Widespread Interest

There is a widespread interest in the utilisation of the world's gas reserves, a considerable volume of which are located in remote areas and cannot be transported economically by pipeline. In addition the traditional market for such gas has been liquefied natural gas, but currently the market appears to be saturated. Consequently Bechtel Petroleum Inc. made a technical and economic analysis of processes which could be used to convert natural gas to transportation fuels. It was found that there is a number of new technologies which could be considered commercial and a considerable number that look promising but are not yet commercial.This paper presents the results of the economic analysis of the following five commercial or near commercial processes.Natural gas to methanol,Natural gas to methanol and gasoline,Natural gas to gasoline and diesel via the Fischer Tropsch process,Natural gas to gasoline and distillate (via extracted liquified petroleum gas), andOlefins direct to gasoline and distillate.For comparison purposes the economics of liquified natural gas were also developed.This comparison indicated that the conversion of olefins to transport fuels has a distinct economic advantage over the others. In addition this process has the flexibility of yielding varying percentages of gasoline and diesel according to market demand whereas some of the processes can produce only a single product. One disadvantage is that the olefins feedstock must be priced on a heating value basis comparable to natural gas and not for its alternative value in the manufacture of petrochemicals. There are situations in the world where refinery and chemical offgases containing olefins in dilute form could be priced competitively with natural gas.The conversion of extracted liquified petroleum gas from natural gas also looks promising, but it must be priced competitively with natural gas.The economic comparison highlighted the need for future basic research into the conversion of natural gas directly to transportation fuels rather than going through intermediate steps. Considerable research is currently being directed to these conversion processes. In addition there is also research being conducted to improve the economics of the commercial Fischer Tropsch conversion process.

Production of synthetic natural gas (SNG) offers an alternative way to valorize captured CO2 from energy intensive industrial processes or from a dedicated CO2 grid. This paper presents an energy-efficient way for synthetic natural gas production using captured CO2 and renewable hydrogen. Considering several renewable hydrogen production sources, a techno-economic analysis was performed to find a promising path toward its practical application. In the paper, the five possible renewable hydrogen sources (photo fermentation, dark fermentation, biomass gasification, bio photolysis, and PV electrolysis) were compared to the two reference cases (steam methane reforming and water electrolysis) from an economic stand point using key performance indicators. Possible hydrogen production capacities were also considered for the evaluation. From a technical point of view, the SNG process is an efficient process from both energy efficiency (about 57%) and CO2 conversion rate (99%). From the evaluated options, the photo-fermentation proved to be the most attractive with a levelized cost of synthetic natural gas of 18.62 €/GJ. Considering the production capacities, this option loses its advantageousness and biomass gasification becomes more attractive with a little higher levelized cost at 20.96 €/GJ. Both results present the option when no CO2 credit is considered. As presented, the CO2 credits significantly improve the key performance indicators, however, the SNG levelized cost is still higher than natural gas prices.

Industrial anaerobic digestion requires low temperature thermal energy to heat the feedstock and maintain temperature conditions inside the reactor. In some cases, the thermal requirements are satisfied by burning part of the produced biogas in devoted boilers. However, part of the biogas can be saved by integrating thermal solar energy into the anaerobic digestion plant. We study the possibility of integrating solar thermal energy in biowaste mesophilic/thermophilic anaerobic digestion, with the aim of reducing the amount of biogas burnt for internal heating and increasing the amount of biogas, further upgraded to biomethane and injected into the natural gas grid. With respect to previously available studies that evaluated the possibility of integrating solar thermal energy in anaerobic digestion, we introduce the topic of economic sustainability by performing a preliminary and simplified economic analysis of the solar system, based only on the additional costs/revenues. The case of Italian economic incentives for biomethane injection into the natural gas grid—that are particularly favourable—is considered as reference case. The amount of saved biogas/biomethane, on an annual basis, is about 4–55% of the heat required by the gas boiler in the base case, without solar integration, depending on the different considered variables (mesophilic/thermophilic, solar field area, storage time, latitude, type of collector). Results of the economic analysis show that the economic sustainability can be reached only for some of the analysed conditions, using the less expensive collector, even if its efficiency allows lower biomethane savings. Future reduction of solar collector costs might improve the economic feasibility. However, when the payback time is calculated, excluding the Italian incentives and considering selling the biomethane at the natural gas price, its value is always higher than 10 years. Therefore, incentives mechanism is of great importance to support the economic sustainability of solar integration in biowaste anaerobic digestion producing biomethane.
