Haffner Energy: DNV Confirms Successful H6 Trial, Mobility-Grade Hydrogen in Sight
The final report from independent body DNV, received by Haffner Energy on October 14, 2026, formalizes the conclusions of the first qualification sequence of the H6 generation dedicated to syngas production. The company specified that a second sequence, devoted to mobility-grade hydrogen, is scheduled for the current quarter.
A DNV Report Confirming Stable Operation of the H6
On August 6, 2026, Haffner Energy announced that it had achieved the main qualification milestone for its new H6 generation, under the supervision of an independent international body. The latter, DNV (Det Norske Veritas), submitted its final report on this first sequence on October 14. According to the company, the document is based on the analysis of hundreds of operational data collected during the tests. Among its conclusions, DNV notably states, according to the translation provided by the company: "DNV confirms that the test was successful", "Stable operation was achieved" and "The technological concept is functional". In its communication, Philippe Haffner, Chief Executive Officer, recalled that this qualification specifically concerns the H6 generation, and not the principle of the thermolysis technology itself. According to him, this principle has already been tested for several thousand hours of operation with generations H3 and H4.
Mobility-Grade Hydrogen Planned This Quarter
Syngas, primarily composed of hydrogen and carbon monoxide, is presented by the company as the precursor from which most of the renewable productions it targets can be obtained. Haffner Energy confirmed that the next qualification sequence, scheduled for the current quarter in accordance with the calendar announced during the summer, will focus on the production of mobility-grade hydrogen from the syngas produced by the H6. The company justified this choice by the level of purity required: mobility-grade hydrogen is, according to it, the most demanding application among those it targets. This stage should thus make it possible, according to Haffner Energy, to extend the validated performance of the H6 to other renewable molecules, particularly renewable methane and methanol.
