Extreme heat: What can be done to stop this “silent killer”?

While extreme heat is one of the planet’s clearest signals of global warming—last year was the world’s second hottest since 1880—it remains an invisible threat: a “silent killer” lurking in relatively clear view.

The ACWA Power–Air Products joint venture for green hydrogen: A new Saudi energy policy?

By Jean-François Seznec and Samer Mosis

In early July 2020, the city of Neom and ACWA Power of Saudi Arabia signed a joint venture agreement with Air Products of the United States to build the largest green hydrogen and green ammonia plant in the world. As the energy transition gains speed, this announcement is a significant step forward in establishing a new role for Middle Eastern oil-exporting countries in a future global economy less dependent on hydrocarbons. That said, the scale and relative inexperience of key project partners means the project still faces an uphill battle.

Searching for the missing link: Options for firm zero-carbon power

By Stephen S. Greene

“Firm” zero-carbon generation resources, which are not necessarily intended to run all the time, but can be available at any time, will be needed to complement renewable resources in the future, without emitting the CO2 produced by today’s fossil energy system. These resources might include, for example, fossil-fuel power plants with carbon capture, nuclear power plants with improved dispatchability, geothermal power, and bio-fueled generators. But the path to developing, and certainly deploying, such resources has been slower and more fraught than for renewables; these “firm” electricity generation resources represent a missing link in the path towards a decarbonized electricity grid.
