Study finds direct seawater splitting has substantial drawbacks to conventional water splitting, offers almost no advantage

Green Car Congress

A study by a team of researchers from Technische Universität Berlin (TUB) and Fritz-Haber-Institut der Max-Planck-Gesellschaft has found that direct seawater splitting for hydrogen production has substantial drawbacks compared to conventional water splitting and offers almost no advantage. Additionally, H 2 O is needed for water splitting.

Lux Research: cost of electrofuels remains far from viable

Green Car Congress

Production costs per barrel of oil equivalent. The cost of electrofuels—fuels produced by catalyst-based systems for light capture, water electrolysis, and catalytic conversion of carbon dioxide and hydrogen to liquid fuels—remains far away from viable, according to a new analysis by Lux Research.

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

Researchers at Harvard have demonstrated a metal-free organic–inorganic aqueous flow battery—a quinone–bromide flow battery (QBFB)—as an example of a class of energy storage materials that exploits the favorable chemical and electrochemical properties of a family of molecules known as quinones. —Huskinson et al.

Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

The new material is simple to make, requiring primarily off-the-shelf melamine powder—which today costs about $40 per ton—along with formaldehyde and cyanuric acid, a chemical that, among other uses, is added with chlorine to swimming pools. The low cost of porous melamine means that the material could be deployed widely.

Idaho National Lab and Bloom Energy produce hydrogen at record-setting efficiencies

Green Car Congress

Pairing the research and development capabilities of a national laboratory with innovative and forward-thinking organizations like Bloom Energy is how we make rapidly reducing the costs of clean hydrogen a reality and a real step toward changing the world’s energy future. —John Wagner, director, Idaho National Labs.

ExxonMobil, UC Berkeley, Berkeley Lab develop new MOF for carbon capture and steam regeneration

Green Car Congress

Laboratory tests indicate the patent-pending materials—tetraamine-functionalized metal organic frameworks—capture carbon dioxide emissions up to six times more effectively than conventional amine-based carbon capture technology. Sequestering the captured CO 2 underground costs an additional, though small, fraction of that.
