Using an inexpensive polymer called melamine, researchers from UC Berkeley, Texas A&M and Stanford have created a cheap, easy and energy-efficient way to capture carbon dioxide from smokestacks. The low cost of porous melamine means that the material could be deployed widely.

Nevertheless, because of the scarcity and cost of Pt, a more abundant alternative is needed for cost-effective implementation. Molly is dirt cheap and abundant. The most common example of this is platinum (Pt), which has served as the benchmark catalyst for HER due to its high catalytic efficiency. —Stan Chou.

Currently, renewable hydrogen may be produced from water by electrolysis with either low efficiency alkaline electrolyzers that suffer 50–65% losses, or by more efficient acidic electrolyzers using expensive rare platinum group metal catalysts (Pt). Our new HER catalyst, Ni 5 P 4 , has the strong potential to overcome this challenge.

So imagine a million electric cars on US roads which all need to change these batteries in say 2015. Furthermore, changing the battery pack on say a Toyota Prius often costs a fortune, at least in most European countries, so such cars better be VERY cheap, but they’re not.

In 2015–expanded to emissions from residential, commercial, and other industrial combustion, and transportation fuels. In 2015–nearly 90% of emissions. Factors Determining Abatement Costs. The marginal costs of reducing (or abating) emissions depend on technological, behavioral, and policy-related factors.
