Mediactive Events, a partner of the Hyvolution 2026 Trade Show

To mark the 10th anniversary of Hyvolution, an international event dedicated to hydrogen organized by GL events, Mediactive Events supported the organizers in designing and coordinating the reception and participant management systems.

Originally conceived as a hybrid format combining a main trade show with an associated conference, the event required an organizational structure capable of simultaneously managing the centralized coordination of visitor flows and the segregation of actionable data for each organizing entity.

The event attracted nearly 12,100 professionals, with 400 exhibitors and brands participating, representing 65 countries, 30% of whom were international visitors. The setup included 25 international pavilions and delegations, as well as an associated conference, GAS Analysis, organized by the French College of Metrology (CFM), which was hosted within the trade show with its own dedicated areas and content.

A hybrid and modular design by Mediactive Events

To address these challenges, Mediactive Events built its solutions around Aloha Events, the group’s event CRM management platform. This approach facilitated the centralization of registration, invitations, and access workflows for attendees of both the trade show and the conference. The tool also ensured the required separation of databases for the two events while maintaining a common entry point and a shared badge, with the goal of creating a unified visitor experience and distinct operational tracking for the organizing teams.

This approach facilitated coordination across the event’s various formats, while ensuring a clear connection between the main trade show and the associated conference. Mediactive Events thus enabled organizers to track attendance, participant demographics, and logistical data, thereby ensuring seamless operations across all venues.

Centralized management and interoperable solutions

Against a backdrop of the hydrogen market’s gradual expansion, Hyvolution 2026 brought together an audience composed primarily of stakeholders directly involved in project implementation: manufacturers, energy companies, mobility operators, financiers, and institutional representatives. Discussions focused on the operationalization of applications and the viability of business models reaffirmed the trade show’s position as the leading platform for the core of the ecosystem. In this context, effective management of attendee flows and data reliability were key factors.

To address these challenges, Mediactive Events structured the entire system around a single management hub, ensuring consistency among the various solutions and the teams on-site. The Aloha Events platform served as the foundation of the system, supplemented by specific modules designed to manage:

This oversight simplified administrative and logistical management, minimized the risk of conflicts between systems and teams, while ensuring smooth operations at the entry points. The presence of a Mediactive Events project manager on site strengthened oversight by maintaining constant communication with the GL events and CFM teams and ensuring that all technical and organizational systems operated in a consistent and structured manner.

Support tailored to the challenges of an international trade show

Hyvolution 2026 stood out for the maturity of the projects on display and for an audience comprised primarily of stakeholders directly involved in the hydrogen value chain.

Given this context, Mediactive Events provided a structured solution to meet the organizers’ needs:

This use case demonstrates how Mediactive Events can tailor its solutions to international event formats, integrate multiple tools within an interoperable framework, and provide centralized management that meets the demands of a complex, multifaceted event.

A structured collaboration with the organizing teams

This initiative is the result of the ongoing collaboration between Mediactive Events and GL events on events with an international and sector-specific focus. Hyvolution is part of a broader initiative led by GreenTech+, a division of the GL events group dedicated to the fields of ecological innovation and sustainable development. This structure reflects the group’s commitment to supporting markets in transition by providing them with professional platforms designed to address their challenges in consolidation and industrialization.

In this context, Mediactive Events acts as an operational partner to ensure the security of the event structure and data, in line with the strategic objectives set by GreenTech+ and the organizing teams. The shared methodological approach makes it possible to anticipate the specific challenges of a format that combines a trade show and a conference, while ensuring clear governance of data flows, access, and databases.
