“…This process uses about 13–18% of the hydrogen's lower heating value. Saias, Roumeliotis, Goulos, Pachidis, and Bacic 68 also mentioned that 11–13% of hydrogen energy will be used to compress hydrogen gas. Almost 2.21 kW h kg −1 energy is needed to compress hydrogen from 0.1 MPa to 80 MPa.…”

“…First, compressed hydrogen must be stored at very high pressures, namely between 350 and 700 bars. Next, LH 2 must be stored at very low temperatures, i.e., 20 K. In these engines, NO x is formed too, because of the high temperature of combustion [8][9][10].…”

Hydrogen is a prospective energy carrier because there are practically no gaseous emissions of greenhouse gases in the atmosphere during its use as a fuel. The great benefit of hydrogen being a practically inexhaustible carbon-free fuel makes it an attractive alternative to fossil fuels. I.e., there is a circular process of energy recovery and use. Another big advantage of hydrogen as a fuel is its high energy content per unit mass compared to fossil fuels. Nowadays, hydrogen is broadly used as fuel in transport, including fuel cell applications, as a raw material in industry, and as an energy carrier for energy storage. The mass exploitation of hydrogen in energy production and industry poses some important challenges. First, there is a high price for its production compared to the price of most fossil fuels. Next, the adopted traditional methods for hydrogen production, like water splitting by electrolysis and methane reforming, lead to the additional charging of the atmosphere with carbon dioxide, which is a greenhouse gas. This fact prompts the use of renewable energy sources for electrolytic hydrogen production, like solar and wind energy, hydropower, etc. An important step in reducing the price of hydrogen as a fuel is the optimal design of supply chains for its production, distribution, and use. Another group of challenges hindering broad hydrogen utilization are storage and safety. We discuss some of the obstacles to broad hydrogen application and argue that they should be overcome by new production and storage technologies. The present review summarizes the new achievements in hydrogen application, production, and storage. The approach of optimization of supply chains for hydrogen production and distribution is considered, too.

“…Urban Air Mobility (UAM) has a potential to transform transportation of people and goods in congested cities [1] while potentially reducing ground traffic. A key enabler of this technology is a class of zero carbon emission eVTOL aircraft concepts [2], many based on tiltrotor, tiltduct or tiltwing vehicle configurations powered by batteries or by making use of zero carbon fuel like hydrogen [3]. However, the lower energy density of energy storage options relative to liquid carbon based fuels restrict the operational range, hover time and cruise speeds.…”

This paper investigates robust tube-based Model Predictive Control (MPC) of a tiltwing Vertical Take-Off and Landing (VTOL) aircraft subject to wind disturbances and model uncertainty. Our approach is based on a Difference of Convex (DC) function decomposition of the dynamics to develop a computationally tractable optimisation with robust tubes for the system trajectories. We consider a case study of a VTOL aircraft subject to wind gusts and whose aerodynamics is defined from data.
