Hydrogen as multivalent energy carrier - also for mobility?

Many countries around the world are turning towards climate friendly energy usage. One of the main options appreciated is seen in electricity won from renewables and then used in a direct way for stationary and mobile applications. Taking into account that there’s still a big lack for electric energy storage, hydrogen as an energy carrier more and more plays an important role. Producible via many different ways from almost any primary energy with different sizes of carbon footprints, it can be stored in large quantities, transported by pipelines, road or sea and can be used in a lot of applications. A selection of pathways for hydrogen as future energy carrier for mobility is presented and discussed.

Improving vapor compression system efficiency through advanced vapor compression technologies

The phase-out of ozone depleting and climate changing refrigerants as well as recent advances in compressor and other vapor compression component technologies, such as novel capacity control methods, use of smart sensors, materials and manufacturing practices, has rapidly increased the research efforts related to vapor compression systems for the HVAC&R industry. This presentation provides an overview of several research efforts related to novel compression concepts and unique cycle integration measures for refrigeration, air-conditioning and heat pumping applications with the goal to reduce irreversibilities and move system performance closer to Carnot efficiency. These research efforts include refrigerant injected compression with economization, near-isothermal compression with cylinder cooling and internal regeneration and rotor-cooled compression in twin screw compressors.  The latest state-of-the-art of each of these research efforts will be introduced and discussed.
