Toulouse

Context

Water Horizon is a Toulouse-based deeptech start-up founded in 2017. With its proprietary thermochemical technologies, Water Horizon aims to become a major player in the decarbonization of industry. WH supports manufacturers in their energy transition across several verticals: waste heat recovery, heat storage and transport, and renewable cooling production.

With its mature technologies, WH transforms the landscape into an energy-positive territory.

6 GWh of energy delivered per year

DESCRIPTION

With its economic and industrial dynamism, the Toulouse region is ideal for

creating connections between waste heat producers and consumers.

The Waste-to-Energy Unit of the SETMI (Saint-Simon district of Toulouse) is a

Treatment center for household and other waste.

The facility processes approximately 240,000 tons of waste annually, producing electricity and heat.

A significant amount of this heat is recovered through several urban heating networks, allowing part of the Toulouse population to be heated with carbon-free and inexpensive heat. However, the highly differentiated consumption profiles between production and consumption limit recovery, so part of the heat is lost and released into the air. The Alex Jany Pool-Ice Rink Complex, located 15 km from the incinerator, is a very busy sports center that opened its doors in 2011. The proximity of the swimming pool and the ice rink creates a dual need for heating and cooling year-round, allowing for great energy efficiency.

With its «Move Heat to Cold» (MH2C) mobile thermal battery technology, Water Horizon will distribute renewable heat and cold from the waste heat of the UVE.

The MH2C battery is charged from the UVE's heat. Once the battery is full, it's transported to the Alex Jany complex to simultaneously distribute heat and cold. To ensure service continuity for the sports center, this project will include 2 batteries.

IMPACT

UVE of SETMI:

Better image

Reduced environmental impact

Upgrade and continuous innovation to meet changing regulations

Alex Jany Sports Complex

Lower operating and maintenance costs (boilers and chillers)

Reduction of GHG emissions

Precise temperature management, with no fluctuation (risk of ice thaw)

Localisation / Routing

TECHNOLOGY

For the past 7 years, WATER HORIZON has developed unique skills and technical expertise in waste heat recovery and renewable cooling production.

In Europe, industrial waste heat represents the equivalent of 100 nuclear reactors.

It is on the basis of this significant observation that Water Horizon has developed its Move Heat To Cold (MH2C) technology: recovering waste heat, storing it, transporting it, and distributing it to a distant consumer in the form of renewable cooling.

The MH2C battery recovers and values waste heat between 100°C and 200°C to redistribute it as heat but mainly as cold down to -10°C.

Water Horizon handles everything! Whether you're a producer or a consumer of waste heat, we'll find your partner, size the project, finance it, and operate it.
