Without initially setting out to, I've begun focusing my coverage on the "hard to clean" parts of the economy -- areas outside the power sector where we have no clear way to decarbonize with today's technology. 
The bad news is, they add up to a lot of emissions (even before including agriculture), as @SteveDavisUCI @KenCaldeira et. al pointed out in Science earlier this year: technologyreview.com/s/611498/we-st…
The good news, as I've been writing, is that there are some heavyweight researchers and startups hard at work on these hard problems, including @dsadoway & Boston Metal's efforts to clean up steel production: technologyreview.com/s/611961/this-…
Meanwhile, @pivotbio secured a $70 million infusion from @btenergy & others to bring to market a microbe plant treatment that could replace synthetic fertilizer: technologyreview.com/the-download/6…
And today, I wrote about the research effort by @YetMingChiang @venkvis to develop a better battery for electric planes: technologyreview.com/s/612351/top-b…
The other bad news is most of these project have a long way to go before they could transform deeply entrenched industries -- the other good news is I'll be writing more on this topic, so please send promising research efforts and startups my way (& not to @AkshatRathi 😁)
