Arizona Tribune - American Power Group Provides Update on 2010 NYC Based Dual Fuel Stationary Prime Power Conversion

ALGONA, IA / ACCESS Newswire / June 9, 2025 / American Power Group Corporation ("APG") (Pink:APGI) the leading U.S. based dual fuel diesel engine conversion technology company today provides an update on a multi-unit diesel engine conversion performed in 2010 for Penn South, officially known as Mutual Redevelopment Houses, Inc., an affordable cooperative housing community located in the Chelsea neighborhood of Manhattan. The complex encompasses 2,820 units housing 5,000+ tenants in 15 buildings located in the Chelsea neighborhood of Manhattan in New York City. Penn South operates a co-generation power plant that provides electricity, heat from October through May, and air-cooling during the summer months. In 2010, APG converted several 1.2MW CAT diesel engines to run on our dual fuel solution, providing not only meaningful cost savings but significant well documented emission reduction benefits associated with running cleaner burning natural gas which are very important, especially in urban locations like lower Manhattan.

Ed Johnson, Penn South Plant Manager, commented, "APG's two primary power dual fuel generators have been operating reliably at an average 50% displacement since their installation back in 2010. It is gratifying to know we have lowered our energy costs while also reducing harmful emissions for over the past 15 years of operation."

Chuck Coppa, APG's CEO/CFO stated, "We are very pleased to report how successful one of our earliest dual fuel stationary conversion projects has been, especially where the converted units are providing primary power over an extended period of time making reliability a critical factor. These results are in addition to those announced on May 12, 2025, detailing the fact our stationary/off-road dual fuel installation base in the oil/gas sector has reached an estimated 25 million cumulative run hour milestone."

Mr. Coppa added, "Having just recently attended an AI Energy Conference which focused on utilizing abundant and cleaner burning domestic natural gas to power the large data centers of the future, we see significant opportunities for our dual fuel conversion technology in large, prime power applications. With many electrical grids running either at capacity or in need of significant upgrades, the proven reliability and ease of operation of our cost-effective dual fuel solution in prime power applications is immediately available to meet those power demands.

APG's S4000 Dual Fuel Technology seamlessly introduces natural gas from renewable, fossil, or treated field gas into the induction system of a diesel engine, displacing up to 65% of the diesel fuel. The S4000 system does not change any of the OEM diesel engine components, maintaining base engine temperature and pressure parameters of the OEM engine. APG's software-based Dual Fuel solution safely allows peak diesel displacement of up to 65% with typical average displacement of around 50% without any expensive additional pre-combustion or spark arresting hardware protection required at higher displacement rates.

Generator power ratings from 100kW to 12MW have been successfully converted to APG's dual fuel solution on a wide array of OEM diesel engine platforms including:

*Caterpillar *Cummins *MTU *Detroit Diesel *MAN B&W

*Kohler *Perkins *John Deere *Komatsu *Wartsila

*Isuzu *Nigata *Isuzu *Daihtsu
