“…A brief discussion of hydrogen power options is merited, not least because this simplifies airside energy use calculations. Several options, including fuel cells [24] or hydrogen gas turbines [25] are currently available, all with very high TRL. For the proposed application, fuel cells are most suitable: they have a very high efficiency (50-60%), and a very high time between overhaul (TBO) of between 5000-25000 h [24]-a particular advantage at remote airfields or for marine UAVs.…”

Marine Cloud Brightening (MCB) is a proposed Solar Radiation Modification (SRM) geoengineering technique to enhance Marine Boundary Layer (MBL) cloud albedo. Extant proposals consider 10,000-100,000 autonomous ships spraying seawater, generating and dispersing sea salt nanoparticles. Alternatively, this paper proposes industrially manufacturing NaCl nanoparticles using ethanol anti-solvent brine precipitation. With desiccation, size optimization and narrowed size distribution, aerosol mass flux reduces by 500x (17x for dry mass flux). This facilitates Unmanned Aerial Vehicle delivery (e.g. MQ-9 Reaper Unmanned Aerial Vehicle). Increased speed and wake turbulence improves areal coverage per vehicle vs. ships --- reducing fleet size. Utilizing extant airframe designs improves vehicle Technology Readiness Level (TRL) --– potentially improving system operational cost (est. $40B per year) and lead time. This approach further reduces energy requirements (5x less), technical risk and system complexity. Increased readiness amplifies proliferation risk --- particularly for inexpensive regional heatwave and hurricane suppression --- making governance more urgent.

“…With the aim minimization of waste disposal and improving production of gas-turbine installation GE 6FA, it is considered the possibilities of usage of hydrogen as a major fuel, for implementation of the given task it is used program complex ASGCPT, as well as in this article it is considered perspective direction of utilization of CO 2 with the usage of high-qualified technology and its future utilization. Special peculiarities of research [6] that is focused on burning hydrogen in the gas-turbine GE 6 FA, for this reason authors used program complex ASGCPT, with the help of that mathematical sample was produced. Within it is considered power level GTU from 40 till 77 MW.…”

Today, global warming and the increasing demand of people for electricity and thermal energy remain in the focus of attention of international organizations and scientists. For this reason, the use of hydrogen gas, which has high thermal conductivity and is considered a clean energy source, remains relevant today. In this scientific article, it is proposed to use hydrogen together with natural gas in a gas-turbine power plant under the conditions of Turkmenistan, if the fuel consumption in normal condition is 7.7 kg/s, based on the scientific research, fuel consumption is 7.52 kg/s when natural gas and hydrogen are supplied in a ratio of 1%, the amount of natural gas saved was equal to 2.597%, when natural gas and hydrogen were given in a ratio of 10%, the fuel consumption was 6.219 kg/s, the amount of natural gas saved was equal to 19.233%, when natural gas and hydrogen were supplied in a ratio of 20%, the values were 5.216 kg/s and 32.259%, respectively. Also, as a result of the studied scientific sources, it was found that when natural gas and hydrogen are supplied in a ratio of up to 20%, it is not necessary to make any changes to the design of the turbine.
