In January 1972 the Val Verde (now Terrell) natural gas process plant started to capture carbon dioxide (CO2, or, short, “carbon”) and transport it in a pipeline to the Kelly Snyder oil field in West Texas. It was the first commercial use of CO2 for enhanced oil recovery (EOR). EOR had been slow in the making. The first patent for EOR was issued in 1952 and field test had been done in 1964, but in the last three decades EOR has become a well-established technology in the North American oil industry. Most of the CO2 comes from naturally occurring sources.
CO2 is the main anthropogenic (human induced) greenhouse gas (GHG), about 76 %. Consequently, it is the focus when addressing global warming.

In the last 10 years USA has reduced the carbon dioxide (CO2) by 13 % to the lowest annual level since 1992. During the same time China has become the world’s largest CO2 emitter by far, 28.2% of the global CO2 emissions (2016).
Lake Blåsjö, Norway.
Hydro storage is basically a renewable battery. Lake Blåsjö (“Blue Lake”) in Norway with a capacity of 7.8 terrawatthours (TWh) has become a symbol of Norway’s potential to become a “Blue Battery” for Northern Europe. To put the number in perspective 7.8 TWh would cover the electric consumption of over 750 000 residential homes. To accumulate the same amount of energy with lithium ion batteries it would take over 200 years of full production at Tesla’s planned Gigafactory.
Energy efficiency as well as the “dark green” renewable energy of wind and solar are the best sustainable options to reduce CO2. However, if urgent CO2 reduction is the focus, one must not lose sight of additional options.

Energy Secretary Ernest Moniz in November last year visited the new Kemper power plant in Mississippi. After touring the plant he said: “I consider seeing this plant a look at the future.” It was probably meant that Kemper will be the big bang for future coal fired power plants. However, massive cost overruns and project delays have added arguments to the critics saying that this is not a viable future.
