Geely supporting Danish initiative on e-methanol with vehicle trials in Aalborg

Green Car Congress

Through Power to X (PTX), the conversion of renewable energy to other usable forms, green e-methanol is an optimal solution for Denmark to store excess renewable power, stabilize its national power grid, and produce a sustainable carbon neutral renewable fuel.

Fraunhofer analysis finds battery-electric trucks have energy cost advantage over hydrogen trucks

Green Car Congress

This is because hydrogen trucks have a decisive disadvantage: only about a quarter of the output energy flows into the drive, three quarters is lost through conversion losses. This is not likely to fail due to the resilience of the power grids—our trucks mainly load at midday and at night, when demand and prices are particularly low.

OptiFuel to repower Argentina’s 400 freight locomotive fleet from diesel-power to CNG and/or RNG

Green Car Congress

The energy coming from the nation’s electric power grid still emits large amounts of criteria and GHG emissions. For this reason, replacing diesel locomotives with 100% battery-electric power would emit more CO 2 into the atmosphere over a 10-year period than running 100% diesel over the same period, Optifuel says.

What Is Bidirectional Charging? Understanding the Benefits for Both Drivers and Businesses

EV Connect

With bidirectional charging, the batteries in our vehicles can not only provide fuel for the road but energy for our homes and even our shared electrical grid. In one-directional charging, alternating current (AC) electricity is converted to direct current (DC) energy that’s stored in an EV battery to power the car. Let’s take a look.

AC vs. DC Power: What's the Difference for Electric Vehicles?

EV Connect

DC Power DC electricity is current that constantly runs in one direction. This is the power found in fuel cells, solar cells and batteries. While DC power was mostly supplanted by AC for power grid purposes, it has made a resurgence lately due to many modern technologies running on DC power.
