Core Competencies

If America is to become more prosperous and secure, green energy—and smart ways to create, distribute, and use it—will play a leading role. But engineering a green future comes with costs, risks, and choices that can be bewildering, even for a large agency. The Addx Energy Services team is steered by nuclear and system engineers. For decades, they successfully evaluated, designed, and maintained energy and power systems for the Navy. So whether you’re considering fossil fuel, nuclear energy, renewables, or fuel cells, Addx can help.

Past Performance

Development and Manufacture of Small Nuclear Power Plants

Working with Galvin Electricity Initiative, Addx led an effort to explore whether it would be feasible for small, nuclear-powered generating systems to be built, distributed to areas underserved by large nuclear- or fossil-fueled power plants, and installed quickly at a competitive cost. Addx helped establish Galvin Energy, LLC, as a viable volume manufacturer and supporter of small, nuclear-powered generating systems that could be operated safely and installed almost anywhere in the world.

Energy Information Administration (EIA), Department of Energy

Addx energy analysts performed energy research studies, analyses, and estimations for three of EIA’s four program offices. They studied the nature and composition of U.S. and international energy sources and reserves; proposed methods and formulas for modeling various theories about energy production and demand; and researched cases where estimates or models had done a poor job of predicting the demand or cost for a specific kind of energy production
