Electrolyzer stacks are manufactured, but hydrogen plants are built. Much of the apparent learning challenge—and most of the project cost—lives outside the stack factory.
Hydrogen cost forecasts often borrow one of the clean-energy transition’s most useful empirical tools: the experience curve. If a technology has historically fallen by a given percentage in cost every time cumulative deployment doubles, analysts can estimate how many doublings lie ahead and compound the learning rate into a future … [continued]
Steel decarbonization starts with demand, scrap, and electric arc furnaces, leaving new iron as the smaller residual problem.
Steel keeps getting framed as a hydrogen problem because hydrogen gives the sector a single shiny lever. Replace coal with hydrogen, keep making new iron, plug it into an electric arc furnace, and declare victory somewhere around the ribbon-cutting ceremony. It is an attractive story for governments, incumbent producers, electrolyzer … [continued]
In the first part of this series on XPENG, I focused on how the technology company treats and develops its employees. In the second part, the focus shifts to how Automation and AI make the most of their employees, as well as how this relates to existing expectations and expectations … [continued]
The Biden administration is deploying the Defense Production Act of 1950 to ensure that more US-manufactured heat pumps get into the market, more quickly.
Four years ago, things looked bleak for federal action in the industrial sector. Biden and Harris’ current plan is light on specific climate action for industry as well. The committed Kigali Amendment and Paris Accord ratifications will have flow-down impacts of course. There are research dollars for low-carbon concrete and … [continued]
ChatGPT & DALL-E generated panoramic image of a cement plant with a large vacuum cleaner labeled "CCS" hovering over it
As concrete month draws nearer to a close, it’s time to look at an option not previously explored, continuing to use limestone but bolting on carbon capture and paying for waste disposal in permanent sequestration sites. After fifteen years of assessing carbon capture technologies, pilots and proposals, this is one … [continued]
ChatGPT & DALL-E generated panoramic image of a bauxite refinery with a red mud pond and a cement plant beside it
One of the many people who have suggested I look at something in the space of cement and concrete decarbonization suggested red mud. All I knew was that it had something to do with aluminum, and hence I thought it would be another metal slag supplement to cement. You know … [continued]
The US offshore wind industry is finally getting a shot of adrenaline, from a gigantic new made-in-the-USA offshore services vessel. (Image courtesy of Ørsted via Twitter/X).
The US offshore wind industry is finally getting a shot of adrenaline from a gigantic new made-in-the-USA offshore services vessel.
CleanTechnica’s authors write often about their experiences with electric vehicles. They detail experiences as they go off with spouses, children, friends, and even dogs. I wish I could do that, but I don’t have an EV — or any car at all. In fact, I don’t even drive. So, I … [continued]
This new electric train will hit the rails in Australia, complete with a regenerative braking braking system that recharges its own battery on-the-go.
