There are numerous ways to remove CO2 from the air permanently without resorting to either burning fossil fuels or complicated sequestration methodologies.
The simplest is to promote the growth of seaborne organisms that turn CO2 into carbonate shells and then fall to the seabed to form - eventually - limestone and chalk layers (perhaps even future oil deposits). Any method that does this can use wave, tide, solar and wind power easily enough. My own idea, derived from the work of an Australian scientist, is to mass-produce free-floating wave-powered pumps to pump nutrient-rich cold seawater from the depths of the oceans, allowing oases of life to form around them and capture carbon on a growing and continuous scale.
