Sentences with phrase «efficiency at full power»
The U.S. Department of Energy's Fuel Cell Technology Program claims that, as of 2011, fuel cells achieved 53 — 59 % efficiency at one - quarter power and 42 — 53 % vehicle efficiency at full power, and a durability of over 120,000 km (75,000 mi) with less than 10 % degradation.

And an additional 1,500 megawatts through energy efficiency and modernization of exisiting power plants by fixing current constraints that prevent certain plants from operating at full capacity, without building new power lines or new power plants.
In addition to their high efficiency, power density and uniform power development, they offer another advantage: unlike today's electric drive systems, they can develop their full power even after multiple accelerations at short intervals.
At any time, in any gear, the transmission collaborates perfectly with the engine enabling it to develop its full power and efficiency.
Consequently with the dramatic decrease in efficiency of fuel burn in the standby fossil fuel generators there is sweet FA practical reduction in CO2 emissions with the introduction of wind and solar power generation systems particularly when the energy costs of the producing and building the so called renewable energy systems are added to the grossly inefficient running of the ready to go to full generation capacity in minutes, fossil fuel powered standby generators which in many cases must be kept running at low or zero power generation to be able to come on line in minutes when the so called renewable energy systems fail to produce power,
The other absurdity, as recent detailed studies have confirmed, is that gas - fired power stations running on «spinning reserve» chuck out much more CO2 than when they are running at full efficiency — thus negating any savings in CO2 emissions supposedly achieved by the windmills themselves.
For long high speed trips the engine would be at full power max efficiency with exhaust capable of heating solid oxide electrolyser cell producing h2 and O per electric and water.
The hopefully millions of battery cars plugged into the grid can supply this surge power leaving only the minimum of base load generation running at full capacity and full efficiency.
