Chances for Bio-LNG
Abstract An increasing effort is put into the utilization of organic waste streams in anaerobic digesters, producing useful products such as fertilizers and biogas. It becomes increasingly attractive to upgrade biogas to natural gas quality and consequently liquefy the gas to Bio-LNG. DMT Environmental Technology has been developing biogas treatment plants for over 25 years, closely following ...

Biogas upgrading: Membrane separation takes over
Abstract Due to governmental incentives and growing environmental awareness, it becomes increasingly attractive to upgrade biogas to natural gas quality and inject it into the natural gas grid or to use it as transport fuel. In this way, the biomethane can be utilized with the highest energy efficiency. Progressively, effort is being put into the utilization of organic waste streams in anaerobic ...

Aiming High Rewarding Ambition in Wind Energy - Report
EXECUTIVE SUMMARY With 392 GW installed, wind energy can be the single largest source of power generation in the EU by 2030 ahead of coal and gas. Wind energy already plays a significant role in the European power sector. In 2014, the wind industry installed 11,791 MW in the EU - more than gas and coal combined. Today wind energy can meet 10.2% of Europe’s electricity demand with a ...

Coal phase out case study: What Alberta can learn from Washington State
How Bruce Nilles and the Sierra Club cleaned up Washington state Renewable energy made up half of all the new power plantsconstructed in the world in 2014. That’s an incredible number made all the better when you think of what these plants are replacing. Big, bad coal. There are good reasons for this. Coal is not only the most carbon intensive form of energy available, but it has ...

Evaluation of anaerobic digestion processes for short sludge-age waste activated sludge combined with anammox treatment of digestate liquor
The need to reduce energy input and enhance energy recovery from wastewater is driving renewed interest in high-rate activated sludge treatment (i.e. short hydraulic and solids retention times (HRT and SRT, respectively)). This process generates short SRT activated sludge stream, which should be highly degradable. However, the evaluation of anaerobic digestion of short SRT sludge has been ...

The unconventional wisdom on renewable energy and investment
Over the summer, there has been a loud buzz in the media about the need for research and development that would lead to a breakthrough in the cost of clean energy technologies. Financial Times commentator Martin Wolf called for a “moonshot to save the planet” building on the proposal of noted academics and senior industry executives for an “Apollo mission” to put the ...

Highlights from DOE’s “Bioproducts in the Bioeconomy” Webinar
On Monday, October 26, 2015, the U.S. Department of Energy (DOE) presented “Bioproducts in the Federal Bioeconomy Portfolio Webinar,” a webinar on how the federal government is promoting sustainability through three different avenues: bioproducts research; commercialization; and market development. The presenters on these topics were DOE’s Bioenergy Technologies Office (BETO) ...

Effect of thermal and alkaline pretreatment of giant miscanthus and Chinese fountaingrass on biogas production
Giant miscanthus (Miscanthus×giganteus) and Chinese fountaingrass (Pennisetum alopecuroides (L.) Spreng), cultivated for landscaping and soil conservation, are potential energy crops. The study investigated the effect of combined thermal and alkaline pretreatments on biogas production of these energy crops. The pretreatment included two types of alkali (6% CaO and 6% NaOH) at 22, 70 and 100 ...

Wood instead of petroleum?
The other day I found an interesting article from Scientists at Johannes Gutenberg University Mainz (JGU) and at the University of Alabama in Tuscaloosa, USA. The artical discusses how the two recently managed to synthesize two complex chemical substances from wood-based starting materials. You can find the link here: Wood instead of petroleum. The basic chemistry is nothing new. In fact ...

Developing Decentralised Distributed Generation in Africa
Many countries in the developed world created power generation networks based upon large centralised power generation stations with significant investment in power transmission and distribution networks. From the African context this has not happened yet there is a huge need to increase power generation capacity. The thought of addressing this through a small number of large gas, hydro, coal or ...

California Changes Tax Law To Allow For Biodiesel Tax Exemption
On October 4, 2015, California Governor Jerry Brown signed Assembly Bill No. 1032, an act to amend Sections 60501 and 60505.5 of the Revenue and Taxation code, relating to taxation, into law. The bill adds biodiesel to the list of fuels that are eligible for tax refunds when they are used for nontaxable purposes. Starting on January 1, 2016, the State Board of Equalization will provide refunds on ...

Ethanol Mandates under RFS and EPA’s Lifecycle GHG Analysis
In a settlement with the American Fuel & Petrochemical Manufacturers (AFPM) and the American Petroleum Institute (API), the U.S. Environmental Protection Agency (EPA) agreed to set renewable fuel obligations for calendar years 2014 and 2015 by November 30, 2015, under the Renewable Fuel Standard (RFS). The RFS requires annual increases in the amount of renewable fuel that must be blended into ...

Over 170 Non-State Actors Have 80-100% Climate Commitments
A report by CDP and The Climate Group reveals that over 170 major companies, states, regions, and cities around the world have committed to reducing their greenhouse gas (GHG) emissions by 80-100%, or procuring 100% of their power from renewable sources. The findings reveal a trend toward increasingly ambitious climate action on the part of “non-state” actors (for example, ...

Pennsylvania House Of Representatives Votes To Remove Ethanol Blend Requirement
On September 25, 2015, the Pennsylvania House of Representatives voted to amend the Biofuel Development and In-State Production Incentive Act by removing a ten percent ethanol blend requirement that occurs when Pennsylvania ethanol production exceeds 350 million gallons. The Act was originally passed in 2008. Since the incentive was put in place, Pennsylvania has not come close to reaching the ...

California Air Resources Board Votes To Re-Adopt Low Carbon Fuel Standard
On September 25, 2015, the California Air Resources Board (CARB) voted to readopt the Low Carbon Fuel Standard (LCFS), and require a ten percent reduction in carbon intensity of transportation fuels by 2020. The LCFS targets were originally frozen due to a legal challenge. To address the court's ruling, CARB solicited public testimony before readopting an updated version of the LCFS. The modified ...

Recovering biomethane and nutrients from anaerobic digestion of water hyacinth (Eichhornia crassipes) and its co-digestion with fruit and vegetable waste
The potential to recover bioenergy from anaerobic digestion of water hyacinth (WH) and from its co-digestion with fruit and vegetable waste (FVW) was investigated. Initially, biogas and methane production were studied using the biochemical methane potential (BMP) test at 2 g volatile solids (VS) L−1 of substrate concentration, both in the digestion of WH alone and in its co-digestion with FVW ...

Biofuel CEOs Send Letter To President Obama Over EPA RFS Proposal
On September 16, 2015, 23 biofuel executives sent a letter to President Obama regarding the U.S. Environmental Protection Agency's (EPA) Renewable Fuel Standard (RFS) volume requirement proposal. The revised RFS allows companies to challenge the distribution requirement of renewable fuel, potentially resulting in RFS requirements being waived on a year-to-year basis. The letter outlines the ...
