Energy major Shell is buying Europe’s largest renewable natural gas (RNG) — or biomethane — producer Nature Energy Biogas for nearly $2bn.

Dutch refining subsidiary Shell Petroleum said it has reached an agreement with Davidson Kempner Capital Management, Pioneer Point Partners and Sampension to acquire all the shares in Denmark-based Nature Energy.

The acquisition includes Nature Energy’s portfolio of cash-generative operating plants, associated feedstock supply and infrastructure, plus its pipeline of growth projects, Shell said.
