U.S. Navy Research Turns Seawater into Aviation Kerosene

Energy is not only the lifeblood of the country’s economic and social development, but also the material basis for military operations. Although the armies of all countries in the world are moving toward informatization, neither the power required for the informatized weapon system nor the kinetic energy required for mechanized equipment is currently directly or indirectly converted from traditional fossil fuels.

In order to change the excessive dependence of military operations on energy, the US Navy recently revealed a magical study, “Water to Oil,” which directly converts seawater into aviation kerosene.

This new technology is directly converted from seawater to produce JP-5 aviation kerosene, which is the standard fuel for the US Navy's jet carrier aircraft. According to the assumption, the technology is to extract carbon dioxide and hydrogen from seawater, and then use a special catalytic technology to synthesize them into water, heat and synthetic hydrocarbon fuels. In the future, this new technology will enable the fleet to independently produce fuel, reduce transportation costs and environmental risks, save on transportation costs, and reduce the risk of being “scratched” by energy-exporting countries. If the technology for extracting fuel from seawater is mature, escort warships of future aircraft carrier battle groups can also use this fuel, which will greatly enhance the maritime self-sustaining force of aircraft carrier formations, and even change the naval strategic structure to a large extent.

The emergence of this result is due to the recent vigorous development of a new military energy security reform in Western developed countries. This change will greatly change the shape of future wars.

The transformation of military energy is imminent

More than 5 billion gallons, with funding requirements of 13.2 billion U.S. dollars. This figure is in 2010, the US military's oil consumption in military operations, more than doubled from 10 years ago. In the next fiscal year of 2011, the U.S. Navy only used 15 supply vessels to transport nearly 600 million gallons of fuel for the fleet.

There is much more to pay for the implementation of energy security than to pay a heavier price. According to statistics from the US Military Transport Command, in 2010 alone, the ground fleet was attacked more than 1,100 times, which is not included in the attacks on the oil convoys from the frontier operational base to the patrol base.

These battlefield lessons taught Western countries’ troops to sit on their felts. They deeply feel that in the face of the many risks of energy security, if they can ensure the efficient and practical use of key energy, it is equivalent to increasing the effectiveness of combat operations. In a sense, in today's era, energy is fighting power.

To cope with energy security challenges and assist military transformation, the European and American countries’ military has paid great attention to strengthening top-level design in recent years. Military energy security issues have been included as a priority in strategic planning, regulations, policies, operations, and safeguard programs. Active research and development have been used cleaner. , Efficient diversification of alternative energy sources, to build a strong "green army" and promote changes in energy security.

In March 2008, the British government issued the first national security strategy report ever, listing six major incentives leading to insecurity. One of them was the issue of energy competition and the mobilization and allocation of military energy. According to the "Strategic Guide", "Defense Target", "National Defense Plan" and "Defense Industrial Policy" issued by the British Ministry of Defense, the requirements for energy saving and consumption reduction in the construction of military facilities, procurement of equipment R&D, and logistical support have been correspondingly proposed.

In the "Quadrennial Defense Review Report" (2010 edition) of the United States, for the first time, it is emphasized that the issue of energy security needs reform. In June 2010, the US Department of Defense established the Assistant Secretary of Defense for Combat Energy Work, aiming to strengthen the leadership of this work. In June 2011, the US Department of Defense promulgated the first "Operational Energy Strategy". In March 2012, it also issued a supporting implementation plan, requesting "more fighting, less energy consumption, more choices, less risk, and stronger capabilities." The "cost less" principle promotes the reform of the energy security model. At the same time, he further pointed out that in order to build and maintain the military strength of the 21st century, especially in the case of fiscal tightening, it is necessary to build a "green army", reduce dependence on petroleum fuels, and use various energy sources in a smarter way.

US media claimed that US Navy Secretary Ray McBurth had set a goal to use 50% of the Navy’s energy use alternative fuels by 2020, thereby reducing the Navy’s dependence on fossil fuels.

Rely on science and technology to promote new changes

As the primary productive force, science and technology play the role of accelerators and multipliers in the transformation of military energy security. In recent years, the armed forces of developed countries have focused on actively using advanced concepts and scientific and technological means to provide strong impetus for deepening changes in energy security.

Widely adopting equipment and energy-saving technologies The US military plans to reduce the energy consumption required for maritime operations by 15% by 2020, increase the utilization rate of flying energy by 10%, and increase the energy efficiency on the ground battlefield by 50%. In the past five years, the U.S. has invested 131 million U.S. dollars in research and development of energy-saving technologies in fuel systems and engines. It plans to gradually replace high-powered multi-purpose wheeled vehicles with high-efficiency fuel trucks and reduce the use of high-efficiency turbine engines to the next-generation long-range bombers. Fossil fuel consumption.

The US Navy has launched a “smart drive” approach that only runs the equipment systems necessary to safeguard a certain mission and optimizes the ship load balance so as to maximize fuel efficiency and achieve the goal of reducing fuel consumption by 10% per year. The WR-21 gas turbine engine used by the British Navy's Type 45 "Brave Class" destroyer can save 25% to 27% compared with the existing single-cycle gas turbine system. At the same time, the armed forces of developed countries pay attention to continuously increasing the utilization of simulators in the skill training of pilots, crews, vehicle drivers, and weapon operators, and improve measures such as improving the internal structure of transportation vehicles, optimizing loading modes and transportation routes, etc. To effectively reduce fuel consumption.

Actively develop the use of alternative fuels to defuse the risk of high oil prices and oil supply is interrupted unexpectedly, the developed countries the military is actively developing alternative fuels. The U.S. military proposed in its energy strategy paper that through efforts in the coming years, it is necessary to ensure that aircraft, ships, vehicles, and various types of safeguard equipment can use alternative fuels. In August 2008, the US Air Force F-15E "attack eagle" became the first fighter to fly synthetic fuels. Synthetic fuels can be synthesized from jet fuel and natural gas, coal, plants, and other crude oil substitutes in a 1:1 ratio. By developing such environmentally friendly alternative fuels, the US military is expected to reduce its traditional aviation fuel demand by 50% by 2016. The US Navy is also advancing the construction of the "green fleet" and it is planned that by 2016 all ships can use blends of biofuels and conventional oils.

The biofuel technology developed by the U.S. Army and Bell Energy Co., Ltd. can use bacteria to treat biodegradable waste, such as crop residues, animal residues and domestic waste, and then reprocessed to produce liquid, solid, and gaseous fuels, as well as electrical and thermal energy. . This will not only provide new energy needed materials, but also reduce the burden of disposal of waste, to avoid causing environmental pollution and damage, thus turning waste into treasure, killing two birds with one stone. In 2008, the British Ministry of Defense established the “Termination of Dependent Fossil Fuel Dependency” plan, which required measures such as: the warships will operate entirely on electricity, while the generators will be driven by synthetic fuels extracted from grass; the tanks will be driven by electricity, or The oil extracted from the weeds was used as fuel; the drone used hydrogen produced by the processing of algae and microorganisms as fuel to launch missiles.

The use of new flexible manufacturing electricity current, use a variety of non-polluting renewable energy to generate the required energy has become an alternative means quite promising. In order to implement the "green" construction plan, the British Army began piloting bioelectric power generation projects at units such as the Welsh Air Force Base, the Clyde Navy Base, and Bowenton Barracks. The U.S. military, in cooperation with relevant government departments and private companies, will design and construct a 500 megawatt solar power station in Irving Fortress, California (the US Army's largest training base). This will be the U.S. Army’s largest solar energy project.

The Navy plans to build a marine thermal power plant that uses seawater temperature differentials to drive turbine generators to produce electricity. At the Hawthorne military base in Nevada, the U.S. military plans to build a 30-megawatt geothermal power plant in December 2014 to supply electricity generated from natural resources such as underground steam and hot water, which will not only meet all the electricity needs of the site. You can also sell the rest to the commercial grid. In terms of energy security for field equipment, the military in developed countries is developing more portable and efficient battery devices. For example, anti-matter batteries are expected to be put into use in the next 20 years. Antimatter is a substance whose charge is reversed. A button-size antimatter energy is 123 times the energy used by the space shuttle when it takes off. It can provide 30 to 40 years of usefulness for a vehicle's motor vehicle off-road, weapon launch and communication. energy. The use of an anti-matter device will eliminate the need for power recharging of some equipment systems.

System construction green camp pointed out that the US military, the camp facilities are combat effectiveness of their homes, all future construction of houses should adopt design principles for sustainable development. The measures taken include the promotion of real-time monitoring systems for energy and water consumption, fine management of energy security at the site, implementation of changes in daylighting, cooling roofs, solar heating and storm water management, and saving water resources through improved water flow technology; Generator remote control device, turn off and turn on the power as needed, intelligent control of electrical energy, etc. Through the reconstruction of Lewisburg, Washington, the demand for drinking water in the camp was reduced by 30%, and the industrial heating and air-conditioning efficiency exceeded the national standard by 15% to 35%. On this basis, the U.S. military also put forward the goal of building "zero-energy" military facilities.

"Zero energy consumption" means that the energy or water used in the base camp area is not more than the amount of waste that is reduced and produced through recycling. The method of constructing a “zero-energy” base is to consider the factors such as energy use, waste degradation, and traffic travel in the camp area as a whole, and adopt an overall planning approach to integrate the functions of each building and its subsystems and equipment.

Efforts to improve the field energy security Modern battlefield practice shows that reducing the military’s reliance on long-distance supply of fuel can reduce the need for transportation support and thus mitigate the risk of attack on the supply line. In Afghanistan, the U.S. military built a solar-powered sentry post. The "portable hybrid power system" used in field conditions can generate 5 kilowatts of electricity using solar energy, wind energy, etc. Its application prospects have been confirmed in Iraqi military operations.

The portable energy-enhanced backpack system charges the battery through a 62-watt non-reflective solar panel that flexibly converts angles, and can power multinational military vehicles through NATO sockets or lighters. NATO’s military uses spray foam insulation to build a temporary structure in front of the combat base. Its dust-proof, heat-proof, cold-proof, and noise-proof features have been significantly enhanced, saving energy requirements by 50%. In order to meet the urgent needs of the battlefield and quickly install new tactical water purification systems, the production efficiency has been improved by more than 10 times compared to the traditional models. In addition, most of the laundry and shower facilities use water circulation technology, which effectively reduces the water demand of warfighters.
