Earlier this month, the U.S. Department of Energy announced another $13 million in funding to seven projects that are developing hydropower as a clean energy source. A Houston startup made the list of recipients.

“For more than a century, Americans have harnessed the power of water to electrify our communities, and it’s a critical renewable energy source that will help us reach our climate goals,” U.S. Secretary of Energy Jennifer M. Granholm says in a news release. “President Biden’s Investing in America agenda will help to expand the use of hydropower, increasing access to affordable, clean power and creating good-paying jobs.”

Houston-based Quidnet Energy Inc. received a little over $2 million for its project, entitled "Energy Storage Systems for Overpressure Environments," which is taking place in East Texas. The company, founded in 2013, is using water storage to power carbon-free electric grid approach to energy. As the DOE notes, the "low-cost form of long-duration electricity storage uses existing wellbores, which offers an opportunity to repurpose legacy oil and gas assets," per the release.

It's not the first Quidnet has secured funding from the DOE. Last fall, the company earned a $10 million grant from the organization's Advanced Research Projects Agency-Energy, or ARPA-E, program. Quidnet is also venture backed, with its most recent raise, a $10 million series B round, closing in 2020 and including participation from Bill Gates-backed Breakthrough Energy Ventures and Canada-based Evok Innovations.

The DOE's other PSH, or pumped storage hydropower, grants were announced as follows.

  • The Electric Power Research Institute, based in Palo Alto, California, secured $2.3 million to test "a turbine/generator system designed to add power-generating infrastructure to non-powered dams" in Iowa, per the release.
  • Atlanta-based Emrgy received $1.6 million to "develop a turbine to generate hydropower at non-powered dams where the water drop is less than 30 feet or in low-flow conduits, such as existing irrigation canals," in Washington.
  • Another Atlanta company, Georgia Power Co. is getting just under $2.9 million to develop and deploy PSH facilities across the country with its utility-scale solution to retrofit traditional hydropower facilities to serve as PSH facilities. The site the company will demonstrate it's tech is in Salem, Alabama.
  • RCAM Technologies, based in Boulder, Colorado, will work on offshore PSH technology in San Pedro, California, with its $4 million grant.
  • Drops for Watts received $243,540 to "develop a low-impact, modular system to generate hydropower from existing irrigation infrastructure" in Sagle, Idaho.
  • In Atlanta, Turbine Logic will use its nearly $200,000 in funding to utilize digital twin technology "to better predict common maintenance needs in hydropower turbines."

How is energy produced?

ENERGY 101

Many think of the Energy Industry as a dichotomy–old vs. new, renewable vs. nonrenewable, good vs. bad. But like most things, energy comes from an array of sources, and each kind has its own unique benefits and challenges. Understanding the multi-faceted identity of currently available energy sources creates an environment in which new ideas for cleaner and more sustainable energy sourcing can proliferate.

At a high level, energy can be broadly categorized by the process of extracting and converting it into a useful form.

Energy Produced from Chemical Reaction

Energy derived from coal, crude oil, natural gas, and biomass is primarily produced as a result of bonds breaking during a chemical reaction. When heated, burned, or fermented, organic matter releases energy, which is converted into mechanical or electrical energy.

These sources can be stored, distributed, and shared relatively easily and do not have to be converted immediately for power consumption. However, the resulting chemical reaction produces environmentally harmful waste products.

Though the processes to extract these organic sources of energy have been refined for many years to achieve reliable and cheap energy, they can be risky and are perceived as invasive to mother nature.

According to the 2022 bp Statistical Review of World Energy, approximately 50% of the world’s energy consumption comes from petroleum and natural gas; another 25% from coal. Though there was a small decline in demand for oil from 2019 to 2021, the overall demand for fossil fuels remained unchanged during the same time frame, mostly due to the increase in natural gas and coal consumption.

Energy Produced from Mechanical Reaction

Energy captured from the earth’s heat or the movement of wind and water results from the mechanical processes enabled by the turning of turbines in source-rich environments. These turbines spin to produce electricity inside a generator.

Solar energy does not require the use of a generator but produces electricity due to the release of electrons from the semiconducting materials found on a solar panel. The electricity produced by geothermal, wind, solar, and hydropower is then converted from direct current to alternating current electricity.

Electricity is most useful for immediate consumption, as storage requires the use of batteries–a process that turns electrical energy into chemical energy that can then be accessed in much the same way that coal, crude oil, natural gas, and biomass produce energy.

Energy Produced from a Combination of Reactions

Hydrogen energy comes from a unique blend of both electrical and chemical energy processes. Despite hydrogen being the most abundant element on earth, it is rarely found on its own, requiring a two-step process to extract and convert energy into a usable form. Hydrogen is primarily produced as a by-product of fossil fuels, with its own set of emissions challenges related to separating the hydrogen from the hydrocarbons.

Many use electrolysis to separate hydrogen from other elements before performing a chemical reaction to create electrical energy inside of a contained fuel cell. The electrolysis process is certainly a more environmentally-friendly solution, but there are still great risks with hydrogen energy–it is highly flammable, and its general energy output is less than that of other electricity-generating methods.

Energy Produced from Nuclear Reaction

Finally, energy originating from the splitting of an atom’s nucleus, mostly through nuclear fission, is yet another way to produce energy. A large volume of heat is released when an atom is bombarded by neutrons in a nuclear power plant, which is then converted to electrical energy.

This process also produces a particularly sensitive by-product known as radiation, and with it, radioactive waste. The proper handling of radiation and radioactive waste is of utmost concern, as its effects can be incredibly damaging to the environment surrounding a nuclear power plant.

Nuclear fission produces minimal carbon, so nuclear energy is oft considered environmentally safe–as long as strict protocols are followed to ensure proper storage and disposal of radiation and radioactive waste.

Nuclear to Mechanical to Chemical?

Interestingly enough, the Earth’s heat comes from the decay of radioactive materials in the Earth’s core, loosely linking nuclear power production back to geothermal energy production.

It’s also clear the conversion of energy into electricity is the cleanest option for the environment, yet adequate infrastructure remains limited in supply and accessibility. If not consumed immediately as electricity, energy is thus converted into a chemical form for the convenience of storage and distribution it provides.

Perhaps the expertise and talent of Houstonians serving the flourishing academic and industrial sectors of energy development will soon resolve many of our current energy challenges by exploring further the circular dynamic of the energy environment.

ExxonMobil lands major partnership for clean hydrogen facility in Baytown

power deal

Exxon Mobil and Japanese import/export company Marubeni Corp. have signed a long-term offtake agreement for 250,000 tonnes of low-carbon ammonia per year from ExxonMobil’s forthcoming facility in Baytown, Texas.

“This is another positive step forward for our landmark project,” Barry Engle, president of ExxonMobil Low Carbon Solutions, said in a news release. “By using American-produced natural gas we can boost global energy supply, support Japan’s decarbonization goals and create jobs at home. Our strong relationship with Marubeni sets the stage for delivering low-carbon ammonia from the U.S. to Japan for years to come."

The companies plan to produce low-carbon hydrogen with approximately 98% of CO2 removed and low-carbon ammonia. Marubeni will supply the ammonia mainly to Kobe Power Plant, a subsidiary of Kobe Steel, and has also agreed to acquire an equity stake in ExxonMobil’s low-carbon hydrogen and ammonia facility, which is expected to be one of the largest of its kind.

The Baytown facility aims to produce up to 1 billion cubic feet daily of “virtually carbon-free” hydrogen. It can also produce more than 1 million tons of low-carbon ammonia per year. A final investment decision is expected in 2025 that will be contingent on government policy and necessary regulatory permits, according to the release.

The Kobe Power Plant aims to co-fire low-carbon ammonia with existing fuel, and reduce CO2 emissions by Japan’s fiscal year of 2030. Marubeni also aims to assist the decarbonization of Japan’s power sector and steel manufacturing industry, chemical industry, transportation industry and various others sectors.

“Marubeni will take this first step together with ExxonMobil in the aim of establishing a global low-carbon ammonia supply chain for Japan through the supply of low-carbon ammonia to the Kobe Power Plant,” Yoshiaki Yokota, senior managing executive officer at Marubeni Corp., added in the news release. “Additionally, we aim to collaborate beyond this supply chain and strive towards the launch of a global market for low-carbon ammonia. We hope to continue to actively cooperate with ExxonMobil, with a view of utilizing this experience and relationship we have built to strategically decarbonize our power projects in Japan and Southeast Asia in the near future.”

Houston expert: The role of U.S. LNG in global energy markets

guest column

The debate over U.S. Liquefied Natural Gas (LNG) exports is too often framed in misleading, oversimplified terms. The reality is clear: LNG is not just a temporary fix or a bridge fuel, it is a fundamental pillar of global energy security and economic stability. U.S. LNG is already reducing coal use in Asia, strengthening Europe’s energy balance, and driving economic growth at home. Turning away from LNG exports now would be a shortsighted mistake, undermining both U.S. economic interests and global energy security.

Ken Medlock, Senior Director of the Baker Institute’s Center for Energy Studies, provides a fact-based assessment of the U.S. LNG exports that cuts through the noise. His analysis, consistent with McKinsey work, confirms that U.S. LNG is essential to balancing global energy markets for the decades ahead. While infrastructure challenges and environmental concerns exist, the benefits far outweigh the drawbacks. If the U.S. fails to embrace its leadership in LNG, we risk giving up our position to competitors, weakening our energy resilience, and damaging national security.

LNG Export Licenses: Options, Not Guarantees

A common but deeply flawed argument against expanding LNG exports is the assumption that granting licenses guarantees unlimited exports. This is simply incorrect. As Medlock puts it, “Licenses are options, not guarantees. Projects do not move forward if they are unable to find commercial footing.”

This is critical: government approvals do not dictate market outcomes. LNG projects must navigate economic viability, infrastructure feasibility, and global demand before becoming operational. This reality should dispel fears that expanded licensing will automatically lead to an uncontrolled surge in exports or domestic price spikes. The market, not government restrictions, should determine which projects succeed.

Canada’s Role in U.S. Gas Markets

The U.S. LNG debate often overlooks an important factor: pipeline imports from Canada. The U.S. and Canadian markets are deeply intertwined, yet critics often ignore this reality. Medlock highlights that “the importance to domestic supply-demand balance of our neighbors to the north and south cannot be overstated.”

Infrastructure Constraints and Price Volatility

One of the most counterproductive policies the U.S. could adopt is restricting LNG infrastructure development. Ironically, such restrictions would not only hinder exports but also drive up domestic energy prices. Medlock’s report explains this paradox: “Constraints that either raise development costs or limit the ability to develop infrastructure tend to make domestic supply less elastic. Ironically, this has the impact of limiting exports and raising domestic prices.”

The takeaway is straightforward: blocking infrastructure development is a self-inflicted wound. It stifles market efficiency, raises costs for American consumers, and weakens U.S. competitiveness in global energy markets. McKinsey research confirms that well-planned infrastructure investments lead to greater price stability and a more resilient energy sector. The U.S. should be accelerating, not hindering, these investments.

Short-Run vs. Long-Run Impacts on Domestic Prices

Critics of LNG exports often confuse short-term price fluctuations with long-term market trends. This is a mistake. Medlock underscores that “analysis that claims overly negative domestic price impacts due to exports tend to miss the distinction between short-run and long-run elasticity.”

Short-term price shifts are inevitable, driven by seasonal demand and supply disruptions. But long-term trends tell a different story: as infrastructure improves and production expands, markets adjust, and price impacts moderate. McKinsey analysis suggests supply elasticity increases as producers respond to price signals. Policy decisions should be grounded in this broader economic reality, not reactionary fears about temporary price movements.

Assessing the Emissions Debate

The argument that restricting U.S. LNG exports will lower global emissions is fundamentally flawed. In fact, the opposite is true. Medlock warns against “engineering scenarios that violate basic economic principles to induce particular impacts.” He emphasizes that evaluating emissions must be done holistically. “Constraining U.S. LNG exports will likely mean Asian countries will continue to turn to coal for power system balance,” a move that would significantly increase global emissions.

McKinsey’s research reinforces that, on a lifecycle basis, U.S. LNG produces fewer emissions than coal. That said, there is room for improvement, and efforts should focus on minimizing methane leakage and optimizing gas production efficiency.

However, the broader point remains: restricting LNG on environmental grounds ignores the global energy trade-offs at play. A rational approach would address emissions concerns while still recognizing the role of LNG in the global energy system.

The DOE’s Commonwealth LNG Authorization

The Department of Energy’s recent conditional approval of the Commonwealth LNG project is a step in the right direction. It signals that economic growth, energy security, and market demand remain key considerations in regulatory decisions. Medlock’s analysis makes it clear that LNG exports will be driven by market forces, and McKinsey’s projections show that global demand for flexible, reliable LNG is only increasing.

The U.S. should not limit itself with restrictive policies when the rest of the world is demanding more LNG. This is an opportunity to strengthen our position as a global energy leader, create jobs, and ensure long-term energy security.

Conclusion

The U.S. LNG debate must move beyond fear-driven narratives and focus on reality. The facts are clear: LNG exports strengthen energy security, drive economic growth, and reduce global emissions by displacing coal.

Instead of restrictive policies that limit LNG’s potential, the U.S. should focus on expanding infrastructure, maintaining market flexibility, and supporting innovation to further reduce emissions. The energy transition will be shaped by market realities, not unrealistic expectations.

The U.S. has an opportunity to lead. But leadership requires embracing economic logic, investing in infrastructure, and ensuring our policies are guided by facts, not political expediency. LNG is a critical part of the global energy landscape, and it’s time to recognize its long-term strategic value.

Woodlands company licenses free patents to ERCOT to boost grid reliability

grid deal

Lancium, a company based in The Woodlands that specializes in infrastructure for connecting large-scale data centers to power grids, is licensing a portfolio of patents to the Electric Reliability Council of Texas (ERCOT) at no cost.

In a news release, Lancium says the intellectual property agreement “ensures ERCOT can sublicense these patents freely, thereby expanding market participation opportunities without risk of patent infringement disputes.”

“This agreement exemplifies Lancium’s dedication to supporting grid stability and innovation across the ERCOT region,” Michael McNamara, CEO of Lancium, said in a news release. “While these patents represent significant technological advancements, we believe that enabling ERCOT and its market participants to operate freely is more valuable for the long-term reliability and resilience of the Texas grid.”

The licensed patents encompass Lancium technologies that support load resources in ERCOT’s market, which covers about 90 percent of Texas. Specifically, the patents deal with controllable load resources. A controlled load resource allows ERCOT and other grids to increase or decrease power consumption during peak periods or emergencies.

ERCOT predicts power demand in Texas will nearly double by 2030, “in part due to more requests to plug into the grid from large users like data centers, crypto mining facilities, hydrogen production plants, and oil and gas companies,” The Texas Tribune reported.
