“…We recently aimed at partially filling this stated gap by performing a techno-environmental assessment of hydrogen from biomass, focusing on hydrogen production via anaerobic digestion of waste resources with high water content ("wet biomass") and subsequent reforming of biomethane with and without CCS and compared the results to hydrogen from natural gas reforming and electrolysis. 1 This assessment shows benefits of autothermal compared to steam reforming with CCS due to superior CO 2 capture rates, which results in lower life-cycle GHG emissions per unit of hydrogen produced. Furthermore, the use of wet biomass in combination with CCS allows for a net removal of CO 2 from the atmosphere.…”

“…The results of the wood-based hydrogen production chains are then compared with the natural gas/biomethane cases studied in our previous work (see Figure 1 for an overview on the different production pathways considered in this analysis). 1 The process analysis provides the main indicators required for the integrated techno-environmental modelling framework, which directly connects mass and energy flows from the process simulation with the Life Cycle Inventories (LCI). This integrated approach allows for the quantification of the environmental performance of many different cases based on consistent and physically sound data.…”

“…This approach is interesting not only as a bridging technology until H 2 from water electrolysis becomes cheaper and renewable energy can be generated at a large enough scale and low cost, but will likely remain the more cost-competitive option in many places like Europe or Japan [16]. In addition, replacing the fossil fuel source with renewable fuels like biomass or biogas can enable negative emissions [1,45].…”

Reforming of fossil fuels coupled with carbon capture and storage has the potential to produce low-carbon H2 at large scale and low cost. Adsorption is a potentially promising technology for two key separation tasks in this process: H2 purification and CO2 capture. In this work, we present equilibrium adsorption data of H2 and CH4 on zeolite 13X, in addition to the already established CO2 isotherms. Further, we carry out binary (CO2–CH4) and ternary (H2–CO2–CH4) breakthrough experiments at various pressures and temperatures to estimate transport parameters, assess the predictive capacity of our 1D column model, and compare different multi-component adsorption models. CO2 adsorbs strongly on zeolite 13X, CH4 adsorbs less, and H2 adsorbs very little. Thus, H2 breaks through first, CH4 second (first in the binary breakthrough experiments) and CO2 last. Linear driving force (LDF) mass transfer coefficients are estimated based on a single breakthrough experiment and mass transfer is found to be fast for H2, slower for CH4, and slowest for CO2. The LDF parameters can be used in a predictive manner for breakthrough experiments at varying pressures, temperatures, flows, and, though with lower accuracy, even compositions. Heat transfer inside the column is described well with a literature correlation, thus yielding an excellent agreement between simulated and measured column temperatures. Ideal and real adsorbed solution theories (IAST and RAST, respectively) both model the observed breakthrough composition profiles well, whereas extended isotherms are inferior for predicting the competitive behavior between CH4 and CO2 adsorption. This study provides the groundwork necessary for full cyclic experiments and their simulation.

“…This is significantly more expensive than the estimated cost of H 2 produced from SMR coupled with CCS of just above 2 USD/kg CO 2 or just below 3 in Japan [2,3]. Other advantages are the experience with already existing large scale H 2 production facilities, thus also making scale up easier, and the possibility to replace fossil with biogenic fuel, and thereby, when coupled with CCS, deliver negative lifecycle emissions [4].…”

Hydrogen as clean energy carrier is expected to play a key role in future low-carbon energy systems. In this paper, we demonstrate a new technology for coupling fossil-fuel based hydrogen production with carbon capture and storage (CCS): the integration of CO2 capture and H2 purification in a single vacuum pressure swing adsorption (VPSA) cycle. An eight step VPSA cycle is tested in a two-column lab-pilot for a ternary CO2–H2–CH4 stream representative of shifted steam methane reformer (SMR) syngas, while using commercial zeolite 13X as adsorbent. The cycle can co-purify CO2 and H2, thus reaching H2 purities up to 99.96%, CO2 purities up to 98.9%, CO2 recoveries up to 94.3% and H2 recoveries up to 81%. The key decision variables for adjusting the separation performance to reach the required targets are the heavy purge (HP) duration, the feed duration, the evacuation pressure and the flow rate of the light purge (LP). In contrast to that, the separation performance is rather insensitive towards small changes in feed composition and in HP inlet composition. Comparing the experimental results with simulation results shows that the model for describing multi-component adsorption is critical in determining the predictive capabilities of the column model. Here, the real adsorbed solution theory (RAST) is necessary to describe all experiments well, whereas neither extended isotherms nor the ideal adsorbed solution theory (IAST) can reproduce all effects observed experimentally.
