Christian Breyer is Professor for Solar Economy at LUT University, Finland. His major expertise is research of technological and economic characteristics of renewable energy systems specializing for highly renewable energy systems, on a local but also global scale. Research includes integrated sector analyses with power, heat, transport, desalinati...
The global food demand is projected to significantly increase. To maintain global food security in the future, protein production needs to become more efficient regarding the use of limited land and water resources. Protein-rich biomass can be produced via direct air capture of CO2 with the help of H2-oxidizing bacteria and renewable electricity in...
The purpose of the research was to validate if the fast pyrolysis bio-oil (FPBO) from used wood would meet both the specifications set by the standard EN 16900–2017 for use of FPBO in industrial boilers and REACH requirements. Commercial used wood Class C was used for fast pyrolysis. The dominant material groups in the feedstock were (virgin) wood...
Direct air capture (DAC) is a technology for collecting and concentrating carbon dioxide from ambient air. If driven with renewable power, DAC is potentially a negative CO 2 emissions technology that can compensate emissions from non-point sources such as aviation, shipping and land-use change. This study presents the results of 10 days capture cam...
This work demonstrates hydrocarbon production directly from water, solar energy, and air-called SOLETAIR. The plant includes direct air capture (DAC) of carbon dioxide, hydrogen production by water electrolysis, and two-step synthesis bench-scale units that operate using grid-connected solar photovoltaic (PV) electricity. In addition, co-feeding of...

3D printing has revolutionized a number of industries but complete extension to electronics, robotics, and machines has yet to be realized. Current limitations are due to the absence of reliable and facile methods and materials for accessing conductive 3D printed materials. Traditional approaches to conducting nanocomposites (melt-mixing and soluti...
Neo-Carbon Energy is the largest renewable energy research in the Finnish history. We are creating a completely new energy system where the produced energy is emission-free,
cost-effective and independent. We are solving renewable energy’s flexible use, storage and distribution. This will revolutionise the entire energy field. The project is carrie...
In this study, direct air capture performance of polymeric adsorbent was studied by determining CO2-isotherms in very dilute conditions (CO2 partial pressure up to 5 mbar). The effect of cold conditions (0 °C and −10 °C) and humidity on the CO2 capacity was also studied. The experimental isotherms were used in temperature-dependent equilibrium mode...
In this paper, a proprietary CO2 sorbent is characterized and its sorption capacity determined. FTIR-ATR spectroscopy suggests that the sorbent is composed of polystyrene functionalized with primary amine. The Toth isotherm is found to best fit to laboratory-scale CO2 sorption data in partial pressure range of 0.1-5 mbar. Chemisorption dominates at...
The climate change forces us to shift from fossil to renewable resources. Integrated utilisation of biogenic CO2 is a promising way to produce sustainable raw materials and fuels. CO2 capture and utilisation (CCU) enables sustainable routes for carbon-based products and guiding the development to utilising especially biogenic instead of fossil CO2...

A new Cu-doped SrTiO3 photocatalyst was synthesized and characterized for uses in the visible-light photocatalytic production of hydrogen from water. The photocatalytic activity was assessed based on the characterization of the photocatalysts (band gap energy, surface area, crystallinity, and morphology) and the effects of varying together the calc...
To meet the increasing volume of waste to be treated via energy recovery, high SRF-energy-share fuel is being fired in conventional waste-to-energy facilities. In this work, corrosion related risk during firing of 70 e-% share (target fuel) is studied and compared against the base case fuel containing 50 e-% share. Cl and S concentration is highest...
Power-togas (P2G) technologies producing synthetic fuels have the potential to address the issue of intermittency of electricity from solar and wind farms, and simultaneously contribute to lower CO 2 concentration in the atmosphere. However it requires, among others, judicious technical selection of appropriate CO 2 capture and delivery technologie...
Increased use of biomass and waste fuels, and the consequent corrosion problem have led to an increased need to study and monitor the combustion processes. This study presents an extensive physical characterization of aerosol particles measured from a bubbling fluidized bed boiler with different fuel mixtures and optional ferric sulfate feeding. Th...
A staged equilibrium process model was developed for a bubbling fluidized bed boiler firing SRF, bark and sludge. The model was used to study the influence of sulfur addition strategies (S-pellet additive and peat co-firing) on the behavior of copper, bromine, and alkalis. Aerosol samples collected from the backpass of the boiler were used to valid...
Levels of PCDD/F production in a 140 MW,h bubbling fluidized bed boiler were measured. The boiler uses solid recovered fuel, bark and sludge. Homologue distribution patterns suggest the de novo mechanism is the main pathway for the generation of dioxin and furans in the post combustion zones of the boiler. Two modes of sulfur addition were tested t...
PCDD/F abatement strategies – sulfur pellet addition and peat co-combustion – were tested for a BFB boiler
facility utilizing SRF-bark-sludge as fuel. In this paper chemical and physical analyses of electrostatic
precipitator (ESP) fly ashes were used to explain the differences in the performance of these strategies.
These analyses revealed a diffe...
Ferric ion was introduced to the commercial photocatalyst P25 (Degussa) by ultrasonic wet impregnation technique. The concentration
of the dopant was varied from 0.0 to 3.0% Fe/Ti ratio. The doped TiO2 was then loaded to alumina balls using mechanical coating technique and followed by calcination in air at 400, 450, 500 and
550 °C. The fabricated p...

The main aim of the project is to demonstrate the utilization of biobased CO2 as a raw material for synthetic transportation fuels, biogas upgrading or industrial chemicals/products (so-called power-to-X process). The motivation is also that creation of sustainable and valuable products from bio-CO2 can give additional boost and new business opportunities for Finnish industry.
Investment on mobile hydrogen production unit will be made at VTT in order to integrate the existing VTT's synthesis unit and industrial CO2 streams as a complete pilot-scale research platform. The developed infrastructure will remain at VTT for later commercial disposal by interested companies.
Demonstrations with the developed platform will be conducted within e.g. bio-product mill and in biogas production. Additionally techno-economic feasibility studies of different products and markets as well as business opportunity analyses will be conducted in the project.
The goal is to find out most feasible utilization pathways for biobased CO2 as a raw material in Finnish biomass driven industry sectors and to identify the best business candidates for near- to medium-term deployment in Finland.
The main focus is on value chains for synthetic fuels, biogas upgrading, industrial chemicals and other valuable products utilising bio-CO2.
Study the production of microbial biomass and lipids from electricity, air, water and some nutrients. The project is funded by the Academy of Finland.
