What You'll Learn
The US Navy is the world's largest consumer of diesel fuel
The Navy consumed 32% of the total energy used by the DoD, which equates to a rough estimate of 112,000 barrels of oil per day. This includes jet fuel, ground fuel, electricity, and other energy sources. The Navy's energy consumption represents 0.4% of the entire nation's energy consumption.
The Navy has acknowledged its dependence on oil and its need to reduce this reliance. Navy Secretary Ray Mabus has promoted the development of a "Great Green Fleet", a carrier strike group using only alternative fuels or nuclear power. The Navy hopes to reduce non-tactical petroleum use in its commercial fleet by 50% by 2015 and produce at least 50% of shore-based energy from alternative sources by 2050.
The Navy has also invested in renewable energy strategies, such as the Tactical Garbage to Energy Refinery Program, which converts waste into fuel, and the use of biofuels. The Navy's interest in biofuels is part of its goal to generate 50% of its energy from alternative sources by 2020. However, biofuels are more expensive than petroleum fuels, and the Navy must consider the cost and performance of these alternative fuels.

The Navy consumed 32% of the total DoD energy
The US Navy is responsible for a significant proportion of the US Department of Defense's (DoD) energy consumption. According to Dr. Karbuz, the Navy consumed 32% of the total DoD energy. While the exact quantitative value is challenging to determine, it is clear that the Navy's energy usage is substantial.
The Navy's high energy consumption is driven by its maritime dominance and the resulting need for a constant oil supply. This reliance on oil has strategic, geopolitical, and stability implications, especially in regions like the Middle East. As Zachary Petersen noted, the Navy must also plan for the future when oil may become prohibitively expensive or unavailable and consider alternate fuels to power its fleet and air forces.
To reduce their dependence on oil, the Navy has established Task Force Energy, with goals such as reducing non-tactical petroleum use and increasing the use of alternative energy sources. The Navy also hopes to demonstrate a Green Strike Group, fueled by biofuels and nuclear power, and has invested in renewable energy projects like the SolarStrong program. These initiatives aim to improve energy efficiency, reduce costs, and mitigate climate change.
The Navy's efforts to reduce oil dependency are critical for maintaining operational capabilities and ensuring the safe passage of commercial shipping. The development of a "Great Green Fleet," a carrier strike group using only alternative fuels or nuclear power, demonstrates the Navy's commitment to exploring mitigation techniques for its oil-guzzling engines. By improving energy efficiency and exploring alternative fuels, the Navy can reduce its environmental impact and maintain its maritime dominance in a sustainable manner.

The Navy's efforts to reduce oil dependency
The US Navy is the world's leading consumer of diesel fuel. As such, it must accelerate its alternative-energy efforts and reduce its dependence on oil.
One strategy to achieve this is to reduce energy use on Navy ships. A 2001 study concluded that fitting Navy cruisers with more energy-efficient electrical equipment could reduce fuel use by 10% to 25%. The Navy has already implemented this on many of its ships, along with fuel-saving bulbous bows and stern flaps. The Navy is also exploring the use of advanced turbine designs, such as intercooled recuperated (ICR) turbines, and integrated electric-drive propulsion, which can reduce fuel use by 10% to 25%.
Another strategy is to shift to alternative hydrocarbon fuels and increase reliance on nuclear propulsion. The Navy has expressed interest in using biodiesel, with the National Biodiesel Board awarding the Navy for its leadership in biodiesel use in 2005. The Navy has also set goals to produce at least 50% of shore-based energy from alternative sources by 2050 and acquire 50% of its total energy from alternative sources by 2020.
The Navy is also exploring the use of sail and solar power. The SolarStrong program has installed PV installations on 120,000 roofs of base housing across the US. Additionally, the Navy is investing in groundbreaking research that uses seawater to reduce dependency on oil and land. This involves engineering bacteria that grow in seawater to produce jet fuel intermediates that are chemically identical to petrochemical-derived molecules.
Through these initiatives, the Navy aims to reduce its oil dependency and improve operational capabilities, ensuring the safe passage of commercial shipping through sea lanes.

The US Navy's plan to produce jet fuel from seawater
The US Department of Defense is one of the largest single consumers of energy worldwide, with the US Navy responsible for 33% of its fuel consumption. To improve energy use in military operations, the Defense Department planned to invest $9 billion through 2017. The Navy also established Task Force Energy, which includes goals such as reducing non-tactical petroleum use in the commercial fleet by 50% by 2015 and having 50% of Navy and Marine Corps installations be net-zero by 2020.
In line with these goals, the US Navy has developed a process to produce jet fuel from seawater. This technology will help power fighter jets on aircraft carriers for longer periods before refueling from land is required. The process involves several steps:
- First, seawater is subjected to an ion exchange reaction to acidify it to a pH of 6.5 or below by exchanging H+ ions for Na+ ions.
- Once acidified, the seawater is degassed to obtain gaseous carbon dioxide.
- The carbon dioxide obtained is then fed to a reactor with hydrogen to produce hydrocarbons, such as jet fuels.
- The hydrogen used in the reactor can also be produced from seawater through an electrochemical device.
The resulting synthetic fuel is a hydrocarbon in the C9-C16 range, making it suitable as a renewable alternative to petroleum-based jet fuel. The fuel has been demonstrated to power a radio-controlled replica of a WWII P-51 Mustang, showcasing its viability.
However, there are challenges and considerations with this technology. One challenge is the amount of seawater needed to produce a substantial amount of fuel. It has been calculated that to make 100,000 gallons of fuel, nearly nine million cubic meters of water would need to be processed, assuming 100% efficiency. The process would also need to take place on a nuclear-powered aircraft carrier to ensure clean and cheap energy for the conversion. Additionally, the environmental impact of removing large volumes of seawater from the food chain and the release of carbon back into the atmosphere are factors to be addressed.

The DoD's Energy Conservation Investment Program (ECIP)
The United States Department of Defense (DoD) is one of the world's largest single consumers of energy, responsible for 93% of US government fuel consumption. The DoD established the Energy Conservation Investment Program (ECIP) to fund projects at military installations that are designed to conserve energy or water, generate electricity from renewable sources, promote energy security, or achieve a combination of these goals.
The ECIP is a subset of the Defense-Wide MilCon Program, specifically funding projects that improve energy resilience, contribute to mission assurance, save energy, and reduce the DoD's energy costs. This is achieved through the construction of new, highly efficient energy systems and technologies, or by modernizing existing energy systems. The American Recovery and Reinvestment Act of 2009 provided $120 million for the ECIP, allowing the Army, Navy, Marine Corps, and others to invest in energy efficiency.
The DoD collects information on how ECIP projects are expected to perform, including anticipated returns on investment and energy or water savings. Since the fiscal year 2011, the DoD has required services to measure and verify the extent to which ECIP projects have realized their projected savings and energy efficiencies. However, the DoD has not consistently reported this data, and managers of projects have often not measured or verified cost savings or reduced energy use.
To improve the program, the Government Accountability Office (GAO) has recommended that the DoD improve its reporting on anticipated ECIP savings, measure actual savings from ECIP projects, and review its goals and guidance to better align projects with the DoD's strategic vision. The DoD has concurred or partially concurred with these recommendations.
