'Time points' are awarded according to the adequacy of the solution with the type of innovations sought by Time for the Planet®. They correspond to the analysis of several factors :

  • impact potential: impact average score > 4 => 0,5 point / if > 4,15 => 1 point.
  • global consistency: all average score of the 6 selection criteria > 2,5 => 1 point.
  • the favourite: % of assessments judge the innovation as a top one to act on a global scale against greenhouse gases > 20% => 1 point
  • the targeting: validation of Time for the Planet<span class="brand">®</span> scope of action higher than 90% => 0,5 point + innovation level of maturity is enough => 0,5 point
  • social acceptability: semantic analysis score of comments > 0 => 0,5 point/ if > 3500 => 1 point
50 assessments

Submitted to the Scientific Committee : After the evaluations made by our volunteer assessors, innovations with the strongest impact potential are submitted to the Scientific Committee. The managing directors are responsible for the choice.

EHM is a depollution solution with carbon-negative engines.

Submission date December 30, 2021 Founders Didier Arénal Development location Brest 29200 France, France

Detailed project

NB: this form is filled entirely by the ones submitting the innovation.

What is the issue addressed?

The innovation will make it possible to replace thermal engines with hydrogen engines that emit water vapor with a negative CO2 by capture.

How is the problem solved?

We invented an engine using hydrogen with a very efficient thermodynamic cycle.

What is the customer target?

Transporters, buses, private individuals, boats, and other vehicles equipped with combustion engines.

How is this solution different?

Our solution uses materials that are abundant on the planet. It allows the use of 100% green hydrogen, and it absorbs CO2.
