Wind turbines could offer a double whammy in the fight against climate change. Not only do they generate electricity
Wind turbines are an efficient way to generate clean energy, but they may also have a significant impact on the amount of carbon dioxide that is funneled into systems that remove the greenhouse gas from the atmosphere. Researchers say that their simulations show that wind turbines can drag dirty air from above a city or a smokestack into the turbines’ wakes, which increases the amount of CO2 that reaches machines that can remove it from the atmosphere. The researchers plan to describe their simulations and a wind tunnel test of a scaled-down system at a meeting
") When it comes to climate change, we can't just rely on reducing the amount of carbon dioxide that we put into the atmosphere. We also need to find ways to remove CO2 from the atmosphere that's already there. One potential solution is direct air capture systems.
But the large amounts of CO2 produced by factories, power plants and cities are often concentrated at heights that put it out of reach of machinery on the ground that can remove it. “We’re looking into the fluid dynamics benefits of utilizing the wake of the wind turbine to redirect higher concentrations” down to carbon capture systems, says mechanical engineer Clarice Nelson of Purdue University
Castillo and his colleagues are developing a computer model that could predict how much carbon dioxide an array of turbines could remove from the atmosphere. The model will also help assess the feasibility of using wind farms to meet carbon-neutrality goals. "The wind energy
Castillo's explanation of the benefits of wind turbines is both detailed and clever. By using the wind to take some of the dirty air in the city, the turbines are able to produce clean energy without using water. This is a major benefit, as it helps to conserve one of our most precious natural resources.
Wind turbines are a key player in the fight against climate change, but they could do even more to reduce carbon dioxide emissions. A new study suggests that by powering the capture of carbon dioxide with energy generated by the turbines, we could remove this greenhouse gas from the atmosphere at no additional cost. The study, published in the journal Joule, shows that the electricity generated by wind turbines can be used to power the direct air capture (
There are many factors that can impact the transport of CO2 by turbines in the real world. These include the interactions of the turbine wakes with water, plants, and the ground. Nicholas Hamilton, a mechanical engineer at the National Renewable Energy Laboratory in Golden, Colo., who was not involved in the new studies, says that he is interested to see how this
