G2 Net-Zero Awards McDermott FEED Contract for a Zero Emissions NET Power Plant

G2 Net-Zero CEO Angele Davis today announced the award of a Front-End Engineering Design (FEED) contract for the development of its net-zero power generation plant in Southwest Louisiana to McDermott International.

"We executed an intensive and exhaustive search to find the right provider and all roads led to McDermott," said Davis. "Their proven project execution model, unparalleled expertise, industry-leading safety record and technical standards will help propel G2 toward profitable on-schedule production of our much-anticipated net-zero emission products. The world is telling us they want and need our products today-not 20 years from now-and we've promised to deliver. McDermott has a long record of providing exactly the skills, experience and innovation necessary to bring G2's vision to market."

G2 Net-Zero, a venture of Chas Roemer Innovations, is a Louisiana-based company that will use breakthrough technology developed by NET Power to provide emission-free electricity, liquefied natural gas and industrial by-products like blue ammonia, argon, nitrogen, hydrogen and oxygen to a world hungry for clean energy solutions.

"We welcome the opportunity to progress towards a carbon-neutral future driven by clean, sustainable and affordable energy with G2," said Samik Mukherjee, McDermott Executive Vice President and Chief Operating Officer. "This award is another example of our integrated approach, strategic resources and expertise with breakthrough technology to advance the energy transition and quickly deliver carbon-neutral products."

McDermott is a leading fully-integrated provider of technology and infrastructure to the global energy industry with more than 100 years of offshore and onshore experience in engineering, fabrication and construction capabilities that extend across the upstream and downstream energy value chain. Work will begin January 2022 and is expected to be completed in nine months.

"We are pleased to see G2 Net-Zero engaging the services of the much-respected McDermott to execute the project's FEED. McDermott's long history of tailored, fine-tuned project management assures G2's ability to expediently deploy our NET Power technology and get their suite of net-zero products swiftly out into a world eagerly waiting for clean energy options," said Ron DeGregorio, NET Power CEO.

Davis continued, "All three of our organizations are dedicated to applying their strategic talents, their industry expertise and American ingenuity in advancement of the energy evolution. We're excited to be working with companies headed by leadership who understand and support G2's vision."
