Algal direct-air CO2 capture through interfacial enzyme immobilisation

由于固有的缓慢的传质动力学，直接从大气中捕获二氧化碳是具有挑战性的。这个项目旨在通过一种酶来克服这个问题，这种酶可以将空气中的二氧化碳快速溶解到水中，从而产生藻类。通过在空气-水界面处设计酶固定，该项目将激活和保护酶，延长酶的使用寿命并降低成本。通过了解界面固定介质中的传质和酶活性，可以开发漂浮酶筏，用于在广阔的区域部署，促进大气中的二氧化碳大规模转化为藻类衍生的燃料、饲料和化学品。

Capturing CO2 directly from the atmosphere is challenging due to inherently slow mass transfer kinetics. This project aims to overcome this using an enzyme that can rapidly solubilise CO2 from air into water, to produce algae. By engineering the enzyme immobilisation at the air-water interface, this project will activate and protect the enzymes, increasing their lifespan and reducing costs. By understanding mass transfer and enzyme activity in the interfacial immobilisation media, floating enzyme rafts can be developed for deployment over expansive areas, facilitating large-scale conversion of atmospheric CO2 into algae-derived fuels, feeds and chemicals.
