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. Conventionally, plant operators can capture CO 2 by using special solvents that douse flue gas before it’s emitted from plant chimneys. Heldebrant, D.,

Transform Materials plasma process converts abundant natural gas into high-value hydrogen and acetylene

Green Car Congress

Transform Materials has developed a novel and sustainable microwave plasma reactor process to convert natural gas into high-value hydrogen and acetylene, thereby opening up a new pathway for green chemical manufacturing. Oxidation of methane also introduces impurities in the product stream.

Researchers use chemical looping process to produce hydrogen from hydrogen sulfide gas

Green Car Congress

Researchers at The Ohio State University have used a chemical looping process to produce hydrogen from hydrogen sulfide gas—commonly called “sewer gas”. Hydrogen sulfide is emitted from manure piles and sewer pipes and is a key byproduct of industrial activities including refining oil and gas, producing paper and mining.

ARPA-E awarding $30M to 12 hybrid solar projects; conversion and storage

Green Car Congress

Under the FOCUS program, projects will develop advanced solar converters that turn sunlight into electricity for immediate use, while also producing heat that can be stored at low cost for later use as well as innovative storage systems that accept both heat and electricity from variable solar sources.

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

The two main components—the electrochemical conversion hardware through which the fluids are flowed (which sets the peak power capacity) and the chemical storage tanks (which set the energy capacity)—may be independently sized. The design permits larger amounts of energy to be stored at lower cost than with traditional batteries.

EPFL team develops low-cost water splitting cell with solar-to-hydrogen efficiency of 12.3%

Green Car Congress

A team led by Dr. Michael Grätzel at EPFL (Ecole Polytechnique Fédérale de Lausanne) in Switzerland has developed a highly efficient and low-cost water-splitting cell combining an advanced perovskite tandem solar cell and a bi-functional Earth-abundant catalyst. Jingshan Luo, post-doctoral researcher, explains how. Credit: EPFL.

Bio-inspired molybdenum sulfide catalyst offers low-cost and efficient photo-electrochemical water splitting to produce hydrogen

Green Car Congress

The DTU researchers created a device to harvest the energy from part of the solar spectrum and used it to power the conversion of single hydrogen ions into hydrogen gas. When they exposed the pillars to light, hydrogen gas bubbled up—as quickly as if they’d used platinum.
