Asia-Pacific has become the most important region in the world. A region in which the United States and China are fighting a battle for political and military dominance. As we told you in a past video, the distance separating these two powers is still worlds apart, yet China is committed to becoming a regional mega-power.

A team of researchers from Worcester Polytechnic Institute, Woods Hole Oceanographic Institution and Harvard University believes that the plastic amassing in floating islands in the oceans could be used to power the ships that are sent to clean them up. In their paper published in Proceedings of the National Academy of Sciences, the group describes how ocean plastics could be converted to ship fuel.

Prior research has shown that millions of tons of plastics enter the ocean each year—some of it is ground into fragments and disperses, and some of it winds up in colossal garbage patches floating in remote parts of the ocean. Because of the danger that such plastics present to ocean life, some environmentalists have begun cleanup operations. Such operations typically involve sending a ship to a garbage patch, collecting as much as the ship will hold and then bringing it back to port for processing. In this new effort, the researchers suggest it would be far more efficient and greener to turn the plastic into fuel for both a processing machine and for uninterrupted operation of the ships.

The researchers note that the plastic in a garbage dump could be converted to a type of oil via hydrothermal liquefaction (HTL). In this process, the plastic is heated to 300–550 degrees Celsius at pressures 250 to 300 times that of sea-level conditions. The researchers have calculated that a ship carrying an HTL converter would be capable of producing enough oil to run the HTL converter and the ship’s engine. Under their scenario, plastic collection booms would be permanently stationed at multiple sites around a large garbage patch, able to load the plastic it collects onto ships.

A new report, published this week, highlights the explosive growth in solar, wind, electric vehicles, and other clean tech in the United States.

Solar car is better option.

The influx of electric vehicles into Australia could put an additional load of 20 gigawatts a day — or a doubling of peak electricity demand — on the electricity grid by 2030 if most owners charged up at the same time every night, a new report has found.

The $350 million research collaboration between industry, universities and government has identified a raft of challenges for the arrival of EVs which are expected to make up 80 per cent of new vehicles sales by the end of the decade, making up almost 25 per cent of Australia’s total car fleet.

US-based Wright Electric has announced a 100-seat electric short-hop aircraft slated to go into service by 2026. It’ll either be powered by hydrogen, or it’ll use recyclable metal in what the company calls an “aluminum fuel cell.”

Wright is working on a number of large electric aircraft projects, including an even bigger 186-seater it’s developing in conjunction with European airline EasyJet and BAE Systems. This would be a “low-emissions” electric, presumably using a fossil-fueled range extender to top up its batteries and extend its flight range to around 1,290 km (800 miles). The partnership is pitching it as a “path” towards clean aviation, a kind of Prius of the skies, that will prove the electric powertrain while waiting for energy storage to come up to scratch.

Wright’s latest project, however, will be totally zero-emissions, and will use high-density energy storage to tackle flights up to an hour in duration – that’s enough for the ~1,000-km (620-mile) hop between Sydney and Melbourne, or London-Geneva, or Tokyo-Osaka, or LA-San Francisco.

Several countries are now leading the world in producing sustainable energy sources.
One of them is Chile, which has set its sights on becoming a leader in producing green hydrogen.
Many believe it could be a solution to replacing fossil fuels at a competitive price.

Decarbonisation of the iron and steel industry would require the use of innovative low-carbon production technologies. Use of 100% hydrogen in a shaft furnace (SF) to reduce iron ore has the potential to reduce emissions from iron and steel production significantly. In this work, results from the techno-economic assessment of a H₂-SF connected to an electric arc furnace(EAF) for steel production are presented under two scenarios. In the first scenario H₂ is produced from molten metal methane pyrolysis in an electrically heated liquid metal bubble column reactor. Grid connected low-temperature alkaline electrolyser was considered for H₂ production in the second scenario. In both cases, 59.25 kgH₂ was required for the production of one ton of liquid steel (tls). The specific energy consumption (SEC) for the methane pyrolysis based system was found to be 5.16 MWh/tls. The system used 1.51 MWh/tls of electricity, and required 263 kg/tls of methane, corresponding to an energy consumption of 3.65 MWh/tls. The water electrolysis based system consumed 3.96 MWh/tls of electricity, at an electrolyser efficiency of 50 KWh/kgH ₂. Both systems have direct emissions of 129.4 kgCO2/tls. The indirect emissions are dependent on the source of natural gas, pellet making process and the grid-emission factor. Indirect emissions for the electrolysis based system could be negligible, if the electricity is generated from renewable energy sources. The levellized cost of production(LCOP) was found to be $631, and $669 respectively at a discount rate of 8%, for a plant-life of 20 years. The LCOP of a natural gas reforming based direct reduction steelmaking plant of operating under similar conditions was found to be $414. Uncertainty analysis was conducted for the NPV and IRR values.
