If these regional rollouts are successful, hydrogen FCVs may be just a few years behind plug-in electric vehicle, not decades. Transition issues.
As money and policy increasingly favor gas and renewables, the rapidly electrifying energy system will deliver efficiency gains that outpace GDP and population growth. Natural gas will become the single largest source in 2026 and it will meet 25% of the world’s energy needs by 2050. trillion) and grid expenditure (US$1.5
The study, in press in the Journal of Power Sources , examines the efficiency and costs of current and future EVs, as well as their impact on electricity demand and infrastructure for generation and distribution, and thereby on GHG emissions. GHG emissions from electric driving depend most on the fuel type (coal or natural gas) used.
Utilities are racing to expand battery storage on the electricalgrid. The latest example is Pacific Gas and Electric Co., which submitted a request Friday to the California Public Utilities Commission to build and install four large banks of lithium-ion battery storage, according to the San Francisco Chronicle.

Public-private investment initiatives, government funding for infrastructure and consumer subsidies, falling production costs and notably, the commitment to future OEM launches of fuel cell electric vehicles (FCEVs)—all indicate a clear road to adoption. Myth #2: Hydrogen gas is dangerous to store and use.
Methanol (CH 3 OH) is mixed with water and fed directly to the fuel cell anode, where it is oxidized on a catalyst layer to form carbon dioxide, hydrogen ions (H + ) and the electrons that travel through the external circuit as the electric output of the fuel cell.
Frank doesn’t know too much about electric cars and didn’t do much research before doing his report. Frank doesn’t like electric cars very much and doesn’t want you to either. Why did he call his report, “Electric Cars Still Years Away?&# Does he really believe that fairtale?
For almost four years, her airport has been powered by a mix of on-site natural gas generators and solar panels. The airport estimates that the stand-alone system, known as a microgrid, has saved it about $1 million a year on its energy costs and allowed it to use the electricgrid as a backup, Ms. Cassotis said.
Results from the study also suggest that with sufficient coal plant retirement and sufficient wind power, controlled charging could result in positive net benefits instead of negative. The question of electricity costs vs. health and environmental cost is important to ask everywhere, Michalek said. Credit: ACS, Weis et al.
We think a plug-in offering 40 miles of gas- and emissions-free driving like the Volt is the sweet spot for the majority of customers because nearly 80 percent of drivers can drive their daily commute and return home for an overnight recharge that avoids inconvenience for them and additional daytime load on the electricgrid.

The task: make the most of a 30-watt fuel cell and 14 grams of hydrogen gas. Why a hydrogen truck?
Plug-in hybrid vehicles can be plugged into the electricgrid – such as a normal 120 volt household outlet - to boost mileage. This will allow the vehicles to operate on emissions-free batterypower, reducing the amount of fuel utilized and significantly decreasing the release of harmful pollutants, including greenhouse gases.
His team uses sophisticated simulation and modeling tools to address a dual challenge: scaling scientific discoveries from the lab while adapting to the dynamic realities of modern energy grids. For electrolysis to produce low-carbon hydrogen, the electricity used must be clean, he explained.
When you drive an old-fashioned gasoline-powered vehicle, you know your tank’s gallon capacity, as well as your typical mpg in town or on the highway. It is therefore easy to calculate how much gas you will need for a particular trip. instead of gas or diesel. EV batteries store and produce DC electricity, not AC electricity.
