ICL team assesses relative costs of carbon mitigation for 12 H2 production paths; trade-off between cost and level of decarbonization

Green Car Congress

A team at Imperial College London has examined the relative costs of carbon mitigation from a lifecycle perspective for 12 different hydrogen production techniques using fossil fuels, nuclear energy and renewable sources. Their results show a trade-off between the cost of mitigation and the proportion of decarbonization achieved.

Novel bi-metallic palladium-tungsten nano-alloy an efficient low-cost fuel cell catalyst; simple microwave synthesis

Green Car Congress

The Pd-islands (light-brown spheres) are embedded in an environment of tungsten (blue spheres). The unique environment around the Pd-islands give rise to special effects that all together turn the islands into highly efficient catalytic hot-spots for oxygen reduction. A schematic model of the unique morphology of the alloy.

I write quite a bit about unmanned electric aircraft, and the benefits (both for people and the environment) that they come with as they replace the mission of many manned aircraft. Even more importantly, the low cost of operation gives more people access to aviation, even in a limited way, which saves money and saves […].
