The world’s first ‘carbon-neutral’ cargo ship is already low on gas

Grist

When shipping giant Maersk announced last month it would operate a “carbon-neutral” vessel by 2023, the Danish company committed to using a fuel that’s made from renewable sources, is free of soot-forming pollutants — and is currently in scarce supply. E-methanol is made by combining hydrogen with carbon dioxide.

Carbon offsets alone won’t make flying climate-friendly

Grist

It’s packed with energy; per unit of weight, at least 60 times as much as the lithium-ion batteries used to propel electric cars. But according to a growing body of research, those efforts leave something out: Most of the planet-warming effects of flying aren’t from carbon dioxide. It’s also terrible for the climate. Others warm it.

Could trash-to-energy technology feed hydrogen demand?

GreenBiz

Early pioneers of these hydrogen-from-waste technologies such as Ways2H, SGH2 Energy (SGH2) and Standard Hydrogen say not only are they making carbon-free, energy-rich fuel, their approaches also will divert mountains of trash from landfills and waterways, cutting greenhouse gas emissions. . There are other ways to make hydrogen.

? Fueling carbon-free transport

Climate Tech VC

The Tank-up of Tomorrow Transportation accounts for ~16% of global GHG emissions , and while passenger vehicles have likely gone the way of EVs, cleaning up the remaining 55% of hard-to-decarbonize aviation, heavy ground transport, and maritime shipping is still—well, hard! Engines are optimized for fossil fuels.
