To begin, we need to define power-to-gas (PtG) in its simplest form as the conversion of electrical power into gas that can be later distributed on an as-needed basis. The objective of PtG technology is to enable the balance of supply and demand for power in electricity networks with renewable energy. Importantly, as the use of renewable energy continues to grow there will be an ever-increasing need to support ramping and smoothing of renewables and to enable storage of the over-production via transfer of PtG on an as-needed basis. Specific advantages for the continued use and growth of PtG include: PtG allows the conversion of volatile electricity into renewable, synthetic gases (H₂ or SNG) with an unmatched low carbon footprint which can be stored, transported and commercialized for mobility (green, renewable synthetic fuels) and industrial markets (green chemistry); PtG decarbonizes the gas grid by replacing fossil natural gas; PtG adds flexibility to energy systems and therefore enables efficient integration of high shares of volatile renewables into energy markets; PtG facilitates this by: Creating a connection between the power grid and the gas grid with its ample storage and transport capacity; Recharging the gas grid without timing/technical restrictions and thus allowing utilities to generate electricity and store it for use in the form of synthetic fuel at a later time and place. Global trends within the renewable energy space continue to be positive for the growing importance and expansion of PtG. Key amongst these are the required reductions in CO2 emissions to meet increasingly aggressive decarbonization requirements, the exiting of both fossil fuels and, in some countries, nuclear power generation and the increasing dependence and growth of renewables (wind and solar). On the negative side, historic factors inhibiting growth have been high capital investment combined with regulatory and infrastructure challenges. There is no getting away from the fact that there is an urgent need and growing demand to reduce the CO2 levels globally. It is alarming to note that even with the increasing global focus on reducing CO2, there is still significant use of fossil fuels causing an increase of CO2 in the atmosphere. In fact, the United Nations in October 2017 warned that “the concentration of carbon dioxide in the atmosphere increased at record speed last year (2016) to hit a level not seen for more than three million years.” A frightening statement by any measure. Figure 1 shows the impact of continued use of fossil fuels and CO2 levels related to global warming.

Having demonstrated the urgency to continue to pursue non-fossil fuel alternatives there are some examples of by-country activity on the PtG front and specifically on the intended use of gas as a key part of several countries’ renewable energy strategy. The summary also highlights the fact that global development, while promising, has been selective and limited to date. But as proactive government policies continue and costs decline, there is increasing potential for the use of the technology well beyond these early adapters. Below are some examples of countries going beyond CO2 emission requirements: Switzerland: BFE: Energy Strategy 2050 (voter approval in May 2017 —reduced dependency on fossil fuels). Swiss Gas Association: 30 percent renewable gas by 2030 Germany: Retirement of nuclear power plants by 2022 U.S.: California 50 percent renewable by 2030. (AB 2514/2868 are mandates for energy storage) Proposal SB 100 to become 100 percent renewable in California by 2045 California has invested heavily in solar power with the impact of over production of electricity which they’re sometimes forced to pay other states to take Canada: CGA’s renewable gas targets are 5 percent by 2025 and 10 percent by 2030 PtG becomes increasingly important as decarbonization intensity grows France: New government announced complete exit of coal power generation by 2023 Gas from renewable sources to be 10 percent by 2030 While PtG technology has been around for some time it is still considered a “new” and disruptive technology. Below are just two examples on the use of PtG that provide strong validation for its expanded use: In June 2013, Audi announced its opening of a 6-MW PtG facility in Germany making it the first automaker to develop a chain of sustainable energy carriers. According to the press release, “the plant uses green electricity, water and carbon dioxide to create hydrogen and a synthetic methane known as Audi e-gas which it distributes to compressed natural gas (CNG) filling stations. The Audi e-gas project demonstrates how large amounts of green electricity can be stored efficiently and independent of location by transforming it into methane gas and storing it in the natural gas network, the largest public energy storage system in Germany.” Construction of Japan’s first PtG plant was initiated in July 2017 as a key part of its efforts to reduce CO2 emissions. The press release states: “Instead of being [released into the atmosphere], the CO2 of an existing coal-fired thermal power station will be captured and effectively used for the production of synthetic natural gas (SNG). It is the objective of this test facility to prove the feasibility of large scale PtG plants.” Navigant Research indicates that a key inflection point for PtG is anticipated beginning around 2020 “as costs reach parity in more areas.”

Each year, Intersolar recognizes an individuals’ commitment to supporting the development of renewable energy with the Champion of Change AWARD, hosted in partnership with the California Solar and Storage Association (CALSSA). The Lifetime Achievement AWARD honors pioneers in clean technology and their outstanding accomplishments in advancing the adoption of renewable energy. “California’s solar industry owes a debt of gratitude to Governor Brown for his decades of support,” said Bernadette del Chiaro, executive director of CALSSA. “It was his original vision and early acceptance of solar energy as a mainstream source of energy that set the wheels of industry in motion decades ago, and still generate change today. Governor Brown has never stopped pushing for progress and change. Somehow he understands better than most public leaders that progress begets progress and that change happens one solar roof, one solar school, one solar farm at a time.” For nearly five decades, Gov. Brown has dedicated his efforts toward building an emission-free future by enforcing sustainable policies within the state of California while also contributing to national and international green initiatives. Under his leadership, California has solidified its position as a global leader in solar and clean energy, being home to one third of the country’s solar workforce and the largest solar market within the U.S. Gov. Brown appeared at Intersolar North America as a keynote speaker in San Francisco, and promoted the economic and environmental benefits role solar and renewable energy technologies offer. Gov. Brown’s commitment to solar dates back to the mid-1970s and early-1980s during his first term in office as the Governor of California, where he halted the expansion of nuclear power and promoted renewable energy. Now about to end his fourth term, Gov. Brown has been a policy trailblazer for the solar industry. In 2015, Gov. Brown signed a mandate for 50 percent renewables by 2030 inspiring many states like New York and New Jersey to follow suit. More recently, the governor formed the U.S. Climate Alliance with state governors across the country, in response to President Trump’s decision to withdraw from the Paris Climate Agreement, to further battle the effects of climate change and drive the United States’ sustainability efforts. Expanding to the international level, Gov. Brown co-founded the Under2Coalition, a global commitment to combating climate change and represents more than 1.3 billion people in GDP, 17 percent of the global population. And this year, under the governor’s leadership, California adopted the nation’s first policy requiring all new residential construction in the state to have solar installed starting in 2020. “California has long led the United States, and the world, in solar energy innovation and adoption, due in no small part to the forward-thinking policies of Gov. Brown,” said Florian Wessendorf and Daniel Strowitzki, managing directors of Intersolar North America. “We are thrilled we’ve been able to work closely with Gov. Brown and his administration over the years, and have found his comments on the industry and his actions and progressive policies inspiring. There is no one more deserving of Intersolar’s first-ever Champion of Change Lifetime Achievement AWARD.” By honoring individuals such as Gov. Brown, Intersolar and ees North America, as well as its partners, shine a light on those helping drive new energy technologies forward, and underscores the events’ commitment to supporting the solar economy in California and beyond. For more than a decade, event organizers have worked closely with organizations such as CALSSA, NAATBatt and NorCal Solar to help advocate for programs and policies important to the solar and storage industries and have also offered financial support. Off-site networking events, such as CALSSA’s annual Summerfest, serve as important fundraisers for the organizations. All proceeds from Summerfest go directly toward CALSSA. In 2017, CALSSA raised nearly $500,000 from all activities at Intersolar North America. Registration to Intersolar and ees North America’s exhibition and conference is available online. Members of the press can now apply for a media pass here. Tickets for Summerfest, as well as other networking activities including a San Francisco Bay Sailing Tour, trip to solar installations in Wine Country, and a tour of notable solar projects in San Francisco are available for purchase. All attendees are able to attend the Opening Ceremony and Champion of Change AWARD Ceremony on Tuesday, July 10 at 8:30 a.m., which will feature keynote speakers Tony Seba, author and Silicon Valley entrepreneur, and Elaine Ulrich, Ph.D. Senior Advisor U.S. Department of Energy.
