Performance analysis of ammonia and ammonia-water as working fluids for Ocean Thermal Energy Conversion power plants

At the Paris climate conference in December 2015, 195 countries adopted the first ever universal, legally binding global climate agreement. This combined with the depletion of fossil fuels drives the interest in renewable energy technologies. The thermal gradient in the ocean is a largely untapped source of renewable energy. It can be utilized...

The influence of the ammonia concentration on the performance of OTEC power cycles

The oceans cover over 70% of the earth’s surface and are therewith the largest source of renewable heat available on the planet. Ocean Thermal Energy Conversion (OTEC) is a process that exploits this low-grade oceanic heat. A heat engine is employed to generate electricity from the small temperature gradient that is available between the...

Polymer Heat Exchanger for Ocean Thermal Energy Conversion

Ocean Thermal Energy Conversion (OTEC) is a renewable energy technology which can operate as a base load source of energy in equatorial areas. By converting the thermal energy of the sun stored in the oceans into electricity, this technology provides a sustainable solution for tropical islands. One of the key factor to accelerate the roadmap...

Modelling the absorption of binary mixtures in plate heat exchangers

Ocean thermal energy conversion (OTEC) is currently developed as a clean and sustainable energy technology for offshore application in tropical areas. The technology shows promising possibilities in combination with the Kalina cycle, a thermodynamic cycle for the generation of energy from low temperature difference heat sources using a working...
