Hydrogen is really an incredible energy source. Comes from water, and it’s waste is water.

There are many who criticize the making of it as not green enough, but if it is created at a dam, then the electricity generated to create the hydrogen is from a perfectly green source, and there is lots of water at the source.

It is the storage issue that hold this back from becoming the greenest, cheapest, perfectly renewable energy resource.

I’m still in “if it sounds too good to be true” mode with Cella and Voller.

The cost of getting the hydrogen has to addressed. Then we can see if their process is viable.

Yeah, need to wait for some third party testing (if they will allow it).

It looks like they’ll be presenting their research at the Fuel Cell and Hydrogen Energy conference:

Abstract #5190

Complex chemical hydrides now exist that store hydrogen in concentrations that are well above 10 wt%. For example, ammonia-borane is 19.6 wt% hydrogen, 12 wt% of which is released at temperatures below 150°C. However, these materials have slow desorption kinetics and many release other chemicals such as ammonia or borazine which would poison a fuel cell. Many are also difficult to handle in that they degrade rapidly in air. These issues can be solved using nanotechnology. We have developed a method using a process called electrospinning that can trap a complex chemical hydride inside a nano-porous polymer that speeds up the kinetics of hydrogen desorption, reduces the temperature at which the desorption occurs and filters out many if not all of the damaging chemicals. It also protects the hydrides from oxygen and water, making it possible to handle it in air. The coaxial electrospinning process that we use is simple and industrially scalable, it can be used to create 1-2 micron diameter fibers or small micron sized spheres of nano-porous polymers filled with the chemical hydride. We believe that this technology can produce a relatively inexpensive, compound material that be handled safely in air, operates at low pressures and temperatures and has sufficiently high hydrogen concentration and rapid desorption kinetics to be useful for transport applications.

It is interesting but I want to be sure he’s not a charlatan making money on new investors. Let’s see where this goes.

The problem with hydrogen is it’s too expensive energy wise to release the massive amount of energy within. Whoever solves that puzzle will get rich and the entire planet will benefit.

Unless have a fusion reactor, hydrogen is not an energy source. It takes energy to break a hydrogen atom from a water molecule - not coincidentally the same amount of energy that is released when it is burned. The energy has to come from somewhere else.

This invention, if it works, is basically a better battery. Hydrogen is attractive for this purpose because it burns clean but it’s a pain to store and transport. It would be great to solve those problems. It’s not free energy though.

re: #7 MinisterO

Yup. So many people get confused between an energy “source” and a “battery”.

re: #1 Buck

Hydrogen is really an incredible energy source.

Not on the Earth. On the Earth hydrogen is not found in the free state as an H molecule readily reacts with almost any other chemical. Thus, as MinisterO pointed out, one has to put energy into the freeing of H from whatever it has bound to in order to then use it to combine with something else.

Hydroelectricity is a possible source of the energy needed for the process, but why not just use the electricity directly for transportation? For air travel one will still want a chemical energy source, but for on the ground uses it might not make sense to use H but simply to build electric engines.
