Marathon Digital has started mining Bitcoin using methane gas extracted from a landfill in Utah. The 280-kW off-grid pilot project is a collaboration between Marathon and Nodal Power, which raised $13 million in a seed round in August to operate two sites, one of which includes a data center.

Other Bitcoin miners, such as Genesis Digital Assets Limited, are also seeking new green generating solutions.

Argentine presidential candidate Sergio Massa has received criticism from the country's cryptocurrency community for a proposal to mine Bitcoin using excess natural gas from the Vaca Muerta oil fields. The proposal was presented by computer scientist Santiago Siri and would involve using surplus gas from Vaca Muerta, a major shale oil and gas deposit in western Argentina, to power bitcoin mining operations. While the project has its proponents, Bitcoin miners and advocates have expressed skepticism, arguing that BTC mining is too complex and competitive for the government to get involved. Critics suggest that private-public partnerships may be a better alternative model if the state wishes to participate.
