Gasification of coal and biomass: a net carbon-negative power source for environment-friendly electricity generation in China

Xi Lu*

Realizing the goal of the Paris Agreement to limit global warming to 2 °C by the end of this century will require most likely deployment of carbon-negative technologies. It is particularly important that China, as the world’s top carbon emitter, avoids being locked into carbon-intensive coal-fired power generation technologies and undertakes a smooth transition from high- to negative- carbon electricity production. We focus here on deploying a combination of coal and biomass energy to produce electricity in China using an integrated gasification combined cycle system with carbon capture and storage (CBECCS). Such a system will also reduce air pollutant emissions, thus contributing to China’s near-term goal of improving air quality. We evaluate the bus-bar electricity-generation prices for CBECCS with mixing ratios of crop residues varying from 0% to 100%, as well as associated costs for carbon mitigation and co-benefits for air quality. We find that CBECCS systems employing a crop residue ratio of 35% could produce electricity with net-zero life-cycle emissions of greenhouse gases (GHGs), with a levelized cost of electricity (LCOE) of no more than 9.2 US cents per kWh. A carbon price of approximately $52.0/ton would make CBECCS cost-competitive with pulverized coal power plants. Therefore, our results provide critical insights for designing CBECCS strategy in China to harness near-term air quality co-benefits while laying the foundation for achieving negative carbon emissions in the long run.

Physics applications in eradicating Global Warming

Gregory Spaulding*

The UN Intergovernmental Panel on Climate Change (IPCC) have warned there is only a dozen years for global warming to be kept to a maximum of 1.5C. To restore carbon storage into
oceans, plants and landmasses thus first stabilizing new unwanted creations and then reducing greenhouse gasses like Carbon Dioxide and Methane before the Earth becomes like Venus. Common procedures over geologic time have changed the info and influenced both yield heat and outside temperature. It is the major issue. So, to eradicate this problem lot of experiment and my experiment is discussed below. The aim of this research is to basically show how physics applications are used to reduce Global Warming.
