MINIPAK Personal Power Center
Horizon Fuel Cell Technologies
Horizon is combining its consumer fuel cell know-how with new fuel cartridge technologies to form a new portable power device named MINIPAK. The MINIPAK includes a passive air-breathing fuel cell, able to draw hydrogen stored as solid hydride inside the specially designed HYDROSTIK cartridge. This device is a universal portable power charger and power extender compatible with a variety of portable electronics. The MINIPAK is positioned to address gaps in providing energy "on the go" for power-hungry device users, as well to provide as a low cost energy storage option for emergencies and long duration off-grid power users.
Devices compatible with the MINIPAK include: cellphones, smartphones, GPS handhelds, and MP3 players, as well as all USB gadgets such as USB lighting devices, USB fans, USB speaker systems for MP3 players or smart-phones, and many more. The MINIPAK DC power output is up to 2W , delivered through a standard micro-USB port. Horizon also designed a compatible desktop hydrogen cartridge refueling system called "HYDROFILL" - which is available as a separate accessory. Although the standard HYDROFILL plugs into the grid, a small-scale solar or wind power solution is also another option for renewable hydrogen generation.
- Refillable hydrogen storage!
- Cheaper for the amount of storable energy ($/Wh)
- More available energy than most existing devices (Wh)
- "Hot swappable" energy - simply swap "empty for full" cartridges on the go
- Easy to use (Universal USB for multiple devices) - no need for adaptor plugs
- No need for wall sockets: ideal for remote "off-grid" use or international travel
- Eco-friendly - if disposed, canisters do not contain any mercury, cadmium or lead
- Multiple use - can be used for numerous portable devices, not just for cell-phones!
- No self discharge or memory effects - energy can be stored in a solid state for years
- Transportable on-board aircraft cabins - thanks to recent legislation approval on metal hydride devices
- Infrastructure for the future - HYDROFILL "home refueling station" can be used for many other fuel cell devices

The refillable solid-state hydrogen cartridge used in the MINIPAK is called HYDROSTIK. It has a battery-like form factor and contains a special metal alloy that allows hydrogen to be stored in a solid-state, as part of the metal alloy matrix inside the cartridge. In contrast with ordinary compressed hydrogen tanks, the pressure inside the canister is very low, making this device the safest and most practical means of storing hydrogen. The cartridge has been designed according to international standards (ISO 16111) for transportable gas storage devices (Hydrogen absorbed in reversible metal hydride).
The HYDROSTIK is not a one time use, disposable cartridge, and is thus more environmentally friendly. Unlike other fuel cartridges for fuel cells, it has the additional advantages of being refillable (from pressurized gas bottles, or from water-electrolysis based devices), non-toxic, fully recyclable, and competitive on energy storage cost with existing battery devices.
NOTE: 1 HYDROSTIK = 10 disposable AA batteries at 1W continuous power consumption. This is because at 1W power consumption, most AA batteries can last less than one hour, while a HYDROSTIK has enough energy to last 10 hours. Since one HYDROSTIK can be refilled 100 times, the same replaces (10x100) or 1000 disposable AA batteries over its lifetime. Each HYDROSTIK can store 11Wh of energy, which is enough for 1-2 charges of a 3G smartphone or 2-3 charges for the average cellphone. This is more than what present primary and rechargeable batteries are able to offer at the equivalent cost. HYDROSTIKs can be made available in bulk for refill using industrial gas, providing a low-cost portable energy option for users. When using industrial hydrogen gas, the overall energy efficiency of the MINIPAK is higher than batteries being recharged from the power grid (when counting power plant efficiency, power line losses, and typical AC/DC efficiency of chargers).
