The Opportunity
Industrial Heat — The Largest Decarbonization Opportunity
Industrial Heat accounts for one of the largest operating costs and carbon emission sources in manufacturing. Generated predominantly from fossil fuels, process heat represents a significant share of both operating costs and industrial carbon emissions.
Gryneo helps industries replace fossil fuel-based heating with an integrated clean energy solution of Thermal Energy Storage, Solar, Battery Energy Storage and Waste Heat Recovery, delivering reliable industrial heat with lower operating costs and substantially lower carbon emissions.

Benefits
Helping Industries Transition Beyond Fossil Fuels
Strengthen Energy Security
Protect operations from fuel price volatility and grid instability. On-site storage keeps running when the grid, or your fuel supply, doesn’t.
20–35%
Lower Heating Costs
Capture renewable electricity and release it as a heat when your operation needs it — cutting your single largest energy line item.
Fuel-FiredGryneo TES
Lower Compliance Risk
As binding emission-intensity targets tighten under India’s new carbon market, on-site renewable heat is a direct, measurable lever against your compliance exposure — not just a cost saving.
Cut Fossil Fuels Dependency
Deliver reliable industrial heat and power from renewable energy sources, instead of fuel that keeps getting costlier and harder to secure.
Solutions
The Technologies Behind Every Solution
Every industry has different energy needs, but the objective is always the same—lower operating costs, reliable energy, and reduced carbon emissions. Gryneo designs, builds and integrates Thermal Energy Storage, Battery Energy Storage, Solar and Waste Heat Recovery into a single energy ecosystem, tailored to each application.
01
Clean Energy. Built for Scale.
Gryneo develops utility-scale and captive solar power projects that deliver reliable, low-cost renewable electricity for industries, commercial facilities and utilities. Every solution is optimized for long-term energy generation, seamless grid integration and maximum lifecycle value.
Applications
- Utility-scale solar parks
- Captive & group captive projects
- Open access solar
- Industrial renewable power
02
Store and Deliver High-Temperature Process Heat, 24×7
Industrial processes need heat around the clock — not just when renewable energy is available. Gryneo's Thermal Energy Storage system captures renewable electricity or recovered heat and stores it as high-temperature thermal energy, ready whenever your process calls for it. The system integrates seamlessly with existing steam, hot oil, thermic fluid and process heating systems without disrupting plant operations.
Applications
- Steam generation
- Thermic fluid heating
- Hot oil systems
- Process heating up to 900°C
03
Store Electricity, Reduce Peak Power Cost
Battery Energy Storage enables industries and utilities to store electricity when it is abundant and dispatch it when demand is highest. Gryneo designs intelligent storage solutions that improve renewable energy utilization, reduce peak demand and enhance grid reliability. Electricity supply and demand rarely line up — renewable generation often peaks at a different time than your plant, or the grid, needs it most. Gryneo installs BESS that store electricity when it's abundant and dispatch it when demand and prices are highest, improving renewable utilization, cutting peak demand charges and strengthening grid reliability.
Applications
- Peak shaving
- Energy shifting
- Backup power
- Grid support
04
Turning Waste Energy into Usable Energy
Large amounts of industrial heat are often lost through exhaust gases and process streams — energy that your plant has already paid for. Gryneo builds Waste Heat Recovery systems that capture this untapped energy and convert it into useful electricity or process heat, improving plant efficiency while reducing fuel consumption and emissions.
Applications
- Steam generation
- Power generation
- Process heating
- Heat recovery from furnaces, boilers and industrial processes

About Us
BuildingtheFutureofIndustrialEnergy
Gryneo is a clean energy developer focused on transforming how industries generate, store and consume energy. Through Thermal Energy Storage (TES), Solar, Battery Energy Storage (BESS) and Waste Heat Recovery (WHR), we help industries reduce operating costs, improve energy resilience and accelerate decarbonization.
Our solutions are designed around customer needs, not just technology — that means full asset ownership or a zero-capex path through Heat-as-a-Service (HaaS) or Energy-as-a-Service (EaaS). Gryneo delivers reliable, future-ready energy infrastructure that enables businesses to transition beyond fossil fuels. Gryneo pairs engineering execution with the commercial structuring to make each project bankable, not just buildable.
Leadership Forged Across Two Continents
Leadership Built on Engineering & Enterprise
Gryneo's leadership pairs two decades of disciplined capital-raising with hands-on project delivery — a combination that has moved over 700+ MW of renewable infrastructure from paper to production across Asia and Africa. It's this dual grounding, in both the financial architecture and the physical engineering of the energy transition, that shapes how Gryneo builds: projects that are bankable and buildable in equal measure.
