Is hydrogen a green energy solution?
As technology works to deliver clean solutions to satisfy our growing need for energy, there’s a lot of buzz about which is best. Anthropocene offers up this great explainer on the options. And a reader asks Dot whether hydrogen is as green as some are suggesting:

Because you’re right, Elaine. There has been plenty of chatter about hydrogen as a clean energy source. But is it? Really?
Dot took your question to the brainiacs at the Massachusetts Institute of Technology (MIT), where Dr. Ruaridh Macdonald, the Energy Systems Research Lead at the MIT Energy Initiative, was delighted to share his research about how to decarbonize the electricity grid while ensuring grid resilience and security.
Hydrogen can be a “clean” energy source, he told me, although that “can” is doing some heavy lifting. …
What does Dot mean? Read on.
