Lab on a chip for a low-carbon future

Abstract

We describe how lab-on-a-chip systems can help address challenges in: (I) carbon sequestration, (II) hydrogen storage, (III) geothermal energy extraction, (IV) bioenergy, (V) recovering critical materials, and (VI) water filtration and remediation.

Review on Multiscale CO2 Mineralization and Geological Storage: Mechanisms, Characterization, Modeling, Applications and Perspectives

“…Reactive transport processes for the storage of CO 2 mineralization are controlled by the multiphase flow dynamics of porous media. The microfluidic modeling approach plays a key role in advancing the understanding of pore-scale multiphase flow by enabling the precise control of geometry and surface properties and allowing direct visualization. − …”

Visualization and Quantification of Mobility Reduction in Porous Media Flow Associated with Pore Blocking by Emulsion Drops

“…Recent improvements in microfabrication methods for microfluidic devices have led to a growth in the use of porescale flow visualization to better understand complex multiphase flow in porous media. 6,11,14,18 Microfluidic models of porous media have been used to study polymer flow, 8,19 twophase flow with different wettability conditions 2,34 In this present work, we extend previous pore-scale visualization studies of emulsion flow by using a porous media microfluidic model that has pore throats of different widths and a polydispersed emulsion with drop size distribution within the range of the pore throat sizes. These conditions are closer to the field application of emulsion injection as an EOR method.…”

Differential microthermometry enables high-throughput calorimetry

“…Thermal fluids are central to the current energy system 1,2 and to realizing the potential of industrial electrification, highpower computing, renewable energy generation, and energy storage. 3,4 The demands of these applications are distinct from those of the internal combustion engines that have driven the development of coolants for over a century. 5 Addressing the emerging applications will require accelerated discovery of bespoke thermal fluid formulations.…”
