Environment

Excelerate Energy changed the LNG industry with the development of our Excelerate Energy Bridge® floating storage and regasification technology, which increased the availability of natural gas to markets around the world that previously had little or no access to this clean-burning fuel source.

Our solutions not only enable communities to take advantage of the environmental benefits of natural gas, but we operate the newest and most environmentally friendly fleet of LNG vessels in the world. Our solutions also eliminate the need to construct large on-shore storage facilities that can require hundreds of acres of land for siting.

Minimal Environmental Footprint

Having operations around the world, we are always sensitive to the local environment in which we operate, to minimize our environmental footprint and reduce potential impacts to the surrounding marine environment.

Our vessels can operate in both an open- or closed-loop regasification process, depending on the environmental sensitivities of the area. For example, Excelerate Energy’s Gulf Gateway® Deepwater Port utilized an open-loop regasification process that used the warm waters of the Gulf of Mexico in the vaporization process and had little impact on the surrounding marine environment, which thrives in warm waters. For our Northeast Gateway® Deepwater Port, we opted for a closed-loop regasification process, due to the highly sensitive marine environment and cooler waters of Massachusetts Bay. Seawater is not used in this vaporization process; therefore, the potential impact on the surrounding marine environment is reduced.

Continued Commitment

Through innovation and cooperation, at Excelerate Energy we constantly seek to improve the efficiency of our technology, not only to enhance its commercial capabilities, but also to protect the environment.

During the development of Northeast Gateway, our company recognized the opportunity to incorporate even more effective environmental controls into the design of the second-generation Energy Bridge floating storage and regasification units (FSRUs) that would call on the port, located approximately 13 miles east of Boston, Massachusetts. We have installed state-of-the-art selective catalytic reduction equipment on our new EBRVs, effectively reducing nitrogen oxide emissions from the vessel by more than 90%.

To further protect the environment, we have developed an operational process that reduces the normal shipboard water use during the regasification process by nearly 98%, reduces regasification fuel consumption by 10%, and reduces fuel consumption by 16%. A key component of achieving this reduction was the development of the heat recovery system, which was incorporated into the engine cooling system of the FSRUs. Like the selective catalytic reduction systems, the heat recovery system is installed on each of Excelerate Energy’s new vessels and retrofitted onto its existing fleet.
