Hydrogen production and import thermal energy recovery and use: a study on water electrolysis waste heat and ammonia cracking cold utilisation

K. Bosch, Kamel Hooman

The aim of this study is to quantify and utilize waste heat from wind-farm-powered water electrolysers and ammonia cracking. The port of Rotterdam, as a case study, has been analyzed where the transport of 4.6 Mt hydrogen and water electrolysis, powered by …

The Effect of Packings on the Separation of Solvent and Condensate in Biomass Gasification Product Gas Scrubbers

R. Bardolf, K. Bosch, Reinhard Rauch, Hermann Hofbauer

By-products of biomass steam gasification are tar and water in the product gas. They can be removed by a cold biodiesel scrubber. Re-using the water phase for steam generation avoids wastewater, but a clean and oil­free condensate phase is required for correct …

Optimization of a 50 Mw Bubbling Fluidized Bed Biomass Combustion Furnace by Means of Computational Particle Fluid Dynamics

Stephan Kraft, Matthias Kuba, F. Kirnbauer, K. Bosch et autres

An efficient utilization of biomass fuels in CHP plants is often limited by the melting behavior of the biomass ash which causes unplanned shutdowns of the plants. If temperatures exceed the ash melting temperature deposits can affect the operation negatively: The deposits …

Performance of a Water Gas Shift Unit Processing Product Gas from Biomass Steam Gasification

Michael Kraussler, Matthias Binder, S. Fail, K. Bosch et autres

In this present paper, the performance of a commercial Fe/Cr based catalyst for the water gas shift reaction was investigated. The catalyst was applied in a water gas shift pilot plant which processed product gas from a commercial biomass steam gasification plant …

8.5 MWth CHP Plant in Oberwart, Austria - based on DFB Steam Gasification of Solid Biomass - Achieves Continuous Full Load Operation Through Stringent Optimization

J. Kotik, Reinhard Rauch, Hermann Hofbauer, K. Bosch et autres

In times of heavily fluctuating biomass prices for energy conversion/production, it is of utmost importance to secure and stabilize a continuously high load operation of decentralised CHP plants based on solid biomass such as wood chips from forestry. The 8.5 MWth CHP …

Designing Solid Oxide Fuel Cell Gas Turbine Hybrid Systems Using Exergy Analysis

K. Bosch, Nico Woudstra, K. V. van der Nat

In conventional gas turbine systems combustion results in high exergy losses (∼30%) of fuel exergy input. Replacing the combustor with a high temperature fuel cell, like the Solid Oxide Fuel Cell (SOFC), will significantly reduce these exergy losses. As the SOFC electrochemically …
