability. Their paper is published in the journal Joule. an and Park. 2020.08.007.

Researchers develop titanium and copper heterostructured photocatalyst for conversion of CO2 into CH4

Green Car Congress

Scientists at Daegu Gyeongbuk Institute of Science and Technology, Korea, have developed a novel heterostructured photocatalyst using titanium and copper, two abundant and relatively inexpensive metals, for the conversion of CO 2 into CH 4. Apart from its CO 2 conversion capabilities, the proposed photocatalyst has other benefits.

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

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. 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.

Montauk Renewables signs LOI with European Energy to provide CO2 for e-methanol production in Texas

Green Car Congress

The LOI immediately commits Montauk’s CO 2 from its Texas facilities to EE North America’s Texas Power-to-X project. Rendering of EE North America Power-to-X plant. EE North America intends to construct a Power-to-X facility in Texas that would take the biogenic CO 2 from Montauk’s locations and use it in the production of e-methanol.

New process uses localized surface plasmons for room-temperature conversion of CO2 to CO

Green Car Congress

Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have demonstrated a room-temperature method that could significantly reduce carbon dioxide levels in fossil-fuel power plant exhaust, one of the main sources of carbon emissions in the atmosphere.

WUSTL researchers demonstrate solar-panel-powered microbial electrosynthesis to produce n-butanol from light, CO2 and power

Green Car Congress

Here we have harnessed the power of microbes to convert carbon dioxide into value-added multi-carbon compounds in a usable biofuel. Microorganisms have evolved a bewildering array of techniques to obtain nutrients from their surrounding environments. We hope that it can be a steppingstone for future sustainable solar fuel production.
