Peak-shaving fuel cell power

In addition to the mobile applications described above, other applications such as planes, ships, and robots will become important in the future. Especially when used as a replacement for batteries, longer operating times can be achieved with a fuel-cell system. Fuel-ceU hybrid systems are even an option for peak power shaving in the case of renewable energy such as solar or wind power. 

PEM fuel cells must be able to run continually or continuously as generators of premium power for base, backup, and peak-shaving loads in cooperation with the electric grid. 

Conventional uses of methanol account for 90% of present consumption and include formaldehyde, dimethyl terephthalate, methyl methacrylate, methyl halides, methylamines and various solvent and other applications. Newer uses for methanol that have revitalized its growth and outlook include a new technology for acetic acid, single cell protein, methyl tertiary butyl ether-(MTBE), and water denitrification. Potential uses for methanol include its use as a carrier for coal in pipelines, as a source of hydrogen or synthesis gas used in direct reduction of iron ore, as a direct additive to or a feedstock for gasoline, peak power shaving and other fuel related possibilities. Table II lists the world methanol demand by end use in 1979.
