A profound understanding of the fuel conversion on a grate boiler is crucial for an optimised boiler operation with a minimised pollutant emission. This work presents gas measurements and numeric simulations of a 150 kW moving grate boiler. The fuel bed model considers drying, pyrolysis and gasification. In the experiments, temperature…

Hydrothermal gasification (HTG) is a promising technology that allows the recovery of nutrients from wet biomass with simultaneous production of an energy-rich gas. In this work, wastewater effluent (leachate) obtained from a composter sanitary system operating without external connection to sewer pipes was used as a feedstock for HTG process. The leachate effluent was characterized…

Researchers at EPFL found a way to produce the core component of a Solid Oxide Fuel Cell cheaper and more efficient than existing solutions. Following the start-up textbook they spun off a company to supply exactly this component to the Fuel Cell manufacturers – as lean as possible. But the Fuel Cell manufacturers collapsed…
