Fermentative Hydrogen Production. Lignocellulosic biomass is an attractive resource for hydrogen production via dark fermentation due to its abundance and high sugar content (~40% cellulose and ~30% hemicellulose).The primary research focus of our group is to make hydrogen production more economical by addressing the high cost of biomass feedstock and the low hydrogen molar yield (mol H2/mol
Biohydrogen Production and Hybrid Process Development - 1st

Biohydrogen Production - an overview | ScienceDirect Topics
Biohydrogen production technology is the process of catalyzing hydrogen production by microorganisms through light energy or fermentation and taking organic compounds in nature as substrate at normal temperature and in a normal-pressure aqueous solution. Compared with conventional hydrogen production methods such as the chemical or electrochemical method, which need a high-temperature or pressure environment, it has the following characteristics: (1) The reaction conditions are mild.
Biohydrogen from activated sludge from textile wastewater
Dec 01, 2018 · The production of biohydrogen was continuous and constant for the last 82 days until termination of the investigation. Acknowledgments An expression of gratitude is affirmed to the Under-Secretary of Control and Nuclear Applications (SCAN) of the Ministry of Electricity and Renewable Energy of Ecuador.
Biohydrogen production from microalgae—Major - Wiley
Nov 29, 2020 · Current hydrogen production mainly relies on fossil fuels and is usually energy and CO 2-emission intensive, thus the use of fossil fuel-derived hydrogen as a carbon-free fuel source is fallacious. Biohydrogen production can be achieved via microbial methods, and the use of microalgae for hydrogen production is outstanding due to the carbon
Frontiers | Biohydrogen Production From Biomass Sources
Another study (Melis and Happe, 2001), which assumes biohydrogen is produced 100% by photosynthesis, found that with a plant running at half capacity and an estimated production rate of 80 kg biohydrogen acre −1 day −1, biohydrogen would cost about $2.80 kg −1 which can be competitive with gasoline (Jiménez-Llanos et al., 2020).
Microalgae: The Future Supply House of Biohydrogen and Biogas
There are also some ways to improve the efficiency of biohydrogen production, such as microalgae-bacteria coupling biohydrogen production, adding sodium bisulfite (NaHSO 3), mixotrophic culture (adding sodium acetate as carbon source, producing carbohydrates for dark-fermentation-H 2 production) and immobilization of microalgae cells to improve
