Santos is actively working to reduce its carbon footprint and prepare for a lower-carbon future, including promoting the role of gas in this future. Santos has set a long-term aspiration to achieve net-zero emissions from its operations by 2050, and a target to reduce emissions across existing operations in the Cooper Basin and Queensland by 5% by 2025. The Energy Solutions team was created to support the delivery of these objectives. Energy Solutions completed a global technology review to identify technologies that would reduce emissions across Santos’ operations and grow gas demand. The review resulted in focus areas of solar, storage (battery, gas and other media), waste heat recovery, wind, carbon capture and storage (CCS) and solar thermal. Santos progressed to implementation and successful demonstration of emissions reduction in 2018 with a world-first installation of an autonomous solar- and battery-powered beam pump. The initial installation in the Cooper Basin is now being expanded to 56 pump conversions to solar and battery with the support of the Australian Renewable Energy Agency. Following this success, Santos increased scale with installation of a 2.12-MW solar array and associated infrastructure at the Port Bonython processing facility. In parallel, fuel efficiency opportunities were targeted through key equipment upgrades, including power generation at Devil Creek with new reciprocating gas engines and rationalisation of legacy compression and power generation infrastructure across the Cooper Basin. Another key focus of the team is the progression of CCS, with appraisal of reservoir targets and pre-front-end engineering design (FEED) studies completed in 2019. The success of these projects provides a robust platform to support the further and more complex emissions reduction project opportunities across Santos’ operations.

Carbon capture and storage (CCS) is essential for meeting the Paris agreement global emissions targets – all identified pathways to net zero 2050 emissions require large scale deployment of CCS. The Moomba CCS project is an example of the type of projects that the oil and gas industry can undertake in Australia and globally to reduce emissions and create new business opportunities. The project is a CO2 capture, transport and storage project in the Cooper Basin with the aim of delivering material emissions reduction of 1.7 mtpa CO2-e. The project utilises existing and new infrastructure as well as depleted hydrocarbon fields to capture, compress, dehydrate and store CO2 that is currently vented. This study will provide an overview of this project including the technical challenges that were overcome to enable project success.

Abstract Today gas turbines and combined cycle power plants play an important role in power generation and in the light of increasing energy demand, their role is expected to grow alongside renewables. In addition, the volatility of renewables in generating and dispatching power entails a new focus on electricity security. This reinforces the importance of gas turbines in guaranteeing grid reliability by compensating for the intermittency of renewables. In order to achieve the Paris Agreement’s goals, power generation must be decarbonized. This is where hydrogen produced from renewables or with CCS (Carbon Capture and Storage) comes into play, allowing totally CO2-free combustion. Hydrogen features the unique capability to store energy for medium to long storage cycles and hence could be used to alleviate seasonal variations of renewable power generation. The importance of hydrogen for future power generation is expected to increase due to several factors: the push for CO2-free energy production is calling for various options, all resulting in the necessity of a broader fuel flexibility, in particular accommodating hydrogen as a future fuel feeding gas turbines and combined cycle power plants. Hydrogen from methane reforming is pursued, with particular interest within energy scenarios linked with carbon capture and storage, while the increased share of renewables requires the storage of energy for which hydrogen is the best candidate. Compared to natural gas the main challenge of hydrogen combustion is its increased reactivity resulting in a decrease of engine performance for conventional premix combustion systems. The sequential combustion technology used within Ansaldo Energia’s GT36 and GT26 gas turbines provides for extra freedom in optimizing the operation concept. This sequential combustion technology enables low emission combustion at high temperatures with particularly high fuel flexibility thanks to the complementarity between its first stage, stabilized by flame propagation and its second (sequential) stage, stabilized by auto-ignition. With this concept, gas turbines are envisaged to be able to provide reliable, dispatchable, CO2-free electric power. In this paper, an overview of hydrogen production (grey, blue, and green hydrogen), transport and storage are presented targeting a CO2-free energy system based on gas turbines. A detailed description of the test infrastructure, handling of highly reactive fuels is given with specific aspects of the large amounts of hydrogen used for the full engine pressure tests. Based on the results discussed at last year’s Turbo Expo (Bothien et al. GT2019-90798), further high pressure test results are reported, demonstrating how sequential combustion with novel operational concepts is able to achieve the lowest emissions, highest fuel and operational flexibility, for very high combustor exit temperatures (H-class) with unprecedented hydrogen contents.

In order to protect the environment, save energy and reduce emissions, and promote the utilization of wave energy, this paper reviews the development history of application generation technology, summarizes its development from two aspects of optimization and application of wave energy conversion devices, analyses the application examples of wave energy generation devices on ships. This paper summarizes the application trend of wave power generation devices on ships: wave power generation should be used as auxiliary and domestic electricity for ships and wave energy should be combined with other new energy sources. Wave energy application in marine power generation can effectively reduce emissions from ships, which is conducive to the sustainable development of human society. The system mainly included low speed marine main diesel engine, waste heat boiler, electricity generation sub-system of power turbine, electricity generation sub-system of steam turbine, the heat exchange equipment, electricity generation sub-system of organic working medium steam turbine and other equipments. Based on experimental data of main engine and later theoretical calculation, this paper studied the effect rules of electricity generation power, waste heat utilization potential and related parameters of the waste heat utilization system under different main diesel load and ambient temperature.

The Cost

Carbon mitigation is a major aim of the power-generation regulation. Renewable energy sources for electricity are essential to design a future low-carbon mix. In this work, financial Modern Portfolio Theory (MPT) is implemented to optimize the power-generation technologies portfolio. We include technological and environmental restrictions in the model. The optimization is carried out in two stages. Firstly, we minimize the cost and risk of the generation portfolio, and afterwards, we minimize its emission factor and risk. By combining these two results, we are able to draw an area which can be considered analogous to the Capital Market Line (CML) used by the Capital Asset Pricing model (CAPM). This area delimits the set of long-term power-generation portfolios that can be selected to achieve a progressive decarbonisation of the mix. This work confirms the relevant role of small hydro, offshore wind, and large hydro as preferential technologies in efficient portfolios. It is necessary to include all available renewable technologies in order to reduce the cost and the risk of the portfolio, benefiting from the diversification effect. Additionally, carbon capture and storage technologies must be available and deployed if fossil fuel technologies remain in the portfolio in a low-carbon approach.

In this work, a technical, economic and environmental analysis concerning the use of three major power generation plant types including pulverized coal, integrated gasification combined cycle (IGCC) and natural gas combined cycle, with or without carbon dioxide (CO2) capture and storage (CCS) integration, is carried out. For the analysis, the IPP optimization software is used in which the electricity unit cost and the CO2 avoidance cost from the various candidate power generation technologies is calculated. The analysis indicates that the electricity unit cost of IGCC technology with CCS integration is the least cost option with the lowest CO2 avoidance cost of all candidate technologies with CCS integration. Further investigation concerning the effect of the loan interest rate on the economic performance of the candidate plants revealed that up to a value of loan interest of approximately 5.7%, the IGCC plant with CCS retains the lowest electricity unit cost. Above this level, the natural gas combined cycle plant with post-combustion CCS becomes more economically attractive.

Bioenergy with carbon capture and storage (BECCS) is one strategy to remove CO2 from the atmosphere. To assess the potential scale and cost of CO2 sequestration from BECCS in the US, this analysis models carbon sequestration net of supply chain emissions and costs of biomass production, delivery, power generation, and CO2 capture and sequestration in saline formations. The analysis includes two biomass supply scenarios (near-term and long-term), two biomass logistics scenarios (conventional and pelletized), and two generation technologies (pulverized combustion and integrated gasification combined cycle). Results show marginal cost per tonne CO2 (accounting for costs of electricity and CO2 emissions of reference power generation scenarios) as a function of CO2 sequestered (simulating capture of up to 90% of total CO2 sequestration potential) and associated spatial distribution of resources and generation locations for the array of scenario options. Under a near-term scenario using up to 206 million tonnes per year of biomass, up to 181 million tonnes CO2 can be sequestered annually at scenario-average costs ranging from $62 to $137 per tonne CO2; under a long-term scenario using up to 740 million tonnes per year of biomass, up to 737 million tonnes CO2 can be sequestered annually at scenario-average costs ranging from $42 to $92 per tonne CO2. These estimates of CO2 sequestration potential may be reduced if future competing demand reduces resource availability or may be increased if displaced emissions from conventional power sources are included. Results suggest there are large-scale opportunities to implement BECCS at moderate cost in the US, particularly in the Midwest, Plains States, and Texas.

Key Aspects

Abstract Synthetic ammonia from fossil energy can technically be used for power generation. Viewed as hydrocarbon utilization, it enables oil and gas industries to move towards the sustainable development of resources while minimizing their carbon footprint. We present an integrated high-level overview of this concept by highlighting the following key aspects: i) the carbon footprint of the process, ii) the necessity for carbon capture and storage (CCS), iii) power generation from fuel ammonia, and iv) market development. First, the carbon footprint was estimated based on the chemical formulas of the process, which revealed the necessity for CCS for the process to provide cleaner energy. Second, having reviewed these four key aspects, we showed that most elemental technologies comprising this new value chain have already been technically proven. Finally, we discuss and conclude with possible ways towards the commercialization of this value chain.
