WHAT IS WATER-ENERGY NEXUS?
There is no formal definition for the water-energy nexus – the concept refers to the relationship between the water used for energy production,[1] including both electricity and sources of fuel such as oil and natural gas, and the energy consumed to extract, purify, deliver, heat/cool, treat and dispose of water (and wastewater) sometimes referred to as the energy intensity (EI). The relationship is not truly a closed loop as the water used for energy production need not be the same water that is processed using that energy, but all forms of energy production require some input of water making the relationship inextricable.
So... does that mean that Water Assisted Energy company and Hydrobike are conducting development of electrolysis which fits with the DOE's position on water-energy nexus? We think so. If we can produce energy efficiently to be used in cleaning and heating water for municipalities, and in doing so, create cleaner exhausts from using oxyhydrogen in engines, than the relationship between the energy used for water treatment becomes healthier for all of us, and cheaper for municipalities on several levels. They reduce their carbon footprint, while extending the life of motors and turn older motors into cleaner operating systems.
What is the DOE doing on that front now? Let's look.

AOI 1A: Energy-Water Nexus Implications and Opportunities of a Hydrogen Economy
Fossil Energy in the H2 Economy – A Carbon-Water-Energy Nexus Adaptive Evaluation Platform — Florida A&M University (Tallahassee, Florida) aims to support the efficient, environmentally sound integration of fossil fuels into the hydrogen economy as a complement to renewable energy resources penetration. The primary objectives of the proposed work are to: 1) survey and document the current technologies that enable the integration of fossil fuels into the hydrogen economy, including hydrogen production, transportation, storage and use, with an emphasis on tracking their potential for carbon neutrality, the intensity of water usage and strategies to mitigate the energy-water-CO2 nexus; and 2) to develop tools to assist the planning and decision making process at regional and national levels regarding the insertion and adoption of technologies for fossil energy-derived hydrogen with reference to their water intensity, life-cycle cost, greenhouse gases and energy efficiency.

The Department of Energy's Water-Energy Tech Team has prepared a new report -- The Water-Energy Nexus: Challenges and Opportunities -- that frames an integrated challenge and opportunity space around the water-energy nexus for the Department and its partners, laying the foundation for future efforts.
When severe drought affected more than a third of the United States in 2012, limited water availability constrained the operation of some power plants and other energy production activities. Hurricane Sandy demonstrated the compounding ramifications of vital water infrastructure losing power. The recent boom in domestic unconventional oil and gas development has added complexity to the national dialogue on the relationship between energy and water resources.
The Department is working with partners -- including other federal agencies, state and local governments, members of Congress, foreign governments, tribal governments, private industry, academic institutions, non-governmental organizations, and citizens -- to pursue research, development, and deployment of key technologies; sharing of robust datasets; integration of models to inform decision-making; harmonization of policies where warranted; and enhanced public dialogue.
The Green Hydrogen Electrolysis business is booming. And, it's only going to get bigger. We are very pleased to see this, as our development of the MicroCUBE technology is a fit in many verticals as water assisted energy using aqueous solution green hydrogen on-demand electrolysis can make a 'big bang' in this new world.
