High-Efficiency Biomass Energy System for Energy-Independent Apartment Buildings

energyPrototypeTRL 5

Imagine a small power plant for an apartment building that turns wood pellets into both heat and electricity. It uses a special fuel cell that works like a high-tech battery in reverse to get more energy out of the fuel. By pairing this with solar panels, the building can almost run itself without needing the main power grid.

The business problem

What needed solving

Multi-family buildings struggle to achieve energy autonomy due to the inefficiency of small-scale heating and power systems and high emissions from traditional biomass burners.

The solution

What was built

A micro-scale biomass CHP system consisting of an updraft gasifier, a thermal/catalytic tar reformer, and a solid oxide fuel cell (SOFC) with integrated gas cleaning.

Real Estate Development
mid-size
Target: Multi-family residential developers

If you are a developer dealing with rising energy costs for apartment complexes — this project developed a biomass micro-CHP and PV system that allows buildings to be almost energy autonomous. It achieves overall efficiencies of more than 90%, reducing reliance on external grids.

Renewable Energy Equipment
SME
Target: Heating and Power (CHP) manufacturers

If you are a manufacturer dealing with strict emission laws — this project developed a gas cleaning system and SOFC that results in virtually zero CO and dust emissions. It also reduces NOx emissions by 55% to 65% compared to other biomass technologies.

Green Infrastructure
enterprise
Target: District heating and energy service providers

If you are a service provider dealing with the need for carbon-neutral heating — this project developed a 15 kW gasifier coupled with a 2.5 kWel SOFC. This setup provides a highly efficient way to supply heat and electricity for multi-family houses.
