Radical New Gas Alternative That Your Kids Will be Using

By Darshan Goswami, M.S., P.E.

Hydrogen, produced from tap water, could become the forever fuel of the future, generating power for homes, industry, and cars.

A new day is dawning for a revolutionary way to generate electric power from renewable energy sources. Imagine a future where the electrical power needed to run your computer, TV and DVD is generated from a small appliance about the size of a dishwasher located in your home. Envision generating electricity without combustion, and producing heat and pure drinking water as by-products.

Picture a world powered almost entirely by an infinitely abundant and totally clean fuel. Hydrogen, the most common element in the universe, is that fuel, which can be produced from tap water to generate power for homes and cars.

Imagine being able to drive your car more than 500 miles between fill-ups. The car you drive could become a “power station on wheels” producing about 30 to 50 kilowatts of electricity. At work the parked car in the parking lot could be making money for you by supplying energy to the power grid during peak hours. The same fuel cells in the car parked in your garage could provide power for your home use.

In the new age of hydrogen, each individual could become the producer as well as the consumer of energy. Automobile, oil, and utility companies are spending billions to make this dream come true.

Renewable Energy Source

Hydrogen is “a renewable, versatile, simple sustainable domestic energy” and there is no danger of running out of hydrogen because it is the most abundant element in the universe. Hydrogen can be produced through a thermal, electrolytic, or photolytic process from fossil fuels, biomass, or water. Renewable and nuclear systems can produce hydrogen from water using a thermal or electrolytic process. People can even produce it in their homes with relatively simple apparatus.

The Hydrogen Economy is the term used to mark the shift from fossil fuels such as coal, oil, and gas to hydrogen. The vision of a Hydrogen Economy is one of an unlimited source of fuel that would be used to generate energy without releasing carbon and other pollutants into the air.

Hydrogen has the potential to do for the energy revolution what the computer and the Internet have done for the information revolution. Fuel cells are considered the “microchip of the hydrogen age,” the key to abundant energy from secure, renewable resources. Ultimately, fuel cells supplying homes, businesses, and industries could be linked to a national power grid allowing surplus power at one location to be transferred to areas experiencing power shortages.

Hydrocarbon Economy

Today, we have a “hydrocarbon economy” but the transition toward a “Hydrogen Economy” has already begun. In the very near future we will have weaned ourselves from carbon and we will live in a “Hydrogen Economy” powered by hydrogen energy from renewable resources. You will have access to hydrogen energy to the same extent that they now have access to petroleum, natural gas, and electric power.

Some cities, such as Chicago and Vancouver, already have buses powered by hydrogen fuel cells. Ford, GM, BMW, Toyota, and Honda have prototype cars powered by hydrogen. Ford chairman William Clay Ford Jr. has declared that the fuel cell will “finally end the 100-year reign of the internal-combustion engine.” Such efforts are leading the world toward the “Hydrogen Economy.”

The present fossil fuel economy has created significant environmental problems worldwide. The Hydrogen Economy promises to eliminate all of the problems created by the fossil fuel economy. The advantages of the Hydrogen Economy include greater fuel efficiency, elimination of pollution caused by fossil fuels, elimination of greenhouse gases, and elimination of economic dependence on Middle East oil reserves.

Good for Developing Countries

Specifically, the Hydrogen Economy may be even more beneficial to developing countries because it will generate more economic opportunities, reduce poverty and offer a dramatically cleaner renewable resource to bypass at least part of the expense of building a fossil fuel infrastructure.

The Hydrogen Economy could produce total decentralization of the global energy market controlled by giant oil companies and utilities, and result in vast redistribution of wealth and power. In a Hydrogen Economy utility companies will become obsolete.

The Hydrogen Economic revolution must overcome major challenges in regard to the safe production, storage and transportation of hydrogen, and in developing new sensor technology.

“World Hydrogen Energy Roadmap” must be developed to address hydrogen production, delivery and transportation, storage, conversion, public-private partnerships, research, codes and standards, testing, public education, and end use products. This effort must include government, industry, universities, and research laboratories.

Government subsidies and tax incentives could be used to encourage put the Hydrogen Economy on a fast track. The goal of the program should be to develop technologies to safely produce, store and transport hydrogen from water, nature’s abundant and virtually free source of hydrogen.

New Energy Revolution

Hydrogen has the potential to do for the energy revolution what the computer and the Internet have done for the information revolution. Global reliance on Middle East oil will come to an end and international trade balances will be realigned. Fuel cells are a “critical technology” that will bring a total revolution in the energy sector and change the course of history. President Bush has referred to fuel cells as the “wave of the future” and called for a “focused effort to bring fuel cells to market.”

The ultimate goal is to use the renewable energy of the sun to split water into its basic components of oxygen and hydrogen.

The Hydrogen Economy would open the doors for fundamental changes in our economic, political, and social institutions, similar to the impact of steam power at the beginning of the “Industrial Age.” The giant oil companies are investing heavily in a hydrogen future to control the design, production, and sales of the devices that produce and consume hydrogen. Fuel companies like Shell, BP, and Texaco are forming hydrogen and fuel cell technology divisions.

The Hydrogen Economy is a bright vision for the future of energy that will revolutionize the world by reducing our reliance for oil from Middle Eastern countries. I envision hydrogen as the power generation fuel of the future that will wean the world away from oil, slow global warming, and lift billions out of poverty. If significant progress is desired, government and private partnerships must be established to concentrate development efforts. A “Manhattan Hydrogen Project” is needed to ensure the Hydrogen Economy vision becomes a reality soon.

Until recently, he was the Chief of Energy Forecasting and Renewable Energy at the Rural Development, U.S. Department of Agriculture (USDA) in Washington, DC. Earlier, he worked for 30 years at Duquesne Light, an electric utility company in Pittsburgh, PA.


There are many renewable energy source alternatives out there and plenty of technical innovations are cropping up, increasing our potential to replace our reliance on both oil and fossil fuels.

It wasn’t all that long ago that the idea of making a car that could run on, say, AIR, seemed completely preposterous. But guess what? It’s available. NOW!

The Air Car, by Moteur Developement Int. runs on compressed air technology.

According to a January article in the MIT publication Technology Review, the Air Car is set to go into commercial production as early as this summer, and MDI has struck a deal with India’s largest carmaker, Tata Motors, to put the non-polluting vehicles on the streets of India later this year.

We are simply running out of excuses for not converting to safer, renewable energy sources that don’t turn the Earth into a toxic waste dump with every light we turn on and every mile we drive.

Harnessing the energy of the sun is now also a very cost effective alternative for homes and other buildings. The award winning Nanosolar Company announced on their website that they shipped their first commercial order in December 2007. And since their breakthrough solar coating is produced at an 80 percent reduced cost from previous years, it should make them a serious contender for consumer dollars.

My new office building, constructed for my practice and web team, will have solar power, and it seems obvious to me that this technology will allow us to not only radically lower our utility bills, but do it without polluting our environment.

We have to stop this unnecessary reliance on oil and fossil fuels, and we’re starting to see some very viable, exciting options.
