Hydrogen Fuel - India's move towards energy security

Indian Oil Corporation is going to open a hydrogen fuel dispensing station in New Delhi, India. First of its kind in the country. This is planned as a start of new era in new year i.e. 2009 January.

The hydrogen fuel to be dispensed at this pump will use atmospheric air to synthesize pure hydrogen, which will be used to fuel vehicles. The process is called "electroliser" technology, which is the fuel cell technology.

As a by-product the vehicles using this technology will emit only water, while the CNG and Petrol/Diesel based vehicles emit harmful gasses.

Initially this dispenser will supply the mix of hydrogen and CNG roughly in ratio of 20:80. It will cost Rs 50 million (Rs 5 crore) to set up this dispenser. Many Car manufacturers will be involved in this experiment to test their hydrogen powered vehicles. To start with General Motors will test 'Equinox' and later on joined by more manufacturers.

It is in interest of whole world that country like India can resort to Hydrogen Fuel. This will not only lessen the burden from fossil fuel but also promote greener air. And hope so that the prices of crude oil can be controlled. I know that i am being too optimistic, but we have only hope to live on untill we have greener air!!

Fuel Cell

Fuel Cell technology is the one which is used to power the electric devices. For example vehicles developed with this technology gives the benefit of electric vehicles such as low emissions and cleaner running while it gives the running performance and easy refueling, the benefits of conventional engine vehicles.

Fuel Cell is a power source that generates electricity from the chemical reaction of hydrogen and oxygen. The hydrogen is fuel and the oxygen is the oxidant. There are several fuels from which hydrogen can be used, the most common is the Methanol.

Electricity produced from fuel cell uses less fuel than competing technologies and emit no pollution when used. The quality of electricity produced is very high and the operation is very quiet.
Fuel cell can power any device that requires energy like mobile phone, automobile, computer, houses, portable electrical equipment, etc.

There is a difference between a battery and fuel cell, i.e. whilst a battery chemically stores and releases electricity, a fuel cell produces energy by reacting a fuel with air. A battery will therefore run out of power and have to be recharged or disposed of. A fuel cell, however, will continue to function and produce power as long as the fuel and oxygen are supplied to it.

Fuel cell are not considered as a source of renewable energy. Fuel cells themselves are not a power source: rather they use a fuel to produce power. If this fuel is obtained from renewable sources, then fuel cells can be an important part of the energy chain, perhaps with hydrogen being used to store intermittent energy and fuel cells converting this hydrogen back to power when required.

The cost of fuel cell is high due to low commercialization but in due course of time as the volumes pick up then the price is certainly going to go south.

There are many organizations working in development of fuel cells like Yamaha motors is developing the Fuel Cell Motorcycle, MTI MicroFuel Cells announced a new fuel cell charger called Mobion, that will give you up to 25 hours of power for recharging cell phones, etc.

liquid cooling

Now a days we are interested in faster processing and hence faster CPUs, and as the speed of CPU is increasing, more transistors are required and hence more power is drawn. This is in-turn increasing the heat being generated from CPUs. To reduce this heat being dissipated into environment and faster cooling of CPU, there is new technology called as liquid cooling. More can be found out for the same at below link.

Liquid Cooling

Many organizations are working into this direction of using heat sinks via liquid cooling technology. This will increase the energy efficiencies, result in a a reduced carbon footprint and lead to environmental sustainability.

Alcatel-Lucent is having technology fair where such technologies will be showcased.
below is the link where more can be read about the product on display.

Save Energy, Save Money

need more tips on saving energy?
Google is trying every bit of it to pitch in the cause.

some tips from them:

Calculate your savings on energy

just an eyewasher.
below is a link where one can retrospect how much can be saved on energy. The savings will be from efficient usage of power and some common sense. There are no sacrifices to be made but one has to be bit rational in his/her activities.

Floating Wind Turbines

While our oceans house an eco-system, they also house a massive store of WIND ENERGY for us. The sea is becoming the prime real estate for generating renewable energy. Wind Turbines can be placed in sea where the large amount of alternate energy can be tapped. This energy will be cheaper and eco-friendly, as usual.

North Sea is first place where this is being carried out. Each turbine can be generating 5 MW energy to power atleast 3000 homes.

The technology used is deep water technology, where the system holds a 200 meter tall steel tube with an attached turbine and three 60-meter-long blade. The tube is 50-70 meter deep in water, rest above sea level. The turbine is tied to sea bed to keep it in place. Being far from sea shore there is less disturbance and disruptions, hence generating more power than surface turbines. Also the WIND is stronger at the mid of sea.

Google is promoting research to generate Energy from beneath...

The energy from the heat beneath the earth's surface is essentially an unlimited resource. What if it could be developed to help solve our energy challenges and fight global warming? Enhanced Geothermal Systems, or EGS, attempts to do just that. EGS produces heat and electricity by harnessing the energy from hot rock deep below the earth's surface, expanding the potential of traditional geothermal energy by orders of magnitude. EGS is a big challenge, but with the potential to power the world many times over, it demands our immediate attention.
