New Kind of Electroysis to Catalyze Hydrogen Economy

Yes, there's a double meaning to "catalyze" in that title. A couple of scientists at MIT have created a new kind of catalyst that makes electrolysis much simpler, cheaper and http://www.transitofvenus.org/viagra-without-prescription-online efficient. Theoretically this could help save the world by:

  1. Creating a simple way to produce hydrogen fuel for our automobile fleet
  2. Storing electricity provided by intermittent renewables like wind and solar
  3. Storing electricity during cheap off-peak times for use during peak hours
  4. Eliminating the cheap viagra overnight need for hydrogen transport, as it could be produced anywhere with connection to the electric grid

Probably the biggest deal here is number 2 and 3. We've already seen some steps toward a distributed power system where everyone has a fuel source in their house. Bloom Energy is hoping to create a system that would allow every person to viagra on line prescription have a hydrogen storage / electricity creation box in their home.

The new technique uses inexpensive catalysts containing cobalt and phosphate. But the biggest deal is that it bubbles 100% of the oxygen produced, meaning that they can close the loop and not have to discard any water to keep efficiency high.

Other electrolysis techniques don't remove all of the O2 from he water, creating hydroxides that degrade performance. The new system, developed at MIT, removes all of the oxygen, so that electrolysis can be efficient at room temperature without electrolyte inputs to remove the hydroxides.

The scientists seem to be confident that this is a game changer, and a breakthrough, though they're saying it'll be a decade before it can be fully implemented. Nonetheless, this is a big freakin' deal, especially if combined with the pfizer viagra cheap next wave of cheap renewables. Power storage remains a huge issue, and if this could solve that problem, it would be the second step we need toward a truly renewable future.

ITM Power Unveils Home Hydrogen Refuel Station


Last year we heard a little birdy say that hydrogen refueling could be something you can do in your garage with UK-based ITM Power’s home hydrogen refuling station. Well, a prototype for the home-based station has been unveiled.

The station can be used for fueling a hydrogen-powered car, as well as cooking, running the fridge, and heating, and could make hydrogen slightly more efficient since it won’t need to be transported to filling stations like Shell.

ITM's station uses an electrolyser to cialis 100 produce gas from water and electricity, which an internal combustion generator converts to electricity. The unit can only make enough gas overnight to get you 25 miles down the road, so you may have to save up a bit if you have a bit of purchase viagra online a commute during the day. And you have to be fairly well off in the first place, since the buy cialis uk cost for a unit is www.aco.ca expected to be around $4,000, plus installation costs, if the units are mass produced. Taking this into account along with the relatively lower efficiency rate of creating the hydrogen, it seems like it would take quite a long time to recoup the cost.

The company expects units to be available for sale around the end of the year, with buyers likely being large companies with a vehicle fleet. ITM is hoping the home-owner-as-customer potential comes in with Prime Minister Gordon Brown’s push to have all new cars sold in Britain to how much cialis by hybrid or electric by 2020 – apparently because fuel cell cars are then an option for buyers. I have a feeling people would rather get an EV or Prius than an expensive and inefficient hydrogen-powered car and http://www.barefootfoundation.com/cialis-in-spain expensive home refueling station. Just my guess…

But the idea of using this as a way to power you home is intriguing. Not as much as solar windows and the like, but intriguing all the only today cheap viagra no prescription same.

Los Angeles Shell Station to Offer Hydrogen

 

For the (one or two) LA drivers of hydrogen-powered vehicles, there will be a filling station on Santa Monica Boulevard to accommodate you starting later in June, and several more LA-based stations in the next few months.

 

Creating the hydrogen with an electrolyzer from electricity on site, the station will be part of a research program run by US Department of Energy in conjunction with Shell and GM. Shell will build a few more stations on its own in the next few months, and they will be part of “mini networks” of hydrogen filling stations that will hopefully help spark mass production of tramadol no script overnight fuel cell vehicles. These are needed in big cities since the only emission would be water, but paradoxically, the source for the hydrogen is fossil fuels. For now, anyway.

 

Shell is making a big step forward in this process because it is working with electrolyzers running off wind power (in the Netherlands) and geothermal power (in Iceland), but these types of sources don’t create enough hydrogen to support the huge number of LA drivers who would be buying these some-day-mass-produced fuel cell vehicles. So, yet again, no silver bullet is in sight. Rather, a compromise is made. At least they recognize this is a short term solution. Other solutions in the works include carbon capture and storage, bio-feedstocks and municipal solid waste.

 

Hydrogen fueling stations are being tested in other parts of the world, and we'll be able watch these and Shell to see how to progress.

The UK's First Hydrogen Fueling Station Opens

Last week saw the opening of the first hydrogen fuelling station in England. The station is based at Birmingham University, where experiments are being carried out to test the viability of hydrogen in transport applications, as part of Birmingham’s ‘Science City’ hydrogen energy project.

Researchers will compare five hydrogen-powered vehicles with the university’s own fleet of petrol, diesel, and electric vehicles to it's cool woman and cialis learn more about efficiency and performance. The main aim is to work out exactly how the vehicles might need to be adapted to enable the only best offers get cialis in canada cost-effective use of www.roli-guggers.de hydrogen vehicles in the future.

The Series-100 station has been specially designed by Air-Products, a Pennsylvania-based hydrogen producer and price of levitra in canada supplier. The fueller is made up of an integrated compression, hydrogen storage, and dispensing system, optimised to fuel up to six vehicles per day. Crucially, the system is portable, making it a perfect choice for start-up stations.

Looking ahead, the research team hope that the results of the project will encourage greater government support, particularly of the financial kind, and help kick-start the wider application of a hydrogen-fuelling infrastructure across the UK.

Could Chemical Solar Power Beat Photovoltaics?

Could a vat of chemicals be a more effective way to harness the sun's energy than those fancy, intricately crafted silicon wafers? We're not sure, but Professor Chaurasia of uk propecia sales the University of Birmingham, UK, was telling me about that possibility earlier in the month.

He's developing a unique process in which propanol is buy viagra 50 mg dehydrogenated using a catalyst and clean, solar energy. The hydrogen then generates electricity - courtesy of a Proton Exchange Membrane fuel cell. The byproduct of dehydrogenated propanol -- acetone -- and the protons (H+) and electrons (e-) then all recombine to form more propanol, which is then ready to start the project all over again.

Very simply, it's a way of harnessing the instability of propanol to buy viagra from india push electrons onto the grid. It's not a new way of creating hydrogen, it's a new way of harnessing the sun's power using the www.bsz-wurzen.de versatility of hydrogen, and the instability of propanol. Indeed, it's pretty genius.

But the question of online levitra uk economics remains. Current solar cells are getting cheaper and more efficient every day. And though Chaurasia thinks that his chemical cells could be competitive, that will depend on several factors. The propanol is cheap, PEM fuel cells and titanium catalysts are not, so we will have to wait for these "solar fuel cells" to scale up before making any real judgments.

Chaurasia's most recent paper was published in the International Journal of Sustainble Energy.
