Did you know?

Here you can find many interesting facts about cogeneration, bioenergy and, last but not least, the SmartCHP system. Scroll down to find out!

… that cogeneration is the most efficient way to generate heat and power?

What is CHP? Is it the same as cogeneration?

Cogeneration and CHP (combined heat and power) refer to the same thing: the simultaneous production of heat and electricity from a single energy source, which leads to its high overall efficiency.

The main advantages relate to efficiency and flexibility. CHP is the most efficient form of power generation as surplus thermal energy is recovered and used for heating. It can also change the ratio of electricity and heat produced to suit demand.

Does CHP use renewable energy?

The vast majority of cogeneration plants use natural gas and heavy fuel oils as their primary sources. But CHP running on renewable biomass is perfectly possible and increasingly common. Currently about 20% of cogeneration production in the EU comes from renewables.

Can I install a CHP system at home?

Though so-called ‘micro cogeneration’ units are available for domestic use, CHP is more suitable for larger buildings and blocks. Common uses would be for example in hotels, hospitals, universities, industry and for district heating.

... that bioenergy represents more than half of the renewable energy consumption in Europe?

How can bioenergy contribute to the energy transition?

Bioenergy already represents more than half of the consumption of renewable energy in Europe. It is also ideally suited to be used in combination with other types of renewable energy, for example by balancing intermittent production from wind and solar.

Is making energy from biomass really sustainable?

This has been a controversial topic and as a result, the EU has developed very strict sustainability criteria for bioenergy, taking into account factors like greenhouse emissions, and its impact on biodiversity and land-use.

What is fast pyrolysis bio-oil?

Fast pyrolysis bio-oil (FPBO) is a clean and uniform bio-oil which is easy to store and use for bioenergy, and can also be further upgraded to bio-based chemicals. It is produced through a process called fast pyrolysis in which solid biomass is rapidly heated to 500°C in the absence of air. It can be applied to a wide range of difficult-to-handle biomass such as verge grass, bark and husks.

What is the advantage of liquid biofuels?

Liquid biofuels such as fast pyrolysis bio-oil have a much higher energy density than solid biomass. Their physical properties also make it easier to rapidly adjust the fuel load, which is essential to take advantage of the flexibility offered by CHP.

… that the SmartCHP system can reduce emissions by at least 80% compared to fossil fuels?

What is so ‘smart’ about SmartCHP?

A predictive, real-time dynamic system model will enable smart control of the SmartCHP unit. This means the heat-topower ratio can be automatically adjusted from 1:1 up to 10:1 to suit demand and balance variable intermittent renewables. Thanks to the combination of fast pyrolysis bio-oil and other renewables, the use of SmartCHP for heating and electricity can save between 85 and 95% greenhouse gas emissions compared to fossil fuels.

What type of cogeneration unit is SmartCHP?

The SmartCHP system includes a modified diesel engine, a flue gas boiler, a flue gas control and a smart control unit. The diesel engine has been chosen for its high electrical efficiency (more than 40%). Because pyrolysis bio-oil is more difficult to ignite than diesel, some modifications will need to be made to the engine.


Does SmartCHP cause particulate emissions?

Emissions are typically similar to heavy fuel oil. To ensure that gas and particulate matter emissions are below acceptable limits, and to increase overall efficiency, an innovative flue gas cleaning and heat recovery system will be developed.

What size is the SmartCHP unit?

The system being developed aims at implementation at a scale of 100 – 1,000 kWe. This is considered ‘small-scale’ and would be suitable for small industry, hotels, hospitals, etc. For larger requirements, multiple units could be combined. The demo unit built within the project will be capable of running continuously for up to 500 hours in realistic conditions.
