Forever Chemicals No More? PFAS Are Destroyed With New Technique
New York TimesJUL 2022
Hydrogen-powered trains are the future of railway transportation. They provide a zero-emissions option for travel, can be deployed anywhere, and existing infrastructure can be retrofitted for hydrogen use. These new fleets also have economic benefits because they are cost-effective and require little maintenance. This is groundbreaking work.
At first glance, hydrogen trains appear to be a huge step forward to sustainable travel but they may not be the answer we're looking for: not all industries are able to convert to hydrogen, and, more importantly, not all hydrogen is carbon-free. With most hydrogen used coming from fossil fuel emissions, the true carbon-cost is concealed in the manufacturing process.
