This process is less than 1% efficient at converting sunlight to stored chemical energy. Water will be the primary byproduct. A novel metal complex for electrolysis of water will be used to generate the hydrogen at high rates. per gallon. The project also will develop a chemical method to transform butanol into jet fuel.

Also on the list of five is the arrival of advanced batteries, including air batteries (e.g., Lithium air), but targeted initially at small devices. Batteries today have a number of problems, chiefly, the heavy metal-oxides used inside the battery greatly limit the amount of energy it can store, IBM notes. Earlier post.).

IBM and its partners have launched a multi-year research initiative exploring rechargeable Li-air systems: The Battery 500 Project. Only the aprotic configuration of a Li-air battery has shown any promise of electrical rechargeability; hence, this configuration is attracting the most effort to date, according to the authors.
