Low cost plasma membrane reactor to efficiently convert ammonia to hydrogen
Using a plasma field between an iron tube and palladium foil tube, ammonia can be broken down to nitrogen and hydrogen, with the hydrogen pulled through the palladium foil efficiently, resulting in very high hydrogen gas purity separation. Process is low temperature and pressure as well, though the palladium foil probably isn't cheap. Effectively an ammonia fuel reformer for a hydrogen fuel cell, allowing storage of low pressure ammonia as fuel.

The fuel cell for home - Research News June 2014 - Topic 2
Different from Ene-farm rigs, this is an augmented home gas heater, using a reformer and a SOFC fuel cell stack to coproduce power and heat. Not a water heater rig though. Shame you can't chain rig the fuel cell stack with an adsorption cooler plus water heater/space heater.

New green technology for hydrogen production
Claims lower temperature hydrogen gas production via sorption bed enhanced methane reformer, which sucks in CO2 while reforming so the output gas stream is high purity hydrogen. I wonder how you get the CO2 back out of the sorbent to recycle it though...

2008-ECD-NHA-presentation.pdf (application/pdf Object)
Interesting use of recyclable hydroxides to reform biomass or coal/methane into hydrogen in one step at low temperatures with high hydrogen purity and no CO or CO2 production. Though if you want the CO or CO2, you can heat the resulting carbonate output (recaustication like at paper mills) to recover a relatively pure gas stream and recover the hydroxide for recycling back into the process inputs.

ClearFuels - Technology
Interesting steam reformer that takes clean biomass and converts directly to syngas for feeding a FT process, utilizing FT tail gas for indirect heating of the biomass. Claim low costs, might be could for an algae biomass feedstock.

The Gort Cloud - Electric Pie
Tokyo gas is pushing the all gas home (natural gas/methane being the primary and possibly sole input energy source), using either a traditional burner, and moving up to fuelcells, to provide electricity, home water heating and radiant heating, and possibly an integrated hydrogen reformer to provide a home source of hydrogen fuel for family vehicles. The claim is made that since the existing grid loses so much in transmission and has no storage capability, the natural gas distribution network is a better choice for primary energy delivery. Maybe, though I don't necessarily buy the transmission argument because the natural gas distribution network is difficult to scale due to less forgiving mass flow limits and construction costs, and wasn't originally designed for such an increase in home consumption. That, and natural gas prices are still rising and few countries are producing commercial volumes of renewable synthetic methane so the green argument is a little weak.
