- **Summary:** Green Heat provides renewable industrial heat using high-temperature heat pumps (HT-HP) and biomass, with financing, design, implementation, operation and maintenance managed by White Energy through an ESCo/EPC Guaranteed Saving model.

## Green Heat overview

Green Heat is designed for companies that want to decarbonize process heat and reduce costs without tying up capital. It replaces methane boilers with renewable thermal-generation systems that recover waste heat and use green electricity or sustainable biomass.

Under an **ESCo – EPC (Energy Performance Contract) Guaranteed Saving** model, White Energy finances, designs, builds and manages high-efficiency renewable thermal systems based on HT-HP and biomass.

The service is presented as providing:

- renewable heat for hot water, superheated water or steam;
- guaranteed economic savings compared with the pre-intervention situation;
- access to **Energy Efficiency Certificates (TEE)**;
- reduced exposure to CO₂ costs linked to ETS2 by replacing methane;
- complete operation and maintenance (O&M) and management of incentive/TEE procedures.

## How the system works

Green Heat uses industrial high-temperature heat pumps to recover low-temperature heat above **50 °C** from industrial processes, cooling towers or chillers. The recovered heat is upgraded to useful temperatures above **80 °C**, and up to above **120 °C** for steam production.

The regenerated heat is then reused in industrial processes, eliminating or reducing the need for fossil fuels. The page states that this can reduce energy consumption and CO₂ emissions, decarbonize industrial thermal processes, enable TEE incentives and reduce exposure to ETS2 costs expected from 2027.

If waste heat is not available, Green Heat can use certified biomass as the primary source, or be combined with an internal heat network or renewable PPAs to supply the heat pump. The configuration is defined according to the production site and local energy availability.

## Target sectors

### Industrial materials

Green Heat systems can be built or renovated for facilities with high thermal demand. HT-HP or biomass solutions reuse waste heat, reduce costs and can access TEE incentives.

### Chemical industry

The service is intended for processes requiring thermal continuity and medium-to-high temperatures, replacing methane boilers with heat-pump or biomass systems while reducing emissions and improving overall efficiency.

[Chemical and pharmaceutical sector](https://weeg.it/soluzioni-energetiche-per-settori-aziendali/settore-chimico-farmaceutico/)

### Textile industry

Green Heat systems provide renewable, constant heat for dyeing, drying and finishing, with thermal recovery from machinery and reduced operating costs.

### Manufacturing

HT-HP systems serve production lines and complex industrial processes, supplying hot water and low-impact steam while optimizing energy costs and process-heat management.

[Manufacturing sector](https://weeg.it/soluzioni-energetiche-per-settori-aziendali/settore-manifatturiero/)

### Food industry

The service supports steam and hot-water production for processing, washing and sanitation, reducing gas use and improving supply-chain sustainability.

### Hospitality

The page also describes Green Heat applications for hospitality facilities, hotels and large residential buildings, providing renewable heating and domestic hot water while reducing energy costs and environmental impact.

## Case study: paper mill

### Initial situation

The paper mill had high methane consumption for producing superheated water and low-pressure steam used in paper drying.

### Intervention

White Energy installed a **2.8 MWt** industrial HT-HP system that recovers heat from exhaust-air flows and process water at about **55 °C**, upgrading it to **105 °C** for the drying lines.

The project was developed under an ESCo/EPC model with a dedicated SPV for financing, technical management and O&M. The plant uses electricity from renewable sources through a green PPA.

### Reported results

| Metric | Reported result |
|---|---:|
| Estimated total economic savings over 10 years | €11.5 million |
| CO₂ reduction | More than 5,200 tonnes/year |
| TEE recognition | 11 years, shared with the customer |
| EPC duration | 12 years |
| Investment | €2.6 million, fully borne by Whitenergy |

## Case study: dairy plant

### Initial situation

The dairy company had high methane consumption for process-water heating, washing and sanitation, alongside rising costs and a need to reduce Scope 1 emissions.

### Intervention

White Energy installed an automated **1.5 MWt biomass plant** fuelled by locally sourced wood chips and integrated it with a **600 kWt HT-HP** system that recovers heat from cooling circuits.

The system supplies hot water and steam at **90–120 °C**. The page states that it reduces gas consumption by **85%**. The project was implemented under an EPC model, fully financed and managed by White Energy, with remote monitoring and a performance guarantee.

### Reported results

| Metric | Reported result |
|---|---:|
| Total energy savings | More than 1,800 TEP/year |
| Thermal-cost reduction | 35% annual OPEX |
| CO₂ avoided | About 4,700 tonnes/year |
| TEE reporting duration | 10 years |
| Customer investment | €0; financed by Whitenergy |
| TEE | Shared with the customer |

## Frequently asked questions

### When is Green Heat preferable to a methane boiler?

The page identifies applications with available waste heat or continuous high thermal demand for hot water, superheated water or steam. It says the economic case becomes stronger when methane and CO₂ costs are high, when Scope 1 decarbonization is a target, or when a company wants to stabilize thermal costs over the next 10–15 years.

### How is an industrial HT-HP different from a conventional heat pump?

The page states that high-temperature heat pumps can operate at **120 °C and above**, producing process heat or low-pressure steam. They use industrial compressors, specific refrigerants and hot recovery sources such as process water, cooling towers and chillers.

### Can Green Heat be used without waste heat?

Yes. The page states that certified biomass can be used as the primary source, or the system can be combined with an internal heat network or renewable PPAs.

### Can the system completely replace gas?

The page states that, in most cases, HT-HP can cover base and intermediate thermal demand while biomass or hybrid systems cover peak loads, allowing gas consumption to be reduced by up to **90%** while maintaining production continuity and operating safety.
