According to the company, wind farms at the end of their typically 25 years lifecycle are usually decommissioned and their equipment scrapped. Renewable Parts intends to salvage, repair and resell the "fully warranteed" parts at up to 40 pct below the cost of new parts.
The company will use its aftermarket spares warehouse in Renfrew near Glasgow to provide the turbine repair and recycle service, while engineering advice will be sourced from the University of Strathclyde and the Massachusetts Institute of Technology.

In reaching their conclusion, the researchers considered carbon taxes at $25 and $50 per ton of carbon emissions produced and two rates of increase -- 1 pct or 5 pct per year -- as well as three different approaches to dispensing the revenue: an equal rebate to every household; a tax break for individuals; or a corporate tax break.
The study showed that even the lowest taxation rates could lead to reductions sufficient to meet the U.S. near-term commitment under the 2015 Paris Agreement on climate change. However, the most efficient way of achieving those reductions, in terms of overall impact on the economy, is to use the revenue to reduce taxes on corporate profits or investment income. Rebating equal payments across the board was found to be the least efficient and individual tax breaks came in somewhere in between on both criteria. The researchers suggest a combination of tax breaks to corporations and rebates to the low-income families most affected by the tax could virtually eliminate the regressive aspects of the tax at very little cost in overall efficiency as well as be politically acceptable.
Their analysis indicates that starting with a $50 per ton carbon tax and increasing it by 5 pct per year would lead to a 63 pct reduction in total U.S. greenhouse gas emissions by 2050.

According to Penn State's College of Agricultural Sciences professor of bioproducts, Prof. Paul Smith, developing the capability to produce the huge volume of ASTM-certified, high-energy, dense biofuels needed by the airlines, and the logistics to handle the massive amount of feedstocks necessary has been a slow process. And now, oil prices in the low $40-a-barrel range are bogging the process down further, as the cost differential between petrojet and biojet widens and thus increases capital risk.
Smith's lab is part of a group that is evaluating regional supply chains that could be used for alternative jet fuel production, including feedstock production, transportation and fuel conversion. Researchers are examining fuel-production pathways, feedstock and infrastructure requirements, and commercial fuel demand to create scenarios for future production as well as identifying potential intermediate materials and co-products for each pathway to understand potential ways to aid in making biorefineries more economical. The project aims to identify key barriers that must be overcome throughout the alternative-jet-fuel supply chain to produce and effectively market 1 billion gpy of alternative jet fuel in the near term and 10 billion gpy in the longer term. The goal, Smith pointed out, has been to produce aviation biofuel from non-edible lignocellulosic feedstocks, such as timber harvests and crop residuals.
Penn State is part of a cooperative aviation research consortium known as the Center of Excellence for Alternative Jet Fuels and Environment, funded by the FAA, NASA, the Department of Defense, the EPA and Transport Canada. Led by Washington State University and Massachusetts Institute of Technology, the group is a coalition of 16 leading U.S. research universities and more than 60 private-sector stakeholders committed to reducing the environmental impact of aviation.

Fully 97 pct of MIT's greenhouses gas emissions are a result of buildings operations. Two pct of the emissions were "fugitive" that leaked from refrigeration equipment, among other sources. The remaining one pct of emissions was attributed to the school's vehicles fleet, according to an MIT release.
MIT has invested in energy efficient technologies and upgrades and cleaner fuels in order to achieve its targeted reductions improvements. The school is also cutting emissions by purchasing environmentally friendly electricity, upgrading its cogeneration power plant and various other measures.

The PetraNova project received $190 million in grant funding from the US Department of Energy -- a little under one-fifth of the project's costs -- but apart from that the project is entirely run on commercial terms, and can cover its costs at today's oil prices of about $50-$55 per barrel., according to NRG CEO Mauricio Gutierrez . By way of contrast, the other large carbon capture project now nearing completion in the US, Southern Company's Kemper plant in Mississippi, a regulated market, has gone way over budget and behind schedule. In 2010, its budgeted cost was agreed with the state's regulators at $2.8 billion. Now, with start-up scheduled for the end of this month, it is estimated at about $7 billion.
Petra Nova is fitted at a standard coal-fired unit, capturing the carbon dioxide from the flue gases using a process from Mitsubishi Heavy Industries that has been in use since 1999. NRG and JX have not revealed the cost of capture, but Jesse Jenkins of the Massachusetts Institute of Technology estimates that it works out at about $70 per tonne, unsubsidised. That is already lower than at the world's first large-scale carbon capture project at a power plant, at Boundary Dam in Canada. Completed in 2014, it cost more than Petra Nova, about $1.3 billion and captures less carbon dioxide at 1 million tpy.
