Three companies – Air Fuel Synthesis, Cool Planet Energy Systems, and Joule Unlimited – are generating comment and controversy for their approaches to creating different kinds of biofuels. They all promise extreme reductions in carbon emissions and lower prices at the pump. Their output could use existing infrastructure for delivery, making them all desire able commodities if their promise can be achieved. Cool Planet  Cool Planet Energy Systems claims to be, “The only company producing carbon negative fuels using plant photosynthesis to remove CO2 from our atmosphere.” Its now patented approach recycles its solid products back into the soil, and using more of the liquid fuel products cleans the air more quickly, according to the firm’s web site. The company’s process divides its output from plant-based sources into liquid fuel and bio-char, an activated carbon that can be used as a coal substitute or fertilizer and soil conditioner, in which instance it acts as a carbon sequestration material, reducing the …

Better Batteries: 3x Life, 30-Percent Cost

The CAFE blog’s recent news about graphene electrode developments by Argonne National Laboratory in applications by Envia, a startup battery company in Newark, California, led to an almost immediate follow-up by another startup, California Lithium Battery (CalBattery), but with a different form factor in mind. The company’s purpose can be divined from their mission statement.  “Our mission is to become the leading United States-based developer and manufacturer of advanced, safe, high-performance Very large Format (VLF) lithium batteries for utility energy storage, EVs, and specialized industrial and military applications.”  These batteries would be used in transportation and stationary power markets in North America, Europe and Asia. Asked to define VLF batteries, founder and CEO Phil Roberts said that their transportation batteries would come in 40 Amp-hour prismatic packaging, and those for the stationary power market would range up to 400 Amp-hours.  This large format approach allows more active materials to be packed into a single package, increasing the total energy density …
