Problem
Conventional bipolar membranes (BPMs) used in various electrochemical processes, such as water treatment, lithium processing, and CO₂ capture, are limited by low current densities, typically operating below 0.1 A/cm². This limitation results in higher energy consumption and increased capital expenditure due to the need for larger electrodialysis stacks.
Solution
Bardo Climate provides high-performance bipolar membranes featuring a novel 3D junction design that enables significantly higher current densities, up to 1 A/cm², without delamination or increased voltage. These membranes facilitate more efficient electrodialysis, reducing energy consumption by over 30% and total capital expenditure by 50% compared to traditional 2D junction BPMs. Bardo's BPMs can be applied to water treatment for desalination and selective ion separation, lithium processing for extraction and refining, acid and base production via electrodialysis, CO₂ capture through electrodialytic methods, long-duration energy storage in acid-base redox flow batteries, and hydrogen electrolysis.
Target Audience
Bardo Climate's primary customers include companies in the water treatment, lithium processing, chemical production, carbon capture, energy storage, and hydrogen production industries seeking to improve the efficiency and reduce the costs of their electrochemical processes.
