Opening 10 new oil and gas sites is a win for fossil fuel companies – but a staggering loss for the rest of Australia

Ignoring the facts

The new sites for offshore gas and oil exploration comprise^[4] ten areas off the coasts of the NT, WA, Victoria, and the Ashmore and Cartier Islands. King’s announcement came at a resources conference in Darwin, where she said:

Gas enables greater use of renewables domestically by providing energy security. Australian [liquefied natural gas] is also a force for regional energy security and helps our trading partners meet their own decarbonisation goals.

The problem with this assessment is that it ignores two things.

First, Australia exports nearly 90% of domestically produced gas and lacks robust export controls^[5] to moderate this. Without these controls, increasing domestic production will not improve Australia’s energy security.

Second, gas can only enable greater use of renewables domestically and provide energy security where it is “decarbonised” through the use of carbon-capture and storage. If it isn’t decarbonised, using gas undermines energy security by risking further global warming.

However the deployment of CCS technology is complex, expensive and faces many barriers. To date it has a history of^[6] over-promising and under-delivering.

Carbon-capture and storage typically involves capturing carbon dioxide at the source (such as a coal-fired power station), sending it to a remote location and storing it underground.

Offshore CCS involves injecting and storing CO₂ in suitable rock formations. Doing so safely requires robust monitoring and verification, but challenging ocean conditions can make this extremely difficult.

For example, Chevron allegedly failed^[7] to capture and store CO₂ at its huge offshore Gorgon gas project, after the WA government approved the project on the condition the company sequester 80% of the project’s emissions in its first five years.

A report in February^[9] suggested the project emitted 16 million tonnes more than anticipated due to injection failure. King calls CCS a “proven^[10]” technology, but Chevron’s experience indicates this is far from the case.

King did say^[11] the federal government won’t rely entirely on CCS, adding “it’s one of the many means of getting to net-zero” and renewable energy remained central to Australia’s emissions reduction efforts.

But critics labelled^[12] the technology a “smokescreen” behind which fossil fuel companies can continue to pollute.

Fossil fuels are not the future

Putting gas in competition with renewable energy will end badly for the fossil fuel industry. As renewable energy’s market share expands, fossil fuels will become uneconomic^[13] due to their environmental impacts and higher costs.

Eventually, natural gas will be used only^[14] during periods of peak demand or when wind and solar are not producing electricity – in other words, when the sun isn’t shining and the wind isn’t blowing. It will not provide the steady, constant electricity supply that makes up our baseload power^[15] system. This reality will significantly reduce gas demand and negate the need for carbon-capture and storage.

Opening up new gas and oil exploration is a reactive and dangerous move that does not support Australia’s long-term energy future. Many of our international peers already acknowledge this.

The United Kingdom, for example, now generates 33%^[17] of its electricity from renewable sources such as onshore and offshore wind, solar and biomass. The subsequent decline of fossil fuels means the UK has reduced its greenhouse gas emissions by more than 50% on 1990 levels.

Gas in the UK^[18] is valuable for its ability to provide rapid, flexible power supply during peak periods, to integrate with other renewable technologies and to improve system flexibility. During periods of high demand, storage devices can discharge into the grid and maintain security of supply.

Wrong way, go back

Clearly, Australia is heading in the wrong direction by opening up new fossil fuel exploration.

The move will damage our longer-term security and undermine our climate imperatives. It ignores the glaring economic realities that will eventually push gas out of the market.

And opening new gas fields while carbon-capture remains uncertain is dangerous for the planet.
