"With increasingly low clean energy costs, renewables-based hydrogen production could once again be competitive with steam methane reforming (SMR)," says Cédric Philibert, senior energy analyst at the International Energy Agency (IEA). New-built wind farms in Morocco, and solar PV in Dubai and Chile where electricity costs are around $30/MWh, according to his insight, can compete with SMR paired with carbon capture and storage.
Decentralized power generation is high on the agenda in Tanzania, with the Rural Energy Agency (REA) pleading support for individuals or companies that intend to supply ‘mini-grid electricity’. This initiative is meant to help close Tanzania's 1,290MW power deficit and give more of its rural population access to electricity.
Reflecting “higher volumes of large engines sold at a loss”, and several other one-off cash items, Rolls-Royce CEO Warren East has stressed the British manufacturer needs to do more to “ensure we drive sustainable margin improvements within the business.” Speaking at the Annual General Meeting in Derby today, he cautioned Rolls-Royce’s profit and free cash flow is will be “weighted towards the second half of the year.”
Shell, Total and others are advancing small-scale LNG-to-power projects across Southeast Asia. An ultra-shallow draft LNG carrier by Philippines-based Atlantic, Gulf & Pacific Co. (AG&P) will be a key driver for executing such projects.
Bringing more Combined Heat and Power (CHP) to the Marzahn district in eastern Berlin, Siemens has won an order to build a gas-fired combined-cycle power plant with district extraction on behalf of Vattenfall Europe Wärme AG. Scheduled to start operation in 2020, the CHP will have an electrical generating capacity of 260MW and a thermal capacity of 230MW.
With new electric devices being developed at a rapid rate, electricity will make up about 25% of final energy consumption by 2040, according to IEA estimates. Brushing climate concerns aside, Richard Zhang, technology executive at GE’s Power Conversion says: “Future electrical machines will generate power with higher density, higher efficiency and allow for a higher degree of integration.”
LNG-to-energy solutions, notably for distributed power, have made Wärtsilä one of the biggest supplier of gas- and liquid fuel-fired power stations in the 5–600 MW range. Such baseload and/or grid stability plants are used predominately as ‘wind chasers’ and ‘sunset balancers’, compensating for intermittent supply of renewable energy – soon also on the island of Aruba.
Ofgem, the UK energy regulator, has awarded National Grid’s gas distribution arm together with DNV GL a £4.8 million, three-year contract to improve the way gas bills are calculated. The new billing method seeks to specifically assign the energy content of gas, rather than using the present flow-weighted average calorific value.
Targeting customers in the offshore oil & gas industry, Siemens has introduced a new 38MW aeroderivative gas turbine that evolved from RB211 and Dresser-Rand legacies. Yet, the new SGT-A35 RB is a lightweight and has an up to 30% smaller footprint, with arguably the “highest power density in this class of turbines.”
Retirement of baseload power plants, spurred by increasingly stringent environmental regulations, as well as a rise in cross-border electricity trade is making the task of ensuring gird stability and productivity ever more complex. Dynamic voltage control helps address such challenges, says Patrick Plas, HVDC and FACTS general manager at GE Grid Solutions.
Combustion-weighted carbon intensity of all fuels used to generate electricity in the United States is now lower than that of natural gas. After averaging near 60 kg CO2/MMBtu for decades, the carbon intensity in the electric power sector fell to 48 kg CO2/MMBtu in 2016 – slightly lower than that of natural gas, which produces 53 kg CO2/MMBtu.
Bob Kraft, the man at the helm of Powerphase has signed a Memorandum of Understanding (MoU) with executives of Indonesia’s state power company PT Perusahaan Listrik Negara (PLN) to cooperate on a phased roll-out of Turbophase Dry Air Injection in the country and wider Southeast Asia. The deal was signed in connection with the Indonesia visit of US Vice President Mike Pence.
The transition from fossil fuels to renewable energy sources is the most pressing challenge in the global energy industry, says Jantine Zwinkels, Consultant at Royal HaskoningDHV. Throwing in a word of caution, she added that “the challenge for our [renewable] industry is to stand truly on its own two feet and outcompete fossil fuels without public money.”
Amandi Energy, together with consortium partner GE, is preparing to start construction works for a 200MW power plant in Aboadze, Ghana. The facility's tri-fuel 9E.04 gas turbines will be initially fuelled by light crude oil, and later switched to run on indigenous gas, once supply from Ghana’s offshore Sankofa field will be available.
The electrical grid of tomorrow will require substantially more wind and solar power. Yet integrating intermittent renewable energy with energy-on-demand generation, as well as agile power T&D networks with energy storage, is “an engineering challenge”, says Dr. Steven Chu, who served as the 12th US Secretary of Energy.
