Power-to-X plants can generate renewable power and convert it into hydrogen or more advanced fuels for hard-to-abate sectors like the maritime industry. Using Bornholm Energy Island in Denmark as a study case, this investigates off-grid production e-bio-fuel marine fuels. It proposes pathway an analysis method of oil with comparison e-methanol. Production costs, optimal operations system sizing are derived using open-source techno-economic linear programming model. The source considered is...

The Viking gasification plant at the Technical University of Denmark was built to demonstrate a continuous combined heat and power operation two-stage gasifier fueled with wood chips. nominal input is 75 kW thermal. To validate plant, 9-day measurement campaign performed. verified stable energy balance resulted in an overall fuel gas efficiency 93% electricity 25%. Very low tar content producer observed: only 0.1 mg/Nm3 naphthalene could be measured raw gas. A engine on observed, very...
