Operating at high temperatures and in dusty environments is difficult but we have proven it can be done

The cement industry consumes 7% of the industrial energy demand and produces 8% of the world's CO₂. Pyramp system can help to reduce both at the same time.

Many high temperature industries struggle to recover radiated waste heat because it is difficult to put a device into contact with the process. The Pyramp TPV system solves this problem.

In a typical electric arc furnace steel production, approximately 45% of the input energy is wasted. Pyramp system can be adopted to improve their system efficiency.

There are some material requirements in different industries. We adapt our design to match these constraints

Some materials prohibit contact to preserve a certain finish. The Pyramp TPV system avoids this problem as it requires no physical contact with a hot object

Welcome to Pyramp

Welcome to Pyramp, a groundbreaking venture born out of research at the Technological University of Dublin, Ireland. Spearheading the transformation of waste heat into electricity, Pyramp’s innovative thermophotovoltaic (TPV) technology offers a modular, low-maintenance solution for high-temperature industries like cement, steel, glass, and ceramics. Pyramp is advancing towards its seed/spinout funding round after impressive industrial trials with world-leading companies from our targeted sectors. Join us in revolutionizing energy efficiency and sustainability

Empowering Industries Through Innovative Waste Heat Recovery

Pyramp emerged from a groundbreaking collaboration in 2019, leveraging Iftekhar Hussain’s PhD research. Key milestones include successful market validation, securing funding, and gaining traction with major industry players in the cement and glass industries.

Addressing the challenge of “difficult to abate” emissions, Pyramp’s thermophotovoltaic (TPV) technology converts industrial waste heat into electricity efficiently. The modular design and patented spectrally selective emitter material give Pyramp a strategic edge in high-temperature processes.

Leadership Team

We go beyond mere heat recovery; we actively contribute to the sustainability of high-temperature industries

Will a TPV device take energy from the process I care about?

Not if the location is appropriately selected. TPV converts Infrared light into electricity and so by design aims to minimise the absorption of heat from hot gasses.

How resilient is the device, what is the lifetime?

In the application for TPV there is very little UV. The lifespan depends on the location. So long as the device is designed to tolerate the environmental (dust, cycles, corrosion, etc) then a lifetime comparable to that of photovoltaic cells, i.e. circa 20 years, can be expected.

What is the power density and efficiency?

The power output and efficiency depend on the temperature of the heat source, the distance it is from the Pyramp device and the surrounding air temperature at the device. For cement, the power density is expected to be ~4kW/m² and for glass this can be as high if not higher than 12kW/m². Theoretical models for steel indicate similar power densities to glass.

At what temperature range can a TPV operate?

If the heat source is hot enough it will emit light, the hotter the heat source the higher the efficiency. Generally, the system power break-even point occurs at ~1000°C but this can be lower if the hot gases surrounding the device are colder. A suitable temperature range at this time is limited to between 1000°C and 1600°C.

Key Statistics

High-temperature process industries reject approximately 50% of their thermal energy into the environment as waste heat.

Cement, steel and glass industries are motivated to meet emission reduction targets because they are responsible for approximately 20% of the world’s CO₂ emissions.

Pyramp can cause 1200 million tonnes less carbon to be emitted into the atmosphere by 2050 if we succeed in recovering the waste heat from the world’s 3400 cement, steel and float glass plants.

A Pyramp panel has approximately 50 times more energy density than any solar PV module.

Waste heat recovery market is estimated to be approximately $60bn/year that is growing by 9% each year.
