Heating Buildings With Solar Energy Stored in Sand

Cars That Think

In a region known for long, dark winter nights, Polar Night Energy is building a system in the city of Tampere that can heat buildings with stored solar energy — all day, all night, and all winter long. This means that storing and distributing energy is as important as its generation. The apparent contradictions do not end there.

EU Innovation Fund grants €108M to RWE’s waste-to-hydrogen project FUREC

Green Car Congress

For comparison: This is equivalent to the output of a 700-megawatt offshore wind farm with coupled electrolyzers. The CO 2 released during the hydrogen production is captured and can be stored or possibly used as a raw material by industry in the future. The plant is expected to produce 54,000 tonnes of hydrogen per year.

Shell to build one of Europe’s biggest biofuels facilities for SAF and renewable diesel; 820,000 tonnes/year

Green Car Congress

Shell expects to capture carbon emissions from the manufacturing process and store them in an empty gas field beneath the North Sea through the Porthos (Port of Rotterdam CO? When built, Porthos will transport and store CO 2 that is captured by various companies, including Shell. Transport Hub and Offshore Storage) project.

Opinion: Reinventing fuel-based power for a more secure and resilient grid

Green Car Congress

It is, however, a challenge that is being made all the greater as we continue to decentralize power generation with more distributed, variable and inflexible sources, such as wind and solar. Increasingly, wind and solar are replacing fossil fuels as our principle source of energy. 100% wind and solar is not feasible on its own.

Fraunhofer IFF team designing hydrogen factory of the future

Green Car Congress

Electricity sourced from sun and wind is used to split water into hydrogen and oxygen in a process called electrolysis. The hydrogen is stored and can be converted by fuel cells in vehicles back into electricity that powers them. It is not possible to build wind and PV plants everywhere.

kWh/100 km according to NEDC,) has been delivering urban driving fun and locally emission-free go-kart feeling in MINI style since 2020. Four wind turbines on the site of the BMW Group plant in Leipzig supply the electricity needed for its production. kWh/100 km according to WLTP, 14.6 - 14.0 kWh/100 km according to WLTP, 16.9 - 14.9

Researchers demonstrate efficient electrochemical reduction of CO2 to C2+ alcohols

Green Car Congress

When powered by renewable solar or wind energy sources, the electrocatalytic CO 2 reduction reaction (CO 2 RR) is a promising approach to produce value-added chemicals/fuels and store renewable energy to achieve the goal of net-zero-emissions. 2020.12.011.
