Construction begins on facility producing MSW-derived fuel PDF Print E-mail
By Accordant Energy LLC | March 08, 2018

Accordant Energy LLC, an innovative leader in the field of waste-derived engineered fuels, announced March 7 its licensee—RePower South LLC—has begun construction of its first Advanced Recycling and recovery facility, which will utilize Accordant’s patented ReEngineered Feedstock technology.

Located in Moncks Corner, South Carolina, RePower South will develop the Berkeley County Recycling and Recovery Facility using Accordant’s patented technologies to process 50 tons per hour of mixed municipal solid waste (MSW), recovering recyclable materials for sale in commodities markets, and producing a renewable solid fuel—ReEngineered Feedstock—from non-recyclables. Recovered commodities from the plant will include aluminum, scrap metal, OCC, mixed paper, PET, and HDPE, significantly improving recycling penetration in the plant’s service area.

Market demand for low carbon, renewable solid fuels is expanding as both large and small businesses seek cleaner forms of energy for manufacturing processes and electricity generation. ReEngineered Feedstock meets these needs through competitive attributes:

Low carbon – As calculated using the EPA’s Waste Reduction Model (WARM), each ton of ReEngineered Feedstock combusted results in a total reduction of approximately 2.5 metric tons of carbon equivalent (MTCO2E), realized through the avoidance of landfill disposal.

High calorific value – ReEngineered Feedstock has a higher heating value (HHV) approximating 10,000 Btu/lb., which is substantially greater than that of typical biomass (6,000 Btu/lb) and comparable to that of typical coal (12,000 Btu/lb).

Customized combustion properties – ReEngineered Feedstock can be engineered for a variety of combustion applications and is physically and chemically designed to mimic the properties of coal. This allows for more effective co-firing applications in cement kilns and boilers than realized by biomass and other alternative fuels.

Designation as a non-hazardous secondary Material - ReEngineered Feedstock holds a non-waste fuel determination from the EPA, allowing significant regulatory benefits for its users

Paula A. Calabrese, senior vice-president and chief strategy officer of Accordant, commented, “The RPS team has decades of experience in the recycling, solid waste, energy, finance, and construction industries, having built, owned, and operated multiple recycling and solid waste companies. We are confident this first commercial facility utilizing the Accordant technology will improve recycling performance and landfill diversion while providing a renewable solid fuel for cement kilns and utility and industrial boilers.”

Hondaís hydrogen fuel cell powered bike inches towards reality: Latest patent image shows a new desi PDF Print E-mail

The Hydrogen powered vehicles have an edge over electric ones in multiple ways. Unlike EVs, the hydrogen fuel cell vehicles do not have the issues of range and charging time as simply hydrogen gas has to be refilled in the system.

Honda has just filed a patent for its hydrogen fuel cell powered bike. The latest patent image shows the design of the motorcycle and it looks like a typical streetfighter. This is not the first time that Honda has filed patents for motorcycles running on fuel cell. However, the latest patent image shows the motorcycle is fitted with a redesigned swingarm. The central space of the motorcycle has been dedicated to the system that is responsible for the conversion of hydrogen into electricity. The hydrogen fuel cell that is positioned under the seat of the motorcycle is the place where hydrogen is mixed with oxygen with the help of a catalyst. Water gets out of the system as the only waste product. The hydrogen fuel cell powered vehicles have an edge over the electric ones in multiple ways. First and most importantly, such vehicles can be recharged quickly as simply hydrogen needs to refilled in the tank.

Electric vehicles, on the other hand, take some hours to get charged. However, the infrastructure for hydrogen fuel cell powered vehicles is an issue at present and it will be a matter of time when hydrogen filling stations get installed on roads in good numbers to facilitate the operation of fuel cell vehicles.

Honda is working on fuel cell powered vehicles for more than a decade now. Besides the new hydrogen fuel cell powered bike, the company must also have the roadmap ready for setting up infrastructure. If the infrastructure problem gets sorted out, the hydrogen fuel cell powered vehicles will prove to be a good and worthy alternative to the electric vehicles as they solve two major problems of EVs viz range and charging time. Honda's new hydrogen fuel cell powered motorcycle might make its debut as a concept model at the upcoming Tokyo Motor Show.

Buses, Trains and Automobiles: The Hydrogen Economy Is Coming To Town PDF Print E-mail

by Tina Casey on Friday, Mar 2nd, 2018


 The low carbon hydrogen economy of the future has been off to a slow start, but signs of a rapid acceleration are beginning to emerge. In the latest set of developments, the US Air Force is touting a zero emission renewable hydrogen fuel cell bus as a step toward additional Department of Defense applications, Canada is dropping hints that it would like to be the first country in the world with a full size hydrogen fuel cell passenger train, and the auto world is buzzing about Hyundai’s new Nexo fuel cell electric crossover SUV.


Welcome to the renewable hydrogen world

If you caught that thing about the Air Force and renewable hydrogen, that’s the key to the whole thing. Hydrogen is an abundant, zero emission fuel but it does not exist naturally in a usable state. It must be extracted from something else, and right now that something is primarily fossil natural gas.

The natural gas angle explains why the dream of a low-carbon economy powered by hydrogen has long been dismissed as a kind of sustainability oxymoron.

Fortunately for hydrogen fans, the picture has changed dramatically in just the last few years with the advent of low-cost solar and wind energy.

Low cost renewable energy means that electricity is freed from fossil fuel sources. That opens up the potential for using an electrical current (aka electrolysis) to produce renewable hydrogen by “splitting” water.

Renewable hydrogen from biogas is another sustainable option, but right now it seems that most of the R&D attention is going to water-splitting.

As for why bother producing hydrogen from water when you already have wind and solar energy generating whatever power you need, that’s a good question.

One answer is that hydrogen provides another energy storage option that helps ensure 24/7 power for wind and solar.

Transportation is another angle. Hydrogen can transported with existing pipelines, which could help reduce or eliminate the need for new pipelines and power lines.

It can also be packed into containers and shipped by road. That expands the use options into remote areas where the construction of new pipelines and power lines is not feasible.

Finally, hydrogen fuel cells may provide greater range and more muscle when used in vehicles, compared to batteries. That’s why fuel cells have been popping up in buses and trains as well as military vehicles, long haul trucks and SUVs.


Hawaii is one of several US states with comprehensive programs aimed at growing the hydrogen economy. The Air Force has been exploring fuel cells there in support of the state’s 100% renewable energy goals.

In the latest news, the Air Force is using a fuel cell electric bus to ferry up to 25 passengers around Joint Base Pearl Harbor-Hickam. The demonstration-scale project is designed to showcase how hydrogen and fuel cell technology can be applied to the Department of Defense.

The project actually dates back to 2006, when it began with a focus on demonstrating hydrogen compression, storage and dispensing. In 2010 it was revamped to focus more strongly on vehicles, including the use of hydrogen in internal combustion engines as well as fuel cells (fuel cells produce generate electricity through a reaction between hydrogen and oxygen).

Among the hydrogen vehicles involved in the project are an MJ-1E fighter weapons loader and a U-30 aircraft tug.

Here’s the Air Force explaining the benefits of hydrogen in terms of wind and solar grid integration:

In a hydrogen electrolysis unit, water is separated into hydrogen and oxygen using electricity. This hydrogen is collected, compressed and stored for fuel while the oxygen is either released into the air or can be collected and used in other applications. In many cases, excess electricity created during peak production by other renewable sources, such as wind and solar, can be used in this process to reduce cost and provide nearly emission-free fuel for the fuel cells.

The collected hydrogen can then be used in hydrogen fuel cells to create electricity as needed…

Outline for Europeís first waste to methanol plant PDF Print E-mail


 Enerkem teams up with AkzoNobel and Air Liquide to turn rubbish into raw materials

A facility to convert non-recyclable waste into valuable raw materials is being planned at the port of Rotterdam. Canadian company Enerkem, is working with AkzoNobel Speciality Chemicals, and industrial gases group Air Liquide to develop a plant that will convert 350,000 tonnes of waste, including plastics, into 270 million litres of ‘green’ methanol, each year.

Enerkem’s full-scale waste-to-biofuels facility in Edmonton, Alberta

The consortium says this represents the annual waste of more than 700,000 households and will avoid some 300,000 tonnes of carbon dioxide emissions. 

The methanol will be used as a biofuel, and by AkzoNobel to produce dimethyl ether, chloromethane and other chemical intermediaries currently produced from fossil fuel sources. Air Liquide will provide the oxygen, and together with AkzoNobel, the hydrogen required for the reactions. 

Marco Waas, director of research, development and innovation at AkzoNobel’s industrial chemicals business, described the project as ‘a significant step toward implementing a sustainable and circular chemical industry’. He added that the agreement came at ‘a very appropriate time given the current challenges in plastics recycling in Europe.’ Recycling plants are struggling to cope since China banned imports of plastic waste, from January this year. 

The firms will make a final decision on the $200m investment later this year, once permitting and detailed engineering planning are complete. However, Enerkem says there are currently limited support mechanisms to incentivise such sustainable chemistry initiatives: the Dutch government has undertaken to bring forward new policy measures to support the project.

 The plant will be twice the size of Enerkem’s waste to ethanol plant in Edmonton – expected to be at full production later this year. That facility initially produced only methanol to obtain sustainability certification, and to demonstrate purity and process viability to potential European partners. 

Enerkem’s four-step process begins with gasification of the waste. The gasifier contains hot sand at 700°C, steam and very little oxygen, so when it’s added, the waste is converted to carbon monoxide and hydrogen rather than being burnt. The synthetic gas is cooled and ‘scrubbed’ to remove impurities and contaminants. Edmonton’s facility doesn’t use renewable energy, but the heat is recovered and re-used in the gasifier to maintain the fluidity of the hot sand.

The syngas is heated again and the carbon monoxide and hydrogen combine at a specified temperature and pressure, in the presence of a copper catalyst. Lastly, the methanol is distilled from the gas.An Enerkem spokesman said the Rotterdam facility would benefit from ‘many small, but important’ process improvements that have been made since the Edmonton plant opened.


Research into the use of methanol as a ship’s fuel is already underway and more initiatives are needed, says the country’s Minister of Shipping and Waterways.

According to The Hindu, Nitin Gadkari made the comments during a ceremony at the Indian Institute of Technology in Madras (IIT-M) to mark the laying of a foundation stone for a national technology centre which will focus on the modernisation of India’s ports and inland waterways.

The Minister noted that the National Institution for Transforming India (Niti Aayog), a government policy think-tank established by the Narendra Modi administration, has already undertaken research into methanol, and he suggested that other institutions, such as IIT-M, could further this work and also look how India could manufacture its own methanol for industrial use.

Looking at the developing role of ports in India, Gadkari noted that the shipping industry had registered increasing profits since the BJP government came to power in 2014 and, he said: ‘This year, we are expecting profits up to ₹7000 crore.’
