Matt has over 30 years of technical and managerial experience spanning from industry operations to construction management to environmental and air quality services. He brings expertise managing technical services for a variety of energy industry clients. He was responsible for teams that have provided air and GHG emissions inventory and protocol development, field research, regulatory compliance, and emission reduction strategies for public and private sector clients. 

A recent study conducted by Queen Mary University of London (QMUL) and implemented in the field by SLR has been published in the Environmental Science and Technology journal, a publication of the American Chemical Society (ACS). The peer reviewed publication, which included SLR as a co-author, is the first to directly measure methane and carbon dioxide emissions from liquefied natural gas (LNG) shipping. The study was funded by the Collaboratory to Advance Methane Science.  The SLR team that deployed to the ship was Aaron Wilson and Chris Johnson, along with our QMUL colleague. 

The team used two FTIR measurement systems, an optical gas imaging camera, and a high-volume sampler. Other key SLR team members included Kenny Malmquist and project manager Matt Harrison. “The most interesting find was that methane slip emissions were high from the small ship generators, rather than just from the large propulsion system”. “We anticipate measuring additional ships with different engine configurations and generator operating practices in the next year, and this will help our natural gas industry clients to understand and control emissions globally,” said Mr. Harrison. The SLR methane team, coordinated by Matt Harrison, continues to grow in size and has been on the leading edge of methane emissions research and policy efforts, including protocols for measurements and reductions.
