As bio, solar and computing inaugurate a spectacular Age of Convergence — the long-term opportunities in energy may well lie at sea. One of the perplexities of our time: why solar systems are so photon-efficient and so troubled in energy storage; conversely, how biomass systems are so photon-inefficient yet have magnificently dense energy storage options […]

Researchers say higher water use of energy crops must factor into sustainability debate

Researchers say higher water use of energy crops must factor into sustainability debate

August 30, 2011 |

In Illinois, researchers at the University of Illinois Urbana-Champaign say that the sustainability of water must be taken into effect when exploring large-scale production of biomass crops like miscanthus and switchgrass because of their much higher water use than corn. Because the grasses have more surface area and much denser growth than corn they lose […]

POET's new waste-heat recovery system saves water, gas, time

POET's new waste-heat recovery system saves water, gas, time

[ 0 ] April 27, 2011 |

In Michigan, POET has installed a new waste-heat recovery system at its ethanol facility in Caro that the company says will replace about 10 percent of the facility’s natural gas needs, and water that is condensed in the system is also reused, reducing water use by about 5 percent. The need for shut-down time will […]

Gimme money: Iowa county hits POET, Koch Resources with water rate increase

[ 0 ] April 7, 2011 |

In Iowa, three ethanol plants owned by POET and Koch Resources have been asked to pay more for their water by the local utility but POET won’t unless Koch does too. If they don’t agree to up their water rates, then the consumers in the Xenia Rural Water District—which announced it was going broke in […]

USGS warms that corn ethanol is stressing groundwater resources in Mississippi River Valley

USGS warms that corn ethanol is stressing groundwater resources in Mississippi River Valley

[ 0 ] December 2, 2010 |

In Mississippi, the US Geological Survey is warning that corn production for ethanol is having adverse effects on local water sources. Corn requires 80% more water than is needed to produce cotton in the Mississippi Delta requiring increased withdrawals of groundwater from the Mississippi River Valley alluvial (MRVA) aquifer for irrigation. This is contributing to […]

Water: Is there enough for biofuels at scale?

Water: Is there enough for biofuels at scale?

[ 0 ] August 25, 2010 |

Researchers publishing last year in AMBIO: A Journal of the Human Environment proposed that energy production systems be measured not only in terms of energy return on energy investment (EROEI), but energy return on water invested (EROWI). The researchers noted in “Burning Water”: “Water withdrawals are ubiquitous in most energy production technologies…several assessments suggest that […]
