Formic acid-based fuel cells represent a promising energy supply system in terms of high volumetric energy density, theoretical energy efficiency, and theoretical open-circuit voltage. They are also able to overcome certain problems inherent to traditional hydrogen (H 2 ) feed fuel cells such as safe handling, storage, and H 2 transportation.
CO2RR can produce diverse compounds including formate (HCOO-), carbon monoxide (CO), methane (CH 4), ethylene (C 2 H 4), and ethanol (C 2 H 5 OH). [2] The main challenges are the relatively high cost of electricity (vs petroleum) and that CO 2 is often contaminated with O 2 and must be purified before reduction.
Methanol reformers are used as a component of stationary fuel cell systems or hydrogen fuel cell-powered vehicles (see Reformed methanol fuel cell). A prototype car, the NECAR 5, was introduced by Daimler-Chrysler in the year 2000. The primary advantage of a vehicle with a reformer is that it does not need a pressurized gas tank to store ...
Nicholas Flanders describes the company's technology as "industrial photosynthesis" to create jet fuel and diesel from carbon dioxide. [ 21 ] [ 22 ] Their technology has been shown to convert CO 2 from raw biogas into carbon neutral methane .
The cell produces energy by combining carbon and oxygen, which releases carbon dioxide as a by-product. [3] It is also called coal fuel cells (CFCs), carbon-air fuel cells (CAFCs), direct carbon/coal fuel cells (DCFCs), and DC-SOFC. The total reaction of the cell is C + O 2 → CO 2. The process in half cell notation: Anode: C + 2O 2− → CO ...
A solid oxide electrolyzer cell (SOEC) is a solid oxide fuel cell that runs in regenerative mode to achieve the electrolysis of water (and/or carbon dioxide) [1] by using a solid oxide, or ceramic, electrolyte to produce hydrogen gas [2] (and/or carbon monoxide) and oxygen.
In November 2024, Bloom Energy (NYSE: BE) made a big announcement: It will be supplying a roughly 80-megawatt fuel cell project in South Korea. The project, assuming all goes as planned, will be ...
A deployment of Bloom Energy Servers outside eBay headquarters. The Bloom Energy Server or Bloom Box is a solid oxide fuel cell (SOFC) power generator made by Bloom Energy, of Sunnyvale, California, that takes a variety of input fuels, including liquid or gaseous hydrocarbons [1] produced from biological sources, to produce electricity at or near the site where it will be used.
