Gasification and gas cleaning
Biomass gasification is one of VTT’s key technologies in the field of sustainable energy production. A major part of our activities are related to process development work, which we are able to carry out on laboratory- and pilot-scales with our unique test facilities and world-class expertise. In co-operation with our clients and industrial partners, we are also involved in several European demonstration and commercial projects. In addition, we perform techno-economic feasibility studies with a variety of gasification processes and applications.
Global climate change, soaring energy prices and diminishing fossil resources have provoked major interest in alternative and more sustainable fuels. However, due to the lack of a sufficient logistical infrastructure, the availability of cheap and good quality biomass has rapidly fallen. This has increased pressure to develop technologies capable of utilising wide ranges of feedstocks with a low, or even negative price. Because biomass is often sparse and a local resource, the size of production is usually confined to small or medium scale. Thus, it is important that the technology is able to achieve high efficiency while still maintaining low costs of production.
With gasification it is possible to upgrade a wide range of cheap and low-quality feedstock into valuable products and intermediates. In decentralised electricity production, synthesis gas can be converted to power with a high efficiency even on a small scale, while gasification of waste provides a cost-effective way to reduce CO2 emissions in existing power plants. In the transportation sector, gasification offers possibilities to produce second generation liquid biofuels in a sustainable manner from indigenous and renewable sources.
Almost every carbonaceous feedstock can be gasified to synthesis gas. In comparison to incineration, gasification enables the removal of harmful and corrosive impurities prior to combustion, making it possible to reach higher temperatures and higher power output. Second generation liquid biofuels produced via the gasification route contain less impurities than common fossil-based fuels and can therefore be mixed in any ratios and used in conventional engines.
