Hydrogen Energy California

Hydrogen Energy California is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Hydrogen Energy California rather than just read about it. In short: Hydrogen Energy California (HECA) was a proposed alternative energy hydrogen power project developing with support from the U.S. Department of Energy in Kern County, California which was not approved for construction.

Key takeaways

Hydrogen Energy California belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Hydrogen Energy California to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Hydrogen Energy California from memory before moving on to harder problems.

Reference excerpt

Hydrogen Energy California (HECA) was a proposed alternative energy hydrogen power project developing with support from the U.S. Department of Energy in Kern County, California which was not approved for construction. The facility would have converted coal and refinery waste into an impure hydrogen fuel to be used to generate electricity and fertilizer. If it had become fully operational, it would have generated nearly 300MW of clean electricity and produced one million tons of locally manufactured, low-carbon fertilizer. However, significant drawbacks and cost overruns eliminated support for the proposal. The facility was to be located on 542-acre (219 ha) of prime farmland in western Kern County, about 7 miles (11 km) west of Bakersfield and 1.5 miles (2.4 km) northwest of the unincorporated community of Tupman. The site was near the Elk Hills Oil Field where the captured CO2 was to be used for enhanced oil recovery by Occidental of Elk Hills, Inc. It was expected to have employed an 2,000 union workers in temporary construction jobs and would have created approximately 200 permanent jobs. It was a project of SCS Energy LLC, an independent developer of clean power, was cofunded by the U.S. Department of Energy’s Office of Fossil Energy, and administered by the National Energy Technology Laboratory. The project was awarded a $408 million grant by the U.S. Department of Energy under Clean Coal Power Initiative Round 3.

Process The HECA project would have been an Integrated Gasification Combined Cycle (IGCC) facility using Mitsubishi's oxygen–blown gasifier technology which generates power extremely efficiently with minimal emissions. IGGC facilities differ from conventional fossil fueled power generation plants in that fossil fuels do not combust. Instead, a blend of recycled petroleum coke and coal are converted through gasification to manufacture hydrogen fuel. A Rectisol acid gas removal system was to have separated and captured more than ninety percent of the carbon dioxide (CO2) produced during the hydrogen manufacturing process. Most of the captured CO2 would then have been used for enhanced oil recovery at the nearby Elk Hills Oil Field. Some of the CO2 would have been used to manufacture fertilizer. Brackish groundwater would have served its process water needs in a Zero Liquid Discharge (ZLD) system in order to protect and conserve local freshwater sources.

Drawbacks However, most of the clean electricity produced by HECA would have been consumed by the plant's own processes at the same time it would have produced over 500 tons of criteria air pollutants in an area that already has the worst air pollution in the United States.

Schedule The project progressed through the regulatory approval process with the expectation that it would be completed and operational by 2017. On March 4, 2016, the California Energy Commission ordered the HECA application to be terminated for lack of progress.

Worked examples

Example 1 — a first encounter with Hydrogen Energy California

Start with the simplest possible case. Write down what Hydrogen Energy California claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hydrogen Energy California before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hydrogen Energy California ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hydrogen Energy California

In research: Hydrogen Energy California appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Hydrogen Energy California in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Hydrogen Energy California is common in secondary-school and first-year university syllabi. It links to neighbouring topics Energy infrastructure in California, Hydrogen economy, Power stations in California, so understanding it makes those chapters shorter.
In everyday life: Look for Hydrogen Energy California outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
