Electrochemical Peroxide Synthesis

Secure, Sustainable, Self-sufficient Island Communities

The Problem

Despite the ubiquitous applications for hydrogen peroxide (H2O2) in healthcare as a disinfectant, in water treatment and environmental remediation, and as a key oxidant in the PICO process to remediate plastic waste, H2O2 production remains expensive and only suitable for large economies of scale. The low stability of H2O2 combined with the expense of transporting large, dilute volumes has handicapped much needed distributed, decentralized electrochemical peroxide synthesis.

The Opportunity

Decades of progress in water electrolysis, or the conversion of H2O into hydrogen gas (H2) and oxygen gas (O2) have yielded new electrodes, catalysts, and reactor designs at both small and large scales for the production of H2O2 from H2O. Innovations in energy efficiency and capital costs would enable smaller peroxide generators utilizing renewable energy to produce H2O2 directly onsite where it is needed. Eliminating the need to ship and transport this unstable material over long distances allows us to more easily produce dilute, non-hazardous concentrations at lower cost.

What we're doing about it

We're developing a low-cost, distributed electrochemical H2O2 generator. Our design is built from widely available, off-the-shelf components in an innovative air-lift reactor design. A key feature of this technology is the utilization of low-cost, easily replaced/refurbished carbon electrocatalysts that eliminate the need for the traditional costly, unstable, and toxic metal-based electrocatalysts.
