Material property testing of several different pipeline steels in hydrogen at multiple pressures for the measure of fracture toughness. Four types of steels were tested: St35 seamless circa 1930, X42 ERW circa 1961, X70 SAWH circa 1974, and L485 SAWH…
This research effort focused on identifying equipment and processes that can be applied at compressor and pump stations to improve station operating efficiency, thereby reducing greenhouse gas (GHG) emissions. The project approach included a…
There are many standards, recommended practices (RP) and guidelines available for subsea pipe-line integrity management (PIM). In all of these, inspection is a key part of managing the integrity of subsea pipelines. However, detailed coverage of…
This report examines a novel methodology for approximate prediction of the on-bottom kinematics in shallow waters and shore approach regions. The method involves simulation of generic shallow water scenarios in the Danish Hydraulic Institute MIKE…
The primary pipeline GHGs sources are facility methane fugitive and vented emissions. combustion CO2 from reciprocating engines and turbines, and reciprocating engine unburned methane from combustion. PRCI evaluation of federally reported data…
As a Strategic Research Priority (SRP), one of the key research objectives for PRCI and its members includes reducing Greenhouse Gas (GHG) from pipeline systems by developing, demonstrating, and validating processes and sensors to detect, quantify,…
The Jet Propulsion Laboratory (JPL) has developed a highly sensitive methane sensor called the Open Path Laser Spectrometer (OPLS) which detects methane to 10 ppb s-1 and weighs several hundred grams. This report describes the integration of OPLS…
With the rise of hydrogen use in the natural gas grid a need exists for reliable measurements of the amount of energy being transported and traded for hydrogen admixtures. Using VSL's high-pressure Gas Oil Piston Prover (GOPP) primary standard, the…
This project focused on the gathering, dissemination, and identification of critical variables affectng line pipe steels in hydrogen service. Published studies from US government labs (e.g., NIST, Sandia) and global publications were reviewed and…
Energy production from renewable energy sources is not stable and any fluctuations in energy production need to be eliminated with underground energy storage. Demand of underground gas storage will be increasing, due to the switching to green energy,…
