Clean Planet Ltd, located in Japan, currently develops energy technologies that looks quite unique when looking at the LENR technology landscape.
Their current technology makes use of a Hydrogen membrane that consist of a stack of very thin metal layers through which Hydrogen gas is passed, generating significant amount of heat.
The mechanism, as claimed, is absorbing and releasing hydrogen. An indication of this principle can be found in this patent application (Google translated).
The central unit that generates heat is quite simple, a vessel that is divided into two segments separated by the membrane allowing to slowly pass Hydrogen.
The heat is generated within the membrane.
The multi-layer (metal) membrane:
Provided are a novel heat utilization system and a heat generating device employing an inexpensive, clean, and safe thermal energy source. A heat utilization system 10 is provided with: a heat generating body 14 which generates heat by absorbing and releasing hydrogen; a hermetically sealed container 15 having a first chamber 21 and a second chamber 22 which are partitioned by means of the heat generating body 14; and a temperature regulating unit 16 for regulating the temperature of the heat generating body 14. The first chamber 21 and the second chamber 22 have different hydrogen pressures. The heat generating body 14 includes: supporting body formed using at least any of a porous material, a hydrogen permeable membrane, and a proton conductor; and a multilayer film provided on the supporting body. The multilayer film includes: a first layer which is formed using a hydrogen absorbing metal or a hydrogen absorbing alloy, and which has a thickness of less than 1000 nm; and a second layer which is formed using a hydrogen absorbing metal, a hydrogen absorbing alloy, or a ceramic, different from the first layer, and which has a thickness of less than 1000 nm.
