New EU funded research will build a novel more efficient cogeneration engine running on renewables

For immediate release – A new EU research project will design a novel small-scale cogeneration engine using biomass to produce heat and electricity, which could mainstream renewables in the heating and cooling sector. The project, called SmartCHP, has been launched today in Brussels by ten partners including European industrial companies, Universities and innovation experts, under the coordination of BTG Biomass Technology Group.

Bert van de Beld, Chief Technology Officer at BTG, said “Currently, the vast majority of cogeneration plants use natural gas and fossil fuels as their primary source. The SmartCHP system will provide a small-scale solution for hospitals, universities, municipal buildings and countless industrial users that would like to use an efficient alternative to fossil sources. With a market potential of € 4 billion, and an estimated 85 to 95% less Greenhouse Gas emissions compared to fossil fuels, the installation of the SmartCHP technology in Europe can bring new jobs, more renewables and mitigate climate change.

The main novelty is the use of fast pyrolysis bio-oil from woody and non-woody biomass in a converted diesel engine, which has been chosen for its high electrical efficiency (more than 40%). The engine will be designed to have high flexibility, meaning that it can easily operate with different loads and produce more electricity or more heat as demand changes. This will be made possible thanks to the integration of a boiler and the use of bio-oil rather than solid biomass. As the SmartCHP system is hybrid, it can also be integrated with variable renewables, such as wind and solar. When the electricity provided by wind and sun is unavailable, the engine starts working on biomass, securing the supply of renewables.

Fast pyrolysis has the advantage of being able to transform difficult-to-handle biomass of different nature – such as verge grass, bark and husks – into a clean and uniform bio-oil, which is easy to store and use for bioenergy. Besides, the new Renewable Energy Directive introduced sustainability criteria concerning biodiversity, emissions and low indirect land use change that will apply to all pyrolysis bio-oil with no exception. This makes sure its production and its use in the project is sustainable.

One of the main challenges of the project is that pyrolysis bio-oil is more corrosive and thick than diesel, contains more water and is therefore more difficult to ignite. Partners of the SmartCHP project will work on modifications to the engine and the ignition system of the bio-oil to overcome this issue. At the end of the project, partners will build a demonstration cogeneration unit capable of running continuously for up to 500 hours in realistic conditions.

Notes to editors

The SmartCHP project has received funding of €4 million from the European Union’s Horizon 2020 research and innovation programme under grant agreement nº 815259. It started in June 2019 and will run for 4 years. The partners are OWI Oel-Waerme-Institut, Abato Motoren, Exergia Energy and Environmental Consultants, Capax Environmental Services, Greenovate! Europe, Technical University of Eindhoven, Tehag Germany, Denmark Technical University, Dowel Management, under the coordination of BTG Biomass Technology Group.

What is cogeneration?

Cogeneration – also known as combined heat and power (CHP) – is the simultaneous production of heat and electricity from a single energy source. The great advantage of cogeneration is linked to the use of surplus heat to produce electricity, usually for the same facility where it is produced.

What is fast pyrolysis?

Fast pyrolysis transforms solid biomass into a liquid in just a few seconds. First, biomass is rapidly heated to around 500°C in the absence of air. An oily smoke is created, which is then condensed into a liquid bio-oil. After years of development the process is now applied on an industrial scale, converting large quantities of lignocellulosic (non-food) biomass into a dark-brown bio-oil.
