Environmentalists generally don’t get along with the natural gas industry.
Although it burns cleaner than coal, natural gas is still a fossil fuel – and the emissions from conventional gas power plants still contribute to global warming.
It’s simple science. Natural gas is made up of hydrocarbon molecules. When we burn gas to power steam turbines, those hydrocarbons react with the oxygen in the air. And that reaction produces greenhouse gases like carbon dioxide.
For decades, scientists have seen this as an unavoidable downside of gas power. But today, a consortium of small energy companies is building a new kind of gas power plant on the Texas coast. It uses a revolutionary technology called the Allam Cycle.
As you can see from this week’s chart, the Allam Cycle paves the way for something that sounds like an oxymoron – a zero-emissions gas power plant.
How the Allam Cycle Works
As we mentioned above, a conventional power plant burns natural gas to heat water and turns it into steam. That steam is then used to spin turbines and power a generator. The combustion produces carbon dioxide and other greenhouse gases as byproducts – and these are released into the atmosphere through smokestacks.
By contrast, the Allam Cycle doesn’t use steam to drive turbines. It uses carbon dioxide itself. This relatively inert gas can be recycled through the power plant again and again – no smokestack necessary.
In other words, the Allam Cycle is a zero-emissions technology that is much simpler (and cheaper) to use than fossil fuel alternatives like wind and solar power. And you don’t have to be a passionate environmentalist to see the investment appeal of this technology.

More Power From Less Gas
As this week’s chart shows, an Allam Cycle power plant isn’t just cleaner than a conventional combined-cycle plant. It’s also roughly 47% more efficient.
This is, once again, simple science. In a conventional power plant, hot steam and pollutant gases billow out of smokestacks all day. These emissions aren’t just dirty – they’re also a waste of heat energy. There’s no way to generate electricity from a cloud of smog in the sky.
But in an Allam Cycle power plant, these gases are looped back into the furnace. That means much less heat is wasted. And it means more electricity can be generated by the same quantity of fuel.
We understand that our readers have varying views on the severity of global warming. But no matter your opinion, the appeal of this technology should be clear. It’s paving the way for a more efficient energy system – and freeing up more American gas for export.
Alexander Green and his research team have been monitoring the development of the Allam Cycle closely – and they’ve found a way for ordinary investors to get a stake in this clean energy breakthrough. Click here to learn more.
