Tesla Giga Berlin is the largest taxpayer in Grünheide

Teslarati

For comparison, Lang stated that the entire budget for a community of 9,000 residents was about €20 million. High tech not only in production – at Giga Berlin we recycle up to 100% of our process water in our state-of-the-art waste water treatment plant.

HZB, 3M team explores water management in PFIA membranes for fuel cells; better performance at higher temps and low humidity

Green Car Congress

These additional acidic sites on each hydrophilic side chain provide additional protons for the proton transport and allow for the formation of larger water channels. The water management in the PFIA membrane is of interest, since it is crucial for the performance of the fuel cell: in order to function it needs to be humid but never wet.

NuScale and Prodigy sign MoU for marine-deployed generating station powered by NuScale SMR

Green Car Congress

Prodigy’s SMR Marine Power Station would be shipyard-fabricated, and marine-transported to its deployment location, where it would be moored in place in sheltered and protected waters at the shoreline. This translates to lower costs and shorter schedules in comparison to land-based deployments.

Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

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. In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%. It took us a long time to get the data needed to let us connect to the grid.

U Toronto and Fujitsu team use quantum-inspired computing to discover improved catalyst for hydrogen production

Green Car Congress

Green hydrogen is a carbon-free method that uses an electrolyzer to split water into hydrogen and oxygen gas. The low efficiency of available electrolyzers means that most of the energy in the water-splitting step is wasted as heat, rather than being captured in the hydrogen.

New Audi paintshop at Ingolstadt; heating energy & water per car down by 20%, CO2 by 30%, VOCs by 90%; bell-bell

Green Car Congress

Heating energy and water consumption per car are reduced by 20%. The new topcoat line is also a further component of the fully connected intelligent factory of the future. This comparison helps to prevent possible production flaws in the electronic quality process, with support from an electronic quality inspection.

Siemens integrates EV motor and inverter in single housing; common cooling and SKiN

Green Car Congress

A key feature of the integrated drive unit was therefore the creation of a special cooling water system around the motor and inverter. The coolest water first flows around very thermally sensitive components such as the IGBT modules and the intermediate circuit capacitor, after which it is led into the motor’s cooling jacket.
