hydrogen cost sustainable

  • Hydrogen Hydrogen can be produced domestically through electrolysis (the process of splitting the hydrogen and oxygen particles apart in a water molecule). When used in automobiles, a hydrogen-powered car will emit only water vapor from its tailpipe. Hydrogen vehicles use fuel cells as their source of power, and currently this technology is too expensive for most consumers. If the costs of fuel cell technology and hydrogen production can decrease, hydrogen may become one of the most environmentally friendly and sustainable sources of energy available.

  • he energy from the sun  varies from place to place and is very dependent on weather conditions. Without an atmosphere 1.4 KW/m2 per hour is available, but with an atmosphere we can only count on 1KW/m2 per hour in the absence of clouds. So, if asked how much 3 hours of sunlight on one square meter is worth what would you say?

  • Because solar electricity is so expensive, you would normally go to great lengths to reduce your electricity consumption. Instead of a desktop computer and a monitor you would use a laptop computer. You would use fluorescent lights instead of incandescent. You would use a small B&W TV instead of a large color set. You would get a small, extremely efficient refrigerator­. By doing these things you might be able to reduce your average power consumption to 100 watts. This would cut the size of your solar panel and its cost by a factor of 6, and this might bring it into the realm of possibility.
  • From our calculations and assumptions abo­ve, we know that a solar panel can generate 70 milliwatts per square inch * 5 hours = 350 milliwatt hours per day. Therefore you need about 41,000 square inches of solar panel for the house. That's a solar panel that measures about 285 square feet (about 26 square meters). That would cost around $16,000 right now. Then, because the sun only shines part of the time, you would need to purchase a battery bank, an inverter, etc., and that often doubles the cost of the installation.If you want to have a small room air conditioner in your bedroom, double everything.
  • A "typical home" in America can use either electricity or gas to provide heat -- heat for the house, the hot water, the clothes dryer and the stove/oven. If you were to power a house with solar electricity, you would certainly use gas appliances because solar electricity is so expensive. This means that what you would be powering with solar electricity are things like the refrigerator, the lights, the compute­r, the TV, stereo equipment, motors in things like furnace fans and the washer, etc. Let's say that all of those things average out to 600 watts on average. Over the course of 24 hours, you need 600 watts * 24 hours = 14,400 watt-hours per day.

  • The thing to remember, however, is that 100 watts per hour purchased from the power grid would only cost about 24 cents a day right now, or $91 a year. That's why you don't see many solar houses unless they are in very remote locations. When it only costs about $100 a year to purchase power from the grid, it is hard to justify spending thousands of dollars on a solar system.

  • Power density: Power from a solar array is limited by the size of the vehicle and area that can be exposed to sunlight. While energy can be accumulated in batteries to lower peak demand on the array and provide operation in sunless conditions, the battery adds weight and cost to the vehicle. The power limit can be mitigated by use of conventional electric cars supplied by solar (or other) power, recharging from the electrical grid.

  • Advantages by Application Telecoms CHP Fuel Cell Generators Electric Vehicles - APU's and Range Extenders Fuel Cell Forklifts Marine Power Portable Power
  • Low Emissions – Using hydrogen, PEM fuel cells only emit water at the point of use. Even when using hydrocarbon fuels, fuel cells emit considerably less emissions than other combustion based technologies, this is for two reasons. Firstly their higher efficiency means they require less fuel to generate the same energy and secondly because there is no combustion, there are negligible NOx or SOx emissions and no particulate emissions.
  • Reliability & Maintenance – The only moving parts in fuel cells are involved with water, heat and air management (pumps, blowers, compressors). When compared to internal combustion engines, there are considerably less moving parts and these require less maintenance (no oil changes every 150 hours). Less maintenance means less site visits or trips to the garage and reduced operating costs. Fuel cells can be monitored remotely and any problems dealt with quickly.

  • Few moving parts means all you will ever hear of a fuel cell is either a compressor, blower or pump
  • Hydrogen is the lightest of all gases and disperses very quickly, it is also non-polluting and hazardous to the surrounding environment (unlike gasoline a spillage / leak will not cause an environmental disaster). Hydrogen, like natural gas and petrol, is a fuel and will burn when ignited. Hydrogen is only explosive when it is able to build up in a enclosed space, which is very difficult as it has a habit of escaping (hydrogen is the smallest of all elements). As long as appropriate safety procedures are followed, as they should with any fuel, hydrogen is a safe fuel.

    Advantages & Benefits of Hydrogen and Fuel Cell Technologies High Efficiency - Like generators and other engines, fuel cells are energy conversion devices - they convert stored energy within a fuel into usable energy. A fuel cell uses an electrochemical reaction to extract energy directly in the form of heat and electricity, both of which can be utilised at the point of generation.

  • By the time it reaches Earth's surface, the energy in sunlight has fallen to about 1,000 watts per square meter at noon on a cloudless day. Averaged over the entire surface of the planet, 24 hours per day for a year, each square meter collects the approximate energy equivalent of almost a barrel of oil each year, or 4.2 kilowatt-hours of energy every day. Deserts, with very dry air and little cloud cover, receive the most sun—more than six kilowatt-hours per day per square meter. Northern climates, such as Boston, get closer to 3.6 kilowatt-hours. Sunlight varies by season as well, with some areas receiving very little sunshine in the winter. Seattle in December, for example, gets only about 0.7 kilowatt-hours per day. It should also be noted that these figures represent the maximum available solar energy that can be captured and used, but solar collectors capture only a portion of this, depending on their efficiency. For example, a one square meter solar electric panel with an efficiency of 15 percent would produce about one kilowatt-hour of electricity per day in Arizona.

  • lexible thin film cells and modules are created on the same production line by depositing the photoactive layer and other necessary layers on a flexible substrate. If the substrate is an insulator (e.g. polyester or polyimide film) then monolithic integration can be used. If it is a conductor then another technique for electrical connection must be used. The cells are assembled into modules by laminating them to a transparent colourless fluoropolymer on the front side (typically ETFE or FEP) and a polymer suitable for bonding to the final substrate on the other side. The only commercially available (in MW quantities) flexible module uses amorphous silicon triple junction (from Unisolar). So-called inverted metamorphic (IMM) multijunction solar cells made on compound-semiconductor technology are just becoming commercialized in July 2008. The University of Michigan's solar car that won the North American Solar Challenge in July 2008 used IMM thin-film flexible solar cells. The requirements for residential and commercial are different in that the residential needs are simple and can be packaged so that as solar cell technology progresses, the other base line equipment such as the battery, inverter and voltage sensing transfer switch still need to be compacted and unitized for residential use. Commercial use, depending on the size of the service will be limited in the photovoltaic cell arena, and more complex parabolic reflectors and solar concentrators are becoming the dominant technology. The global flexible and thin-film photovoltaic (PV) market, despite caution in the overall PV industry, is expected to experience a CAGR of over 35% to 2019, surpassing 32 GW according to a major new study by IntertechPira.[4]

  • The most important advantage of using liquid as fuel is that they can be easily pumped and can also be handled easily.
  • Biofuels are the best way of reducing the emission of the greenhouse gases.
  • Some of the major producers and users of biogases are Asia, Europe and America. Theoretically, biofuel can be easily produced through any carbon source; making the photosynthetic plants the most commonly used material for production. Almost all types of materials derived from the plants are used for manufacturing biogas. One of the greatest problems that is being faced by the researchers in the field is how to covert the biomass energy into the liquid fuel

  • The term “biofuels” encompasses a wide range of fuels, including vegetable oils, animal fats, ethanol, biodiesel (any oil or fat that undergoes transesterification to more closely resemble mineral-based fuel), and synfuel (fuel made from gasified organic matter, then liquefied to form fuel). The main common trait of all these fuels is that they are derived from organic biomass, rather than minerals.

    A fuel cell produces electricity directly from the reaction of hydrogen and oxygen. The only byproduct is water. A fuel-cell vehicle utilizes the electricity produced by the fuel cell to power motors at the vehicle's wheels. Fuel-cell vehicles are similar to battery-electric vehicles in that they are powered by electricity, but they do not have to be recharged like battery vehicles.

  • There have been studies that prove the many benefits of substituting fossil fuels (petroleum, etc) with biofuels such as biodiesel and ethanol. In its simplest sense, such biofuels are biodegradable which means they are derived from organic materials. They are naturally renewable. It can create numerous jobs since our own farmers can practically make them domestically. Consequently, our reliance on foreign sources of fossil fuels will be significantly reduced. Moreover, these biofuels emit nontoxic and cleaner emissions in comparison to traditional fuels. These alternative fuels also do not promote global warming, since the carbon they emit is taken back to the environment.
