Electrochemical deNOx

Removal of nitrogen oxides from all types of combustion of fossil/synthetic fuels is of outmost importance. Here a novel concept is suggested.

An alternative solution to remove NOx from Diesel engines is to use an all-solid-state electrochemical reactor, based on the solid oxide fuel cell technology, for the removal of the nitrogen oxides. Here, electrical energy is used directly to reduce the nitrogen oxides, instead of adding a reducing agent. However, electrochemical reduction of nitrogen oxides under net oxidizing is challenging. The main issue is to reduce the nitrogen oxides preferentially to the excess oxygen present in the exhaust gas, which leads to high power consumption. This can in part be solved by adding a storage compund, like an alkaline earth nitrate to the cathode.

Direct Carbon Fuel Cell

Biomass represents ca. 4% and ca. 26% of the primary energy consumption in the developed and developing countries, respectively. Electrochemical oxidation of biomass is a much more efficient and environmentally friendly route to directly convert the chemical energy stored in the biomass into electricity, compared to well-established conventional technologies.

The direct electrochemical oxidation offers a theoretical cell efficiency of 100%, which is far beyond the commonly achieved electrical efficiencies (20-25%) of conventional biomass-fired power plants. In addition to this, a fuel utilization of 100% is possible in the DCFC, which is higher than the 80% for hydrogen-fuelled fuel cells.

CO₂ Electrolysis

The transportation on the sea account for almost 1000 million tonnes of CO₂ per year. This is around 3% of the total global emissions. The international marine environment protection committee (MEPC) announced in 2018 that this should be decreased by 50%. This project will develop materials for conversion of CO₂ into useful chemicals/fuels (i.e. synthetic Diesel) using a low cost aqueous based electrolysis cell. The produced Diesel can be used to fuel e.g. container ships in a near future without fossil fuels being available. The main aim of this project is to significantly lower the cost of producing synthetic fuels.
