Great!
I am very proud to announce a paper in Nature, in which Bert Weckhuysen and myself examine the viability of a completely fossil-free future refinery. The paper appears on the cover of Nature of May 9, 2024, and is accompanied by an editorial. Present refineries convert crude oil to transportation fuels and various chemicals as well as raw materials, such as the starting materials (monomers) for polymers, such as coatings and plastics. Both the processing of the fossil fuels as well in their eventual burning in internal combustion engines leads to CO2-emissions. We examine a refinery concept in which the transportation fuels of the future are made from CO2, whereas the chemicals and monomers are made from biomass and plastic waste. We conclude such a refinery is technically feasible, but will require tremendous amounts of green energy to produce the hydrogen required in the conversion processes. Depending on the efficiency and overall integration of all the conversion processes for biomass and plastic waste, the refinery could become carbon-neutral. A lot of science and technology will be required to build the new refineries, and significant investments will need to be made consistently over the next 25+ years. Building the wind turbines and solar panels to generate the required electricity will place a heavy burden on critical raw materials. In order to support these transitions, we will need to educate a new generation of chemists, who can combine deep knowledge of chemistry and technology with a skill set that will allow them to operate in a trans-disciplinary environment.
