The Seeker is looking for technology or methods to unload high moisture coal from railway carriage without coal masses sticking on the coal receiving bins and implementation of coal transportation along the existing equipment with good flow properties (normal flowability) in all seasons.

This Theoretical Challenge requires only a written proposal.


Coal is an important energy source and plays a vital role in power production. When it is extracted from mines, it always contains a certain level of moisture, and thus high moisture content has become one of its characteristics. This characteristic is considered undesirable since it transforms coal after strong wetting into clays (also called mudstones) and forms coal masses. Due to the material’s cohesive strength, the coal masses stick on the sidewalls of the coal-receiving and transportation equipment and result in arches (called bridging) once the coal is discharged. Cleaning, scraping and removing arches creates a considerable amount of downtime, inefficiency and excessive labor throughout the entire milling system.

In order to eliminate the processes for cleaning and dislodging coal buildups, the Seeker requires effective ways to prevent coal masses on the coal receiving bins and implementation of coal transportation along the existing equipment in all seasons.  

This is a Theoretical Challenge that requires only a written proposal to be submitted. The Challenge award will be contingent upon theoretical evaluation of the proposal by the Seeker.

To receive an award, the Solvers will not have to transfer their exclusive IP rights to the Seeker. Instead, Solvers will grant to the Seeker a non-exclusive license to practice their solutions. 

Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on October 13, 2019.

Late submissions will not be considered.

What is InnoCentive?
InnoCentive is the global innovation marketplace where creative minds solve some of the world's most important problems for cash awards up to $1 million. Commercial, governmental and humanitarian organizations engage with InnoCentive to solve problems that can impact humankind in areas ranging from the environment to medical advancements.

What is a Theoretical-Licensing Challenge?

An InnoCentive Theoretical Challenge builds upon an idea but is not yet a proof of concept. A solution to a Theoretical Challenge will solidify the Solver's concept with detailed descriptions, specifications and requirements necessary to bringing a good idea closer to becoming an actual product or service.

This Challenge is a Theoretical-Licensing Challenge, meaning that the Seeker is requesting non-exclusive rights to use the winning solution. By contrast, Theoretical-IP Transfer means that Solvers must relinquish all rights to the Intellectual Property (IP) for which they are awarded. For these forms of a Theoretical Challenge, Solvers that do not win retain the rights to their solution after the evaluation period is complete. The Seeker retains no rights to any IP not awarded.
