Research, Development and Innovation

At ENSO we believe we can only offer the best solutions if we are able to constantly do research, learning and looking for new answers that will enable us to progress. This is a fundamental activity, as its ability to create value benefits both our clients and the ENSO Group as a whole.

LIFE CO2 Int Bio

The companies Carburos Metálicos, ENSO O&M and Bioeléctrica de Garray, together with Fundación Patrimonio Natural de Castilla y León, have been executing the LIFE CO2-Int-Bio since June 2019 at Parque Empresarial del Medio Ambiente located in Garray (Soria). The main goal is to reduce the CO2 emissions in energy-intensive industrial sectors (commercial gas production in greenhouses with intensive farming), applying new methods or technologies through industrial integration and the creation of new chains of value related to CO2.

This pioneering initiative will integrate the operation of the biomass plant with a new facility to capture, scrub and use the CO2 issued and will establish synergies for optimising the industrial processes and generating new products, such as "green" CO2 for different uses.


The project has financial backing from the LIFE Climate Change Mitigation programme (LIFE18 CCM/ES/001094) and its own web page


The project is part of a more ambitious approach that is being completed with a thermal and electric integration and a final “Zero Waste” approach stage through the collection and use of ashes from the biomass plant in the manufacture of fertilisers.

LIFE Enerbioscrub Read more


With the ENERBIOSCRUB project, carried out between 2014 and 2018, we demonstrated that the harvesting of certain scrub areas for energy through mechanised techniques is technically and economically viable. We focus on the management of scrub mass by clearing and gathering biomass to use it in energy production, which also helps prevent wildfires and generate new resources for the local population. 



We also had to iron out non-technical aspects, such as the problems of forest ownership, heavy intervention from the state, the lack of regulation of biomass management and the lack of public support for forestry production and management. Care and conservation of scrubland is closely linked to its economic profitability, and it has been demonstrated that scrubland which generates wealth for the neighbouring population is less likely to burn. 





A future with more biodiversity, fewer forest fires, less population, and a low-carbon economy, requires policies that support the obtainment of products from scrublands to make them economically profitable, especially when here in Spain 70% of scrublands are privately owned. 


This project had European financial backing under the LIFE PROJECT ENV/ES/00660 contract and was implemented in As Pontes (A Coruña, Galicia), Garray (Soria, Castilla y León), Fabero (León, Castilla y León) and Las Navas del Marqués (Ávila, Castilla y León). We participated in its implementation together with CIEMAT, AGRESTA, AVEBIOM, AYTO FABERO, MONTES DE LAS NAVAS S.A., INIA, TRAGSA, BIOMASA FORESTAL and INTACTA.

CFD Read more


The RDI department of ENSO GES uses techniques of CFD (Computational Fluid Dynamics) in various aspects of the designs, particularly in fluid circulation, modelling of heat-exchange processes and combustion reactions. This means it can optimise the designs, thereby improving not only the thermal, mechanical and chemical performance of the equipment, but also detecting frequent phenomenologies such as erosion or vibrations. As our research as evolved, today we can also create numerical models to develop ad-hoc solutions beyond the conventional scope of CFD/FEM techniques. 


Applicable examples include:

Analysis, design-enhancement proposal and engineering of the solution to reduce erosion phenomena in an economiser of a fluid-bed biomass plant in Berlin, New Hampshire, USA.

Analysis and proposal for a solution to optimise the feed loss in a waste-heat boiler at Nestlé, Girona, Spain.

Projecting ourselves 20 years into the future

BiOxySorb Read more


BiOxySorb is a European project created at the Institute of Combustion of Stuttgart University (IFK), and had the participation of companies like UNIPER, LHOIST and the Ciudad de la Energía foundation (CIUDEN-Ponferrada) (insert link to our project), where we had also created the pulverised-coal-fired oxy-combustion boiler, which was used to carry out the industrial-scale testing of the project.




ENSO GES, as the technologist of the oxy-combustion boiler, acted as technical consultant with regard to:

  • the impact of combustion and steam generation on the equipment's thermal efficiency.

  • the emissions generated.

  • the impact of the fuels considered on the combustion mechanism.

  • operational support during testing.


The results were extremely interesting. We tested fuel mixtures at up to 30% of the thermal load (both white pellet and torrified pellet ) in regimens of both partial and total oxy-combustion.
