Fuel cells are devices that are capable of converting chemical energy acquired through a certain type of fuel into usable electricity. The most common type of fuel used in this process is hydrogen. Hydrogen fuel cells are not a new technology, as some would suggest. The technology first appeare...
Raw/fresh water is sometimes used as a coolant for generators, but these are mostly limited to specific situations like small generators in city applications or very large units over 2250 kW and above. Hydrogen is sometimes used as a coolant for the stator windings of large generator units sinc...
With technology moving fast, hydrogen could come on par with electricity as a vital energy carrier. An energy carrier transmits energy to the customer in a ready to use form. Somerenewable energy sourcessuch as wind and sun may not be able to generate energy around the clock, but are able...
Like BEVs, FCEVs generate no greenhouse gas emissions when running. The only thing their tailpipes emit is water vapour. When FCEVs use “green hydrogen” – hydrogen produced by splitting water molecules using electricity from clean sources – they further reduce emissions, because the production...
How does a fuel cell make electricity from hydrogen? What happens in a fuel cell is called an electrochemical reaction. It's a chemical reaction, because it involves two chemicals joining together, but it's an electrical reaction too because electricity is produced as the reaction runs its ...
the exhibition floors and lecture theatres, the prospects of fully-electric transport are being considered and displayed. But among the myriad questions that all of these speeches and showcases raise, one is unavoidable: how are we going to cleanly and efficiently generate all of this el...
How the Hydrogen Economy Works How Electricity Works How Electromagnets Work How Electric Motors Work How Gas Turbine Engines Work How Floods Work What are amps, watts, volts and ohms? Is it possible to generate electricity directly from heat? Could I power my computer or my TV with a bicycle...

such as wind and solar. This could work by using the excess renewable energy (when generation is high and/or demand is low) to drive hydrogen production via electrolysis of water. The hydrogen can then be stored as compressed gas and put into a fuel cell to generate electricity when needed...
While in conventional power systems, the market value may converge to zero, this study demonstrates that "green" hydrogen production, through adding electricity demand in low-price hours, can effectively and permanently halt the decline. With an analytical derivation, a Monte Carlo simulation, and ...
