The Role of Carbon Capture and Storage in the Energy Transition

Abstract

In this paper, we review and analyze the salient features of the ongoing energy transition from a high to a low carbon economy. Our analysis shows that this transition will require decarbonizing the power, transport, and industry sectors, and the transition pathway will be country-specific. Carbon capture and storage (CCS) technologies will play a major role in this energy transition by decarbonizing existing and new fossil fuel power plants and the production of low-carbon fossil-fuel-based blue hydrogen. Blue hydrogen can be used for hydrogen fuel cell mobility in the transport sector and heat and feedstock in the industry sector. Current estimates show that there is adequate CO2 storage capacity in the world’s saline aquifers and oil and gas reservoirs to store 2 centuries of anthropogenic CO2 emission. However, the slow pace of CCS implementation is concerning and is due, in part, to too low of an oil price to make CO2-enhanced oil recovery profitable, lack of financial incentives for CO2 geological storage, low public acceptance, lack of consistent government energy policy and CCS regulations, and high capital investment. We propose several ways to accelerate CCS implementation. Among others, they include establishing regional CCS corridors to make use of economy of scale, public CCS engagement, carbon pricing, and using public–private partnership for financing, technology transfer, and linking up different stakeholders.

Amino Acids as Kinetic Promoters for Gas Hydrate Applications: A Mini Review

“…The hydrate based hydrogen storage application is one prospect that has continually captured the attention of researchers globally and is expected to be widely investigated in the near future as society moves toward a low-carbon future. − The technology though is plagued with issues such as the extremely high pressures required for hydrate formation, the slow gas uptake rates, and the low final gas uptakes achieved. ,, Amino acids, potent kinetic hydrate promoters operating with a clean mode of operation (no foam formation), are expected to play an important role in the maturity of hydrate based hydrogen storage technology, especially when used in conjunction with a dual-function (thermodynamic and kinetic) promoter such as THF or DIOX . The kinetic promotion performance of amino acids is system dependent as has already been discussed in section , and thus, it will be extremely interesting to see if the two amino acids l -methionine and l -tryptophan that are effective kinetic promoters for both methane and carbon dioxide hydrate formation are able to show similar activity for hydrogen hydrate systems as well.…”

China’s energy transitions for carbon neutrality: challenges and opportunities

“…The low-carbon transition of energy systems is imperative to achieve the goal. Carbon neutrality can be realized by reducing CO 2 emissions directly by reducing consumption of traditional fossil fuels and offsetting CO 2 emissions by negative emissions produced by bioenergy, in conjunction with carbon capture, utilization, and storage (CCUS), and direct air capture of CO 2 with storage [ 29 , 30 ]. There are a lot of pathways for energy transitions involving different rates of change, different aspects of the transformation of the energy system and many uncertainties.…”

Growth Mechanism of Micro/Nano Metal Dendrites and Cumulative Strategies for Countering Its Impacts in Metal Ion Batteries: A Review

“…For better coulombic efficiency, a tinny film of aluminum oxide was kept on the hard carbon surface. Mxenes and plastic wastes have greater recycling viability and utilization potential for energy storage in the coming years [461][462][463][464][465]. Likewise, battery recycling may improve the secondary life with reduced material requirements in batteries.…”
