The use of liquid organic hydrogen carriers (LOHC) is an alternative to transporting hydrogen without the need for pipeline infrastructure or hydrogen liquefaction. Instead, organic materials are hydrogenated at the hydrogen production source, transported to their destination, and dehydrogenated to release the hydrogen for use. The bulk transportation of organic liquids is commonplace, relatively low cost, and well established, thus simplifying the movement of hydrogen via LOHC. With the growing demand for green hydrogen to support decarbonization efforts worldwide, LOHC is emerging as a practical means of transporting hydrogen from production sites to consumption sites. This report provides an overview of LOHC technologies. The report also includes a technology readiness level (TRL) summary of LOHC options, carbon intensity analysis, and discussion related to the cost of transporting hydrogen for various LOHC types. Comparisons with other hydrogen transportation options such as liquefied hydrogen and ammonia are also presented.

This report provides a comprehensive analysis of the tire industry's shift towards sustainability, covering the background, objectives, and scope of sustainable practices in tire manufacturing, including the economics, carbon intensity, and environmental impacts of key materials and the exploration of sustainable alternatives. It covers green tire technology, examining bio-based rubber innovations, the application of nanotechnology, and sustainable material replacements, with a forward-looking perspective on future green tire technologies. Additionally, the report discusses recycling and end-of-life management for tires, emphasizing the significance of recycling, various recycling processes, and associated environmental, health, and safety considerations. The economic analysis explores the financial aspects of green tire production and recycling, including cost, pricing, and regional economic impacts. Environmental impacts and sustainability practices are scrutinized through Scope 1 and Scope 2 carbon intensity comparisons and sustainable manufacturing best practices. The report also identifies the interests of key stakeholders in the green tire industry, including manufacturers, suppliers, regulatory bodies, consumers, and environmental groups, underlining the comprehensive approach to fostering sustainability in tire manufacturing and usage.

The 2023 Cost Curve Analysis model for Methyl Methacrylate (MMA) combines NexantECA’s global plant capacity database and views on supply and demand with an extensive cost of production database and NexantECA’s annual price forecasts developed for three oil scenarios. Delivered as an interactive spreadsheet, the model offers views of historical MMA cost competitiveness and forecast cost competitiveness and profitability on an annual basis.

This report investigates the various commercial and developmental routes for the production of renewable ethylene. Technologies based on bio-ethanol, bio-naphtha, and bio-methanol are investigated for ethylene production, as well as sugar and glycerin-based routes directly to ethylene glycol. Pyrolysis oil from thermal conversion of plastic wastes has seen significant development for conversion into bio-naphtha feedstock, as well as gasification of biomass to produce methanol for ethylene production. Dry reforming of methane with carbon dioxide and electrochemical production of ethylene are the new technologies covered in this edition of the report. Cost of production models, process descriptions, capacity analysis and implications for the conventional industry are included.
