Jenbacher engines drive sector coupling at US landfill
Raven SR has announced plans to use INNIO’s Jenbacher engines with a “ready for H2
” option
to produce renewable power. The engines will power and heat Raven SR’s S-Series hydrogen production facility at a landfill in Richmond, California (pictured). At the site, landfill gas (LFG) will be the primary fuel to provide power for the
non-combustion process that is being used to convert waste to hydrogen. The hydrogen product will be resold to power fuel cells in heavy-duty trucks. The Raven SR process will also provide a residual fuel containing residual green hydrogen from the concentration process to supplement the LFG to fuel the Jenbacher engines to generate renewable power in a continuous loop. The use of the engines in conjunction with Raven’s technology offers a promising renewable hydrogen alternative to electrolysis, using less electricity and no need for fresh water. The Jenbacher engines will allow the Raven facility to generate a significant amount of its own electricity. This is “a milestone in the interconnecting of transportation and industry with the power producing sector,” commented Dr Olaf Berlien, president and CEO of INNIO. “This project produces onsite renewable hydrogen from waste, uses a blend of hydrogen to generate electricity to power operations, and provides renewable
Waste-to-H2
Maire Tecnimont has announced that its subsidiary NextChem has been assigned a €194 million grant for the development of a waste-to- hydrogen plant as part of the EU funded “IPCEI Hy2Use” project. The project entails the setting up of a “hydrogen valley” in Rome, an industrial- scale hub for the development of a supply chain for the production, transport, storage and use of hydrogen for the decarbonisation of industrial processes and for achieving sustainable mobility.
hydrogen for the transportation industry. This is a model example of how innovation can enable sector coupling which will be critical on the global path to net zero.”
“INNIO is able to meet our delivery schedule and provide engines that are compliant with emissions requirements for a blend of CO2
,
methane and hydrogen,” said Matt Murdock, CEO of Raven SR. “The Jenbacher engines are a very important element for us to realise our objective of producing renewable hydrogen with our non- combustion steam/CO2
reformation process,
independent of the grid” and the escalating “energy and electricity crisis” requires that “we generate autonomous power onsite.” Raven SR plans to bring its S-Series online in the first quarter of 2023 at the Republic Services West Contra Costa Sanitary Landfill in Richmond, California. This project will initially process up to 99.9 tons of organic waste per day and produce up to 2000 metric tons per year of hydrogen.
in Rome’s hydrogen valley
The grant will be disbursed during the construction phases of the plant. The next steps are focused on the start of project activities and permitting, with the aim of achieving plant start- up in the first half of 2027, in compliance with the funding conditions.
In the initial phase production of 1500 t/ year of hydrogen and 55000 t/year of ethanol is expected. The production of hydrogen will grow according to demand, up to 20 000 t/year, with a corresponding reduction in ethanol prioduction.
Employing NextChem’s proprietary technology, developed by its subsidiary MyRechemical, the waste-to-hydrogen plant is expected to process 200 000 t/year of non-recyclable solid waste. The European project also includes a contribution of approximately €4 million for additional research and development activities in waste-to-hydrogen technology, leveraging scientific partners such as Enea, Fondazione Bruno Kessler and La Sapienza University of Rome.
Doosan Skoda finds sweet spot on La Réunion
The world is getting cleaner, but steam turbines still have their place, so says Pilsen based Doosan Skoda Power, reporting a recent contract placed by Paris-based Albioma (now 92.19% owned by KKR) to supply two turbines to a biomass fuelled power plant on the island of La Réunion (pictured below right).
The power plant, previously coal fired, burns waste material from the processing of sugar cane, providing process steam to the sugar production process, as well as electricity. The Czech steam turbine manufacturer is supplying two 30 MW steam turbines, each with two inlets and controlled extractions, together with gearboxes and generators.
Because of the isolated island grid and the necessity of continuous production, very high levels of reliability and efficiency were specified.

La Réunion is a destination for tourism but also a hub for sugar production, with seasonal harvesting coinciding with peak power demand of the island. Stability of the grid has to be maintained throughout.
“This is an important project for Doosan Skoda Power,” said Michal Sarpong, the company’s area sales director, requiring us
to install two sets of turbines into an existing machine hall on a tight schedule and with the necessity of entailing minimum modifications to the existing building.
Doosan describes the need for a stable steam demand at given temperatures and pressures over a 24 h production cycle as a “sweet spot” for its steam turbines.
