The title of this post, is the same as that as this article on the Australian Broadcasting Corporation.
This is the first paragraph.
A new player has emerged in the developing field of zero-emissions steel making, promising to deliver commercial quantities of green steel by 2025 without using hydrogen.
It sounds too good to be true.
But.
- The process uses electricity, which of course can be renewable.
- The process comes from research at Massachusetts Institute of Technology (MIT).
- The process doesn’t use hydrogen, coal or even a blast furnace.
- Electricity is used to turn iron ore into liquified metal.
- It is based on a technique called Molten Oxide Electrolysis (MOE), which is used in aluminium refining.
A American startup called Boston Metal is developing the technology.
If it can be made to work, it is truly game-changing technology.
Any area in the world, with large amounts of renewable energy, (Think Scunthorpe and Teesside) can transform their steelmaking to zero-carbon in a few years.

The title of this post, is the same as that of this article on The Times.
This is the first paragraph.
Bill Gates has invested in a carbon capture start-up. His Breakthrough Energy Ventures fund has taken part in an $80 million fundraising for Verdox, a Massachusetts-based business whose technology aims to remove carbon dioxide directly from the air.
I have my doubts that this technology will ever be economic, especially as plant, trees and in particular rain forests, do a good job at using the carbon dioxide. Planting trees is also one of those feel-good community activities.
This last paragraph gives a few details of the process.
Verdox, which is a spinout from the Massachusetts Institute of Technology, claims that its system is cheaper and more efficient. It uses a special plastic, which when charged with electricity, can extract CO2 from a mixture of gases. A change in voltage releases the CO2.
It is a process with a good pedigree, but you’ve still got to find a way to store or use the carbon dioxide.
Plants worked out how to do that eons ago.
