Clean Energy Solutions taps Viaspace as partner for Hawaii biogas project

In California, Clean Energy Solutions has retained VIASPACE as its agriculture feedstock resource and engineering expert for renewable energy projects being pursued in Hawaii.

In Hawaii, CES is working with Hawaii Gas, the state’s only franchised gas utility, to assess the use of the VIASPACE Giant King Grass to produce biogas. “Giant King Grass grows especially well in Hawaii and can produce some of the highest yields per acre of any energy crop,” said Viaspace in a prepared statement. “Perennial grasses like Giant King Grass also demonstrate favorable greenhouse gas system emissions, which reduces the net amount of carbon dioxide in the atmosphere.”

Biogas produced from Giant King Grass can be upgraded to pipeline quality methane, which is known as renewable natural gas (RNG). RNG can then be used directly by gas utility customers, by the electric utility or independent power producers for electricity generation and by the transportation industry for fleet or passenger vehicles.

Hawaii Gas is an indirect subsidiary of Macquarie Infrastructure Corporation, a $6.8 billion New York Stock Exchange listed corporation that owns, operates and invests in a portfolio of infrastructure businesses in the United States. Hawaii Gas supplies the island of Oahu with synthetic natural gas, and also provides propane to customers on the islands of Oahu, Kauai, Maui, Molokai, Lanai, and Hawaii.
