01 The solution

Independent engineering firm optimising industrial energy systems and decarbonising process heat. NORIA intervenes upstream of investment decisions: site opportunity study, comparison of the candidate technical configurations, then support of the implementation partners through to commissioning.

02 Technology principle

A method based on an hour-by-hour model of the site and on price and consumption scenarios, in order to compare the possible configurations (electrification, waste-heat recovery, thermal storage, low-carbon steam, multi-energy systems) and select the one that minimises the cost of heat while reducing emissions. Three stages: Study, Choose, Optimise.

01 The solution

Producing cooling from low-temperature waste heat.

02 Technology principle

Water adsorption in patented porous materials captures and stores heat before converting it into useful cooling.

01 The solution

Electric thermal management producing heating and cooling simultaneously.

02 Technology principle

ECOFICIENT uses mechanical vapour compression in a closed loop that captures, stores and redistributes waste heat.

01 The solution

An industrial heat pump producing steam, hot air or superheated water.

02 Technology principle

A proprietary centrifugal compressor and optimised heat exchangers upgrade waste heat from 30–80°C to useful heat at up to 200°C.

01 The solution

A low-carbon industrial boiler fuelled by recycled iron powder.

02 Technology principle

Iron powder oxidises to produce heat; the resulting oxide can then be regenerated using green hydrogen.

01 The solution

ORC modules and micro-turbomachinery for energy and hydrogen applications.

02 Technology principle

02 Technology principle

ECOSTILL concentrates and distils effluents at low temperature using humidification–dehumidification, with no compressor or vacuum pump.

01 The solution

A high-temperature industrial heat pump with thermal storage.

02 Technology principle

The heat pump raises the temperature to as much as 300°C while integrated storage retains surplus energy and releases it when required.

01 The solution

Very-high-temperature industrial heating using a heat pump.

02 Technology principle

A helium-based heat pump upgrades waste or ambient heat to deliver useful heat at temperatures of up to 550°C.

01 The solution

02 Technology principle

Eco-Stock® captures and stores high-temperature waste heat, then releases it as useful heat or electricity.

01 The solution

Large-scale electricity storage through thermal conversion.

02 Technology principle

A Carnot battery converts electricity into heat stored in rocks or ceramics, then converts that heat back into dispatchable electricity.

01 The solution

Recovering pressure energy from gas networks.

02 Technology principle

A free-piston expander and linear generators convert gas expansion into useful work, cooling or electricity.

01 The solution

01 The solution

Electricity generation from industrial waste heat using TURBOSOL and complementary technologies.

02 Technology principle

A thermodynamic loop transfers waste heat to a turbine and generator; Hevatech adapts the architecture to the source temperature and industrial use case.

01 The solution

High-power thermodynamic machines that recover industrial waste energy.

02 Technology principle

Depending on the requirement, ORC modules generate electricity, heat pumps upgrade low-grade heat and turboexpanders recover the energy released by gas expansion.

01 The solution

02 Technology principle

An external-combustion Ericsson engine with a liquid piston converts available heat into electricity.

01 The solution

Heat recovery and pollution removal from air or flue gases.

02 Technology principle

Direct contact between gas and water transfers heat and matter, washes the gas stream and then removes pollutants as the water is regenerated.

01 The solution
