It’s been a while since I bothered to bash hydrogen for transportation or cleantech special purpose acquisition corporations (SPAC), but the intersection of the two just crossed my screen. I’m talking about Hyzon, the SPAC-funded US-based manufacturer of heavy vehicles. Let’s start with SPACs and cleantech. These “blank check” companies … [continued]
Recently I sat down virtually with professional chemical process engineer Paul Martin of Spitfire Research on my podcast Redefining Energy – Tech to discuss how much industrial heat can be replaced with electrical heat technologies (tl’dr: virtually all of it directly). In the theme of providing transcripts of presentations I’m … [continued]
A couple of years ago, BF Nagy contacted me, asking if I would be interested in contributing to a book he was assembling. He already had Bill McKibben, Mark Z. Jacobson and others signed up, so how could I disagree? Fast forward two years, and the book, Proven Climate Solutions: … [continued]
Under the auspices of the India Smart Grid Forum, the think tank founded as an umbrella organization over India’s 28 state utilities to provide thought leadership, share leading practices, and bring international insights to India, I’m delivering bi-weekly webinars framed by the Short List of Climate Actions That Will Work. With the … [continued]
You might be surprised to know that the oil, gas, and coal industries make claims that aren’t completely aligned with reality, and indeed often make claims that have no discernible relationship to it. I know, I know, it’s a shocking revelation. That’s why Canadian firms in the sector are leading … [continued]
Cement is the gray glue that holds our economy together. It’s ubiquitous, if often hidden behind paint or plaster. It holds together the rock, sand, and steel that keep our buildings upright, our bridges spanning chasms, and our dams holding water for irrigation, generation, and recreation. And it’s a carbon … [continued]
A recent online discussion on gravity storage brought the usual suspects out of the woodwork. Proponents of heavy fluid pumped hydro reared their sludgy heads this time. Follow along for why this is a silly idea, as all gravity storage options that aren’t pushing water uphill turn out to be. … [continued]

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]
Regular readers will either appreciate or hate that for roughly 20 months I’ve been decorating my articles and presentations with images generated by artificial intelligence algorithms. I’m not going to address the full range of reasons, but will just do some basic math on the electricity use to get a … [continued]
