A better way to keep that hydrogen tiger in your tank; algae biofuel begins to meet regular diesel standards; and China standardizes USB chargers for all cellphones.

Hydrogen Cars? Prototype Hydrogen Storage Tank Maintains Extended Thermal Endurance: Researchers at Lawrence Livermore National Laboratory have created an automobile hydrogen tank which can hold a liquid charge for up to six days without venting its contents. That’s a significant improvement of current designs. The problem with liquid hydrogen is that while it provides superior range over low pressure tanks, hydrogen must vent to relieve pressure as its container warms. Livermore scientists believe their new super-insulated tank might eventually hold a full chanrge for up to two weeks. (Science Daily)

Green Grow: Solazyme Claims Algae Biodiesel Meets Fuel Standards: California-based Solazyme Inc. says it has developed an algae-derived biodiesel that meets the American Society for Testing and Materials spec for diesel fuel. That means conventional diesel engines to could use the algae brew without modification. If Solazyme’s claims prove true, their algae biodiesel would be the first to meet ASTM standards. (WSJ.com)

Dye-Sensitized Solar Scores Morgan Stanley Backing: A British company has secured startup financing for a new king of ultra-flexible, inexpensive solar cell. G24 Innovations is working on cells made from dye-infused titanium dioxide. It’s a cheap, silicon-free design that works by a process similar to photosynthesis. G24 has a way to go before its technology can come to market, and the dye-sensitized cells remain about half as efficient as standard designs. The company hopes to develop new manufacturing processes at its new 23-acre facility. (Earth2Tech)

GM launches big incentives on hybrid SUVs: Boy, has GM got a deal for you! Those hulking gas hogs gathering dust on dealer lots? Take ‘em away at discounts up to $6 thousand! General Motors is also hoping to kick-start sluggish sales of its full-size hybrids with incentives of up to $4 thousand. The company recently announced its intention to shutter production lines and move away from the sale of large trucks and SUVs. (Autoblog Green)

Creating a Charging Standard for 500 Million Cell Phones: So how many chargers do you have around the house? Probably quite a few — and each charger is dedicated to a single device. On Friday, China will announce it has become the first country to implement a USB charger standard for its 600-million cellphone market. Some 3.2 billion power supplies for various electronic devices will produced in 2008 alone. By standardizing cellphone charger interfaces, China hopes to reduce the expense and solid waste generated by millions of discarded systems each year. (Businesswire)
