Energy That Never Sleeps
Renewable power becomes more valuable when it is available when people and industries need it. Sai Bioenergy develops Long-duration Energy Storage systems (LDES) for renewable power.
Our platform includes Vanadium Redox Flow Batteries (VRFBs), Organic Flow Batteries (ORFBs), Sodium-ion systems and Supercapacitors. We match each technology to the project’s duration, safety, cycling and performance requirements.
Making Renewable Power More Flexible
Solar and wind generation changes across the day. And stops at sunset or when the wind stills. Energy storage captures available power and delivers it when demand rises.
Long-duration Energy Storage (LDES) helps renewable power serve evening demand. It supports reliable power during changing weather conditions. It strengthens energy resilience for critical facilities. And it also gives industries greater control over their energy use.
Build for Multi-hour Energy Delivery
As renewable penetration increases, power systems require storage solutions that deliver energy for longer durations (>4 hours) — not just rapid response. Long-duration energy storage supports delivery over several hours.
- Shifts renewable power from the time of generation to the time of demand.
- Supports overnight energy delivery.
- Strengthens resilience during extended grid events.
- Helps renewable projects deliver more predictable power.
- Also supports grid flexibility as renewable generation grows.
Battery Energy Storage Systems (BESS) and Long-duration Energy Storage (LDES) – Two Terms. One Clear Relationship.
Battery Energy Storage System describes the complete project system. A BESS includes the storage technology, power conversion system, controls and balance-of-plant equipment.
Long-Duration Energy Storage describes the system’s primary use. It focuses on delivering energy for longer periods.
Sai Bioenergy’s projects are delivered as BESS installations that provide long-duration energy storage.
Solutions Built for Every Energy Challenge
Different energy needs call for different storage technologies. Our portfolio supports project-specific design. We evaluate duration, safety, cycling, footprint, materials and lifecycle economics.
Vanadium Redox Flow Batteries (VRFBs)
VRFBs support long-duration stationary storage. Their power and energy capacity can be scaled independently.
- Larger stacks can increase power capacity.
- Larger electrolyte tanks can increase energy duration.
- Their aqueous electrolyte supports a strong safety profile.
- Their design supports frequent cycling and long operating life (25-30+ years)
- They are well suited to renewable integration, grid support and industrial energy.
Aqueous Organic Flow Batteries
ORFBs use an aqueous organic electrolyte system. They are made from carbon-based, earth-abundant organic molecules.
- They support long-duration stationary storage.
- Their chemistry has wider material choices. Quinone, for example, is derived from molecules found in plants.
- Their architecture can scale for renewable power projects and microgrids.
- They are being developed as a flexible platform for future storage applications.
Na⁺
Sodium-ion Systems
- Sodium-ion systems use widely available sodium-based materials.
- They support the development of more locally adaptable storage platforms.
- They can serve stationary energy applications.
- Our work focuses on chemistry, system design and commercial readiness.
GRID
Supercapacitors
- Supercapacitors provide rapid power delivery.
- They can support fast system response and power smoothing.
- They can complement long-duration storage in integrated energy systems.
- They are suitable for applications that require quick bursts of power.
Built for Endurance
Flow batteries store energy in liquid electrolytes. Their power capacity and energy capacity can be designed separately. This creates flexibility for projects with longer duration requirements.
Their architecture supports regular deep cycling. Electrolyte can be replenished or managed within the system. The aqueous chemistry supports strong safety characteristics. Their performance profile suits stationary renewable energy applications.
Flow batteries should be evaluated by application. Important factors include duration, safety, cycling, space and lifecycle economics.
Fast response and high round-trip efficiency over shorter durations. Modular, widely available and well suited to frequency response and peak shaving.
Non-flammable aqueous chemistry. Power and energy scaled independently. Negligible degradation across decades of daily deep cycling.
