Natural gas answers greenhouse gas demands
Posted: 29 October 2006
Australian Pipeline Industry Association (APIA) Chief Executive, Ms Cheryl Cartwright believes policy makers should not ignore the benefits of natural gas to help reduce Australia’s contribution to greenhouse gas emissions.
Ms Cartwright said that, in spite of the accepted need to address climate change, the obvious benefits and availability of natural gas had, so far, been widely ignored.
A new report, commissioned by APIA, demonstrates that, while renewable energy generation is likely to be viable in the future and public acceptance of nuclear power remains doubtful, natural gas is the sensible alternative in the short to medium term.
“Gas is less expensive and more reliable than renewable energy sources and it is certainly more greenhouse-friendly than is coal. Even if industries move to geo-sequestration of fossil fuel emissions, natural gas remains generally less expensive than coal,” Ms Cartwright said.
The report says: “At a cost of around $50 per tonne of carbon dioxide equivalent injected, sequestering emissions would roughly double the cost of electrical power from new generation coal generators, and add about one third to the cost of electrical power generation from natural gas.”
The report concludes: “In managing the near term need for new energy, and if greenhouse gas minimisation is a priority, it will be necessary to rely on natural gas and renewable energies, as the currently available lowest emission technologies.
“With the abundant supply of natural gas, and proven technologies, this fuel can be introduced relatively quickly as an alternative energy source, while newer low-emission and sequestration technologies are developed for the longer-term reduction of greenhouse emissions from the stationary energy sector.”
Ms Cartwright said that, while the general public wants climate change addressed, the debate should move beyond nuclear, ‘clean coal’ and renewable energy and accept the benefits of natural gas.
“Renewables, ‘clean coal’ and nuclear energy sources may well meet some of Australia’s long-term needs but the current discussion ignores the fact that natural gas can make a major difference in the short to medium term; it can be the ‘transition’ fuel for Australia, while newer technologies are being further developed.
“Increased use of natural gas should be a key part of a greenhouse gas response, rather than simply focussing on the longer-term possibilities of renewable energies and unpopular solutions such as nuclear.”
The report, Meeting Increasing Energy demand and the Reduction of Greenhouse Emissions in the Stationary Energy Sector, was written by South Australian-based greenhouse and energy consultant, Mr Derek Sullens.
