Research has shown that CO 2 can be converted to a variety of commodities, but because of the low energy state of CO 2 , the production costs would be prohibitive in many cases. However, they may be considered in order to establish a baseline for making comparisons with results from coal-derived flue gas.
Low-cost electricity is the single most important factor for the production of all zero carbon energies and globally, there are significant unused and non-commercial renewable resources which can be developed by the P2XFloater. The renewable source can be either hydro power, sun or wind- or a combination of these.

The photocatalytic water splitting opened up by titanium oxide (TiO 2 ) has attracted much attention because the energy of sunlight can be converted into clean gaseous fuel. By comparison, no gas was generated from pure water itself under the same irradiation conditions. The generated gas was collected from the full bottle.
Acetogens have several advantages to yeast: they convert all xylose (C 5 ) and glucose (C 6 ) sugars and tolerate all breakdown products of biomass; they operate in harsh environments; and they produce no CO 2 as a by-product. In comparison, traditional yeast fermentation creates one molecule of CO 2 for every molecule of ethanol.

Comparison of biomass-to-wheel (BTW) efficiency for different biomass utilization scenarios. only 7% of the chemical energy in corn kernels is converted to the kinetic energy on wheels, implying a great potential in increasing biomass utilization efficiency. Huang and Zhang. Click to enlarge. Huang and Zhang. Click to enlarge.
By comparison, syngas resulting from conventional gasification cannot be converted to pipeline quality natural gas without further processing, thereby adding cost. Instead, the process captures nearly all of the impurities found in coal, petroleum coke and biomass and converts them into valuable chemical-grade byproducts.
A series of catalytic fixed-bed reactors convert the syngas into gasoline and water via methanol and dimethyl ether intermediates. The low-cost, modular systems can be trucked in and assembled onsite for easy deployment. Syngas-to-Gasoline. Liquid/Gas Separation. The products are cooled and condensed.
This project will develop and evaluate a new process for converting biomass waste into diesel fuel. The diesel made from biomass will be a direct substitute for ultra low-sulfur diesel (defined by ASTM D 975). The biomass waste will first be converted into pyrolysis oil and then upgraded to diesel.
To smooth out the intermittency of renewable energy production, low-cost electrical energy storage (EES) will become necessary. electricity) to hybrid and electrical vehicles, although the cost of implementing EES is of great concern. The most commonly used systems today work by converting electricity to kinetic (e.g.,
The new catalyst is applied in a hybrid photocatalytic-electrolysis system that uses the photocatalytic reaction converting solar energy to lower the electrolysis voltage required for the hydrogen production by water electrolysis. The AIST team achieved an efficiency of 0.3%
It is a simple, low-cost approach that can be applied to a broad range of alloy systems with various working ions such as Li, Na, or Mg. By comparison, realized capacity in a graphite/copper composite anode is only ~ 150 mAh g -1. Eutectic alloys are fusible: upon cooling they convert from liquids to intimately mixed solids.

The modular system makes charging, converting and distributing electricity in electric vehicles cheaper by integrating several functions in one unit, depending on the design. Another separate device is the DC/DC converter which provides direct current from the high voltage battery to the 12 V power net – or it boosts 12 V to high voltage DC.
The function of the port is to convert AC power from the grid into DC, which is then applied to the battery. Thats because the charging stations convert DC power to high-frequency AC, using an inverter. In the first stage, AC power, either single-phase or three-phase, is converted to DC by an active rectifier. illustration).
