Carbon capture from the industrial sector

Science

Cement factories are prime targets for the installation of carbon capture technology. Carbon capture aims to reduce the amount of carbon dioxide being emitted into the atmosphere. This carbon dioxide can then be either stored or used (for example, as a chemical feedstock). Most studies have focused on carbon dioxide emissions from power generation. Psarras et al. instead estimate the cost of carbon capture from the industrial sector, which contributes almost a quarter of carbon dioxide emissions.


Machine Makers Set To Drive A New Low-Carbon Industrial Revolution

Forbes - Tech

Some of the world's biggest companies are the makers of capital goods – the machines, buildings and equipment that keep the global economy going. As a result, these heavy industry manufacturers are some of the world's biggest emitters of greenhouse gases (GHGs). And yet, because of the products that they make, which high-emitting sectors such as power generation, buildings and transport rely on, they can be part of the solution to climate change as well. That is exactly what many of them are doing, according to a new report'Bridging low carbon technologies' from environmental non-profit and investment research provider CDP. CDP, formerly known as the Carbon Disclosure Project, says that innovation in the capital goods sector is driving a low-carbon industrial revolution by harnessing the trends of electrification, digitization and automation to open up new market opportunities in transformative and radical technologies in areas ranging from microgrids to machine autonomy and from energy storage to hybrid renewables.


South Africa Ready For Low-Carbon Energy Production With New Nuclear And More Renewables

Forbes - Tech

On March 31st, the Department of Energy in the Republic of South Africa finishes its public comment period on how the country plans to move away from coal and towards low-carbon sources like nuclear and renewables. South African Minister for Energy Tina Joemat-Pettersson delivers a speech at the opening session of the 58th general conference of the International Atomic Energy Agency (IAEA) on September 22, 2014 in Vienna. This is not a simple move. Generation of electricity in South Africa is overwhelmingly dominated by coal, particularly low-grade coal, and the country uses coal to generate a third of its liquid fuels as well. Over 90% of electricity comes from coal, with only 3% from nuclear, 3% from natural gas and 2% combined from conventional and pumped hydroelectric.


Strong winds and clear skies help set UK renewable energy record

Engadget

This week saw more milestones for renewable energy after the National Grid confirmed that power from green sources supplied more than half of UK energy for the first time. On Wednesday lunchtime, power from solar, wind, hydro and biomass accounted for 50.7 percent of energy production. In another UK first, nuclear, wind and solar each generated more electricity than coal and gas combined. In a tweet, The National Grid confirmed: "For the first time ever this lunchtime wind, nuclear and solar were all generating more than both gas and coal combined." Favourable weather played its part, thanks to clear skies and very strong winds.


Burning wood can be a clean source of power after all

The Japan Times

Burning large amounts of wood from forests can cut greenhouse gas pollution -- but only alongside policies that encourage new trees to quickly absorb carbon dioxide. That's the conclusion of new research published in Science Advances, which seeks to counter the prevailing view that biomass can worsen climate change. Energy companies in the U.S. and Europe -- including Drax Group PLC, once the U.K.'s biggest coal power plant -- are turning to biomass fuels harvested from forests or farms as a way to wean themselves off coal. While wood is the largest biomass source, it can also come from other organic matter such as crop waste or even garbage. That material is then burned to run steam turbines that produce electricity (and heat as a by-product) that can be piped to homes.
