Advanced direct biogas fuel processor for robust and cost-effective decentralised hydrogen production

Periodic Reporting for period 2 - BIOROBURplus (Advanced direct biogas fuel processor for robust and cost-effective decentralised hydrogenproduction)

Reporting period: 2018-07-01 to 2019-06-30

There is a need to increase the share of renewable resources in final energy consumption and achieve increases in energy efficiency. Hydrogen production from low carbon sources represents a valuable possibility to promote the decarbonisation of the energy system in a sustainable way. In this context, the specific challenge of BioRoburplus, is to demonstrate the potentials and sustainable utilization of biogas as renewable fuel for a decentralized production biohydrogen in a compact and efficient reforming.
The BioRoburplus project will develop a pre-commercial oxidative steam reformer (OSR) for sustainable and decentralized hydrogen production from biogas with no preliminary removal of CO2. The TRL6 demo-plant will deliver at least 50 Nm3/h (107 kg/day) of H2 at 99.9% purity and 1.5 bar with an energy efficiency conversion of 80% on a HHV basis. The ways to reach this objective are: i) high thermal integration, ii) PSA (pressure swing adsorption) offgas exploitation for reformer feed preheating, iii) power consumption minimization through CO2 removal prior to the PSA.
BioroburPlus has the ambitious target of exploiting biogas for the production of hydrogen. The main advantages of the BioroburPlus concept are: i) the avoidance of any preliminary CO2 separation from biogas, through a robust biogas reforming; ii) the integration of the purification process of hydrogen generation and the exploitation of the off-gases to thermally self-sustain the above-mentioned reforming, in order to achieve an unprecedented energy process efficiency.

The potential impacts of the successful demonstration of the BioroburPlus concept are all environmentally relevant:
the exploitation of biogas to produce hydrogen displaces the needs for the corresponding amount of fossil methane, and thus its associated CO2 emissions generated within methane reforming.

Moreover, the economical impacts are related to the high added value exploitation of biogas producers, with the remuneration of several decentralized actors in this field. Hence, this feature allows companies and consortia involved in bio-wastes treatment, to obtain a product (i.e. hydrogen) of higher remuneration than biogas, in a renewable way.

Finally, the adoption of the BioroburPlus framework has positive societal impacts for the communities involved in bio-wastes treatment since, beside the valorization of small producers, it allows the avoidance of large plants for hydrogen production, replaced instead by small decentralized ones, characterized by a higher social acceptance.
