RENK supplies special gear units for compressors for production of green steel

Green Car Congress

Germany-based RENK Group, a manufacturer of mission-critical drive technologies, is supplying three high-speed special gear units via RENK-Maag GmbH , a group company, for compressors for the production of green steel to Siemens Energy Compressors GmbH as part of the “SALCOS” (Salzgitter Low CO2 Steelmaking) project of the Salzgitter AG steel group.

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.

MAHLE developing portfolio of solutions for fuel cell drives in commercial vehicles

Green Car Congress

Promising avenues include weight savings and extension of the cruising range in comparison with battery-powered solutions; fuel cell concepts may represent an attractive option for long-distance hauling, which requires heavy loads and large cruising ranges. As a result, the charge air coolers used must be resistant to ionized water.

SRI developing process for co-gasification of methane and coal to produce liquid transportation fuels; negligible water consumption, no CO2

Green Car Congress

Researchers from SRI International (SRI) are developing a methane-and-coal-to-liquids process that consumes negligible amounts of water and does not generate carbon dioxide. Lifecycle GHG comparison. In conventional CTL approaches, energy is supplied by burning a portion of the coal feed, which then produces carbon dioxide.

ARA Developing Catalytic Hydrothermal Process to Convert Plant Oils Into Non-Ester Biofuels (Biohydrocarbons)

Green Car Congress

Researchers at Applied Research Associates’ (ARA) Florida Research Laboratory are developing a catalytic hydrothermolysis (CH) process to convert triglycerides (e.g., To overcome these shortcomings, a novel technical approach based on high-temperature water chemistry, known as catalytic hydrothermolysis (CH), has been proposed.

Tunable high-yield catalytic approach converts pyrolysis oil to bio-hydrocarbon chemical feedstocks including fuel additives

Green Car Congress

However, the resulting bio-oils are typically high in oxygen, water, solids and acids. The zeolite catalyst then converts these hydrogenated products into light olefins and aromatic hydrocarbons in a yield as much as three times higher than that produced with the pure pyrolysis oil. earlier post.).

Purdue, EPFL team propose Hydricity concept for integrated co-production of H2 and electricity from solar thermal energy

Green Car Congress

The hydricity process entails integrating solar water power (SWP) cycle and solar thermal hydrogen production technologies and a turbine-based hydrogen power cycle with suitable improvements of each for compatibility and beneficial interaction. coproduced hydrogen has alternate usages in transportation/chemical/petrochemical industries.
