The International Energy Agency weighed in last week as bullish on the future of natural gas as a transportation fuel.

According to the Wall Street Journal, the IEA “expects natural gas use in road and maritime transportation to rise to 98 billion cubic meters by 2018, covering around 10 percent of incremental energy needs in the transport sector.”

Three factors are behind this increase in the use of natural gas for transportation, according to Maria van der Hoeven, the IEA’s executive director. These are the fuel’s “abundant supplies as well as concerns about oil dependency and air pollution.” The cost factor is particularly a driver for commercial fleet operators where current fuel prices have become more favorable for natural gas over diesel.

In the U.S., all new trucks fueled by diesel or natural gas must meet the same standards for emissions of particulate matter and nitrogen oxides. Natural gas engines for medium- and heavy-duty trucks have surpassed U.S. Environmental Protection Agency’s stringent standards for particulate matter emissions by as much as 80 percent and for nitrogen oxides by up to 35 percent. Cummins Westport, the leading producer of natural gas engines, is investigating the feasibility of reducing NOx emissions from its spark-ignited natural gas engines to levels significantly below the current federal emissions standard.

Natural gas trucks have the potential to deliver tangible greenhouse gas emissions benefits over their petroleum-based counterparts. This certainty that natural gas vehicles are able to consistently deliver on their potential climate benefits in part depends on minimizing methane leaks caused by vehicle operations, refueling and maintenance.

By: Katie Ware, EDF Senior Marketing Communications Specialist

The environmental community is abuzz with reactions to President Obama’s wide-ranging Climate Action Plan. His speech introducing the plan Tuesday sparked immediate conversations about the Keystone XL Pipeline, the coal industry, the transportation sector and half a dozen other hot button environmental issues.

For me, his speech hit home in the first minute. Addressing the crowd at Georgetown University, he said he wanted to speak directly to my generation “because the decisions we make now and in the years ahead will have a profound impact on the world that all of you inherit.”

Confident, connected and open to change (says Pew), we Millennials are 95 million strong. We elected and then re-elected Obama looking for precisely this type of bold action on issues we feel passionately about.

“Someday our children and our children’s children will look us in the eye and ask did we do all that we could when we had the chance to deal with this problem and leave them a cleaner, safer, more sustainable world. I want to be able to say yes we did. Don’t you want that?” he asked.

My answer to the President is, heck yes, and my peers are with me. Read More »

Strong Federal Air Measures Still Needed

The U.S. Environmental Protection Agency put in place last year important standards to protect public health and reduce emissions of harmful air pollutants from oil and gas storage tanks and related equipment. EPA wisely issued those standards after thousands of comments were provided by concerned public advocates for cleaner air. With oil and gas production expanding quickly, tough standards are needed now more than ever to assure air quality protections for people living near oil and gas producing areas.

Recently, EPA proposed changes to standards for storage tanks in the oil and gas sector — a major source of pollutants that contribute to smog, climate change, and other threats to public health and the environment. These changes would undermine the progress made thus far and would lead to significant and unnecessary increases in emissions of volatile organic compounds, methane, and other pollutants. EDF is urging EPA not to finalize the proposed revisions in comments filed together with Clean Air Council, Clean Air Task Force, Environmental Integrity Project, Natural Resources Defense Council and Sierra Club.

Proposed Changes to the Storage Tank Standards

Last fall, oil and gas industry groups petitioned EPA for changes to the storage tank standards, arguing that less stringent standards are needed because these tanks are even more numerous and emit at higher levels than EPA predicted when it was developing the current standards. If anything, this new information indicates the need to maintain or strengthen health-protective standards for storage tanks. EPA’s proposed changes would instead: Read More »

Investor Confidence Project Releases Enhanced Energy Efficiency Protocols

By EDF Blogs / Published: June 14, 2013

This blog post was written by guest blogger Matt Golden, Senior Energy Finance Consultant.

The EDF Investor Confidence Project (ICP) is a multi-year initiative to help spur growth in the commercial energy efficiency retrofit market by reducing transaction costs and engineering overhead, and increasing the reliability and consistency of savings. EDF has worked with a cross-functional team of industry experts to assemble existing technical standards and best practices into a straightforward Energy Performance Protocol (EPP) that defines a standard investment quality energy efficiency project to enable deal-flow and investment.

In November of 2012, we released the initial version of the Energy Performance Protocol for Large Commercial (EPP-LC). We received encouraging reviews from industry allies and many industry leaders have committed to join our growing ICP Ally program, a broad based network of organizations that helps us develop, test, and implement the ICP Protocols.

New Release: Large Commercial – Version 1.1

Building on our initial success and market feedback, ICP is now releasing a new and updated version 1.1 of the EPP-LC, which incorporates a wide array of important improvements that will streamline the project development process and improve results.

Our ICP team is incredibly grateful to all individuals that contributed their time and energy to this process resulting in a more streamlined protocol, especially our committed team of experts who dedicated untold hours and contributed a wide array of industry, research, and public sector experience.

Energy From The Sea: Closer Than You Think

By EDF Blogs / Published: June 12, 2013

This commentary, authored by Rod Fujita, originally appeared on EDF Voices.

The ocean absorbs energy from the sun, stores it, and then releases it slowly. Sounds like a prescription for meeting the world’s energy needs, since the ocean is the largest feature of our planet. But can ocean energy be tapped in a way that doesn’t create more problems than it solves?

That’s the promise behind a recently announced deal between Lockheed Martin and Reignwood Group, a resort developer based in Beijing. The two companies will develop a 10-megawatt power plant using ocean thermal energy conversion (OTEC) technology in waters off southern China’s Hainan Island. Construction is expected to be completed in 2017.

The process

Scientists have long been interested in the potential for generating energy from the difference in temperature between warm surface waters and deep water. When this difference is large – for example, in tropical locations with narrow continental shelves – the warm water can be used to convert a liquid (like ammonia) into steam. The steam drives a turbine, producing electricity, and then is recondensed into a liquid using cold water pumped up from the deep ocean so that the cycle can be repeated.

Benefits

The OTEC process can produce a number of benefits in addition to clean electricity. The large volumes of cold water pumped through the system can be used to cool buildings, saving on air conditioning (and associated greenhouse gas emissions from this major energy consumer). Lots of freshwater condenses on the cold water pipes, especially in humid tropical environments – so much that it can become a viable supplement to local water supplies or even the major water source for local communities.

White House Leadership Summit On Women, Climate And Energy

By EDF Blogs / Published: June 6, 2013

This commentary, authored by Katie Walsh, originally appeared on EDF Climate Corps.

After an incredible week of EDF Climate Corps Training last month, I had the opportunity to speak at the White House for an inaugural one-day summit on Women, Climate and Energy organized by the U.S. Department of Energy and the White House Office of Public Engagement.

I joined a distinguished group of 100 women from business, research, government and the nonprofit sector to discuss our work in climate and energy. I provided the closing address highlighting the need to bridge silos by opening up our climate change ‘narratives’ to better engage diverse audiences as well as use tactics that push the envelope on climate change action.

Debating Solutions – Not Science

Newly appointed Energy Secretary Ernest Moniz opened the summit with a statement that I couldn’t agree with more: “I’m not here to debate the undebatable; climate change is real and urgent and science demands a prudent response. Now the question is: what are the solutions? This is the legitimate debate; let’s debate the solutions, as opposed to the drivers.” On top of the list of solutions he noted the Obama Administration working on is energy efficiency – in buildings, appliances, vehicles and the industrial sector. Efficiency gains provide win-win solutions. An example is the more than $2 trillion dollars to be saved from appliance standards revisions along with the associated carbon emission reductions. Another example is the $1.2 billion in energy efficiency savings EDF Climate Corps fellows have identified in that last 5 years. Read More »
