Electrochemical synthesis of hydrogen peroxide from water, air and renewable electric energy

Project description

A sustainable route for hydrogen peroxide production

Striving to achieve a circular economy and climate neutrality, we must secure an affordable, sustainable and reliable supply of energy, raw materials and chemicals for Europe. Hydrogen peroxide (H2O2) is one of the most important inorganic chemicals produced worldwide for bleaching, paper recovery, sanitation and other purposes. However, its production still relies on the highly energy-intensive anthraquinone oxidation process. The EU-funded Power2Hype project enables a sustainable route for H2O2 production through a pioneering electrochemical process: cathodic oxygen reduction is paired with anodic water oxidation, enabling efficient H2O2 production in both half-cells. A downstream processing unit is developed and integrated with the electrolyser, yielding highly concentrated H2O2 solutions. In Power2Hype, the entire process chain is demonstrated at a technically relevant scale.

Objective

In line with the European Green Deal, the Processes4Planet partnership and the European initiative for more affordable, secure and sustainable energy (REPowerEU), the RIA proposal Power2Hype aims to establish a sustainable route for the hydrogen peroxide production. Based on air and water as feedstocks, and renewable energy as the sole energy source, the POWER2HYPE route addresses an economically viable and green alternative to the classical energy-demanding anthraquinone oxidation (AO) process. Hydrogen peroxide will be produced by paired electrolysis at both the cathode and anode using an innovative custom-made 200% electrolyser. Aiming the electrification and decentralization of the chemical industry, the POWER2HYPE concept proposes the TRL 6 demonstration of electrolytic hydrogen peroxide production at any given concentration (from 20 to 99 %) at the site where it is needed. With this flexibility of concentration range, hydrogen peroxide could be used from sanitation, bleaching to niche markets as propulsion fuels.
