DURBAN - JSE-listed emerging natural gas and helium producer Renergen yesterday signed a supply agreement with Logico Logistics Group to supply liquefied natural gas (LNG) at Total filling stations along the N3 between Johannesburg and Durban. The signing of the supply agreement between the companies comes almost four months after Renergen and Total South Africa signed an agreement in June for the joint marketing and distribution of LNG through Total's service stations.
