Scientists Have Found a Way to Save Energy And Boil Water More Efficiently

David Nield - 16 JULY 2022

Water gets boiled a lot – whether it's a cup of tea brewing in a kitchen or a power plant generating electricity. Any improvements in the efficiency of this process will have a huge impact on the overall amount of energy used for it every day.

 

One such improvement could come with a newly developed treatment for surfaces involved in heating and evaporating water. The treatment improves two key parameters that determine the boiling process: the heat transfer coefficient (HTC) and the critical heat flux (CHF).

 

Most of the time, there's a trade-off between the two – as one improves, the other gets worse. After years of investigation, the research term behind the technique has found a way of enhancing both.

 

"Both parameters are important, but enhancing both parameters together is kind of tricky because they have intrinsic trade-off," says bioinformatics scientist Youngsup Song from the Lawrence Berkeley National Laboratory in California.

"If we have lots of bubbles on the boiling surface, that means boiling is very efficient, but if we have too many bubbles on the surface, they can coalesce together, which can form a vapor film over the boiling surface."

 

Any vapor film between the hot surface and the water introduces resistance, lowering the heat transfer efficiency and the CHF value. To get around the issue, the researchers devised three different kinds of surface modification.

 

First, a series of microscale tubes are added. This array of 10-micrometer-wide tubes, spaced about 2 millimeters apart, controls bubble formation and keeps the bubbles pinned to the cavities. That prevents a vapor film from forming.

At the same time, it reduces the concentration of bubbles on the surface, reducing boiling efficiency. To tackle that, the researchers introduced an even smaller-scale treatment as the second modification, adding bumps and ridges just nanometers in size within the surface of the hollow tubes. That increases the available surface area and promotes evaporation rates.

 

Lastly, the microscale cavities were housed in the center of a series of pillars on the material surface. These pillars speed up the drawing-off process for the liquid by adding more surface area. In combination, the boiling efficiency is significantly increased.

As the nanostructures also promote evaporation under the bubbles, and the pillars keep up a steady supply of liquid to that bubble base, a layer of water between the boiling surface and the bubbles can be maintained – enhancing the maximum heat flux.

 

"Showing that we can control the surface in this way to get enhancement is a first step," says mechanical engineer Evelyn Wang from the Massachusetts Institute of Technology. "Then the next step is to think about more scalable approaches."

 

"These kinds of structures we're making are not meant to be scaled in their current form."

Searching for an Energy Efficient Solution?

Boilersource has a wide selection of vendors that offer extremely efficient systems. No matter how big or small your operation may be, we can help find the best solution.

Taking the work from a small-scale laboratory setting into something that can be used in commercial industries won't be all that straightforward, but the researchers are confident that it can be done.

 

One challenge is going to be finding ways of creating the surface textures and the three "tiers" of modifications. The good news is that there are different approaches that can be explored, and the procedure should work for different kinds of liquids too.

 

"Those kinds of details can be changed, and that can be our next step," says Song

 

The research has been published in Advanced Materials.

DOE Issues Notice of Intent to Provide Funding for Clean Hydrogen and Grid Resilience Projects to Support Climate Goals

JULY 27, 2022

The U.S. Department of Energy (DOE) today issued a notice of intent for a potential funding opportunity to accelerate the research, development, and demonstration (RD&D) of clean-hydrogen technologies and grid resilience. The potential funding will advance the Biden Administration's goals of achieving carbon-free electricity by 2035 and net-zero carbon emissions across the entire economy by 2050.

 

This potential funding will advance the Hydrogen Shot goal of reducing the cost of clean hydrogen to $1 per 1 kilogram in 1 decade ("1 1 1"), while supporting DOE's H2@Scale initiative to develop clean and affordable hydrogen across multiple sectors in the economy and improve energy resilience. These goals will be advanced through RD&D efforts in several areas, including advanced pathways for solar-based hydrogen fuel production; technologies for high-resolution hydrogen sensing; demonstrations of materials-based hydrogen storage and transport systems; and development of high-performance, durable, low-cost fuel cell components for medium- and heavy-duty vehicles.

 

The potential funding will also seek to establish a grid resilience university consortium with agreements between universities in the United States, Canada, and Mexico to foster information sharing on best practices and cross-border dependencies. This consortium will work collaboratively with tribes, states, regions, industry, utilities, and other stakeholders to support grid resilience planning and pilot projects that can serve as a model for others.

Hydrogen’s Role in the Global Green Transition

“Oilon has more than 30 years of experience in firing fuels that contain hydrogen,” said Joonas Kattelus, chief technology officer, Oilon. “We offer several hydrogen-compatible burner models.”

DOE envisions awarding multiple financial assistance awards in the form of cooperative agreements, with the period of performance being approximately two to four years. DOE encourages applicant teams that include stakeholders within academia, industry, and national laboratories across multiple technical disciplines. Teams are also encouraged to include representation from diverse entities such as minority-serving institutions or through linkages with Opportunity Zones.

Department of Energy’s Bioenergy Office Achieves Major Biofuel Technology and Production Milestone

Josh Messner - JULY 26, 2022

The U.S. Department of Energy Bioenergy Technologies Office (BETO) has achieved a significant milestone in decreasing the minimum fuel selling price (MFSP) of drop-in biofuels, which are fuels made from biomass and other waste carbon sources, and that are compatible with existing petroleum fuel infrastructure and conventional vehicles. BETO partnered with T2C-Energy, LLC (T2C) to validate pilot-scale production of drop-in biofuels with a price of $3 per gallon of gas equivalent (GGE) and at least 60% lower greenhouse gas emissions than petroleum, using T2C’s TRIFTS® process.

 

The TRIFTS process converts anaerobic digestor produced biogas (or landfill gas) to liquid transportation fuels. TRIFTS has allowed drop-in renewable diesel fuel to reach a MFSP of $2.91/GGE without the use of credits from the U.S. Renewable Fuel Standard, California Low Carbon Fuels Standard, or other carbon credits while reducing GHG emissions by 130% when compared to traditional petroleum diesel fuel.

BIOFUEL BURNERS

Looking to reduce your carbon footprint or eliminate production waste? Boilersource will find a solution specific to your process to meet your goals. 

T2C and BETO have previously partnered on projects that have been key to advancing bioenergy technology to its current state. Previous BETO-funded Small Business Innovation Research awards allowed T2C to advance their technology to pilot scale, which was critical to reaching this important biofuel milestone. The T2C process has been thoroughly tested at the pilot scale since 2018 and uses both carbon dioxide and methane portions of biogas, using nearly 100% of biogas components as a feedstock to produce fuel. This technical achievement was verified by an independent engineering firm.

 

BETO’s efforts to reduce the price of drop-in biofuels is part of the Office of Energy Efficiency and Renewable Energy’s larger strategy for decarbonizing transportation across all modes.
