Branched Diol Monomers from the Sequential Hydrogenation of Renewable Carboxylic Acids
A prominent challenge in replacing petrochemical polymers with bioderived alternatives is the efficient transformation of biomass into useful monomers. In this work, we demonstrate a practical process for the synthesis of multifunctional alcohols from five- and six-carbon acids using heterogeneous catalysts in aqueous media. Design of this process was guided by thermodynamic calculations, which ...

The Motorship: Ammonia could be the answer to Shipping’s Hydrogen Challenge
There are already plans on the table to create green, carbon-free hydrogen from renewables, so the maritime industry has begun its search for the next step, one which would allow H2 to be turned into a more easily storable, transportable form of fuel. Ammonia could be the answer, writes Stevie Knight. Surprisingly, ammonia’s volumetric energy density is higher than liquefied hydrogen, says ...

Biohydrogen production by anaerobic co–digestion of press mud and domestic sewage
Anaerobic fermentation of press mud and sewage for biohydrogen production was conducted in six batch reactors for various total solid concentrations between 5–8.5%. Chemical oxygen demand, pH, total solid % for biohydrogen produced were monitored regularly. The experiments were conducted for 40 days to optimise the total solid content of the feed for maximum biohydrogen production. Effect of ...

Fuel Cells Can Decarbonize California’s Buildings (While Keeping the Lights On)
California just faced historic blackouts. In fact, it endured three of the largest planned power outages in state history. The era of intentionally cutting off power to residents and businesses across the state to prevent wildfires – known as Public Safety Power Shutoffs (PSPS) – has arrived, and it’s highlighting the urgent need for energy solutions that address both the causes ...

A combined graph theory and analytic hierarchy process approach for multicriteria evaluation of hydrogen energy systems
Hydrogen is a renewable energy source and has the potential to mitigate the green house gas effect and to meet the increasing global electricity demand. In the present study, a multicriteria methodology is developed by combining graph theory and analytic hierarchy process methods for the evaluation and selection of hydrogen energy systems. The hydrogen energy system alternatives are assessed ...

Producing Green Hydrogen with Renewable Electricity
Hydrogen is an essential component of fuel cells. Sure, we all know that. However, did you know that all types of the gas are not created equally? Green hydrogen has gained a lot of momentum in renewable circles today. Hydrogen is produced by electrolyzing water. The process involves passing an electric current through water (under regulated conditions) to break its chemical composition. A ...

Combating global warming via non-fossil fuel energy options
Non-fossil fuel energy options can help reduce or eliminate the emissions of greenhouse gases and are needed to combat climate change. Three distinct ways in which non-fossil fuel options can be used in society are examined here: the capture/production of non-fossil fuel energy sources, their conversion into appropriate energy carriers and increased efficiency throughout the life cycle. ...

For the Green Deal, hydrogen also needs to be green
The new European Commission is planning a European Green Deal. The goal is to create the first climate-neutral continent by 2050. This cannot happen without using much more hydrogen than at the moment because hydrogen is a zero-emission fuel when burned with oxygen. However, not all forms of hydrogen are alike. We need to shift from grey hydrogen, the production of which causes CO₂ ...
