Bill Gates: To cut emissions, use this Swiss Army Knife [View all]

[Caribbeans]

Bill Gates | June 21, 2022

When most people picture greenhouse gas emissions, they think about cars and electricity. That’s because they turn keys, press buttons, and flip switches every day. The good news is, we already have ways to decarbonize these types of emissions (solar, wind, and nuclear power and lithium ion batteries). The bad news is, they add up to only about one third of the total.

The other two thirds—almost 35 billion tons—are much harder for most people to see. For example, we all use products made of cement, plastic, and steel, but most of us don’t manufacture them or load them onto cargo ships. To zero out emissions on these products, we need new technologies. Enter clean hydrogen. It has so many potential uses that some people refer to it as the Swiss Army Knife of decarbonization.

What hydrogen can do

The world already uses 70 million tons of hydrogen each year as a chemical in some manufacturing processes like making fertilizer. Today, nearly all that hydrogen is produced from fossil fuels. If we make that hydrogen clean, we eliminate the 1.6 percent of global emissions that it is responsible for now.

But that’s just the beginning. Hydrogen is pure, reactive chemical energy. If we can bring the cost down far enough and make enough of it, we can also start using clean hydrogen to replace fossil fuels in all sorts of other industrial processes, including important ones like making plastic and steel, liquid fuels, and even food. (It’s called the Swiss Army Knife for a reason.)...>>

With Gates and his money on Team Hydrogen now, expect even faster progress

US DOE releases notice of intent for Regional Clean Hydrogen Hub Program

Currently, DOE plans to award funds to six to ten H2Hub projects in different regions across the country. DOE expects the program to provide a minimum award range of $400 to $500 million and a maximum range of $1 to $1.25 billion with a 50 percent minimum non-federal cost share. H2Hub projects are expected to be carried out over the course of eight to twelve years...more
