    Here’s an article posted in Financial Express.

    According to the article,

    • Ossus Biorenewables is a company that specializes in green hydrogen production
    • They have developed a technology that allows for on-demand, on-site hydrogen production
    • This technology is expected to revolutionize the hydrogen industry by providing a more efficient and sustainable solution

    Ossus Biorenewables’ bioreactor, OB HydraCel, works by using waste carbon in industrial effluents as the starting material for green hydrogen production. Here is a step-by-step explanation of the process:

    1. Target: The bioreactor targets the dilute organic content in effluents for biohydrogen production.
    2. Select: It selectively breaks down the organic content using electroactive microbial communities.
    3. Encapsulate: The microorganisms are encapsulated within the bioreactor.
    4. Produce: The bioreactor produces hydrogen gas using the encapsulated microorganisms and the waste carbon from the effluent.

    Some important features of the OB HydraCel are:

    1. Self-Powered: The bioreactor runs on localized power generated using an attached generator, ensuring it does not directly draw power from the site.
    2. Retrofittable Design: The bioreactor is designed to be retrofittable, ensuring it takes up no additional space and avoids pressure drops.
    3. Minimum Footprint: The bioreactor is designed to resemble pipelines at the site, ensuring a minimum footprint.
    4. Minimum Downtime: The bioreactor attaches directly to the effluent pipeline, acting as a bypass to ensure minimum downtime.

    This innovative bioreactor technology allows for on-demand, on-site green hydrogen gas generation, reducing the need for transportation and increasing efficiency.
