To help the world transition to net zero, decommissioned oil and gas platforms can be repurposed into green energy hubs.
This includes offshore rigs for carbon capture and storage or storing and transporting hydrogen, a type of sustainable fuel that doesn’t emit carbon when it is burned. A report published on the World Economic Forum suggested using legacy oil platforms to produce green hydrogen, which is generated using renewable energy.
Scientists have said that resusing depleted oil and gas wells would allow operators to access geothermal heat in hot rock formations, eliminating upfront costs of drilling new wells and potentially making the technology more appealing to the industry.
Moreover, researchers have suggested that repurposing depleted oil and gas wells may significantly help mitigate potential environmental impacts of abandoned wells and allow operators to access geothermal heat in underground rock formations. It also provides new job opportunities in areas with rich energy industry traditions.
According to Arash Dahi Taleghani, professor of petroleum and natural gas engineering at Penn State, using existing wells can help maintain employment in the area while also allowing communities to be part of the energy future.
