The Blue Planet Foundation and the national office of the Sierra Club are opposing a plan by Hawaii Gas to begin shipping liquified natural gas to Hawaii.

Among the concerns expressed by the two groups in documents filed today with the Federal Energy Regulatory Commission is that bringing in LNG runs contrary to the state’s push to reduce its dependence on fossil fuel.

Hawaii Gas is seeking regulatory approval from FERC to ship LNG to Hawaii. The two groups filed motions with FERC to intervene in the case, which would allow them have more influence in the process than if they were simply observers.

Hawaii Gas officials have said the state could benefit from bringing in LNG, which is priced significantly below the oil that Hawaii relies on to satisfy the bulk of its energy needs.

Blue Planet said in its filing, among other things, that Hawaii Gas’ application is “deficient insofar as it seeks commission approval of a comprehensive LNG plan yet does not discuss all aspects of that plan in sufficient detail to allow the commission to approve such a plan at this time.”
