(Reuters) – Shell said on Monday it would acquire Danish biogas producer Nature Energy for nearly $2 billion, as it looks to boost its low-carbon business amid growing interest in biogas. Reuters had reported last month Shell was among a number of companies joining a second bidding round to acquire the Denmark-based company. Nature Energy, which operates 12 biogas plants in Denmark and one in France and has others in the pipeline, confirmed the deal in a separate statement.
