With the advent of Nano-catalysts and Viral Scaffolds the extraction of hydrogen has became much cheaper and more efficient. According to Gridshift, cheaper than gasoline. Surely a new appreciation for this resource will come about and new technologies utilising hydrogen should now be evaluated.
Fuel for Cars, Energy for Homes,
With the advent of nano-extraction techniques, the extraction of
hydrogen from sea water for the use of power generation and fueling
of cars is a step closer. NGEN's proposed conversion of coal and gas
fired power stations to hydrogen and the supply of hydrogen for cars
will revolutionise the worlds energy sector.
MIT's Belcher uses engineered virus to split water
By Christine Peterson, on April 16th, 2010
Angela Belcher and team at MIT have tweaked a bacterial virus to serve as a scaffolding to:
attract and bind with molecules of a catalyst (the team used iridium oxide) and a biological pigment (zinc porphyrins). The viruses became wire-like devices that could very efficiently split the oxygen from water molecules.
Belcher says that
within two years she expects to have a prototype device that can carry out the whole process of splitting water into oxygen and hydrogen, using a self-sustaining and durable system.
This is just a very early taste of what we can expect someday from more extensively designed molecular machine systems.
Hydrogen is a critical piece of Americas future renewable energy
policy, said Robert Dopp, CEO of GridShift, Inc. Our new water
electrolysis process generates carbon neutral hydrogen that is
than gasoline at a fraction of the cost and size of currently
available water electrolysis hydrogen generators. We are now on the
path to a truly viable hydrogen fueled future.
The key to GridShifts process is a new method for coating a complex
three-dimensionally shaped electrode on all surfaces with a unique
combination of nano catalysts that expose the catalysts to the
electrolyte for efficient water electrolysis reactions and is robust
enough to withstand the rigors of electrolysis. The result is an
electrolyzer running as a full cell at 1000 milliamp per cm2 at 80%
energy efficiency. GridShift is on track to reach their goal of 85%
energy efficiency, which is 47 kWh/kgH2 or $2.35 per kg of H2.
Technical details of the development, procedure and the discovery are
available in a whitepaper published at
Coal Conversion Techniques Coal to Gas to Hydrogen
As the breakdown of the climate talks in Copenhagen attest to, we must otherwise institute measures for the reduction of carbon pollution. The conversion of current coal fired infrastructure to gas and then further to hydrogen is of import to the reduction models otherwise explored. Conversion techniques and engineering practices will be used to implement change in the energy sector for the benefit of global achievement in the environmental action plans set before us all.
Further conversion to hydrogen, with the advent of nanoextraction of hydrogen from sea water, will be implemented to achieve further reductions in carbon pollution. The required conversion techniques and engineering will be invaluable for the rollout of conversion to go ahead. Current infrastructure must be converted or superseded to achieve any reductions, particularly as energy needs increase. The ability to provide expertise in conversion techniques or the engineering inherent in conversion is needed to allow the efficient changeover from coal to gas and so on. Firms specialising in these capabilities will reap many benefits from the greening economy, now and into the future.
