REPAIR teams will develop natural gas transmission pipeline retrofitting technology to rehabilitate existing cast iron
The US Department of Energy (DOE) announced $33 million in funding for 10 projects as part of the Advanced Research Projects Agency-Energy’s (ARPA-E) Rapid Encapsulation of Pipelines Avoiding Intensive Replacement (REPAIR) program. REPAIR teams will develop natural gas transmission pipeline retrofitting technology to rehabilitate existing cast iron and bare steel pipes by creating new, robust pipes inside of old ones.
“Enhancing America’s energy infrastructure, particularly for our abundant, reliable and affordable natural gas, is one of the highest priorities of this Administration,” said Under Secretary of Energy Mark W. Menezes. “The United States is now the world’s largest producer of oil and natural gas, and natural gas exports have quadrupled since President Trump took office. In order to keep up with this growing industry, it is imperative we modernize and build out infrastructure to safely and efficiently bring this product to market.
“Natural gas is a crucial energy source for 75 million American households and businesses,” said ARPA-E Director Lane Genatowski. “REPAIR teams will develop technology that enables gas utilities to update their distribution systems at low cost and continue to reliably service commercial and residential gas delivery needs nationwide.”
The selected REPAIR teams are developing smart coatings, robotic systems to line the inside of pipes, inspection tools to verify the integrity of the pipes, and mapping tools to enable 3D renderings of pipes and adjacent underground infrastructure. Technologies developed through these projects are working to extend the life of rehabilitated pipes by a minimum of 50 years and ensuring they have sufficient material properties to operate without reliance on the exterior pipe, all while meeting utility and regulatory requirements for use in natural gas distribution pipes.
Legacy pipes are still in use today and make up roughly 3% of distribution pipes in use. These legacy pipes account for a disproportionate number of leaks compared to modern infrastructure. REPAIR teams are developing technologies to address deficiencies while also working toward a 10-to-20-times reduction in cost per mile.
