Bioenergy co-products derived from microalgae biomass via thermochemical conversion - Life cycle energy balances and CO2 emissions

- An experimental study of thermochemical conversion of microalgae was carried out.
- Energy balance and efficiency of co-products char, bio-oil and gas was determined.
- Energy balance equations were established for process life cycle efficiencies.
- Comparisons were made with other energy indicators from literature.
- Life cycle CO2 results displayed more CO2 emissions released than absorbed.
