Update techno-economic benchmarks for fossil fuel-fired power plants with CO₂ capture

1 July 2020
Capture
Costs of CCUS

IEAGHG updates its techno-economic studies periodically to examine the impact of developments and improvements made to core components, of changes made to system design, or when the fiscal environment may have materially altered. In the present case, benchmarks were updated for both coal-fired and natural gas-fired power plants with CCS, primarily to: Investigate the techno-economic impact of markedly increasing the capture rates to achieve near-zero CO₂ emissions; And then, in addition, to: Explore the technological and economic benefits of recent improvements that may have been made to ultra-supercritical pulverised coal (USC PC) and natural-gas combined cycle (NGCC) technologies; and Examine the benefits of flue gas recirculation in the natural gas-fired cases, and the trade-offs between efficiency and flexibility in the coal-fired cases. Benchmarks were updated against a study published in 20181, where prices were based on 3Q2016. The update study used 3Q2018 prices.

The Clean Refinery and the Role of Electricity Generation

1 May 2020
Capture

The oil refinery sector faces significant challenges in response to the Paris Agreement’s 2050 projections for carbon emission reductions. Moreover, there is a global trend to process significant amounts of heavy, sour crude to produce high value products, such as ultra-low-sulphur diesel and gasoline, to achieve better refinery margins as well as meeting stringent environmental standards including green-house gas emission reductions. The option of CO₂ emission free electricity generation within refineries can help to meet these goals. The primary aim of this study was to explore the role of the ‘clean refinery’ concept and how it could contribute to the Paris Agreement’s long-term objective to curb peak global greenhouse gas emissions. Various options for refineries are available depending, not only on the complexity and degree of integration, but also on whether a refinery already exists or is still at the planning stage. In addition to these general considerations, the regional location, crude mix and local markets for refined products and electricity all influence the design, complexity and economic viability of ‘clean refineries’. p>

Agenda Workshop on Hydrogen Production with CCS

21 February 2020
Capture
Event Proceedings

Hydrogen is a key raw material to other energy intensive industries. Globally, nearly 90% of the hydrogen produced industrially is consumed by the ammonia, methanol and oil refining industries. Moreover, hydrogen could soon play a significant role in the decarbonisation of power, space heating (i.e. industrial, commercial, building and residential heating) and transport fuel (i.e. use of fuel cell vehicles). Although the steam methane reformer route (SMR) is the leading technology for H2 production from natural gas or light hydrocarbons, there are other mature and emerging alternatives. Similarly, while increasing the process efficiency has shown a CO₂ emissions reduction of nearly 10%, CCS has been identified as a key strategy to cut down CO₂ emissions from hydrogen production. Against this background the Carbon Sequestration Leadership Forum (CSLF) decided to map activities on hydrogen production with CCS in member states and elsewhere. One conclusion of that exercise was to hold workshop with other organisations. A steering committee was formed to organise this workshop, held on November 6th 2019, and hosted by EDF and Club CO₂. This workshop was held for one day, devoted to a plenary session addressing three general topics, and including 90 attendees from 19 countries. Each session included several invited presentations, followed by a discussion among the workshop attendees. This document presents brief summaries of the three plenary sessions topics and one break-out session where all attendees were able to contribute.

CO₂stCap (Cutting Cost of CO₂ Capture in Process Industry)

Costs of CCUS

The CO₂StCap project (Cutting Cost of CO₂ Capture in Process Industry), led by SINTEF, was a research initiative (2015-2019) funded by the Norwegian CLIMIT-Demo programme via Gassnova and the Swedish Energy Agency. The CO₂StCap research partners were SINTEF, the University of South-Eastern Norway, Chalmers University of Technology, RISE, and Swerim AB. The industries involved were SSAB, Elkem AS, Norcem Brevik AS, and AGA Gas AB. IEAGHG and GCCSI supported the project. The CO₂StCap project investigated CO₂ partial capture configurations for cement, pulp and paper, steel, and silicon for solar cells industries. The CO₂ capture technology investigated in this project was a MEA-based chemical absorption system, which includes an optimized rich-solvent splitting and absorber inter-stage cooling. The capture rates considered are dependent on the inputs of the specific cases, such as plant characteristics, CO2 stacks, CO2 concentration in the flue-gas to be treated, and supply of heat/energy. The CO₂StCap project contained a transparent cost assessment, which includes the capital and operational expenditures (CAPEX and OPEX) for retrofitting cases. The main cost metric used in this study is the CO₂ capture cost (€/tonne of CO₂ captured) and the main elements are described in detail. Steam generation for the CO₂ capture system was identified as a key cost element. The steam sources investigated were: steam produced from the excess heat; from a new boiler; and from a low-pressure bleed from existing steam cycles. Other key cost elements identified in this study are the plant lifetime and rate of return. The CO₂StCap project also investigated the use of biomass in different sectors and hydrogen in the steel industry.

Costs of CCUS

Natural gas demand is forecasted to grow continuously for the next 10 years, playing a vital role in the global energy mix in 2030. in the specific case of liquefied natural gas, projections indicate a continued upward growth. The majority of near-term growth in liquefaction capacity is likely to happen in North America and Australia, although a number of other projects have the potential to add significant liquefaction capacity in the long term as well.

Towards Zero Emissions CCS from Power Stations using Higher Capture Rates or Biomass

1 March 2019
Capture

To-date, capture technology developers have largely focused on designing plant for CO₂ capture rates of 85% to 90%, leaving 10-15% of the emissions uncaptured, which are usually referred to as residual emissions. In a “well below 2°C” scenario, it is projected that net zero carbon emissions would be required by early in the second half of this century. A review of the literature indicated that there were no technical barriers to increasing capture rates in the three classic CO₂ capture routes (post-, pre- and oxyfuel combustion) and with the broad suite of CO₂-capture technologies currently available or under development. A techno-economic analysis of a standard PCC process applied to both coal- and gas-fired power plants revealed that, with dedicated process design, the additional costs of achieving essentially zero CO₂ emissions were quite modest in comparison with the costs of achieving 90% CO₂ capture. For coal-fired power stations, the analysis found that using biomass co-combustion (10% biomass) combined with a standard PCC process (90% CO₂ capture) was the lowest cost option.
