Elon Musk is donating $100M to find the best carbon capture technology
Elon Musk said Thursday via a tweet that he will donate $100 million toward a prize for the best carbon capture technology.
Musk, who recently surpassed Amazon’s Jeff Bezos to become the world’s richest person, didn’t provide any more details except to add in an accompanying tweet the “details will come next week.” It’s unclear if this is a contribution to another organization that is putting together a prize such as the Xprize or if this is another Musk-led production.
The broad definition of carbon capture and storage is as the name implies. Waste carbon dioxide emitted at a refinery or factory is captured at the source and then stored in an aim to remove the potential harmful byproduct from the environment and mitigate climate change. It’s not a new pursuit and numerous companies have popped up over the past two decades with varying means of achieving the same end goal.
The high upfront cost to carbon capture and storage or sequestration (CCS) has been a primary hurdle for the technology. However, there are companies that have found promise in carbon capture and utilization — a cousin to CCS in which the collected emissions are then converted to other more valuable uses.
For instance, LanzaTech has developed technology that captures waste gas emissions and uses bacteria to turn it into useable ethanol fuel. A bioreactor is used to convert into liquids captured and compressed waste emissions from a steel mill or factory or any other emissions-producing enterprises. The core technology of LanzaTech is a bacteria that likes to eat these dirty gas streams. As the bacteria eats the emissions it essentially ferments them and emits ethanol. The ethanol can then be turned into various products. LanzaTech is spinning off businesses that specialize in a different product. The company has created a spin-off called LanzaJet and is working on other possible products such as converting ethanol to ethylene, which is used to make polyethylene for bottles and PEP for fibers used to make clothes.
Other examples include Climeworks and Carbon Engineering.
Climeworks, a Swiss startup, specializes in direct air capture. Direct air capture uses filters to grab carbon dioxide from the air. The emissions are then either stored or sold for other uses, including fertilizer or even to add bubbles found in soda-type drinks. Carbon Engineering is a Canadian company that removes carbon dioxide from the atmosphere and processes it for use in enhanced oil recovery or even to create new synthetic fuels.
