100% renewable targets will require power storage to manage flows on the net
Electrolysers utilise these intermittent power flows to produce H2 gas from water
H2 gas can be stored in large quantities underground and transported via existing gas pipelines
H2 vehicles recharge faster and are more durable than battery powered transport
Growing H2 demand in industrial processes will reduce costs and increase supply

Engineers and scientists at the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL) have developed an app that focuses on hydrogen safety.

The Hydrogen Tools app, created with the support of DOE’s Office of Energy Efficiency and Renewable Energy, comes at a time when the use of fuel cells is growing. Fuel cells generate electricity by driving electrochemical reactions using hydrogen and air, producing power with dramatically reduced emissions compared to traditional hydrocarbon-based fuels.The only by-products are heat and water.

Nick Barilo, the PNNL project manager who led the team, said: “in addition to being a clean energy option, fuel cells can offer some real advantages in certain applications. Last year during Hurricane Sandy, for instance, cell phone towers that relied on a fuel cell as a backup energy source continued to work throughout the storm, with just a few exceptions, even in areas where cell towers relying on other power sources were rendered inoperable.”

“With hydrogen being deployed in a greater number of applications, it’s the perfect time to make a safety tool like this app broadly available. Many people are unfamiliar with the technology, and this app is intended to make the information they need available at their fingertips.

” Hydrogen Tools incorporates a variety of resources and web-based content to help those involved in designing, approving or using hydrogen fuel cell systems and facilities. It includes information about ventilation of hydrogen, safe distances and pressures for storing hydrogen, and best practices for safely handling hydrogen.

The tool was developed with funding from DOE’s Office of Energy Efficiency and Renewable Energy, which accelerates development and facilitates deployment of energy efficiency and renewable energy technologies and market-based solutions that strengthen U.S. energy security, environmental quality and economic vitality. –
