Drax has announced that it is to pilot the first bioenergy carbon capture storage (BECCS) project of its kind in Europe, which, if successful, could make the renewable electricity produced at its North Yorkshire power station carbon negative.
BECCS is vital to global efforts to combat climate change because the technology will mean the gases that cause global warning can be removed from the atmosphere at the same time as electricity is produced. This means power generation would no longer contribute to climate change, but would start to reduce the carbon accumulating in the atmosphere.
The demonstration project will see Drax partner with Leeds-based C-Capture and invest £400,000 in what could be the first of several pilot projects undertaken at Drax to deliver a rapid, lower cost demonstration of BECCS.
Drax Power Station became the largest decarbonisation project in Europe by upgrading its existing facilities and, if the pilot is successful, it will examine options for a similar re-purposing of existing infrastructure to deliver more carbon savings.
A report by the Energy Technology Institute in 2016 has suggested that by the 2050s BECCS could deliver roughly 55 million tonnes of net negative emissions a year in the UK – approximately half the nation’s emissions target.
The first phase of the project, starting this month, will look to see if the solvent C-Capture has developed is compatible with the biomass flue gas at Drax Power Station.
A lab-scale study into the feasibility of re-utilising the flue gas desulphurisation (FGD) absorbers at the power station will also be carried out to assess potential capture rates.
FGD equipment is vital for reducing sulphur emissions from coal, but has become redundant on three of the generating units at Drax that have been upgraded to use biomass, because the wood pellets used produce minimal levels of sulphur.
Depending on the outcome of a feasibility study, the C-Capture team will proceed to the second phase of the pilot in the autumn, when a demonstration unit will be installed to isolate the carbon dioxide produced by the biomass combustion.
Will Gardiner, CEO, Drax Group, said: “If the world is to achieve the targets agreed in Paris and pursue a cleaner future, negative emissions are a must – and BECCS is a leading technology to help achieve it.
“This pilot is the UK’s first step, but it won’t be the only one at Drax. We will soon have four operational biomass units, which provide us with a great opportunity to test different technologies that could allow Drax, the country and the world, to deliver negative emissions and start to reduce the amount of carbon dioxide in the atmosphere.”
Unlike previous CCS projects Drax has been involved with, this is an early pilot for a new technology. It will examine the potential of a new form of carbon capture, post combustion on biomass, rather than coal.
The government’s Clean Growth Strategy identified BECCS as one of several greenhouse gas removal technologies that could remove emissions from the atmosphere and help achieve long term decarbonisation.
Claire Perry, Energy & Clean Growth Minister, said: “We aim to make the UK a world leader in carbon capture usage and storage, a key part of our modern Industrial Strategy. It’s hugely exciting that Drax has chosen to invest in this innovative project, demonstrating how government support for innovation can create an environment where companies can develop new technologies and scale up investment to build the sectors we will need to achieve long term decarbonisation.”
C-Capture is a spin-out from the Department of Chemistry at the University of Leeds, established through funding from IP Group Plc.
Chris Rayner, founder of C-Capture and Professor of Organic Chemistry at the University of Leeds, said: “We have developed fundamentally new chemistry to capture CO2 and have shown that it should be suitable for capturing the carbon produced from bioenergy processes.
“The key part is now to move it from our own facilities and into the real world at Drax. Through the pilot scheme we aim to demonstrate that the technology we’ve developed is a cost-effective way to achieve one of the holy grails of CO2 emissions strategies – negative emissions in power production, which is where we believe the potential CO2 emissions reductions are likely to be the greatest.”
Andy Duley, Director of Commercialisation at the University of Leeds, said: “The University has an established track record in working with private sector investors and leveraging its own funds to launch successful spin out companies. C-Capture is the latest example of our continued success in converting research expertise into a valuable service which directly benefits industry, and has the potential to make an impact around the world.”
C-Capture has been awarded funding of over £1 million to help develop their amine free post-combustion carbon capture solvent technology for use in power generation.
The funding is from the Department for Business, Energy and Industrial Strategy under their Energy Entrepreneurs program, and the CO2 Capture Project (funded by BP, Chevron and Petrobras). The project, working with industrial collaborators, and with world-leading experts in CCS from Sintef in Norway, aims to facilitate scale up of C-Capture technology, focussing on key aspects of relevance for large scale deployment. In particular, it aims to verify the exceptional low energy requirements for CO2 capture, other environmentally beneficial aspects, and to provide an overall understanding of the main benefits compared to other current solvent based approaches for CO2 capture.
We are pleased to announce the appointment of Tristan Fischer as Executive Chairman of the C-Capture Board. Tristan joins us with over 20 years experience in energy infrastructure projects, with a focus on low carbon and renewable energy.
He brings a wealth of experience from previous positions as CEO, Chairman and/or Director of a number of private and public companies. Previous companies include Camco, where he provided energy efficiency solutions for the coal, steel and cement sectors, Shell Renewables Hydrogen & CO2 and Shell Technology Ventures, where he had multiple roles, and Citigroup Project Finance, where he financed coal, natural gas and IGCC power stations.
Prof. Chris Rayner, Founder Director of C-Capture commented, ‘The appointment of Tristan to the Board represents a major milestone in the maturation of C-Capture as we progress to commercialisation of our technology. We are very excited about his appointment and look forward to working with him at this vital stage of the company development.’
Tristan Fischer commented, ‘I am particularly excited about the prospect of working with such an innovative and enthusiastic group of people. The C-Capture technology is a major improvement over current processes for CO2 removal, and the broad range of potential applications represents a tremendous opportunity as we make the transition to a low carbon world.’
C-Capture has been co-funded by Innovate UK, the UK’s innovation agency to help develop their Biogas units for Anaerobic Digestion (AD) and landfill gas upgrading. The project started in late 2017 to develop lower cost process units for removing CO2 from methane gas streams using the proprietary C-Capture solvent. Such upgrading of biogas is very important to increase the methane content to levels suitable for renewable energy applications, including electricity generation, as a transport fuel and for injection into the gas grid (C-Capture Gas Sweeting Unit).
C-Capture exhibits at ADBA’s Biomethane & Gas Vehicle Conference on 27th September 2017 in Queen’s Hotel, Leeds to engage with members of the AD industry and explore the opportunities and challenges associated with the use of biomethane as a low-cost renewable transport fuel.
