“…In Germany, it had been advocated by Asinger [26] already in the 1960s who had suggested its synthesisamongst other pathways -using the energy of nuclear high temperature reactors. Later on Olah [27] also proposed methanol as an infrastructure molecule for a post-oil world.…”

Future energy systems, which will rely on substantially higher contributions from regenerative supply pathways and which will be increasingly less dependent on fossil energy resources, will require high energy density storage compounds as strategic reserves and for seasonal storage. Hydrocarbons, such as oil and natural gas, are currently serving this purpose.These will also be options in future systems, but in that case, these compounds would have to be synthesized using some other form of energy. Thus, with decreasing importance of fossil resources, other storage compounds also seem to be viable, the most prominent ones under discussion, in addition to the ones mentioned, being hydrogen, methanol, and ethanol. In this contribution, the different storage compounds will be discussed, and their merits and drawbacks for large scale implementation will be compared.

“…The production and potential of methanol for replacing oil and natural gas in the framework of the "Methanol Economy" was discussed in some of our publications, [9][10][11][12] patents 13 and extensive monographs by our group and other researchers. 9,12,[14][15][16][17] The present comprehensive paper reports the chemistry and its significance of the selective, effective oxygenation of methane (natural gas) to methanol.…”

Single Step Bi-reforming and Oxidative Bi-reforming of Methane (Natural Gas) with Steam and Carbon Dioxide to Metgas (CO-2H₂) for Methanol Synthesis: Self-Sufficient Effective and Exclusive Oxygenation of Methane to Methanol with Oxygen

Catalysts based on suitable metal oxide supports, such as NiO/MgO and CoO/MgO, were shown to be active for single step bi-reforming, the combined steam and dry reforming of methane or natural gas with H2O and CO2 exclusively to metgas (CO-2H2) for efficient methanol synthesis. Reactions were carried out in a tubular flow reactor under pressures up to 42 bar at 830-910 °C. Using a CH4 to steam to CO2 ratio of ∼3:2:1 in the gas feed, the H2/CO ratio of 2:1 was achieved, which is desired for subsequent methanol synthesis. The needed 2/1 steam/CO2 feed ratio together with the reaction heat for the endothermic bi-reforming can be conveniently obtained by the complete combustion of a quarter part of the overall used methane (natural gas) with oxygen of the air (oxidative bi-reforming). Complete combustion of a part of methane followed by bi-reforming leads to the production of metgas (H2/CO in 2:1 mol ratio) for self-sufficient exclusive methanol synthesis. The long sought after but elusive efficient and selective oxygenation of methane to methanol is thus achieved in an effective and economic way without any oxidation byproduct formation according to CH4 + 1/2O2 → CH3OH.

If substantial amounts of CO 2 , which according to actual scenarios may in the future be captured from industrial processes and power generation, shall be utilized effectively, scalable energy efficient technologies will be required. Thus, a survey was performed to assess a large variety of applications utilizing CO 2 chemically (e.g., production of synthesis-gas, methanol synthesis), biologically (e.g., CO 2 as fertilizer in green houses, production of algae), or physically (enhancement of fossil fuel recovery, use as refrigerant). For each of the processes, material and energy balances were set up. Starting with pure CO 2 at standard conditions, expenditure for transport and further process specific treatment were included. Based on these calculations, the avoidance of greenhouse gas emissions by applying the discussed technologies was evaluated. Based on the currently available technologies, applications for enhanced fossil fuel recovery turn out to be most attractive regarding the potential of utilizing large quantities of CO 2 (total capacity > 1000 Gt CO 2 ) and producing significant amounts of marketable products on one hand and having good energy and material balances on the other hand (t CO 2 -emitted =t CO 2 -utilized < 0:2 -0:4). Nevertheless, large scale chemical fixation of CO 2 providing valuable products like fuels is worth considering, if carbon-free energy sources are used to provide the process energy and H 2 being essential as a reactant in a lot of chemical processes (e.g., production of DME: t CO 2 -emitted =t CO 2 -utilized > 0:34). Biological processes such as CO 2 fixation using microalgae look attractive as long as energy and CO 2 balance are considered. However, the development of effective photobioreactors for growing algae with low requirements for footprint area is a challenge.
