Our Story

The ideas behind LEHR were born during a series of long cold nights spent in the North Sea converting gasoline engines to run on propane while aboard the research vessel the Sea Surveyor. Having already used propane to power small engines on several other ships in his years at sea, Captain Bernardo Herzer, CEO and founder of LEHR, knew he had something. “Propane is just safer, more efficient and more reliable,” said Captain Herzer, “that’s why we used it on our ships.” Years later, LEHR is now a groundbreaking leader in the research and development of environmentally friendly technologies.

Propane, the clean, green alternative fuel.


Propane is a three-carbon alkane with the molecular formula C 3H 8, normally a gas, but compressible to a transportable liquid. A by-product of natural gas processing and petroleum refining, Propane is one of a group of liquefied petroleum gases (LPG).


The EPA and CARB set strict new standards for gasoline marine engines and especially fuel systems in order to reduce the amount of gas fumes, carbon monoxide, hydrocarbons and smog-forming pollutants.


Through the use of propane fuel, LEHR has found a cost effective way to reduce emissions and associated health risks which will improve the marine environment all over the world.
