Type of post: NEWS IN BRIEF.

Chevron U.S.A. Inc (subsidiary of Chevron Corporation) and California Bioenergy LLC (CalBio, company which designs, develops, operates and finances digester projects) have announced a joint investment in a holding company (CalBioGas LLC) with dairy farmers to produce and market biomethane as a vehicle fuel in California.
Press release: “CalBio & Dairy Farmers Partner with Chevron on Dairy Biomethane Fuel Projects”, 18/6/2019.

Figure 1. Stockdale dairy (taken from the website of the company). This CalBio project is a 600 kW facility located outside of Bakersfield. It was one of the first double-lined covered lagoon digester’s in California.

Chevron has signed an agreement to provide funding for as many as 18 digesters across three geographic clusters in Kern, Tulare and Kings counties (San Joaquin Valley, California). The clusters of digesters have been awarded California Department of Food and Agriculture grants, which must be augmented with additional capital to complete the projects. CalBio brings the technology, the operational experience and the capital to help dairy farmers build digesters and capture systems to convert the methane released on manure storage into renewable natural gas (RNG).

The projects are designed to send biogas to a centralized processing facility where it will be upgraded to RNG and injected into the local gas utility’s pipeline. The RNG is then marketed as an alternative fuel for heavy-duty trucks, buses and farm equipment.

El cultivo de microalgas no es algo novedoso, muchos de los métodos y conceptos que se usan hoy en día fueron desarrollados a finales del siglo XIX y principios de la pasada centuria. En décadas posteriores, se han ido refinando por la intervención de varias disciplinas que han trabajado de manera conjunta: biología, ingeniería de procesos, matemáticas y física. En los últimos 30 años, la industria biotecnológica de las microalgas ha crecido y se ha diversificado de manera significativa. Sin embargo, las aplicaciones comerciales existentes, todavía se hallan limitadas a comercios de bajo volumen y gran valor añadido como el de los suplementos alimenticios o el de los extractos (por ejemplo, el beta-caroteno). De acuerdo con un informe de IEA Bioenergy del 2010, la cantidad de biomasa algal producida comercialmente estaba en el entorno de las 9.000 toneladas. 1,2,3,4 Actualmente, el interés creciente que despiertan el empleo de las microalgas en la obtención de biocombustibles y e

Versión en Español Type of post: NEWS IN BRIEF. Royal Dutch Shell plc (Shell) has announced a final investment decision to build a biofuels facility with a capacity of 820 ktons/year at the Shell Energy and Chemicals Park Rotterdam (the Netherlands) formerly known as the Pernis refinery. Once built, the facility will be among the biggest in Europe to produce sustainable aviation fuel (SAF) and renewable diesel made from waste. Press release: “ Shell to build one of Europe’s biggest biofuels facilities ”, 16/09/2021. Figure 1. Pernis refinery Advanced production methods will be used to make the fuels. The facility is expected to use technology to capture carbon emissions from the manufacturing process and store them in an empty gas field beneath the North Sea through the Porthos project. A final investment decision for Porthos is expected next year. A facility of this size could produce enough renewable diesel to avoid 2.8 Mtons of carbon dioxide emissions a year. The Rotterd

Traditionally, diesel components produced from vegetable oils are made by an esterification process. In fact, HVO are commonly referred to as renewable diesel or green diesel in order to distinguish from Fatty Acid Methyl Esters (FAME), best known as biodiesel. Other acronyms are also used depending on the feedstock, such as Rape Seed Methyl Ester” (RME), “Soybean Methyl Ester” (SME), “Palm Oil Methyl Ester” (PME) or “Used Cooking Oils Methyl Ester (UCOME). In the HVO production process, hydrogen is used to remove the oxygen from the triglycerides and does not produce any glycerol as a side product. Additi
