The SpaceX chief recently shared a tweet claiming to donate “$100M towards a prize for best carbon-capture technology”. Later, Musk shared another tweet stating that details on the subject will be provided next week.

— Elon Musk (@elonmusk) January 21, 2021 Now, carbon-capture tech is not new in the market. Many machines based on carbon capture tech are currently in use at many points around the world where there is high carbon-emission such as near a manufacturing plant burning fossil fuels. As you can guess, these machines trap carbon dioxide, one of the primary greenhouse gases, before it goes into the environment. They recycle the gas and use it in a productive way. As a result, Musk further raised the question that can a Sabatier reactor be termed as a carbon-capture technology? For the unaware, the Sabatier reaction is an exothermic reaction that involves mixing hydrogen and carbon dioxide to produce methane and water, with nickel as a catalyst. So, if a Sabatier reactor is not a carbon-capture machine, then “maybe a good carbon capture machine can be used for a more efficient and powerful Sabatier reactor,” he further added. So, if there are any research team or organization working on the said subject, they can present their work and get ready to win the prize money to use it for further climate-development plans. Moreover, it seems like Musk is looking for better tech to develop fully renewable rocket energy. Although details are pretty scarce, as of now, it will be a bit more transparent when Musk shares the details about the initiative later this week.
