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.
