    Powerpaste packs clean hydrogen energy in[b] a safe, convenient gray goop[/b]

    February 02, 2021

    This sludgy gray goop is a clean, high-density, safe and easily transportable hydrogen energy fuel called Powerpaste

    Fraunhofer IFAM
    View 2 Images

    Fraunhofer researchers have presented a magnesium-based "Powerpaste" that stores hydrogen energy at 10 times the density of a lithium battery, offering hydrogen fuel cell vehicles the ability to travel further than gasoline-powered ones, and refuel in minutes.

    Typically, of course, hydrogen fuel cell vehicles carry their H2 fuel in gaseous form, stored in tanks at pressures around 700 bar (10,150 psi). These tanks are fairly large and heavy, which counteracts one of hydrogen's key advantages over today's lithium batteries – its higher energy density. The high pressures involved also make hydrogen an impractical option for powered two-wheelers like motorcycles and scooters.

    But a team based at the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM in Dresden have come up with an interesting new way to store and carry hydrogen energy, in the form of a magnesium hydride-based "Powerpaste" that stores the hydrogen in a chemical form, at atmospheric pressure, ready for release when needed.

    To produce the paste, magnesium is combined with hydrogen at around 350 °C (662 °F) and five to six times atmospheric pressure to form magnesium hydride. An ester and a metal salt are added to complete the process and form a viscous gray goop that can be loaded into cartridges.

    In Powerpaste form, it's completely stable at temperatures up to 250 °C (482 °F). It carries 10 times the energy of a similar weight in lithium batteries, and substantially more than a 700-bar H2 tank of the same weight. The researchers say vehicles running on a Powerpaste powertrain can expect a range "comparable to – or even greater than – gasoline."

    When it comes time to release the energy, a plunger mechanism extrudes the paste into a chamber where it reacts with water to release hydrogen at a dynamically controlled rate, which then feeds a fuel cell to create electrical power with which to run an EV powertrain or other device. Part of the paste's impressive energy density comes from the fact that half of the hydrogen released comes from the water it reacts with.
    The Fraunhofer team has built and tested this prototype power generator using a Powerpaste cartridge and a 100-watt PEM fuel cell

    Refueling a Powerpaste scooter, for example, would be a matter of pulling out the cartridge and replacing it with a full one at a service station. In this way, this stuff could become something like a bottle of BBQ gas: an easily replaceable way to use clean energy in a range of devices. The Fraunhofer team speaks of using it in large drones, putting a multiplier on their flight time and range, or in portable electric appliances, such as a paste-powered camping toaster or kettle, for example.

    And where removable cartridges might be just the ticket for some applications, others might find it easier just to pump the stuff into a tank – for example, fuel cell cars and trucks, aircraft and larger applications. The team says this sludgy goop can be supplied via standard filling lines with "relatively inexpensive equipment."

    Logistically, this stuff seems much simpler than regular gaseous (and certainly liquid) H2. It can be trucked around in barrels or tankers, and left more or less anywhere without danger. Fraunhofer IFAM is building a Powerpaste production plant at its own facilities, which will open later this year and have the capacity to make up to four tons of paste a year for pilot programs and industry evaluation. It also has a power generator up and running on the test bench in the lab.

    Questions remain, though. What happens to the magnesium as the paste is spent? Does it get recycled back into the process? Do the energy density figures quoted above take into account the entire system required, or just the fuel storage? How much water does it use for a given amount of energy, and how much water do you need to add when you fill up, given that fuel cells produce water as a by-product?

    Perhaps most importantly, how energy-efficient is the process of making this paste? Let's not forget, one of the black marks against clean hydrogen in fuel cell systems is its horribly inefficient use of clean energy. Store clean energy in a battery and you'll get more than 90 percent of it back at the wheels. Store it in hydrogen and you torch at least half of it in lossy processes along the way.

    The production of Powerpaste requires heat, pressure and industrial processes, all of which cost energy. Add to that the financial and energy costs of storage and transport, and the equations are likely to make gaseous H2 look like a very frugal little energy holder by comparison.

    As long as Powerpaste is produced using nothing but clean energy, it still looks like a clean fuel – and perhaps a very convenient one that we can imagine rolling out to gas stations without too much fuss. But in a world where clean energy production is still limited, it may end up looking like a wasteful use of our solar and wind resources.

    And then there's the matter of cost; how will Powerpaste compare to gasoline on a fill-up, given that it'll deliver roughly the same range? Certainly, it'll be a lot to begin with and would come down with scale and the price of clean H2. But the added processing and transport costs will make it more expensive than straight hydrogen gas, and a ballpark future figure could definitely be instructive. We'll put these questions to the researchers and see how things start to stack up.

    Trash trap gets to work removing plastic waste from Vietnam's Red River

    February 03, 2021

    A locally designed, inexpensive trash trap has been installed along Vietnam's Song Hong River to remove floating debris such as plastic waste

    Removing the vast amounts of plastic waste already polluting our oceans is going to need tackling in a number of ways. But the flow of plastic from rivers also needs to be stopped, and that's what Vietnam's trash traps are designed to do.

    They may not look quite as swanky as the Interceptors from the Ocean Cleanup, but the idea is similar. The first in a series of trash traps installed along Vietnam's Song Hong, the country's second-longest river also known as the Red River, is designed to remove floating debris from the water as it flows towards the Gulf of Tonkin.

    "The latest science confirms that we need a suite of solutions to fight ocean plastic pollution, from reducing our reliance on virgin plastics to improving waste collection and recycling to cleaning up the plastic waste that does end up in the environment," says the Ocean Conservancy's Chever Voltmer. "Rivers often serve as a pathway for plastics to travel out to sea, so trash trappers like these are important cleanup tools. What makes this particular model so unique and promising is that it is inexpensive, locally designed, and made from locally sourced materials."

    The trash traps are the work of Vietnam's Centre for Marinelife Conservation and Community Development (MCD), which has been testing them in the Song Hong for about a year – collecting more than 18 tons of floating waste in the process. Now, thanks to funding through the Benioff Ocean Initiative's Clean Currents Coalition, more installations along the river and its tributaries in Nam Dinh province are being rolled out over the next two years.

    Where the Ocean Project's Interceptor is a barge-like vessel designed to remove plastic as it patrols rivers, the trash trap features floating booms and platforms connected to the riverbank.

    During the grant period, a local team will remove and sort trapped debris every three days. Plastic waste such as bottles will be sold to recycling facilities, while lower-grade plastic from the likes of bags and films will be processed at a special facility in Nam Dinh. Data on the operation will be analyzed by members of the Ocean Conservancy and Vietnamese scientists to inform future waste strategies.

    It doesn't appear that the solution is designed to deal with microplastics, but with MCD looking to build a network of traps in the Song Hong delta, it could help stem the tide of plastic waste entering the seas and oceans from Vietnam's rivers.

    in de lijn van Powerhouse ben ik ook tegen Ceilo Waste energy aangelopen. Canadese variant, maar blijkt met een aardig initiatief afval om te zetten in biodiesel.

    Jullie bekend? Volume is aardig hoor al zie ik en zit rond zelfde prijs range als powerhouse. Even in de gaten houden..

    HYDROGEN UTOPIA INTERNATIONAL DELIVERS FIRST POLISH CENTRE OF HYDROGEN POWERED BY A UK LICENSED SYSTEM
    11th February 2021

    Hydropolis United sp. z o.o. in cooperation with the city of Konin have reached an agreement to create The First Polish Centre of Hydrogen.

    The agreement was reached with the Mayor of the City of Konin- Mr Piotr Korytkowski.

    Konin expressed the desire of becoming the first city on the European Continent to apply the UK licensed DMG System in order to tackle the most burning environmental and socio-economical issues which are

    Unrecyclable plastic. - The European Union has banned all non-recyclable plastic waste being shipped to developing nations from 1 January.

    High CO2 Emissions

    Rapid job loss & City depopulation

    THE POLISH CENTRE OF HYDROGEN:

    The goal of this unique initiative in Poland was only possible thanks to a close collaboration between the UK licensor of the unique plastic to hydrogen technology and Hydrogen Utopia International, LTD which acquired a licence to use the licensed system in Poland.

    The project in its full scale will contain 10 units. The units will be placed all together in one location. The site is one that Hydrogen Utopia International Ltd has received a legal access to commence planning applications, necessary permits and EIA and for this purpose HUI has engaged SWECO to commence the process.

    The systems will be rolled out in a sequence according to the support of the respective public institutions.

    In order to help building the first plant, Hydropolis United with the collaboration of Konin applied for EUR 12 million under the EU Innovation Grant. In order to build the first centralised DMG centralised plant EUR 60 million is to be applied for from the Just Transition Fund which will be matched by funds from the Polish Government under the JUST Transition fund terms of Government matching funds.
