Harnessing the Power of Marine Biomass‐Derived Carbon for Electrochemical Energy Storage

Battery Energy, EarlyView.
Marine biomass is considerably a promising option for extracting carbon materials. Unlike other biomass, its chemical composition facilitated the power of EES devices. This review especially highlighted the efficacy of marine biomass‐derived carbon extracted from a variety of marine algae, fish waste, and skeletons of marine creatures on batteries and ...

Energy cover crops for biogas production increase soil organic carbon stocks: A modeling approach

GCB Bioenergy, Volume 15, Issue 2, Page 224-238, February 2023., 2023
The anaerobic digestion of cover crops for biogas production does not compete directly with food production and is promoted in various countries. Some questions arose regarding the effects of energy cover crops on soil organic carbon (SOC) stocks.

Extremum seeking via continuation techniques for optimizing biogas production in the chemostat [PDF]

arXiv, 2013
We consider the chemostat model with the substrate concentration as the single measurement. We propose a control strategy that drives the system at a steady state maximizing the gas production without the knowledge of the specific growth rate. Our approach separates the extremum seeking problem from the feedback control problem such that each of the ...

Replacing water and nutrients for ethanol production by ARTP derived biogas slurry tolerant Zymomonas mobilis strain

Biotechnology for Biofuels, 2019
Background Reducing fresh water consumption and nutrient addition will be an effective way to reduce the whole cost of bioethanol production. On the other hand, treatment of biogas slurry derived from anaerobic digestion (AD), in which a great amount of ...

Changing old habits: the case of feeding patterns in anaerobic digesters [PDF]

, 2016
A non-linear programming model was developed to maximize the economic profit from an anaerobic co-digester. The model consists of a combination of technical and economic equations, linked through the biogas production variable.
