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.

Raven SR & Hyzon Motors to build up to 100 waste-to-hydrogen hubs

Green Car Congress

At the hubs, which can be built at or near landfills, Raven SR will convert mixed and multiple organic wastes, including municipal solid waste, greenwaste, food waste, medical, paper, etc. This permits the control of the rotary reformer when there is water content or chemical makeup variation in the feedstock, such as in MSW.

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. However, their large-scale use is impeded by high costs, limited abundance, and low stability. Sources of urea could include waste streams from industrial syntheses as well as sanitary sewage.

Pitt engineers using membrane distillation to recycle water used in fracking and drilling

Green Car Congress

Engineers at the University of Pittsburgh Swanson School of Engineering are using membrane distillation technology to enable drillers to filter and reuse the produced water in the oil and gas industry, in agriculture, and other beneficial uses. The method is already being tested in Texas, North Dakota, and most recently in New Stanton, Pa.
