Brimos Durable Energy

Brimos Durable Energy explores , on a continuous basis , the applicability of systems that generate energy in a sustainable way . Since 2005 Brimos has followed the development of fuel cells from day to day .
Brimos believes that the market demands fuel cells initially from 0.5 to 10 kW , and then further developments towards 100 KW . There are two distinct markets :

Uninterrupted Power Supply

The uninterrupted power supply ( UPS ) : In the event of a power failure, the power will be maintained by capacitors ( super caps) for a few seconds so that the fuel cell can start up . This fuel cell is powered directly by hydrogen from cylinders. The residual is water vapour and heat . Up to now batteries are used . Beside the environmental unfriendliness and material usage ( metal ) , they will constantly be under load and will age after three to five years, the ability to generate power will decline such that they should be replaced. The fuel cell has no wear if it is not in use and can last many years , virtually with no maintenance.

Auxiliary Power Unit

The auxiliary power unit ( APU) : If somewhere electric current has to be  because locally there is no connection , a fuel cell can be used as an APU, with or without battery backup . If the fuel is to be supplied in the form of hydrogen , one encounters the problem that hydrogen is difficult to compress into a liquid and in practice has much volume in relation to the amount of energy that it carries. Roughly 12 bottles of 50 litres of hydrogen at a pressure of 200 bar , contain as much energy as is in a propane bottle of 10 litres under the same pressure. Therefore the choice is quickly made. LPG, LNG and diesel will be used for APU fuels. The organic types thereof may be used as well. Recently, reformation techniques are available for these purposes. Reforming means in this case that the fuels are separated into carbon and hydrogen molecules . The advantage of the use of a fuel cell in relation to an internal combustion engine is that the first makes no noise , and as exhaust gas it has water vapour and carbon dioxide, but no soot , NOx and noise . Since the energy efficiency is twice higher, there is up to 50 % saving on carbon dioxide.
