An electrolysis cell (solid oxide electrolysis cell, SOEC) developed jointly by DTU and Haldor Topsoe is used for electrolysis. In an SOEC, electricity from e.g. wind turbines is used to split water into its two constituents -- oxygen and hydrogen. The oxygen can be utilized in a thermal gasification process, where a biomass such as straw is broken down at high temperature. This creates synthesis gas -- a mixture of mainly hydrogen, carbon dioxide, and carbon monoxide. The gas mixture can be used in the production of methanol when the hydrogen produced by the electrolysis is added. Methanol can be used directly as fuel or catalytically upgraded to more familiar fuels used in ships and aircraft.
"In Synfuel, we have improved the two in technologies in several areas, and we've demonstrated that we can achieve higher utilization rates by combining the two technologies than when they run separately. We derive far more biofuel from the biomass resources and at the same time we can use surplus power from e.g. wind turbines to make fuel for heavy transport," says Professor Peter Vang Hendriksen, Synfuel project manager and Head of Section at DTU Energy.
The Synfuel project was supported by Innovation Fund Denmark. Haldor Topsoe, Orsted, Energinet.dk, MIT, Aalborg University, Chalmers University of Technology, INSA Lyon, TU Berlin, the Chinese Academy of Sciences, and others participated in the project. (Source: DTU, 10 July, 2020) Contact: DTU

The DTU Bioengineering scientists contend that Denmark can become a market leader if there is a high production of the particular enzymes.
According to the researchers,
200 tonnes of the enzyme can capture one million tpd of CO2.
A new technology needs to be developed to produce enzymes on a large scale, the DTU release notes.

DTI's wind turbine has a 3-meter-diameter rotor, comprising an aluminum hub and three CFRP composite blades, with a surrounding 3.7-meter-diameter GFRP duct -- shroud -- that increases airflow through the turbine blades. The duct was manufactu Empire Fiberglass Products Inc., and Vistex Composites fabricated the CFRP blades with partial grant funding from the National Science Foundation .
When Small Wind Certification Council certified and fully commercialized, the
DTI turbine is expected to sell for around $24,000, with two units generating sufficient to power the a average home.
