Biofuels

Biofuels

The microbial conversion of organic matter into biofuels holds potential as a renewable energy source. Among biofuel sources, microalgae are recognized as a highly efficient and adaptable feedstock for biodiesel production, owing to their rapid biomass accumulation, elevated lipid productivity, and capacity to proliferate in diverse aquatic systems, including freshwater, marine, and wastewater habitats. Unlike terrestrial crops, microalgae do not compete for land and can achieve significantly...

Microbial Fuel Cells

Microbial Fuel Cells

Microbial fuel cells (MFCs) are bioelectrochemical devices that generate electricity by exploiting the metabolic processes of electrogenic bacteria. These systems provide a renewable energy source and serve as an innovative method for treating organic waste, such as wastewater.A typical MFC consists of two chambers: an anoxic (oxygen-free) compartment that houses the bacteria and an oxic (oxygen-rich) compartment that contains oxygen as the terminal electron acceptor. Many MFCs use proton...

Area of Science:

Sustainable Chemistry
Renewable Energy Technologies
Process Engineering

Background:

Biomass conversion to methanol is crucial for sustainable fuel production.
Integration with renewable energy and carbon capture enhances sustainability.
Assessing diverse feedstocks like lignocellulose and agri-food waste is vital.

Purpose of the Study:

To investigate an electrified biomass-to-methanol pathway.
To evaluate configurations including solar integration and methanation.
To determine techno-economic viability and minimum energy requirements.

Main Methods:

Process simulations in Aspen Plus for four system configurations.
Application of an advanced process optimization framework.
Assessment of lignocellulosic biomass (pine) and agri-food waste (spent coffee grounds).

Main Results:

Electrification improved carbon efficiency to 61.6% (lignocellulose) and 52.6% (agri-food waste).
Methanation and solar integration further increased efficiencies to 87.3% and 73.6% respectively.
Solar-assisted systems reduced methanol's minimum selling price and external utility dependence.

Conclusions:

Solar-assisted biomass-to-methanol systems are techno-economically viable.
Renewable electricity integration is feasible for methanol production.
This pathway offers a sustainable route for methanol synthesis in Spain.
