“…As a result of human activity, greenhouse gas emissions have increased since coal, oil, and gas combustion produces most carbon dioxide. Since the late 19th century, global temperatures have risen by 0.6 degrees Celsius and 0.2 to 0.3 degrees in the previous 25 years (National Oceanic and Atmospheric Administration) [11]. Despite this, the world's electric power consumption continues to grow at an alarming rate.…”

Renewable technologies are technically viable and economically attractive; traditional energy technology receives many investment dollars. This study examines the integration of renewable energy sources using functions that associate emissions with power generation; traditional producing units can represent these emissions. The environment friendly design has become a significant concern in the first decade of the 21st century. As a result of climate change and a limited supply of traditional energy sources (fossil fuel), the world needs to take renewable energy seriously. Renewable sources of energy are derived from the energy flow that occurs naturally in a continual manner. Many people define renewability as the ability to regenerate at a rate equal to or faster than a given energy source's depletion rate. Currently, fossil fuels are used to meet most energy needs, which should be replaced in the future by cleaner energy sources, such as renewables or nuclear energy. Building integration systems aim to replace a building element with a solar panel array to boost the RES system's viability. Renewable energy sources can be used to lessen the use of fossil fuels when certain criteria are satisfied. The use of renewable energy sources in buildings has well-understood environmental and economic benefits in this study. By relying on sustainable sources of energy, we can save as much energy as feasible.

Innovative and sustainable energy technologies are needed in the transition of energy toward a circular economy. Because of the use of renewable energy and carbon utilization, power-to-gas could be a cutting-edge technology that supports the circular model in future sustainable energy markets. However, this technology faces new technical and socio-economic challenges. The use of power-to-gas is limited because of barriers that limit the mobilization of investment capital. In addition, social and economic impacts on the territories in which these facilities are located are under study. In this context, the aims of this paper are: (i) To explore the determinants and barriers for power-to-gas technology to enhance the understanding of investment in innovative energy technologies; and (ii) to support effective policymaking and energy companies’ decision-making processes. This study defines and measures, from a circular economy perspective, the main impacts of the deployment of this technology on a territory in terms of volume of investment, employment generation, and CO2 capture. The study also provides a simplified methodology to contribute to the analysis of the use of power-to-gas. Finally, it improves the knowledge of the socio-economic impact of this cutting-edge technology for the transition of energy to a zero-emission scenario.

“…The Sabatier process, named after the French chemists Paul Sabatier and Jean-Baptiste Senderens who reported it in 1902 [1], is given by the reversible exothermic reaction This reaction has been investigated, e.g., in the context of in situ resource utilization on mars [2,3], for life-support systems on the ISS [4], and it is also used for power-to-gas applications [5,6], and cogeneration systems [7,8]. An overview over these and various other applications can be found, e.g., in [9].…”

We consider the optimization of a chemical microchannel reactor by means of PDE-constrained optimization techniques, using the example of the Sabatier reaction. To model the chemically reacting flow in the microchannels, we introduce a three- and a one-dimensional model. As these are given by strongly coupled and highly nonlinear systems of partial differential equations (PDEs), we present our software package cashocs which implements the adjoint approach and facilitates the numerical solution of the subsequent optimization problems. We solve a parameter identification problem numerically to determine necessary kinetic parameters for the models from experimental data given in the literature. The obtained results show excellent agreement to the measurements. Finally, we present two optimization problems for optimizing the reactor’s product yield. First, we use a tracking-type cost functional to maximize the reactant conversion, keep the flow rate of the reactor fixed, and use its wall temperature as optimization variable. Second, we consider the wall temperature and the inlet gas velocity as optimization variables, use an objective functional for maximizing the flow rate in the reactor, and ensure the quality of the product by means of a state constraint. The results obtained from solving these problems numerically show great potential for improving the design of the microreactor.
