Harworth Opens Wind Turbine Project

Joanna Schroeder February 3, 2015

UK-based Harworth Estates has completed the installation of a 500 kW wind turbine located at the former Arkwright surface mine, near Chesterfield, Derbyshire. The project was completed in partnership with Energy Prospects Co-operative. The site forms part of the former Arkwright open cast mining operation, which has been reclaimed and restored to agricultural land. Energy Prospects Co-operative raised money to fund the development of the turbine through a public share offer, giving priority to those who live locally.

According to Harworth Estates, the operating wind turbine generates sufficient energy to power around 1,000 local homes. Energy is fed into the National Grid, utilizing the grid connection adjacent to the turbine site.

Harworth is also working with Energy Prospects Co-operative to develop a second 500 kW turbine at the former Shafton Two Gates colliery site in Barnsley, South Yorkshire. Work have already begun and the turbine is expected to be operating by summer of 2015. Harworth Estates and Energy Prospects Co-operative are also currently working on planning applications for two further single turbine projects. One is near Edlington, Doncaster, and another near Selby, North Yorkshire.

Hannah Moxon, assistant management surveyor, of Harworth Estates’ Natural Resources division, said, “These two projects demonstrate our expertise at transforming previously-developed land to support low-carbon energy projects. Funding through the share offer created a lot of local interest and support for the project. These wind turbines are an important part of Harworth’s commitment to the community and the environment. We also look forward to continuing to work with Energy Prospects on single turbine schemes on our other sites.”

Pioneering Solar-Powered H2O Desalination Plant

Joanna Schroeder February 3, 2015

Abengoa has been selected by Advanced Water Technology (AWT) to jointly develop a large-scale desalination plant powered by solar energy. The plant will be located in Saudi Arabia and the according to AWT, when complete will the first and largest of its kind in the world. It will produce 60,000 m3 of water each day to supply Al Khafji City in North Eastern Saudi Arabia, ensuring a constant water supply throughout the year.

According to Abengoa, the photovoltaic plant will be capable of supplying the power required by the desalination process, significantly reducing the operational costs. It will also have a system to optimize power consumption and a pre-treatment phase to reduce the high level of salinity and the oils and fats that are present in the region’s seawater.

The Al Khafji desalination plant will ensure the stable supply of drinking water, contributing to the country’s socio-economic development. As in other cities in Saudi Arabia, water is a scarce resource. Abengoa and AWT will supply the local population with water needs in a sustainable and reliable way.

Solar Changing Hawaii’s Electric Future

Joanna Schroeder February 3, 2015

Hawaii has been getting a lot of attention recently for its efforts to reduce its use of fossil fuel-based energy. The state has the highest electricity costs in the U.S. Most recently, NextEra Energy announced its intent to acquire Hawaiian Electric Industries who owns three electric utilities that supply power to 95 percent of the state’s population. NextEra Energy Resources is one of the largest developers of renewable energy in the U.S. and intends on continuing the trend of adding solar power to its portfolio.

According to a recent “Today in Energy” published by the Energy Information Administration (EIA), high electricity prices in Hawaii have made wind and solar technologies economically attractive alternatives – even more so as prices have come down in recent years. This has led to a growing use of wind and solar energy at both utiity scale and in distributed applications such as rooftop solar PV.

EIA’s monthly net metering utility data finds 9,200 net-metered PV systems were added in 2014 through October, bringing the total number of customers with net-metered PV to around 48,000. In Oahu, where most of the state’s population resides, the Solar Electric Power Association finds that roughly 12 percent of customers have rooftop solar compared to only .5 percent average throughout the rest of the U.S. The average capacity of residential net-metered PV systems in Hawaii has also been increasing as larger and more efficient PV systems are installed.

However, the state has seen delays in adding additional solar to the power grid. EIA attributes the delays to circuits on the Hawaiian Electric distribution grids reaching levels of rooftop PV capacity that are 120 percent or more of the circuit’s daytime minimum load—a key threshold for Hawaiian Electric’s interconnection approval process. Once that threshold is passed, an interconnection study may be required before the new PV system can be approved, which has resulted in a backlog of PV applications.

EIA notes that Hawaiian Electric recently entered a cooperative research partnership with the National Renewable Energy Laboratory, the Electric Power Research Institute, and SolarCity to study the operational effects of high levels of solar PV on electric grids.Preliminary research results have lead Hawaiian Electric to announce plans to clear its backlog of PV applications by April 2015.Read More

Bacterium, Nitrogen Gas to Partner for Ethanol

John Davis February 3, 2015

Researchers at the University of Indiana might have come upon a way to partner bacterium with nitrogen gas to make more ethanol. This news release from the school says biologists there have found a faster, cheaper and cleaner way to increase ethanol production by using nitrogen gas, the most abundant gas in Earth’s atmosphere. The discovery could help make cellulosic ethanol more competitive with corn-based ethanol.

The raw materials for cellulosic ethanol are low in nitrogen, a nutrient required for ethanol-producing microbes to grow, so cellulosic ethanol producers are estimated to spend millions of dollars annually on nitrogen fertilizers like corn steep liquor and diammonium phosphate. But an IU team led by biologist James B. McKinlay has found that the bioethanol-producing bacterium Zymomonas mobilis can use nitrogen gas (N2) as a nitrogen source, something that the more traditional ethanol-producer, baker’s yeast, cannot do.

“When we discovered that Z. mobilis could use N2 we expected that it would make less ethanol. N2 utilization and ethanol production demand similar resources within the bacterial cell so we expected resources to be pulled away from ethanol production to allow the bacteria to grow with N2,” McKinlay said. “To our surprise the ethanol yield was unchanged when the bacteria used N2. In fact, under certain conditions, the bacteria converted sugars to ethanol much faster when they were fed N2.”

Knowing the bacterium could use N2 without hindering ethanol production, the team reasoned that N2 gas could serve as an inexpensive substitute for nitrogen fertilizers during cellulosic ethanol production.

“Until recently, ethanol has been produced almost entirely from food crops, but last year there was a surge in cellulosic ethanol production as several commercial facilities opened,” McKinlay said. “Cellulosic ethanol offers more favorable land use and lower carbon emissions than conventional ethanol production. Even so, cellulosic ethanol is struggling to be cost-competitive against corn ethanol and gasoline.”

The researchers believe N2 gas, which can be produced on-site at production facilities, could save an ethanol production facility more than $1 million dollars a year. They have filed for a provisional patent on the idea.

Springboard Biodiesel Partners with 75th School

John Davis February 3, 2015

Biodiesel equipment manufacturer Springboard Biodiesel has hit a bit of a milestone. The company says the Putnam County School system of Georgia will be the 75th school to own and operate a BioPro™ biodiesel processor.

“Putnam is doing what any school with dining facilities on campus can do,” reports Springboard Biodiesel CEO Mark Roberts. “Converting used cooking oil into locally made fuel for less than a dollar per gallon saves money on fuel costs, significantly reduces a school’s carbon footprint and makes students smarter.”

Springboard offers financing through several third party lenders thereby enabling any accredited US educational institution to get started quickly with a program that compliments many existing recycling programs.

Some of Springboard Biodiesel’s other customers for its small-scale biodiesel processing systems include Toyota, Honda, The Florida National Guard, The Petroleum Corporation of Jamaica, Jimmy Dean Sausages, many restaurants and schools, and the Federal Prison system.

Book Review: Fractured Land

Joanna Schroeder February 2, 2015

When is the last time you filled up your tank with a gallon of gas that was less than $2? For me, today. As oil prices have plummeted with gas prices falling suit, many people are attributing all the extra oil to fracking. But what is the cost, financially and environmentally speaking, of oil drilled in this manner?

A new book by Lisa Westberg Peters, “Fractured Land: The Price of Inheriting Oil,” takes a look at these very issues. Interestingly, Peter is a self-proclaimed environmentalist who inherited land in North Dakota that is part of the state’s “fracking” oil boom. She acknowledges her discomfort with fracking technology, but attempted to keep an open mind during her educational journey to learn more.

When Peters father passes away and she is going through his things, she comes across all the documents related to his oil/fracking royalties that she will eventual inherit. The book follows her as she learns more about her family’s oil history, her research about fracking, which she is theoretically opposed to, and the family’s trip to North Dakota, where they have oil contracts, and spread her father’s ashes. The prose flows nicely as she weaves in and out between her family history and the information she learns about fracking.

From an energy perspective, despite being from the Midwest and current residing in Minnesota, she is opposed to the use of biofuels. She writes, “We don’t have petrochemicals in Minnesota, so we grow corn for ethanol. Homegrown alternative energy! I should be enthused about ethanol, but the production plants are water and energy hogs.”

Peters does address the chemicals and water used in fracking, albeit briefly and I feel she could have done a better job of addressing her environmental concerns over some of the issues brought on by fracking (potential for contaminated water, excessive water use that is much worse than other forms of alternative energy, mining of the frac sand, etc.).

Ultimately she chooses to keep her mineral rights when they come to her but she decides to donate a portion of them back to North Dakota to aid those who are struggling with high rents or the natural areas threatened by oil development. She concludes that while she will benefit financially from oil drilling, it brings her little joy.

Alt Electricity Surpasses Natural Gas

Joanna Schroeder February 2, 2015

According to the latest “Energy Infrastructure Update” report from the Federal Energy Regulatory Commission’s (FERC) Office of Energy Projects, new renewable energy sources generated more capacity than natural gas in 2014. Sources including biomass, geothermal, hydroelectric, solar and wind provided 49.81 percent (7,663 MW) of new electrical generation brought into service. Natural gas accounted for 48.65 percent (7,485 MW). By comparison, in 2013, natural gas accounted for 46.44% (7,378 MW) of new electrical generating capacity while renewables accounted for 43.03% (6,837 MW).

New wind energy facilities accounted for 26.52 percent of added capacity (4,080 MW) in 2014 while solar power provided 20.40 percent (3,139 MW). Other renewables – biomass (254 MW), hydropower (158 MW) and geothermal (32 MW) – accounted for an additional 2.89 percent.

For the year, just a single coal facility (106 MW) came online; nuclear power expanded by a mere 71MW due to a plant upgrade; and only 15 small “units” of oil, totaling 47 MW, were added.

Renewable energy sources now account for 16.63 percent of total installed operating generating capacity in the U.S.:

water – 8.42%
wind – 5.54%
biomass – 1.38%
solar – 0.96%
geothermal steam – 0.33%

Renewable energy capacity is now greater than that of nuclear (9.14%) and oil (3.94%) combined.

“Can there any longer be doubt about the emerging trends in new U.S. electrical capacity?” noted Ken Bossong, executive director of the SUN DAY Campaign. “Coal, oil, and nuclear have become historical relics and it is now a race between renewable sources and natural gas with renewables taking the lead.”
