The carbon-free future should not be confused with a utopian future. A zero-carbon world will include the difficult realities experienced in Texas in February 2021.
As shown in a graph of US EIA data, during the recent extreme cold event in Texas, wind and solar could not hold flat compared with their baseline the week before (4–8 February). Coal and nuclear remained mostly steady, while natural-gas producers ramped up supplies delivered to power plants by a factor of 4, helping people who were struggling to heat their homes. Natural gas may not receive well-deserved recognition from some quarters, and blackouts and loss of life still occurred, but our industry stepped up when people needed us most. Texas generates 25% of the wind power in the US and has more solar potential than 18 northern states combined, yet wind and solar simply failed when called upon. As the world attempts to go carbon-free, this reviewer hopes that more consumers will see the difference between results and public-relations promises.
It will take a legitimate technological step-change before an unsubsidized renewable energy source is capable of replacing reliable fossil fuels. Imagine if Sir Isaac Newton, with all his brilliance, had tried to be the first man to land on the moon. In 1720, the cumulative knowledge did not exist to allow that to happen, and, if he had tried, he could have spent the entire British treasury and still failed. By standing upon the shoulders of giants like Newton, others were able to reach the moon 250 years later. Step-change technological breakthroughs happen when their time has come, not when mandated by political pressure.
Until you hear that commercial fusion reactors are online or that low-cost, grid-scale electricity storage made from commonplace materials can handle a 10-day cold snap or heat wave, there is no need to hang up your pipe wrenches. Fossil fuels will remain the most energy-dense, cost-effective, reliable energy source until an extraordinary breakthrough creates a better alternative.
The three papers selected for this feature demonstrate the continued critical role of gas production, and innovation therein, in the necessary daily role of supplying the world’s energy needs. One discusses means of exploiting stranded offshore gas reservoirs; the second details an Eagle Ford cyclic-gas-injection enhanced-oil-recovery effort; and the third focuses on the fracturing interference of multiwell pads in shale gas reservoirs.
