In the hospitality sector, guest comfort is paramount—and that means reliable, efficient cooling across hotels, theme parks, leisure centres and spas. But with electricity costs soaring, equipment under pressure, and sustainability targets tightening, keeping cool is becoming increasingly difficult to manage. EnergiVault, the cold thermal energy storage system from O-Hx, is offering a smarter way forward.
Cooling systems in hospitality venues are constantly in demand. From air-conditioned hotel rooms and conference suites to chilled water for spas and climate control in theme park attractions, these systems run day and night, especially during peak visitor seasons. But traditional chiller systems are energy-hungry, often oversized, and prone to short-cycling—leading to higher maintenance costs and premature equipment failure.
EnergiVault addresses all of this—head on.
By charging overnight using cheaper, off-peak electricity—or surplus on-site renewable generation—EnergiVault stores cold energy and then releases it during the day, when demand (and tariffs) are at their highest. This reduces the need to run chillers during peak hours, cutting electricity bills and easing strain on plant.
“Guest satisfaction depends on stable, consistent cooling,” explains the team at O-Hx. “But systems built for peak capacity are rarely efficient. EnergiVault brings control and flexibility—delivering cooling when it’s needed, without hammering your equipment or energy budget.”
The hospitality sector is already recognising the advantages:
-
Hotels can reduce daytime chiller use while keeping guests comfortable across rooms, restaurants and event spaces.
-
Theme parks and attractions benefit from smoother cooling loads, improved resilience, and lower energy overheads during peak attendance.
-
Leisure centres and spas maintain temperature-critical environments without excessive strain on cooling plant.
And it’s not just operational. The financial case is strong too. With typical paybacks of under four years, EnergiVault helps hospitality operators control costs while aligning with environmental goals. Reduced energy consumption, fewer breakdowns, and smarter load management mean better outcomes across the board.
The modular nature of EnergiVault makes it an ideal fit for both new builds and retrofits. Whether it’s a city-centre hotel, a resort complex, or a seasonal attraction, the system can be scaled to match any level of cooling demand—and integrated with solar or other on-site generation where available.
As the hospitality industry adapts to changing expectations, EnergiVault is helping operators deliver comfort, efficiency, and sustainability in equal measure. It’s not about replacing what works—it’s about making it work smarter.
