Compact Solar Unit Yields 250 Liters of Hydrogen per Day
The amount of energy needed to produce hydrogen, as well as the required materials has long been a challenge for renewable power researchers in order to make it scalable for [...]
Your Next Car Fuel: Water, Not Gas?
H2O in place of gas sounds pretty alluring. It also sounds pretty far out there. But given that we here at Cleantech Concepts have seen a lot of work on hydrogen production [...]
Solar Cell Generates Hydrogen and Electricity in Parallel
In the quest for abundant, renewable alternatives to fossil fuels, scientists have sought to harvest the sun’s energy through “water splitting,” an artificial [...]
Hydrogen from Renewables to Power Orkney Ferry
You could say that the Orkney islands are in a lucky location. The mainland coast and the islands themselves have a large surplus of renewable power, which European research [...]
Germany Debuts First Hydrogen Powered Train
The world’s first hydrogen fuel cell train rolled into the station last Sunday. The Coradia iLint train, built by Alstom in Salzgitter, Germany, is equipped with fuel cells [...]
Heavier Loads With Hydrogen Retrofits
It’s the clean technology dilemma. Do you go for a completely new and efficient design, or do you try for an inexpensive way of retrofitting existing infrastructure? Or [...]
Storing Solar Energy Through Photosynthesis
The idea of using renewable energy to make renewable fuel is the best of both worlds. A new, stable artificial photosynthesis device doubles the efficiency of harnessing [...]
New Catalyst May Slash Fuel Cell Cost
While fuel cells have the potential to power many different kinds of vehicles and devices, widespread use has been limited by a number of factors. Besides refueling [...]
