Enel believes that innovation is indivisible from sustainability and research of most effective and sustainable technologies requires a constant and focused effort. Enel is seeking a high performance technology for the disinfection of cooling water in existing evaporative towers adopting new approaches and overcoming the conventional processes.

This Theoretical Challenge requires only a written proposal.                          


Cooling towers are primarily used in industrial settings to reduce the temperature of circulating water. By exposing the water to air, evaporation occurs, thereby dissipating the heat into the atmosphere. The moist environment and the longer retention time of water encourage growth of microorganisms on the surfaces of the tower and the condenser and these films not only diminish heat transfer efficiency, but also accelerate corrosion rates. Therefore, Enel is seeking innovative solutions that allow the disinfection of cooling water in evaporative towers with new approaches overcoming the conventional processes adopted by industries. Submissions will include a technical description of the technology and evidence of its ability to disinfect and prevent biofouling.

This Challenge provides contribution to the following SDGs:

•     SDG 6, 12

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

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

Submissions to this Challenge must be received by 11:59 PM (Central European Time) on January 28, 2019. 

Late submissions will not be considered.

After the Challenge deadline, the Seeker will complete the review process and make a decision with regards to the Winning Solution(s). All Solvers that submit a proposal will be notified on the status of their submissions.


Enel is a multinational energy company and one of the world’s leading integrated electricity and gas operators. Enel works in 34 countries across 5 continents, generating energy with a net installed capacity of more than 86 GW, selling gas and distributing electricity across a network spanning approximately 2.2 million km.

With almost 71 million end users around the world, Enel has the biggest customer base among its European competitors, and it is one of Europe’s leading energy companies by installed capacity and reported EBITDA. The Enel Group is made up of nearly 70,000 people from around the world whose brilliant work is based on our values of Responsibility, Innovation, Trust and Proactivity.

Enel is dedicated to creating innovative solutions that meet society’s changing needs. Through its crowdsourcing platform, the company connects people and ideas from across the world, encouraging anyone to propose sustainable innovation projects and solutions that help develop local communities.

Enel is also committed to helping to achieve four of the 17 UN Sustainable Development Goals (SDGs):

7 – Access to affordable and clean energy

4 – Support for quality education

8 – Contributing to socio-economic development in the communities in which Enel operates

13 – The fight against climate change

Enel Produzione S.p.A – Innovation of Global Thermal Generation is part of Enel Group. Innovation, within the Global Thermal Generation Business lines has the following responsibilities:

– To define power generation technologies of interest as well as innovation project portfolio;

– To manage Innovation projects aimed at improving operational performances of existing power plants

Innovation develops activities and projects aiming at developing advanced technological solutions for increasing power plants environmental and technical performances, flexibility and reliability and at identifying advanced integrated technological systems for power plants monitoring/diagnostic and safety management.

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.
