A comprehensive proposal to simultaneously:

1) Create an entirely new and permanent economic frontier, initially with thousands of well-paying middle class jobs that cannot be outsourced or relocated, followed by millions more when it becomes fully operational.2) Transform the U.S. into the world's largest green energy exporter, potentially capable of meeting the lion's share of global current and future demand -without adding any greenhouse gases to the atmosphere.3) Transform the trade deficit into a surplus.4) Create a new drought-proof source of unpolluted water -unrelated to acquifers, rivers and lakes- to meet current and future demand.5) Begin the process to reverse global warming without harming any economy.BONUS: Public funds would not be required to build and operate it.A PrecedentIn 1998 Iceland announced its intention to eliminate its dependence on fossil fuels by creating a hydrogen energy economy. Endowed with abundant geothermal resources, the local price of electricity was lower than the price of the hydrocarbons that could be used to produce it. Accordingly, Iceland decided to export its surplus electricity by converting it into an exportable commodity, and in 2002 it produced 2,000 tons of hydrogen gas by electrolysis, primarily for the production of ammonia, at a local fertilizer plant. Due to reasons unrelated to the price of hydrogen, in 2004 the plant went out of business, and by 2006, deprived of its main customer, hydrogen production fell to negligible levels. However, these events proved that under certain conditions it is possible to produce hydrogen at prices below fossil fuels.PurposeThe purpose of this plan is to use solar energy to produce hydrogen and oxygen from the electrolysis of seawater (brine) in the U.S. for domestic use and export it to China and elsewhere to: (a) replace coal as its primary fuel to generate electricity; (b) produce pure water, and (c) eliminate the main culprit of air pollution. The system would be efficient and profitable.Hydrogen From Natural GasWith present knowhow more energy is required to produce hydrogen from water than can be obtained by oxidizing it. As a result, a self-sustaining chain reaction is not possible and an external source of energy, usually natural gas, is required. Since it is more efficient and less costly to use gas directly to make electricity, global hydrogen production from water electrolysis, which requires electricity itself, is currently negligible, about 4%.The Solar ExceptionFossil fuels and nuclear fission require extraordinarily costly and risky exploratory, mining, processing, and delivery operations. The incessant, ever-increasing burning of oil and coal has caused global warming and polluted the environment, and the need for a guaranteed supply of oil threatens to catalyze a cataclysmic war that will benefit no one and solve nothing. As for nuclear waste, its radioactive emissions last for hundreds of thousands of years, and current technology does not have a cost-effective way to stop them. In contrast, solar energy –the mainstay of most life on our planet- is delivered to us free, constantly, universally, and in great abundance.Free elemental hydrogen gas occurs naturally on Earth, but it is not widely accessible. Instead, most of it has combined with oxygen to form the oceans, lakes and rivers that cover three fourths of the surface of our planet. The process of producing elemental hydrogen from water using electricity is known as electrolysis. Due to its salt content, which is a natural electrocatalyst, seawater (brine) is about one million times more conductive than pure water, therefore it is far more energy-efficient to use brine to produce elemental hydrogen. One of the main obstacles to do so is that seawater and uninterrupted sunlight do not naturally coexist in high-yield locations -defined as exceedingly long coastlines naturally sheltered from precipitation such as hurricanes, cyclones, typhoons, snow, rain, quasi-permanent cloud cover or fog or sandstorms- safe from the incessant threat of all-out war. Consequently, it behooves us to find a way to combine the sun's energy, gravity and brine, which are free, abundant and virtually inexhaustible, to export hydrogen and freshwater at a lower cost overall to countries who would need to build enormously expensive irrigation projects and either fossil or nuclear plants to develop their arid regions. This article describes a way to do precisely that.Why produce hydrogen when the same solar energy could be used to produce electricity directly? Electricity cannot currently be easily exported from one non-contiguous landmass to another, and no country is currently exporting its surplus solar energy. A perfect example is the State of Hawaii; the islands cannot connect their grids, and its surplus solar energy is not being exported. Since an efficient, low-cost medium has not yet been discovered to do so, hydrogen -nature's battery- is the way to go. The first country that does it may well become the world’s largest and preferred energy supplier and the recipient of unimaginable wealth.Why should other countries want to buy American-produced hydrogen? Because only the U.S. could potentially export hydrogen a price below what others would have to pay for the sum of coal, gas or nuclear fuel; the hydrogen would allow buyers to generate electricity from a clean source and simultaneously manufacture water. Should hydrogen replace coal as the principal fuel to generate electricity, one of the largest sources of carbon dioxide and other pollutants would be eliminated; eventually the hydrogen might also be used for mobile applications. In addition, for countries that rely on nuclear power or have announced plans to increase their reliance on it such as France, Japan, and China, the ever-present danger of contamination due to natural catastrophes, terrorism or war would disappear.Storage And Transportation Of HydrogenHydrogen is corrosive; therefore, pipelines and storage tanks require expensive internal coatings. However, underground caverns, salt domes and depleted oil and gas fields, which do not corrode, are currently used to store hydrogen. Similar facilities could be dug near electric power plants at a relatively low cost. While initially expensive, the additional cost of coating the pipelines used to distribute it –which would be borne by the users- would be offset by low-cost raw materials, reliable supplies, and a cleaner environment.
