“…Frankly speaking, any water electrolysis approach that yields “green hydrogen” is economically unviable in the current conditions [ 115 ]. Common (water solution) electrolysis is very expensive (the production cost is around USD 10 per kg of 96–98% gaseous H 2 ), while solid polymer membrane electrolysis is immensely expensive (around USD 27–32 per kg of 99.999% gaseous H 2 ) [ 116 ].…”

Few analytical or research works claim that the negative impact of improper use of ASEs may be comparable with that of hydrocarbons and sometimes even greater. It has become a common view that “green” energy (ASE) is clean, safe and environmentally friendly (eco-friendly) in contrast with “black” energy (hydrocarbons). We analyzed 144 works on systemic and/or comparative research of the modern and prospective ASE: biofuels, hydrogen, hydropower, nuclear power, wind power, solar power, geothermal power, oceanic thermal power, tidal power, wind wave power and nuclear fusion power. We performed our analysis within the Spaceship Earth paradigm. We conclude that there is no perfect ASE that is always eco-friendly. All ASEs may be dangerous to the planet considered as a closed and isolated unit (“spaceship”) if they are used in an inconsistent manner. This is not in the least a reason to deny them as prospective sources of energy. Using all ASEs in different proportions in various regions of the planet, where their harm to the planet and humanity can be minimized and, on the contrary, their efficiency maximized, would give humanity the opportunity to decarbonize the Earth, and make the energy transition in the most effective way.

Blending hydrogen into existing natural gas pipelines is considered the most feasible choice for long‐distance, large‐scale hydrogen transportation in the early stage of hydrogen economy development. To integrate the optimization of hydrogen‐blended natural gas pipeline network and subsequent hydrogen/natural gas separation process, this article presents a mixed‐integer nonlinear programming model, aiming to minimize the total annual project net cost. To tackle the computational complexity resulting from the large‐scale and nonlinear nature of practical design problems, a decomposition algorithm is tailored to the proposed model. Two case studies demonstrate that compared to stepwise model, the proposed pipeline‐separation integrated model offers economic benefits and practical value, incorporating separation processes and satisfying constraints of hydrogen demand, pressure and blending ratio requirements, which achieves an economically optimal design for both pipeline transportation and separation systems, and provides a viable solution for the broader application of hydrogen‐blended natural gas networks.
