1. Supermarket refrigeration systems for demand response in smart grids
Abstract : With an increasing share of intermittent renewable energy sources in the electrical grid, the need for adapting the demand to the available supply of electricity becomes increasingly important. Within this thesis, the demand response capacity by supermarket refrigeration systems are investigated and methods for enabling it is developed. READ MORE

2. Coated Ferritic Stainless Steels as Interconnects in Solid Oxide Fuel Cells - Material Development and Electrical Properties
Abstract : Solid oxide fuel cells (SOFCs) are attracting increasing interest as devices with potentialuses in decentralized and clean electricity and heat production. Several challengeswith respect to materials have to be overcome to achieve efficiencies and life-spansthat are sufficient for long-term applications. READ MORE

5. Mechanism of the passive NOx adsorption process on zeolite-supported Pd in controlling cold-start emissions
Abstract : Passive NOx adsorbers (PNA) have been used for preventing NOx emissions being released during a cold start. This method involves trapping NOx on an adsorbent at low temperatures and releasing them later, when the exhaust temperature exceeds 200℃. READ MORE
