Bioengineering algae to make hydrogen

The scientists say introducing an enzyme into the water in which the algae live suppresses sugar production and increases hydrogen production by about 400 percent without killing the organisms.

Ultimately, the bioengineered algae could be used to produce hydrogen on a large scale because algae is abundant, prolific and hardy and there is nothing toxic involved in the process.

Creating hydrogen on a renewable basis at mass scale could be used to power fuel cells, which create energy with no byproducts except water from hydrogen and oxygen.

Sustainable hydrogen fuel from spinach and sunlight

Researchers at the Oak Ridge National Laboratory in Tennessee have confirmed a system for converting visible light into hydrogen fuel based on an ordinary, off-the-shelf ingredient from the produce section of a local market: spinach.

Fuel cells run on hydrogen. Given a cheap reliable source of hydrogen, they could power cars, homes, offie buildings and much more – with zero emissions too.

Tonga using deep water buoys with wind turbines to produce hydrogen for power

hydrogen buoy

Maetec LLC on behalf of the tiny South Pacific islands of Tonga has created a deep water wind turbine and buoy combination for producing hydrogen through electrolysis of seawater. The hydrogen will then be piped underwater along the seabed to a power generation station where it will replace diesel fuel for producing electricity for the grid.

I-5 could be first alternative fuel highway in U.S.

better place battery exchange

The governors of California, Oregon, and Washington recently met to discuss having alt fuel the entire length of I-5. It would include biofuel, hydrogen, CNG, and facilities for swapping out EV batteries, which can be done in 5 minutes by Better Place stations for their cars.

The Better Place network will provide fully-automated battery exchange stations. These swap stations are designed to extend the driver’s journey beyond the 100 mile range of a fully-charged battery. Because most of today’s driving is within 40 miles of the home, a visit to one of these facilities will be infrequent when compared to the number of times we currently have to pull into a gas station.

Y’know, this is how change happen. Thinking big, then doing it. That’s why I find cleantech so inspiring, they aren’t letting trifles like a global financial meltdown get in the way of what they want to do.
