Alfa Laval introduces E-PowerPack ORC waste heat recovery system for ships

Green Car Congress

Alfa Laval is introducing the E-PowerPack waste heat recovery system for ships. Able to convert waste heat directly into electrical power, the E-PowerPack uses Organic Rankine Cycle (ORC) technology to reduce ship fuel consumption and CO 2 emissions. The basic principle of an ORC system can be thought of as the opposite of a heat pump.

KIT team produces synthetic natural gas from waste wood; used in natural gas vehicles

Green Car Congress

Researchers from the Karlsruhe Institute of Technology (KIT) have successfully produced renewable methane from a biomass-based synthesis gas mixture in their pilot plant for methanation using a new honeycomb catalyst. Biogas facilities produce renewable gas mainly by fermenting biological waste. Honeycomb catalyst.

Raven SR waste-to-hydrogen plant in California to be powered by INNIO Jenbacher’s Ready-for-H2 engines

Green Car Congress

At the site, landfill gas (LFG) will be the primary fuel to provide power for the non-combustion process that converts waste to hydrogen. The collaboration with Raven’s technology offers a strong renewable hydrogen alternative to electrolysis, using less electricity and no need for fresh water. Earlier post.).

Novel inexpensive cobalt-nickel electrode for efficient water and urea electrolysis; yolk-shell nanoparticles

Green Car Congress

Both half reactions of water electrolysis—hydrogen and oxygen evolution—are unfortunately slow and require a lot of power. To make the material, nanospheres made of cobalt–nickel–glycerate are subjected to combined hydrothermal sulfidation and gas-phase phosphorization. Zhang, S.L., and Lou, X.W.
