Environmentally Sustainable Technology for Carbon Dioxide Utilization and Biohydrogen Production

Strategic Insights -

The Institute of Civil Engineering at St. Petersburg Polytechnic University has developed an innovative environmentally sustainable technology that utilizes microalgae to convert carbon dioxide from industrial emissions into biohydrogen, a promising renewable fuel. This technology, supervised by Professor Natalia Politaeva, has the potential to reduce harm from carbon dioxide emissions and increase energy efficiency in coal power plants. The system combines three functions: carbon dioxide capture, biomass processing, and hydrogen production, making it a unique and sustainable solution.

Key Takeaways:

  • The technology involves the use of bioponds where microalgae absorb carbon dioxide, forming biomass, which is then subjected to dark fermentation to obtain biohydrogen.
  • The biohydrogen produced can be used in cars, hydrogen fuel cells, or to generate electricity and heat.
  • Implementation of the technology in coal power plants will help reduce the harm from carbon dioxide emissions and increase the energy efficiency of enterprises.
  • The technology combines three functions: carbon dioxide capture, biomass processing, and hydrogen production, making it a unique and sustainable system.
  • The scientists plan to improve the technology after pilot implementation at an industrial facility.
  • The development was carried out under the supervision of Natalia Politaeva, professor at the Higher School of Hydraulic and Power Engineering.
  • The results of the study were published in the International Journal of Hydrogen Energy.

Statistics:

  • The technology combines three functions to produce biohydrogen, making it a unique and sustainable system.
  • The biohydrogen produced can be used in various applications, including vehicles, fuel cells, and electricity generation.
  • The implementation of the technology in coal power plants is expected to reduce carbon dioxide emissions and increase energy efficiency.
  • The technology has the potential to contribute to the reduction of greenhouse gas emissions and promote sustainable energy production.
