Fossil-free plastics production to start with sustainable polymer tech
World’s first industrial-scale fossil-free plastics production complex to be built in Belgium.
The world’s first industrial-scale fossil-free plastics production facility is set to be established in Belgium. The facility will use Lummus’ proven sustainable polymer technology. Vioneo has Lummus as its facility’s polypropylene partner.
The complex will also be highly electrified using renewable electricity and use renewable hydrogen as key components to its operations.
The company claimed that plastics produced will be fully traceable and CO2 negative, allowing customers to reduce their Scope 3 emissions.
Solar trees provide opportunity to meet renewable energy targets without deforestation
With the right technology, solar energy has the potential to meet all of the world’s electricity needs, but we are still a long way off from that point. Still, governments around the world are setting high objectives for renewable energy. Many world leaders have set commitments to phase out coal power and transition away from fossil fuels, and solar panel installations are currently one of the top contenders for implementing these plans.
However, solar energy has a bit of a dark secret. In some places, putting up these massive solar panel installations requires cutting down hundreds or even thousands of hectares of forests over time. In South Korea, deforestation caused by solar installations affected 529 hectares of forest in 2016, 1,435 hectares in 2017, and 2,443 hectares in 2018.
Of course, there are some solar installations located in deserts or other treeless landscapes that don’t have this issue. But those that do end up cutting out an incredibly important carbon sink, first worsening the problem they are attempting to alleviate. This deforestation then causes further issues with erosion and the destruction of natural habitats.
Sunlight-powered catalyst sets new standard for hydrogen peroxide production efficiency
Hydrogen peroxide (H2O2) packs so much chemical energy into a small space that it is powerful enough to fuel rockets. But this same ability to concentrate energy also makes hydrogen peroxide useful for more earthly energy applications, such as powering fuel cells. It also holds promise as a green and sustainable energy source: when hydrogen peroxide releases its stored energy, the main byproduct is simply water.
3D-printed gyroidal solid oxide cells offer lighter, more compact energy solutions
Over the past decades, energy engineers have been developing a wide range of new technologies that could power electronic devices, robots and electric vehicles more efficiently and reliably. These include solid oxide cells (SOCs), electrochemical devices that can operate in two different modes, as fuel cells or as electrolyzers.
US reactor turns cow manure into jet fuel at fraction of normal cost
US startup turns cow manure into jet fuel in a move to reshape renewable energy.
Interestingly, the reactor does it all at just 1/100th the capital cost of conventional systems. The dramatic reduction in capital expenditure could make on-site fuel production a realistic prospect for individual farms.
Over 20,000 large livestock farms in the U.S. produce nearly a trillion pounds of manure annually, but less than 6% capture the biogas from this waste.
“Farmers in the U.S. and around the world are sitting on an untapped goldmine. We’re giving them the ability to turn waste into a profitable product that airlines desperately need,” said Dr. Stephen Beaton, CEO and Founder of Circularity Fuels, in the press release.
