Kobe team develops method for highly efficient hydrogen production using sunlight, water and hematite

Green Car Congress

A research group led by Associate Professor Takashi Tachikawa of Kobe University’s Molecular Photoscience Research Center has developed a strategy that greatly increases the amount of hydrogen produced from sunlight and water using hematite (??Fe Mesocrystal photoanode formation and photochemical water splitting characteristics.

STEAG and thyssenkrupp planning joint green hydrogen project

Green Car Congress

In the next few years, the company expects the conversion of one blast furnace to result in an annual demand of around 20,000 tonnes of green hydrogen. This demand will increase to some 720,000 tonnes per year by 2050 as a result of the gradual conversion of the plants and equipment.

New plasma synthesis process for one-step conversion of CO2 and methane into higher value fuel and chemicals

Green Car Congress

Instead of using H 2 , direct conversion of CO 2 with CH 4 (dry reforming of methane, DRM) to liquid fuels and chemicals (e.g. natural gas, shale gas, biogas and flared gas). The DBD reactor was connected to an AC high voltage power supply with a maximum peak voltage of 30 kV and a variable frequency of 7-12 kHz.

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

Green Car Congress

Supercritical carbon dioxide is a non-toxic, stable material that is under so much pressure it acts like both a liquid and a gas. This carbon dioxide, which stays within the system and is not released as a greenhouse gas, can get much hotter than steam—1,290 degrees Fahrenheit or 700 Celsius.

USDA provides $91M loan guarantee to Cool Planet for biogasoline blendstock plant; biomass pyrolysis and catalytic conversion

Green Car Congress

Gas chromatography comparison of Conoco fuel and a Conoco-CoolPlanet blend. Cool Planet has devised a biomass-to-liquids thermochemical conversion process that simultaneously produces liquid fuels and sequesterable biochar useful as a soil amendment. The output of these processing stations is connected to an array of catalysts.

New highly efficient catalyst for photoelectrochemical CO2 reduction toward methane

Green Car Congress

The calculations of reaction energetics suggest that Cu and Fe in the binary system can work in synergy to significantly deform the linear configuration of CO 2 and reduce the high energy barrier by stabilizing the reaction intermediates, thus spontaneously favoring CO 2 activation and conversion for methane synthesis.

HYBRIT produces hydrogen-reduced sponge iron on pilot scale

Green Car Congress

The technological breakthrough within the HYBRIT ( earlier post ) initiative cuts about 90% of the emissions in connection with steel production and is a decisive step on the road to fossil-free steel. With SSAB’s conversion, we will reduce carbon dioxide emissions by 10 percent in Sweden and 7 percent in Finland.
