OFF-GRID POWER FOR CRITICAL INFRASTRUCTURE: U.S. AND CANADA O&G OPPORTUNITIES 01 ANY FUEL Uses Methanol Fuel cells will use industrial-grade methanol already available at the site 10x less greenhouse gas emitted vs. traditional combustion generators • Zero nitrogen oxides, sulfur oxides and particulate emissions 02 ANYWHERE Rugged and Reliable Unlike renewables, fuel cells work in almost any climate, geography and weather condition Designed to meet critical power requirements without interruption Does not fail in extreme conditions, can operate at low temperatures down to at least -40°C Fuel Cells can deliver power to well sites 24/7/365 ADVENT 03 GOAL: METHANE EMISSIONS TO ZERO Reduce O&G well site methane emissions (up to 40 Mt CO₂e per year) ● Fuel cells powering 185,000 oil and gas wellheads in Canada and the U.S. will reduce methane emissions (up to 40 million tons of CO₂e per year), which is equivalent to the carbon footprint of more than 8 million passenger cars The implementation of the solution can contribute to rapid decarbonization of the Oil & Gas industry by mitigating the methane emissions problem.
