Onyeaka et al. (2024): Enhancing carbon neutrality: the role of biomass in CO2 uptake

Helen Onyeaka, Abarasi Hart, KeChrist Obileke IN: Advances in Sustainable Applications of Microalgae, https://doi.org/10.1016/B978-0-443-22127-9.00003-2

It is possible to achieve carbon neutrality through microalgae, forests, and crops since CO₂ uptake into their biomass is the primary hydrocarbon source. Since they uptake CO₂ through photosynthesis into biomass, as well as store it in the form of lipids, proteins, and carbohydrates during their growth phase, the biomass of lignocellulosic, microalgal, and agricultural crop residues can be used for chemicals and biofuels production. Their carbohydrates can be used as feedstock for bioethanol production, while their residual biomass can be used to produce bio-oil. As microalgae, forest trees, and crops grow, they capture almost the same amount of CO₂ released as biomass or fuel is burned, making their biomass a carbon-neutral energy source.
