Innovation

Industry Problem

Meloon GmbH is addressing the challenge of high industrial CO₂ emissions from energy-intensive processes that are difficult to decarbonize using traditional methods. Their technology aims to provide an efficient, low-cost, and easy-to-maintain carbon capture solution for these hard-to-abate sectors.

R&D Focus

Meloon GmbH is pioneering research and development in graphene-based membrane technology for industrial carbon capture, targeting a niche segment focused on mechanical, chemical-free CO₂ filtration. Their innovation addresses hard-to-abate sectors such as cement, steel, oil & gas, and petrochemicals, offering a simplified, cost-effective solution where traditional decarbonization methods are insufficient.

Innovative Solution

Meloon GmbH has developed a cutting-edge graphene-based membrane, a durable, ultra-thin “magic filter” that captures CO₂ directly from industrial emissions. Unlike conventional carbon capture systems that rely on heat and chemicals, Meloon’s solution uses a purely mechanical process, making it easy to maintain, energy-efficient, and cost-effective. This approach enables seamless integration into existing industrial plants and significantly reduces emissions without disrupting operations. By eliminating the need for complex infrastructure or chemical handling, Meloon offers a scalable, eco-friendly solution tailored to industries with high carbon footprints.

Solution Effectiveness

Meloon GmbH’s graphene-based carbon capture technology can reduce industrial CO₂ emissions by over 50%, making plants in sectors such as cement, waste-to-energy, and biogas nearly carbon-neutral. By capturing emissions directly and efficiently without heat or chemicals, their solution offers a scalable, cost-effective way to transform high-emission industries toward low-carbon and even negative-emission operations.
