Meg energy storage

Does Meg have a bilayer structure?

Although MEG is being developed as a green renewable energy technology, there remains significant room for improvement in self-sustained power supply, generation duration, and energy density. In this study, we present a self-sustained, high-performance MEG device with a bilayer structure.

What does MEG do?

MEG uses steam and power for its production operations and provides excess electricity back to the Alberta grid. MEG's innovative technologies drive down steam to oil ratios (SOR) and decrease GHG emissions intensity.

What is the power density of Meg?

The assembled MEG demonstrates outstanding power generation performance, with a single unit providing an output voltage of 1.0 V and a power density of 26.5 μW cm −2 (53.0 μW cm −3), enabled by the synergistic effect of its double-gradient structure.

How long does Meg last?

Remarkably, encapsulating this MEG maintains its high performance output even after nearly three months. The short-circuit current of MEG reaches 1695 μA, with an energy density of 809.2 μW h cm −2, which is considerably higher than those reported in previous studies on MEG.

Why is the power density of Meg devices important?

The self-charging properties and sufficient power density of MEG devices are essential for their practical applications of powered devices. The power density of the PPC/Li-PMC MEG was evaluated by connecting the device to various external resistors.

Why is a reliable electric generation of Meg devices important?

Maintaining reliable electric generation is of great importance when the MEG device undergoes large deformation in practical applications. Herein, the voltage outputs of the PPC/Li-PMC MEG devices were monitored during compression cycles (Fig. S21).
