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.

Eaton introduces DC-DC converters for 48V commercial vehicle architectures

Green Car Congress

We’re delighted to deliver power-conversion technology designed specifically to meet the demands of commercial vehicle electrical systems. The bi-directional unit then further reduces the power to 12 volts for use in low-voltage systems and charges a 12-volt battery that stores power in case of a fault in the main power supply.

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. Moreover, it is a cheap carbon source which can increase the atom utilization of CO 2 hydrogenation due to the stoichiometric ratio of C and O atoms, as well as reducing the formation of water. … Wang et al.

Swiss team develops effective and low-cost solar water-splitting device; 14.2% solar-to-hydrogen efficiency

Green Car Congress

As the V OC of the presented c-Si cells is only ∼600 mV, four cells need to be connected in series to achieve stable water splitting performance. We demonstrate in this study that, thanks to their high V OC , three series-connected SHJ cells can already stably drive the water splitting reaction at unprecedented SHE.

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%. It took us a long time to get the data needed to let us connect to the grid.

NREL researchers capture excess photon energy to produce solar fuels; higher efficiency water-splitting for H2

Green Car Congress

The advancement could significantly boost the production of hydrogen from sunlight by using the cell to split water at a higher efficiency and lower cost than current photoelectrochemical approaches. A salt bridge connects the two compartments and transports H + and Na +. The research is outlined in a paper in Nature Energy.

Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires. Earlier post.). simulated sunlight. constructing a simple, stand-alone device composed of.
