Steeper Energy will build a demo plant in Calgary to transform biowastes into advanced fuels

By -

Type of post: NEWS IN BRIEF.

The City of Calgary and Steeper Energy Canada Ltd. (Steeper Energy) have announced a new cooperation agreement regarding the future transformation of Calgary’s sewage sludge and other urban generated biowastes for the production of sustainable biofuels such as renewable diesel or jet fuel.
Press release: “Memorandum of Understanding signed by the City of Calgary with Steeper Energy Canada Ltd.”, 2/7/2020.

Steeper Energy is a Danish-Canadian clean-fuel company focused on commercializing their proprietary Hydrofaction™ technology, an implementation of hydrothermal liquefaction which applies supercritical water as a reaction medium for the conversion of biomass directly into a high-energy density renewable crude oil, referred to as Hydrofaction™ Oil. The process converts biowastes (including sewage sludge, food or forestry wastes) into renewable biofuels. In addition to biofuel production, the process converts and eliminates wastewater contaminants such as microplastics and pharmaceuticals and isolates heavy metals. Hydrofaction® allows also for the capture of beneficial nutrients such as phosphorus and nitrogen, which can later be made available as fertilizer for farmers. Currently, the company is building a first pilot plant in Denmark.

The MoU formalizes the intent of The City of Calgary and Steeper Energy to see the development of a demonstration plant at the Pine Creek Wastewater Treatment Plant in South-East Calgary. The City has agreed to host Steeper Energy at its state-of-the-art wastewater treatment plant, as well as to supply a small portion of Calgary’s primary and secondary sewage sludge to produce advanced biofuels. Upon concluding final arrangements with Calgary and the approval from Steeper’s board of directors, the project could break ground in early 2021.

Biofuels from algae

In my opinion, the production of biofuels and biobased chemicals from algae is one of the most fascinating topics in the sector of the biorefineries and it will be one of the niches of opportunity with highest potential in the medium and the long terms. This post pretend to be a very basic approach to the topic Algae-to-Biofuels through three general key points. Algae 1,2,3,4,5 Algae include a wide variety of photosynthetic organisms capable of transforming light, water and specific nutrients into products that can be used with commercial and industrial purposes. We can say that algae are sunlight-driven factories with potential to convert CO 2 into biofuels, high-value biochemical, food and feed. There are four algae cultivation technologies currently in use for commercial algae cultivation and proposed for algal biofuel production: extensive or open ponds, intensive or raceway ponds, closed photobioreactors in many designs and closed fermenter systems.

Clave del proceso: Tratamiento con hidrógeno. En el proceso de producción de HVO, el hidrógeno se usa para eliminar el oxígeno de los triglicéridos produciendo una mezcla de parafinas lineales, CO 2 y agua. Posteriormente, el producto de la primera etapa se isomeriza, siempre en presencia de hidrógeno, para ramificar las cadenas lineales con el propósito de mejorar las propiedades de flujo en frío de los productos finales. Por tanto, los HVO son

Fecha de publicación: 16/11/2015 Última actualización: 20/02/2016 Descripción 1,2 El ácido levulínico (también conocido como ácido 4-oxopentanoico o ácido γ-cetovalérico) es un compuesto orgánico con fórmula química C 5 H 8 O 3 . Es un sólido cristalino soluble en agua y en disolventes orgánicos polares. Contiene un grupo cetona y un grupo carboxilo cuya presencia posibilita patrones reactivos interesantes. Es uno de los “ Biobased Chemical Building Blocks ” más reconocidos, precursor de un amplio número de compuestos (véase el apartado Aplicaciones más abajo). De hecho, fue reconocido por el DoE como una de las principales moléculas plataforma del futuro y puede cubrir de manera eficaz muchas de las atribuciones de productos químicos y materiales procedentes del petróleo. Tecnologías de proceso 1,3,4,5 La degradación controlada de azúcares C6 mediante ácidos es el proceso más usado para preparar ácido levulínico a partir de biomasa lignocelulósica. Se han estu

Publication date: 15/06/2017 Last update: 24/01/2018 Introduction 1,2,3,4,5 2,5-Furandicarboxylic acid (FDCA), also known as dehydromucic acid and pyromucic acid, is an organic compound that was first detected in human urine. In fact, a healthy human produces 3-5 mg/day. It is a very stable compound. Some of its physical properties, such as insolubility in most of common solvents and a very high melting point (it melts at 342 °C), seem to indicate intermolecular hydrogen bonding. FDCA has two carboxylic acid groups, which makes it a suitable monomer for polycondensation reactions with diols or diamines. It is one of the top 12 value-added biobased chemicals listed by the US DoE in 2004. The list was updated in 2010 and FDCA was included again, but this time in a group together with furfural and 5-hydroxymethylfurfural (5-HMF). Those three molecules are the main representatives of the furanics (furan derivatives) that has been referred to as “Sleeping Giants” beca
