Allam proposed to realize problem of CO2 emissions by using supercritical CO2 cycle as working fluid with heating by carbon fuel burning in pure oxygen and then pumps CO2 into underground volumes remaining after oil production.Interest in the Allam cycle shows readiness for technological difficulties and high costs for combating CO2 accumulation in atmosphere. The formic acid cycle begins with the conversion of CO2 from the atmosphere or from flue gases to an aqueous solution and the electrochemical reduction of CO2 into formic acid. Formic acid is a convenient and safe energy storage for fuel cells, since the electrochemical process is reversible. In the reverse process (oxidation), the released CO2 can be immediately immobilized and further buried as a component of the building foam concrete. The formic acid cycle can serve as a "green" alternative to the dominant oil cycle of basic chemical production. It should be noted that even if the task of combating CO2 emissions and global warming will be no longer relevant, the value of the formic acid cycle will be preserved, since it solves a broader spectrum of tasks for the ecologization of energy generation and organic chemistry.
The Fischer-Tropsch process (F-T process) is known as a method of synthesizing organic products (including liquid fuel) from CO + H2 mixture gases (synthesis gas) using various catalysts. The interest in the F-T process is associated with the global struggle against carbon emissions. Earlier we noted that the electrochemical synthesis of formic acid from water and atmospheric CO2 can be a promising general scheme for obtaining "green fuel" with minus (negative) "carbonic effect" simultaneously "formate cycle" (synthesis of organic products from formic acid produced from atmospheric CO2) fuel has zero carbon balance. This synthesis is brought to efficiency, surpassing natural photosynthesis. Synthesized formic acid can be used as a fuel for fuel cells and as a hydrogen accumulator. A semiproduct of green fuel synthesis with zero carbon balance and synthetic organic chemical products with minus carbon balance (thanks to bonded carbon from atmospheric CO2). From an economical point the direct use of formic acid would be more rational (with the exception of one stage), without first carbon monoxide separation. From the point of view of the physical chemistry, it is necessary to take into account the relatively low reactivity of formic acid in comparison with carbon monoxide. The traditional way of activation, by applying high temperatures, high pressures and specific catalysts in gas phase. However, using electromagnetic activation may be a more interesting pathway. This aspect will be discussed in this work. The final selection of the method based on the results of bench scale should be made on the basis of a complex criterion of the rate of passage of the modified F-T process and economic indicators: equipment cost, and energy consumption in terms of the mass of final products, taking into account of their cost. In this case, it appears an alternative way of obtaining some final products without using fossil hydrocarbons.
The problem of using hydrogen as a coolant became actual before the concept of global warming and the struggle for decarbonization. Formate cycle allows solving problem of transportation and storage. New modified Fisher-Tropsh process. version is described and showed that most rational electromagnetic activation utilization for its implementation. More detailed problem nuclear energy is considered with Carlo Rubbia ideas usage. It is proposed to use subcritical reactor with torium nuclear fuel what ensure 100% safety. Floating Nuclear Chemical-Synthetic Facility (NChSF) of the open sea was considered.
