Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

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. We distinguished ammonium carbamate pairs and a mix of ammonium carbamate and carbamic acid during carbon dioxide chemisorption.

Heliogen and Bloom Energy demonstrate production of low-cost green hydrogen; concentrated solar and high-temp electrolysis

Green Car Congress

Heliogen’s AI-enabled concentrated solar energy system is designed to create carbon-free steam, electricity, and heat from abundant and renewable sunlight. When combined with Bloom’s proprietary solid oxide, high-temperature electrolyzer, hydrogen can be produced 45% more efficiently than low-temperature PEM and alkaline electrolyzers.

GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

Green Car Congress

Stuart Licht have demonstrated the first facile high-yield, low-energy synthesis of macroscopic length carbon nanotubes (CNTs)—carbon nanotube wool—from CO 2 using molten carbonate electrolysis ( earlier post ). The process is constrained by the (low) cost of electricity. —Johnson et al.

PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

Methane derived from CO 2 and renewable H 2 sources is an attractive fuel, and it has great potential as a renewable hydrogen carrier as an environmentally responsible carbon capture and utilization approach. —Heldebrant et al. Different methods for converting CO 2 into methane have long been known.

Canadian startup launches INDIEGOGO funding campaign for low-cost electric self-charging solar tricycle produced in Pakistan

Green Car Congress

The team projects that the high-efficiency vehicle will have a a minimum unit cost of only $1,400 to produce—the price of an average mountain bike—once the funding goal is reached. The VEGAN is a lightweight multipurpose hybrid electric-self-charging solar tricycle. The team has not yet produced a working demo for their concept.

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.
