Euro46m of the funding came from consortium partners while Euro38m came from a UK Research and Innovation (UKRI) Industrial Decarbonisation Challenge grant.
Hanson chief executive officer Simon Willis said, “Today’s funding announcement is fantastic news for everyone involved in HyNet North West. Cutting CO2 emissions is a key priority for us, and we are excited to be one of the first UK cement producers working on carbon capture and storage (CCS) as part of this collaborative project.” He added, “We’ve taken big steps towards reducing carbon emissions and have set ourselves an ambitious target of achieving a 50% reduction in CO2 emissions by 2030, based on 1990 levels, and net zero carbon concrete by 2050. CCS at cement plants is a key part of our roadmap to net zero.”
UltraTech receives Science-Based Targets Initiative validation for emissions reduction targets
12 March 2021India: The Science-Based Targets Initiative (SBTI) has validated UltraTech Cement’s CO2 emissions reduction targets. The validation confirms that the company’s targets are in line with a 2°C temperature rise scenario under the Paris Agreement. The targets consist of a 27% reduction in Scope 1 CO2 emissions between 2017 and 2032 and a 69% reduction in Scope 2 CO2 emissions between 2017 and 2032. This corresponds to a 462kg/t net CO2 reduction for the producer’s cement.
Managing director Kailash Jhanwar said, “A changing climate scenario poses significant challenges for the built environment sector. It equally provides valuable opportunities to develop sustainable products and services. By committing to science-based targets, UltraTech Cement has once again demonstrated leadership in paving the way for the sector to help build sustainable infrastructure.”
Lehigh Hanson and Fortera to install carbon capture and storage system at Redding cement plant in California
12 March 2021US: Lehigh Hanson has signed a collaboration agreement with materials technology company Fortera. Under the agreement, the companies will establish a carbon capture and storage (CCS) system at the producer’s 0.8Mt/yr integrated Redding Cement plant in Shasta district, California. The system will produce a cementitious material for use in concrete production. The material will be the first of its kind to be produced at a cement plant.
"This collaboration with Lehigh Hanson will prove the commercial scalability, the quality of the final product, and the competitive economics of the Fortera process," said Ryan Gilliam, chief executive officer and co-founder of Fortera. He added that the Fortera process (ReCarb) has been designed to utilise the existing cement infrastructure, from the quarry to the kiln, but with less CO2 emissions, lower energy, and lower processing temperatures, leading to 60% lower CO2 emissions per tonne of product.
Sika develops CO2-binding concrete recycling process
11 March 2021Switzerland: Sika has developed ReCO2ver, a process which produces limestone, sand and gravel from the combination of concrete and CO2 with an additive developed by the supplier. The process enables demolition companies to completely recycle used concrete, while storing captured CO2 at a rate of 60kg/t of crushed concrete. The materials produced can be used as aggregates to make concrete of comparable strength to an all-new product.
Chief executive officer Paul Schuler said, "The five largest European Union countries alone generate roughly 300Mt/yr of old concrete. With complete recycling of these materials, up to 15Mt/yr of CO2 emissions can be stored. We are convinced that our new process has the potential to benefit both our customers and the environment."
Hanson’s Padeswood cement plant to host Hynet North West consortium carbon capture and storage study
01 March 2021UK: HeidelbergCement subsidiary Hanson has partnered with the Hynet North West consortium for a study on carbon capture and storage (CCS) solution at its Padeswood, Flintshire, cement plant. The consortium is planning to implement carbon capture and storage installations at industrial facilities across Flintshire, Wrexham, Cheshire, Merseyside, Greater Manchester and Lancashire. It says that when active the network will constitute the world’s first low carbon industrial cluster, with a total reduction of 10Mt/yr of emissions by CCS. The Padeswood plant would account for 800,000t/yr of this total.
Hanson group chief executive officer Simon Willis said, “Our involvement in the HyNet North West project is the latest example of our commitment to cutting CO2 emissions. CCS at our cement plants will be a key part of our roadmap to achieve net zero carbon by 2050. The first step would be for us to carry out a feasibility study - this would give us a clear design basis and cost estimate for a capture plant and connection to the planned HyNet North West CO2 network and storage system.”
The HyNet North West project also includes production, storage and distribution of low carbon hydrogen, which will help to decarbonise other industries whose CO2 emissions primarily come from fossil fuels. The project, led by Progressive Energy, is being developed by a consortium of regionally located partners including Cadent, CF Fertilisers, Eni UK, Essar, INOVYN and the University of Chester as well as Hanson.
