Energy storage solutions
Five storage families, each suited to a different duration and duty. Choosing between them is an engineering question about your load, not a technology preference.
Overview
Overview
Glorinda delivers advanced energy storage systems to ensure stable and reliable power supply. Storage has stopped being an add-on to renewable projects and become the component that determines whether they are worth building — and on industrial sites, it is increasingly what makes self-generation and demand management viable.
Our technologies cover hydrogen storage, thermal storage, battery energy storage systems (BESS), mechanical storage and pump-turbine storage. They are not interchangeable. Duration, cycle frequency, round-trip efficiency, footprint, safety case and what the stored energy is eventually used for all point to different answers.
Detail
The five families
Hydrogen storage
For long-duration storage and for energy that has to be moved rather than held. Also the route where the end use is not electricity but a fuel or a chemical feedstock. In photovoltaic systems, hydrogen tanks are one of the two storage routes we use.
Thermal storage
Where the load is heat, storing heat is far more efficient than converting it twice. In concentrated solar power, molten salt storage is the primary means of storing energy and it is what overcomes the greatest weakness of solar thermal systems.

Short-duration shifting, frequency response and power quality. The default for sub-daily duties, and the storage route used alongside photovoltaic generation.
Mechanical storage
Where cycle life and safety matter more than energy density, and where a mechanical system can be maintained by the people already on site.
Pump-turbine storage
Bulk long-duration storage where the topography allows. Still the most cost-effective form of large-scale storage, and closely related to our hydropower engineering.

Choosing between them
Start from the duty, not the technology
Four questions settle most storage decisions:
- How long? Minutes and hours point to batteries. Days point to pumped or thermal. Weeks and seasons point to hydrogen.
- How often? Daily cycling rewards high round-trip efficiency and long cycle life. Occasional deep discharge does not.
- What comes out? If the load is heat, store heat. If the load is a fuel or a feedstock, hydrogen. If it is electricity, everything is in play.
- What can the site operate safely? The best technical answer that your team cannot maintain is the wrong answer.
Storage rarely arrives alone
Most storage projects we see are attached to something else: a solar or wind project whose output profile does not match the load, an industrial site managing demand charges, a thermal plant needing flexibility, or a grid connection that constrains export.
That means the storage decision is really a system decision, and it belongs in the feasibility study rather than in a later procurement round. Our engineering services cover exactly that stage.
Applications
Applications and challenges
Where it applies
- Firming solar and wind output to a dispatchable profile
- Molten salt heat storage on concentrated solar power plants
- Industrial demand charge management and peak shaving
- Grid frequency response and power quality
- Bulk long-duration storage via pump-turbine schemes
- Hydrogen production and storage for fuel or feedstock
- Backup and island-mode supply on critical sites
- Process heat storage where the load is thermal
Common challenges we are asked to solve
- A generation profile that does not match the load
- Grid export constrained by connection capacity
- Demand charges dominating the electricity bill
- Storage sized after the generation instead of with it
- Safety case and permitting for battery or hydrogen installations
- Round-trip efficiency assumptions that do not survive real duty cycles
FAQ
Frequently asked questions
Which storage technology should we choose?
Duration and duty decide it. Batteries for minutes to hours and frequent cycling; thermal where the load is heat; pump-turbine for bulk long duration where topography allows; hydrogen for long duration or where the energy has to be moved; mechanical where cycle life and safety dominate.
Do you supply battery systems?
Battery energy storage systems are one of the five families we deliver. As with our other products, systems are developed under the Glorinda brand and manufactured by qualified OEM partners, with Glorinda controlling specification, quality control and integration.
How does molten salt storage work on a CSP plant?
Heat collected by the collector field is stored in molten salt rather than converted immediately. The stored heat raises steam later, when demand requires it. It is how we overcome the greatest weakness of solar thermal systems.
Can storage be financed under your project finance framework?
Energy efficiency and recovery solutions and renewable energy projects are eligible project types under the German authority-backed framework, for total project values between €20m and €350m. Storage attached to such a project would be assessed as part of it.
