SkyClean’s ‘carbon-negative’ fuel has taken another leap towards commercialization, having secured an initial $18 million for the construction of its first 20 MW facility in its home market of Denmark. Set to compete with hydrogen in the decarbonization of the much-debated aviation sector, this approach to fuel production could play a key role in achieving emission reductions and the production of a circular economy. Pioneered by wind-power legend Henrik Stiesdal, SkyClean’s pyrolysis process aims to combine agricultural waste with green hydrogen to produce jet fuel which is chemically identical to the A-1 fuel currently used by commercial airlines. With the absence of oxygen in the pyrolysis reaction, the only waste product from the process should be biochar, which can be…
