Biomethane will play a key role in Naturgy's strategic plans until the end of the decade, the Spanish gas company's executive chairman, Francisco Reynés, said on Tuesday.

"Renewable gases are our major bet and we are advancing biomethane contracts in our development portfolio," he told analysts after the company released its first-half results.

"We will have more visibility on this soon."

Although he declined to give specific figures, Reynes said the 2025-2030 strategic plan the company is working on will include biomethane prominently.
