虽然丰田一直对完全过渡到全电动阵容持谨慎态度,但一些分析师支持这一立场,但该公司正在积极寻求替代绿色技术。正在开发的一个概念不仅旨在提高其新车的环保性,而且还旨在解决过时的内燃机对环境的影响。
丰田正在开发可以集成到其车辆前部的过滤器,以从大气中吸收二氧化碳。该公司目前正在其氢燃烧GR Corolla赛车上试验这一概念。据丰田称,初步测试表明,这项创新可能会使其汽车实现负碳,而不仅仅是碳中和。
该技术很聪明,因为它不需要任何额外的电源即可工作。汽车前部的圆形过滤器捕获二氧化碳,然后利用发动机的废热将其溶解成可处理的液体。这意味着这项技术也可以用于普通内燃机,而不仅仅是那些使用氢气的内燃机。

在丰田的愿景中,这将创造一种在驾驶过程中真正净化空气的车辆。不幸的是,这项技术还有很长的路要走。在测试中,过滤器在20圈跑步(57英里/91公里)中仅捕获了20克二氧化碳。这总比没有好,但使用化石燃料的发动机平均每加仑消耗 8,887 克二氧化碳。
更大的过滤器可以吸收更多的二氧化碳,但它们可能很难包装在乘用车中。然而,将它们部署在日野卡车等商用车上,可以促进这项技术的进步。
更成问题的是,关于如何安全地处理含有二氧化碳的液体仍然存在争议。此外,该技术目前非常不方便。在用于测试它的 GR Corolla Toyota 中,每次进站都需要手动更换过滤器,这导致了有关浪费等问题。
然而,如果丰田能够成功开发出在驾驶员驾驶车辆时被动地从空气中吸收二氧化碳的技术,它可能会成为一项非常有价值的创新。然而,它的发展正值该公司试图恢复其绿色形象之际,此前有报道称它为否认美国政客的气候变化运动做出了贡献。https://www.carscoops.com/wp-content/uploads/2024/02/2023-Toyota-GR-Corolla-Hydrogen-Carbon-Capture-Tech-4-1024x683.jpg

Toyota Tests Tech That Sucks CO2 From The Air On GR Corolla
A filter could suck up CO2 in the air as cars drive, but right now the technology is slow and invonvenient
4 hours ago
While Toyota has been cautious about fully transitioning to an all-electric lineup, a stance supported by some analysts, the company is actively pursuing alternative green technologies. One concept in development not only aims to enhance the eco-friendliness of its new vehicles but also tackle the environmental aftermath of outdated internal combustion engines.
Toyota is developing filters that could be integrated into the front of its vehicles to suck carbon dioxide from the atmosphere. The company is currently experimenting with this concept on its hydrogen combustion GR Corolla racecar. According to Toyota, initial tests suggest that this innovation could potentially render its cars carbon negative rather than merely carbon neutral.
The technology is clever in that it doesn’t require any additional power to work. Circular filters at the front of the car capture carbon dioxide, then waste heat from the engine is used to dissolve it into a liquid that can be disposed of. That means that this technology could also work in regular combustion engines, not just those who run on hydrogen.

In Toyota’s vision, that would create a vehicle that actually cleans the air as it is being driven. Unfortunately, the technology is still a long way off. In its test, the filters only captured 20 grams of carbon dioxide in 20 laps of running (57 miles/91 km). That’s better than nothing, but engines running on fossil fuels emit 8,887 grams of carbon dioxide per gallon they consume, on average.
Bigger filters could suck up more carbon dioxide, but they would likely be difficult to package in passenger vehicles. However, deploying them in commercial vehicles, such as Hino trucks, could facilitate the advancement of this technology.
What’s more problematic is that there is still debate about how to safely deal with the liquid that contains the CO2. Furthermore, the technology is currently pretty inconvenient. In the GR Corolla Toyota used to test it, the filters needed to be changed manually during every pit stop, leading to questions about waste, among other things.
Yet, if Toyota can successfully develop the technology to passively suck CO2 from the air while drivers operate their vehicles, it could become a highly valuable innovation. However, its development comes as the company is attempting to rehabilitate its green image, following reports that it contributed to the campaigns of climate change denying politicians in the U.S.
