Climate Change and Diesel Emissions

Altergy fuel cells have been certified by the California Air Resources Board to produce zero-emissions at the source and can help reduce your carbon footprint. Fuel cells produce electricity via a catalytic reaction between hydrogen, the most abundant gas in earth’s atmosphere, and the air we breathe. There is no combustion, no emissions, and the only byproduct is water.

Diesel generators face ongoing, frequently changing regulatory restrictions in an effort to decrease greenhouse gas emissions and address climate change. As diesel emission regulations have become increasingly restrictive, the cost of modifying generators to maintain compliance has risen significantly.

The EPA first regulated off-highway compression ignition diesel engines in 1996 and began enforcing limitations on exhaust emissions for stationary diesel generators in 2006. The regulations were introduced in steps known as Tier levels, and each tier specifies additional compliance requirements.

Furthermore, many state and local municipalities set even stricter emissions limits than those established by the EPA, which often results in additional equipment modification. Many “non-attainment” areas, particularly in and around dense or large population centers, set standards above and beyond EPA Tier 4 levels, which can inflate back-up power costs.
