Hi Reddit!

Hydrogen in combination with renewable energy (e.g., wind and solar) is being considered as an alternative to fossil fuels as a zero-emission vehicle fuel as well as to reduce carbon in all energy sectors. Fuel cell electric vehicles are available from major automotive manufacturers and complement battery electric vehicles by providing long range (>300 miles) and rapid refueling (3-5 minutes). Hydrogen fuel cell-powered forklifts have replaced more than 10,000 battery units and growing rapidly, while hydrogen fuel cell auxiliary power units keep phone cell towers operational in the event of natural disaster. The potential for hydrogen to reduce carbon emissions in the energy sector is almost limitless. Hydrogen can be used as a fuel much like natural gas (NG) and is easier to produce than synthetic NG from renewable energy sources (such as solar and wind power) making hydrogen an important storage component to renewable portfolio standards. Hydrogen can also replace carbon-intensive processes in industry, such as for heating and steel manufacturing. It may not be the solution to all of our energy challenges, but hydrogen enables a domestically-produced secure and sustainable energy future.

I will be back at 5 pm ET (2 PT) to answer your questions, ask me anything!
