Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. Because so much energy is lost turning steam back into water in the Rankine cycle, at most a third of the power in the steam can be converted into electricity.
Water and oxygen are the only by-products. This enables them to take part in an accounting process that ensures that the amount of gas that they put in their vehicle at the natural gas filling station is supplied to the grid by the Audi e-gas plant. Payment and billing is handled via the Audi e-gas refueling card.

While the current facility feeds pure hydrogen (“WindGas”) directly into the gas grid, the new methanation plant provides for the generation of “green” methane. The wind-to-gas pilot plant “WindGas Falkenhagen” was constructed in 2013 to store wind energy in the natural gas grid. Type of CO2 source (biogas; waste water; atmosphere).
Powered by electricity, ERC combines captured carbon dioxide with water to produce high value materials that are conventionally obtained from the thermochemical processing of fossil fuels, including: formic acid, formate salts, oxalic acid, and methanol.
The Audi e-gas plant in the city of Werlte in Lower Saxony ( earlier post ) produces CO 2 neutral-fuel (synthetic methane from water, renewable electricity and CO 2 ); it now also contributes toward stabilizing the public power grid. This has resulted in the plant being accepted under the direction of grid operator Tennet TSO GmbH.
The goal is to develop an efficient and powerful test plant that will use carbon dioxide and water as well as electricity from renewable sources and bacteria to produce specialty chemicals. We are also contributing to the stability of the grid because production is so flexible that we can respond to fluctuations in power supply.
Today, new plants in Europe are already planned with a CO2-neutral energy supply from the start. With a CO2-neutral energy supply of the plants, we are consistently pursuing this approach and are actively driving sustainability in production. The decision also fits with our overall strategy.
The Audi e-gas plant uses the renewable electricity in the first stage for electrolysis—splitting water into oxygen and hydrogen (Audi e-hydrogen), which could one day power fuel-cell vehicles. The power-to-gas process links the electricity grid and gas network bi-directionally for the first time.
The e-gas project consists of two main components: Audi is contributing to the construction of offshore North Sea wind turbines which will generate clean power,that is then fed into the public power grid. If necessary, this energy can flow from the gas network back to the power grid at any time.

Sundsvall Energi, biogenic CO2 supplier and host for FlagshipTWO. In the Liquid Wind facility, green hydrogen will be produced from additional renewable electricity and water. The goal is to make the investment decision in late 2023, subject to environmental permitting process and extension of the electricity grid connection.
Further, open standards could increase the “food or fuel” dilemma associated to the use of first generation biofuels, i.e. biocrops, and the competition for land and water resources. It is also unclear how other environmental impacts of the production and use of different fuels would be accounted for.
Methanization works by producing methane (CH 4 ) and water (H 2 O) by catalytic conversion from carbon dioxide (CO 2 ) and hydrogen (H 2 ). Water causes problems with conventional processes, however; to remove it, serial methanization stages are typically required—with condensation areas in between. Schröter K.,
In the paper, the GM team broke down CO 2 and fuel consumption reduction potentials into several categories: The introduction of E-REVs and PHEVs to existing grids, displacing petroleum use; The influence of charging availability and consumer behavior on CO 2 reduction; Changes in power grid mix as well as vehicle stock; and.
This novel study examines the “micro grids” that owners of these resources likely will form for negotiating with their local utilities. The TomKat Center looks at generation and conversion, transmission and distribution, storage, and land and water as they pertain to energy for electricity and transportation. TomKat Center awards.
While hydrogen is most commonly created through steam methane reforming, it can also be created from water through electrolysis. Under this trial project, wind power will be used to turn water into oxygen and hydrogen, with the latter stored for use locally.
The new ARPA-E selections focus on accelerating innovations in clean technology while increasing US competitiveness in rare earth alternatives and breakthroughs in biofuels, thermal storage, grid controls, and solar power electronics. that produces large quantities of sugar and requires less water. heating and water purification.
Researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) have developed an electrocatalyst which operates at room temperature and in water for the electroreduction of dissolved CO 2 with high selectivity for ethanol. This could help to balance a grid supplied by intermittent renewable sources.

It has also established electric vehicle charging infrastructure across the country called Ather Grid. metric tonnes of CO2 emissions. Ather Energy is also aiming to use 80 percent of their energy consumption using solar energy and increase the ratio of recycled water to total water consumption by 84 percent.
Significantly to reduce the CO 2 intensity and water use of its manufacturing operations. At the Suzuka Factory, they solved this problem by developing a new paint specifically for the middle coat that allows a conventional water-based base coat to be applied wet-on-wet after a short pre-drying period. Earlier post.).
And oh BTW, according to the Energy Information Administration , California’s grid overall consumed 0% coal power. And the reality is that the grid in many parts of the country will get greener at a faster rate than the EV sales share. Said another way, residents of California purchased 390.9 of US EV sales in 2020.
and partners plan to perform a system integrated design study on an oxygen-blown gasification system coupled with water-gas shift, pre-combustion CO 2 capture, and pressure-swing adsorption working off a coal/biomass mix to yield high-purity hydrogen and a fuel off-gas that can generate power.
In parallel, more and more electricity is being generated from solar and water power. L/100 km (112 mpg US) is attained (equivalent to 49 g/km CO2). These forms of energy must also be used for mobility, Volkswagen says. However, the amount of renewably generated energy is subject to fluctuations due to natural factors (e.g.
One of the most common sustainability goals for businesses is reduce CO2 emissions. The source of the electricity – whether renewable sources like wind, solar, or water, or nonrenewable sources like coal – is also important. The report also mentions that high carbon intensity grids (i.e.

In the fight against climate change, many countries have pledged to reduce their CO2 emissions to net zero. The technology to produce hydrogen by electrolyzing water has been around for more than 200 years. The process emits about 10 tonnes of CO2 per tonne of hydrogen. Why all the hype about hydrogen?
EMPs can destroy electronic systems and overload power grids, causing blackouts. Climeworks Captures Double the CO2 for Half the Energy Climeworks Climeworks , a Zurich-based company, says its new direct-air capture (DAC) technology will remove millions of tonnes of carbon dioxide by the end of the decade.
Electric cars and a smart electric grid have a bright future, according to panelists at a roundtable discussion on the subject that I attended last Friday in Boston. “I Vehicle-to-grid is, I believe, the salvation of the automotive industry in the United States,” declared Marc Spitzer, an agency commissioner who was also on the panel.
Most automotive manufacturers say they plan to use renewable energy in the future, but for now, most battery production relies on electric grids largely powered by fossil fuels. That’s why operating EVs typically releases less carbon than operating gasoline vehicles of similar size, even in coal-heavy grids like Shandong or West Virginia.
