The present teachings provide multi-reformable fuel delivery systems and methods that can deliver, without the use of a liquid pump, any hydrocarbon fuel, i.e., a liquid or gaseous reformable fuel, for example, to at least one of a reformer, a vaporizer, a fuel cell stack, an afterburner and other assemblies and components of a fuel cell unit or system, More specifically, gas pressure can be used to control and deliver gaseous reformable fuels and/or liquid reformable fuels in the delivery systems and methods of the present teachings. The delivery systems and methods also can apply to the delivery of a liquid reactant such as water and gaseous reactants such as an oxygen-containing gas (e.g., air) and steam.

Process for the co-production of methanol and ammonia from a hydrocarbon feed without venting to the atmosphere carbon dioxide captured from the methanol or ammonia synthesis gas and without using expensive air separation units and water gas shift.

Methods and systems for producing bio-methanol can include anaerobic digestion of a biomass feedstock to produce biogas including methane and carbon dioxide, partial oxidation of the biogas with oxygen from water electrolysis to produce syngas, synthesizing bio-methanol from the syngas and hydrogen from the water electrolysis, storing the bio-methanol, intermittently using battery based electricity to power the electrolysis during peak electricity demand, and intermittently using renewable electricity from another source during off-peak demand. Electricity can also optionally be obtained by periodically combusting a portion of the bio-methanol. The techniques provide a route for the production of bio-methanol without the engagement of fossil fuels as feedstocks and mitigating fossil fuel derived greenhouse gas emissions from processing and utilization of transportation fuels and commercial or industrial alcohols.

The present disclosure provide for methods of reforming a hydrocarbon such as methane. In an aspect, when the method is driven via renewable energy (e.g., use of solar energy, wind energy, or other renewable energy) and coupled with zero-energy input product gas separation, this enables the capture of pure CO.sub.2 (i.e., carbon sequestration) and carbon-neutral utilization of methane can be achieved. As a result, the present disclosure can provide for a method to reform methane with zero-energy input product gas separation.
